Production and evaluation of novel functional extruded corn snacks fortified with ginger, bay leaves and turmeric powder was written by Amer, Sara Adel;Rizk, Ayat Ebrahim. And the article was included in Food Production, Processing and Nutrition in 2022.Product Details of 33171-05-0 The following contents are mentioned in the article:

Extruded corn snacks are accepted by all human ages especially children, but they have low functional value. Therefore, corn extruded snacks contain rich nutraceuticals dried herbs including Laurus nobilis (T1), Curcuma longa (T2), Zingiber officinale Roscoe (T3), and the mixture of these herbs (T4) were manufactured and analyzed. The results declared that all the herbal extruded corn snacks had significantly higher ash, fibers, minerals, and vitamins A and B6. For minerals, the highest percent of increase compared to control was achieved by Fe, K, Ca, Zn content in order, being the highest in T4. The contents of Vitamin A and B6 were ranged from 283 to 445 IU/100 g and from 0.01 to 0.08 mg/100 g for the herbal extrudates, resp. The increased percent in herbal corn snacks relative to control ranged from 743 to 452%, 188 to 17.6%, and from 313 to 99% for total phenolics, flavonoids, and antioxidant activity. Besides, the highest number of phenolic compounds was recorded in T4. Despite the fact that approx. all herbal extruded products had good texture and color characteristics, the best formulation was T2 and T4 corn snacks. Furthermore, the extruded products were microbiol. safe for up to 9 mo. The formulation of herbal-corn snacks could fulfill consumers′ requirement for ready-to-eat-healthy foods with acceptable sensory attributes and also economically suitable for the food industry. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Product Details of 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Product Details of 33171-05-0

A new synthetic biology approach for the production of curcumin and its glucoside in Atropa belladonna hairy roots was written by Singh, Sailendra;Pandey, Pallavi;Akhtar, Qussen Md.;Negi, Arvind Singh;Banerjee, Suchitra. And the article was included in Journal of Biotechnology in 2021.Application In Synthesis of Bisdemethoxycurcumin The following contents are mentioned in the article:

Curcumin has ignited global interest as an elite drugable mol., owing to its time-honoured pharmacol. activities against diverse human ailments. Limited natural accessibility and poor oral bioavailability caused major hurdles in the curcumin-based drug development process. We report the first successful testimony of curcumin and its glucoside synthesis in Atropa belladonna hairy roots (HR) through metabolic engineering. Re-routing the inherent biosynthetic precursors of the phenylpropanoid pathway of A. belladonna by heterologous expression of key curcumin biosynthetic pathway genes (i.e., Diketide-CoA synthase-DCS and Curcumin synthase-CURS3) and glucosyltransferase gene (CaUGT2) resulted in the production of curcumin and its glucoside in HR clones. Under shake-flask cultivation, the PGD2-HR1clone bearing DCS/ CURS3 genes showed the maximum curcumin yield (180.62 ± 4.7 μg/g DW), while the highest content of curcumin monoglucoside (32.63 ± 2.27 μg/g DW) along with curcumin (67.89 ± 2.56 μg/g DW) were noted in the PGD3-HR3 clone co-expressing DCS/CURS3 and CaUGT2 genes. Bioreactor up-scaling showed yield improvements in the PGD2-HR1 (2.3 fold curcumin) and the PGD3-HR3 clone (0.9 and 1.65 folds of curcumin-monoglucoside and curcumin resp.). These findings proved the advantageous use of HR cultures as the production source for curcumin and its glucoside, which remained unexplored so far. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Application In Synthesis of Bisdemethoxycurcumin).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Application In Synthesis of Bisdemethoxycurcumin

Chagas disease (CD) is a neglected protozoan infection caused by Trypanosoma cruzi, which affects about 7 million people worldwide. There are two available drugs in therapeutics, however, they lack effectiveness for the chronic stage-characterized mainly by cardiac (i.e., cardiomyopathy) and digestive manifestations (i.e., megaesophagus, megacolon). Due to the involvement of the immuno-inflammatory pathways in the disease′s progress, compounds exhibiting antioxidant and anti-inflammatory activity seem to be effective for controlling some clin. manifestations, mainly in the chronic phase. Resveratrol (RVT) and curcumin (CUR) are natural compounds with potent antioxidant and anti-inflammatory properties and their cardioprotective effect have been proposed to have benefits to treat CD. Such effects could decrease or block the progression of the disease′s severity. The purpose of this systematic review is to analyze the effectiveness of RVT and CUR in animal and clin. research for the treatment of CD. The study was performed according to PRISMA guidelines and it was registered on PROSPERO (CDR42021293495). The results did not find any clin. study, and the animal research was analyzed according to the SYRCLES risk of bias tools and ARRIVE 2.0 guidelines. We found 9 eligible reports in this study. We also discuss the potential RVT and CUR derivatives for the treatment of CD as well. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Related Products of 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Related Products of 33171-05-0

Despite its potent anti-amyloid properties, the utility of curcumin (Cur) for the treatment of Alzheimer’s disease (AD) is limited due to its low bioavailability. Tetrahydrocurcumin (THC), a more stable metabolite has been found in Cur-treated tissues. We compared the anti-amyloid and neuroprotective properties of curcumin, bisdemethoxycurcumin (BDMC), demethoxycurcumin (DMC) and THC using mol. docking/dynamics, in-silico and in vitro studies. We measured the binding affinity, H-bonding capabilities of these compounds with amyloid beta protein (Aβ). Dot blot assays, photo-induced cross linking of unmodified protein (PICUP) and transmission electron microscopy (TEM) were performed to monitor the Aβ aggregation inhibition using these compounds Neuroprotective effects of these derivatives were evaluated in N2a, CHO and SH-SY5Y cells using Aβ42 (10μM) as a toxin. Finally, Aβ-binding capabilities were compared in the brain tissue derived from the 5x FAD mouse model of AD. We observed that THC had similar binding capability and Aβ aggregation inhibition such as keto/enol Cur and it was greater than BDMC and DMC. All these derivatives showed a similar degree of neuroprotection in vitro and labeled Aβ-plaques ex vivo. Overall, ECur and THC showed greater anti-amyloid properties than other derivatives Therefore, THC, a more stable and bioavailable metabolite may provide greater therapeutic efficacy in AD than other turmeric derivatives This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Related Products of 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Related Products of 33171-05-0

Osteoarthritis (OA) is a musculoskeletal disorder mainly found in elderly individuals. Modern treatment of OA, like nonsteroidal anti-inflammatory drugs, corticosteroids, hyaluronic acid injections, etc., is linked to long-term side effects. We evaluated the anti-osteoarthritic properties of a novel joint health formula (JHF) containing Bisdemethoxycurcumin enriched curcumin, 3-O-Acetyl-11-keto-beta-Boswellic acid-enriched Boswellia, and Ashwagandha in monosodium iodoacetate (MIA)-induced knee OA in rats. Twenty-eight female rats were distributed into four groups: Control, OA, OA + JHF (100 mg/kg), and OA + JHF (200 mg/kg). JHF decreased the right joint diameters but increased the paw area and stride length compared to the OA group with no treatment. JHF significantly reduced the arthritic conditions after four weeks of supplementation (p < 0.05). JHF significantly decreased TNF-α, IL-1β, IL-10, COMP, and CRP in the serum of osteoarthritic rats (p < 0.0001). We observed reduced lipid peroxidation but increased SOD, GSH-Px, and CAT activities in response to JHF treatment in OA animals. JHF down-regulated MMP-3, COX-2, and LOX-5 and improved the histol. structure of the knee joint of osteoarthritic rats. JHF demonstrated a protective effect against osteoarthritis, possibly due to anti-inflammatory and antioxidant activity in exptl. induced osteoarthritis in rats, and could be an effective option in the management of OA.

Since the emergence of novel Coronavirus (SARS-CoV-2) infection in Wuhan, China in Dec. 2019, it has now spread to over 205 countries. Considering the current state of affairs, there is an urgent unmet medical need to identify novel and effective approaches for the prevention and treatment of COVID-19 by re-evaluating the knowledge of traditional medicines and repurposing of drugs. Here, we used mol. docking and mol. dynamics simulation approach to explore the beneficial roles of phytochems. and active pharmacol. agents present in the Indian herbs which are widely used in the preparation of Ayurvedic medicines in the form of Kadha to control various respiratory disorders such as cough, cold and flu. Our study has identified an array of phytochems. present in these herbs which have significant docking scores and potential to inhibit different stages of SARS-CoV-2 infection as well as other Coronavirus target proteins. The phytochems. present in these herbs possess significant anti-inflammatory property. Apart from this, based on their pharmaceutical characteristics, we have also performed in-silico drug-likeness and predicted pharmacokinetics of the selected phytochems. found in the Kadha. Overall our study provides scientific justification in terms of binding of active ingredients present in different plants used in Kadha preparation with viral proteins and target proteins for prevention and treatment of the COVID-19.

Virtual screening of curcumin and its analogs against the spike surface glycoprotein of SARS-CoV-2 and SARS-CoV was written by Patel, Ashish;Rajendran, Malathi;Shah, Ashish;Patel, Harnisha;Pakala, Suresh B.;Karyala, Prashanthi. And the article was included in Journal of Biomolecular Structure and Dynamics in 2022.Name: Bisdemethoxycurcumin The following contents are mentioned in the article:

The novel corona virus SARS-CoV-2 and the 2002 SARS-CoV have 74% identity and use similar mechanisms to gain entry into the cell. Both the viruses enter the host cell by binding of the viral spike glycoprotein to the host receptor, angiotensin converting enzyme 2 (ACE2). Targeting entry of the virus has a better advantage than inhibiting the later stages of the viral life cycle. The crystal structure of the SARS-CoV (6CRV: full length S protein) and SARS-CoV-2 Spike proteins (6M0J: Receptor binding domain, RBD) was used to determine potential small mol. inhibitors. Curcumin, a naturally occurring phytochem. in Curcuma longa, is known to have broad pharmacol. properties. In the present study, curcumin and its derivatives were docked, using Autodock 4.2, onto the 6CRV and 6M0J to study their capability to act as inhibitors of the spike protein and thereby, viral entry. The curcumin and its derivatives displayed binding energies, ΔG, ranging from -10.98 to -5.12 kcal/mol (6CRV) and -10.01 to -5.33 kcal/mol (6M0J). The least binding energy was seen in bis-demethoxycurcumin with: ΔG = -10.98 kcal/mol (6CRV) and -10.01 kcal/mol (6M0J). A good binding energy, drug likeness and efficient pharmacokinetic parameters suggest the potential of curcumin and few of its derivatives as SARS-CoV-2 spike protein inhibitors. However, further research is necessary to investigate the ability of these compounds as viral entry inhibitors. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Name: Bisdemethoxycurcumin).

Disposal of the turmeric waste commonly known as turmeric spent oleoresin (TSO) left after separation of curcuminoids has been considered as serious concern and has attracted scientific community at large for its sustainable utilization. The fractionation of TSO was achieved using column chromatog. and the fractions thus obtained were characterized using HPLC and LCMS-qToF techniques. The isolated fractions and turmeric were examined for their antioxidant activity employing standard procedures such as DPPH scavenging assay, ABTS scavenging assay, FRAP assay and Phosphomolybdate assays. Antimicrobial potential of TSO and isolates was performed against different microbial strains using the broth dilution method. Chem. characterization of TSO revealed the presence of ferulic acid, myristicin, furanodience, cyclocurcumin, 6-methoxy-2-[2-(3methoxyphenyl) ethyl] chromone, dihydrocurcumin, bisabolocurcumin ether, terpecurcumin Q, curcumin, cyclobisdesmethoxycurcumin, and bisdemethoxycurcumin. The highest antimicrobial activity was recorded for Fraction 1 (F1) (Inhibitory zone diameter (IZD) = 25.33 ± 0.33 mm), Fraction 6 (F6) (IZD = 23.67 ± 0.33 mm), Fraction 7 (F7) (IZD = 22.67 ± 0.33 mm), Fraction 9 (F9) (IZD = 24.00 ± 00 mm) and Fraction 11 (F11) (IZD = 22.33 ± 0.67 mm) against Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), Pseudomonas aeruginosa (P. aeruginosa), Candida albicans (C. albicans), and Salmonella abony (S. abony) resp.

Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Development and clinical trials on anti-inflammatory effect of transdermal patch containing a combination of Kaempferia parviflora and Curcuma longa extracts was written by Tuntiyasawasdikul, Sarunya;Sripanidkulchai, Bungorn. And the article was included in Journal of Drug Delivery Science and Technology in 2022.Electric Literature of C19H16O4 The following contents are mentioned in the article:

Kaempferia parviflora and Curcuma longa have been widely reported to have a potent anti-inflammatory effect. However, both extracts have been shown to have low bioavailability and high-level first pass metabolism upon oral administration. This study aimed to develop transdermal delivery of a combination of both extracts in matrix-patch formulations with five different volatile oils which possess analgesic and anti-inflammatory properties. Fourteen formulations exhibited good physicochem. properties and stability. The release of methoxyflavones increased significantly when the concentration of PVP (polyvinylpyrrolidone) in the patches increased. The drug release kinetics were best-fitted with the zero-order and Higuchi models, depending on the amount of PVP. When combined with Curcuma longa, the patch provided the highest accumulation of methoxyflavones and curcuminoids within the skin. In the clin., randomized controlled trial, a significant pain improvement was found after seven days of application on the pain area. The pain scores decreased from 5.84 ± 1.57 to 2.74 ± 1.37 and the mean pain pressure threshold increased significantly from 1.79 ± 0.51 N to 2.55 ± 0.41 N. Our results indicated that the developed herbal patches were useful for transdermal application and can be considered as an alternative treatment for pain relief, highlighted by a decrease in pain intensity and an increase in pain tolerance, without skin irritation.

Some polyphenol-derived metabolites reach human breast cancer (BC) tissues at concentrations that induce cell senescence. However, this is unknown for isoflavones, curcuminoids, and lignans. Here, their metabolic profiling in normal (NT) and malignant (MT) mammary tissues of newly-diagnosed BC patients and the tissue-occurring metabolite’s anticancer activity are evaluated. Patients (n = 26) consumed 3 capsules/day (turmeric, red clover, and flaxseed extracts plus resveratrol; 296.4 mg phenolics/capsule) from biopsy-confirmed diagnosis to surgery (5 ± 2 days) or did not consume capsules (n = 13). NT and MT, blood, and urine are analyzed by UPLC-QTOF-MS using targeted metabolomics. Anticancer activity was tested in MCF-7 and MDA-MB-231 BC cells. Mainly phase-II metabolites were detected (108, 84, 49, and 47 in urine, plasma, NT, and MT, resp.). Total metabolite concentrations reached 10.7 ± 11.1 and 2.5 ± 2.4μmol L^-1 in NT and MT, resp. Free curcumin, but not its glucuronide, was detected in the tissues (1.1 ± 1.8 and 0.2 ± 0.2μmol L^-1 in NT and MT, resp.). Breast tissue-occurring metabolite’s antiproliferation was mainly exerted in p53-wild-type MCF-7 cells by curcuminoids through cell cycle arrest, senescence, and apoptosis induction via p53/p21 induction, while isoflavone-derived metabolites exerted estrogenic-like activity. Curcuminoids could be coadjuvants that might help fight BC upon regular consumption.
