In 2022,Kaya, Busra; Kalindemirtas, Ferdane Danisman; Ertik, Onur; Yanardag, Refiye; Kuruca, Serap Erdem; Ulkuseven, Bahri published an article in Chemico-Biological Interactions. The title of the article was 《New thiosemicarbazone-based Zinc(II) complexes. In vitro cytotoxicity competing with cisplatin on malignant melanoma A375 cells and its relation to neuraminidase inhibition》.Recommanded Product: 2-Hydroxy-4-methoxybenzaldehyde The author mentioned the following in the article:

New thiosemicarbazone-based zinc(II) complexes were synthesized to study their cytotoxicity on A375 malignant melanoma cells. The complexes containing salicylidene (Zn1a), 3-methoxy-salicylidene (Zn1b) or 4-methoxy-salicylidene (Zn1c) moiety were characterized by anal. and spectroscopic methods. Anticancer potential of the complexes was determined by MTT test and HUVEC endothelial cells line was used to comprehend the effect on normal cells. Zn1b with an IC50 of 13 μM was found to be highly cytotoxic against A375 cancer cells, more effective than cisplatin (IC50: 37 μM). Zn1a and Zn1c did not have a neg. effect on cell viability in the normal cells and gave the impression that they are more advantageous than cisplatin in this respect. Further, the ability of Zn1a-c to inhibit neuraminidase enzyme and its role in cytotoxicity was discussed. The test revealed that the Zn1b with 3-methoxy substituent exhibited higher inhibition activity against the neuraminidase than the Zn1a and Zn1c as analogical to the cytotoxicity results. In neuraminidase inhibition, IC50 values of Zn1b and Zn1c were 14 and 66 μM, resp. These concentrations were very close to the cytotoxicity concentrations for Zn1b and Zn1c. The findings may indicate the role of neuraminidase enzyme inhibition in cell death for Zn1b and Zn1c.

The article was titled 《Bioactive sulfonyl hydrazones with alkyl derivative: Characterization, ADME properties, molecular docking studies and investigation of inhibition on choline esterase enzymes for the diagnosis of Alzheimers disease》, and you may find the article in Chemico-Biological Interactions.Reference of 2-Hydroxy-4-methoxybenzaldehyde The information in the text is summarized as follows:

In this work, new sulfonylhydrazone compounds with alkyl derivatives (SH1- SH4 series) were synthesized via a green chem. method, and their inhibition effects on acetylcholinesterase and butyrylcholinesterase (AChE, BChE) were determined in vitro. This work was designed in two stages; in the first stage, using compounds that contain both sulfonamide and hydrazine groups which have important pharmacol. properties, a series of sulfonyl hydrazone with alkyl derivatives (SH1- SH4) were synthesized with a method that is less time-consuming and more environmentalist that was by using different substitute groups containing aldehyde and ketone compounds The structures of the synthesized compounds were characterized by elemental analyses, 1H NMR, 13C NMR, FT-IR methods. In the second stage, the effects of the synthesized sulfonyl hydrazones with alkyl derivatives on acetylcholinesterase and butyrylcholinesterase enzymes were examined According to the results, all the synthesized compounds inhibited AChE and BChE enzymes. When the IC50 values were compared, SH2-3 (IC50 = 5.27 ± 0.05 μM) and SH3-3 (IC50 = 12.29 ± 1.47 μM) compounds which are containing the Bu group have the best inhibition effect on the AChE enzyme and BChE enzyme, resp. In addition, the predictive properties of all compounds in terms of drug similarity were scanned using five Lipinski rules and ADME estimations In silico ADME studies play an important role in improving and predicting drug compounds In the ADME study; The absorption, distribution, metabolism, elimination, and properties of the mols. given below were theor. calculated Also, to evaluate the binding interactions between the sulfonylhydrazone compounds and enzymes, mol. docking studies were performed and the compounds with the best inhibition effect SH2-3 (for AChE enzyme) and SH3-3 (for BChE enzyme) were tested. Both in vitro and silico the results showed that two compounds could act as potent inhibitors of AChE, BChE. The results came from multiple reactions, including the reaction of 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Reference of 2-Hydroxy-4-methoxybenzaldehyde)

Reference of 2-Hydroxy-4-methoxybenzaldehydeIn 2019 ,《High in Vitro and in Vivo Tumor-Selective Novel Ruthenium(II) Complexes with 3-(2′-Benzimidazolyl)-7-fluoro-coumarin》 was published in ACS Medicinal Chemistry Letters. The article was written by Qin, Qi-Pin; Wang, Zhen-Feng; Huang, Xiao-Ling; Tan, Ming-Xiong; Shi, Bei-Bei; Liang, Hong. The article contains the following contents:

Three novel Ru(II) complexes, namely, (RuCl2[La][DMSO]2)·H2O (Ru1), (RuCl2[Lb][DMSO]2) (Ru2), and (RuCl2[Lc][DMSO]2) (Ru3), which resp. contain 3-(2′-benzimidazolyl)coumarin (La), 3-(2′-benzimidazolyl)-7-fluoro-coumarin (Lb), and 3-(2′-benzimidazolyl)-7-methoxyl-coumarin (Lc), were first designed and characterized. Ru2 showed potent antitumor activity against NCI-H460 cells (IC50 = 0.30 ± 0.02 μM) and high selectivity between NCI-H460 cancer cells and normal HL-7702 cells. Ru2 induced NCI-H460 apoptosis via telomerase inhibition, which involved DNA damage, cell-cycle distribution, and S phase-protein down-regulation. However, Ru1 did not demonstrate such effects in NCI-H460 cells, which is undoubtedly associated with the key regulatory role of the 7-fluoro substituted group in the Lb ligand of Ru2. Ru2 exhibited considerably higher anticancer efficacy (inhibition rate [IR] = 61.3%) compared with cisplatin (IR= 25.5%) in a NCI-H460 xenograft mouse model. Thus, this coumarin Ru(II) compound is a promising Ru2-targeting telomerase anticancer agent.

The article was written by Park, Young Ki; Oh, Hyun Ju; Bae, Jong Hyuk; Lim, Jee Young; Lee, Hee Dong; Hong, Seok Il; Son, Hyun Sik; Kim, Jong H.; Lim, Seung Ju; Lee, Woosung. The article contains the following contents:

For the immediate detection of strong gaseous alkalis and acids, colorimetric textile sensors based on halochromic dyes are highly valuable for monitoring gas leakages. To date, colorimetric textile sensors for dual-gas detection have usually been fabricated by electrospinning methods. Although nanofibrous sensors have excellent pH sensitivity, they are difficult to use com. because of their low durability, low productivity, and high production costs. In this study, we introduce novel textile sensors with high pH sensitivity and durability via a facile and low-cost screen-printing method. To fabricate these textiles sensors, Dye 3 and RhYK dyes were both incorporated into a polyester fabric. The fabricated sensors exhibited high detection rates (<10 s) and distinctive color changes under alk. or acidic conditions, even at low gas concentrations Furthermore, the fabricated sensors showed an outstanding durability and reversibility after washing and drying and were confirmed to contain limited amounts of hazardous materials. Thus, our results show that the fabricated textile sensors could be used in safety apparel that changes its color in the presence of harmful gases.

Non-embryogenic, synthetic seeds were formed by encapsulating the nodal segments (NS) of Hemidesmus indicus R. Br. in calcium alginate hydrogel comprising of MS basal medium for short-term conservation. A 3% sodium aliginate (SA) with 100 mM CaCl2 was found most suitable for the preparation of isodiametrical beads. Highest shoot regrowth (84.50 ± 0.35%) was recorded when the gelling matrix, i.e. 3% SA in Murashige and Skoog (MS) basal medium was supplemented with 5.0μM 6-benzyladenine (BA) + 0.5μM indole-3-butyric acid (IBA) and inoculated onto the nutrient medium comprised of MS + 5.0μM BA gave 5.53 ± 0.096 shoots/encapsulated NS. Rooting in microshoots was obtained on the half strength liquid MS + 0.1μM IBA. Plantlets achieved from preserved synthetic seeds were acclimatized and relocated in the natural condition successfully with the immortality rate of 89.3%. During the days of acclimatization, the obtained plants were subjected for the assessment of their pigment content and biochem. assay.

In this effort we pursue the synthesis and in vitro anticancer, antibacterial and antioxidant properties of some novel benzopyrylium salts. The benzopyrylium salts were synthesized and further characterized via UV-vis, IR, 1H-NMR, 13C-NMR and mass spectrometry. The benzopyrylium salts were tested in vitro for anticancer activity across NCI 60 cell line panel. PS-CP-4MO showed the best activity against the MDA-MB-435 cell line of melanoma cancer in terms of the least GI50 (1.78μM), TGI (3.47μM) and LC50 (6.77μM) values and showed selectivity against melanoma, colon cancer and leukemia. Mechanistic studies indicate that this compound inhibits MCF-7 cancer cells by inducing apoptosis and abrogates colony formation and wound healing in the cancer cells. Antibacterial studies show that some of the benzopyrylium salts are active on S. aureus (ATCC 29213) and the best active compound PS-CP-5Cl has a MIC of 8μg/mL. Antioxidant studies indicate that they have good free radical scavenging properties (PS-CP-5Cl showed activity 1.48 times ascorbic acid).
