Choi, Hosam;Choi, Joohee;Han, Jongyeol;Lee, Kiyoun research published 《 Divergent Total Syntheses of Gymnothelignan N, Beilschmin A, and Eupomatilones 1, 3, 4, and 7》, the research content is summarized as follows. A seven-step asym. total synthesis of gymnothelignan N is detailed in the current report. The approach is based on an early-stage one-carbon homologative lactonization reaction, which we recently revisited and modified to construct the core γ-butyrolactone motif with the requisite β,γ-vicinal stereogenic centers. By design, the utilization of the same chiral γ-butyrolactone intermediate permitted the rapid and effective divergent assembly of optically active eupomatilones 1, 3, 4, and 7 in five or six steps from com. available materials. This represents one of the shortest and highest-yielding syntheses reported to date.

A novel series of compounds such as I [R = CH₂NHCHCO₂HCH₂OH, CH₂(N-piperidin-3-ol), CH₂(N-pyrrolidin-3-ol), etc.] bearing a benzo[d]isothiazole scaffold were developed, among which compound I [R = CH₂NHCHCO₂HCH₂OH] exhibited promising activity, with an IC₅₀ value of 8.5 nM. Further cell-based PD-1/PD-L1 blockade bioassays indicated that compound I [R = CH₂NHCHCO₂HCH₂OH] could inhibit the PD-1/PD-L1 interaction at the cellular level, with an EC₅₀ value of 5.6μM compound I [R = CH₂NHCHCO₂HCH₂OH] could had better potency in restoring the activity of effector cells, as the maximal luminescence values (RLUmax) of compound I [R = CH₂NHCHCO₂HCH₂OH] were equivalent to those of PD-L1 mAbs. The docking anal. of compound I [R = CH₂NHCHCO₂HCH₂OH] with the PD-L1 dimer complex (PDB ID: 6R3K) confirmed that I [R = CH₂NHCHCO₂HCH₂OH] was a promising lead compound for the development of inhibitors of the PD-1/PD-L1 interaction. The preliminary structure-activity relationship was investigated in this paper, with the aim of future drug development.

Chen, Wang;Feng, Zili;Hu, Daihua;Meng, Jin research published 《 Design and Synthesis of Arylnaphthalene Lignan Lactone Derivatives as Potent Topoisomerase Inhibitors》, the research content is summarized as follows. Arylnaphthalene lignan lactones are a class of natural products containing the phenyl-naphthyl skeleton. Some arylnaphthalene lignan lactones have been used in clin. practice as antitumor agents, due to their cytotoxicity and inhibitory activities against DNA topoisomerase I (Topo I) and topoisomerase II (Topo II). This study presents the design and synthesis of arylnaphthalene lignan lactones derivatives The inhibitory activities against Topo I and Topo IIα and antitumor activities of these compounds were assayed. A series of arylnaphthalene lignan lactones derivatives have been designed and synthesized, using the Diels-Alder reaction and Suzuki reaction as the key steps. Their antiproliferation activities were evaluated by sulforhodamine B assay on human breast cancer MDAMB-231, MDA-MB-435 and human cervical cancer HeLa cells. DNA relaxation assays were employed to examine the inhibitory activity of compounds 1-22 on Topo I and Topo IIα in vitro. Flow cytometry anal. was performed to study the drug effects on cell cycle progressions. Seven compounds exhibited the modest anti-proliferation activity with IC₅₀ values between 1.36 and 20 μM. Compounds 3, 19 and 22 showed potent inhibitory activities with IC₅₀ values less than 1 μM. DNA relaxation assay revealed that compound 22 showed potent inhibitory activity against Topo IIα in vitro. Compound 22 also induced DNA breaks in MDA-MB-435 cells evidenced by comet tails and the accumulation of γ-H2AX foci. The ability of 22 in inducing DNA breaks mediated by Topo IIα resulted in G2/M phase arrest and apoptosis. This work indicates that arylnaphthalene lignan lactones derivatives represent a novel type of Topo IIα inhibitory scaffold for developing new antitumor chemotherapeutic agents.

Allylic arylation of α-fluoro but-1-enoic acid amides with arylboronic acids was carried out in water by comparing the catalytic activity of iridium(III) and rhodium(III). Ir(III) has shown a strong superiority over Rh(III) to give allyl-aryl coupling products with excellent stereoselectivity in favor of the Z-isomer. The origin of high stereoselectivity is perhaps because of the a coordination of iridium Ir-N or Ir-O.

Tryptophan hydroxylase 1 (TPH1) has been recently suggested as a promising therapeutic target for treating obesity and fatty liver disease. A new series of 1,2,4-oxadiazolylphenyl alanine derivatives were identified as TPH1 inhibitors. Among them, compound 23a was the most active in vitro, with an IC₅₀ (half-maximal inhibitory concentration) value of 42 nM, showed good liver microsomal stability, and showed no significant inhibition of CYP and hERG. Compound 23a inhibited TPH1 in the peripheral tissue with limited BBB penetration. In high-fat diet-fed mice, 23a reduced body weight gain, body fat, and hepatic lipid accumulation. Also, 23a improved glucose intolerance and energy expenditure. Taken together, compound 23a shows promise as a therapeutic agent for the treatment of obesity and fatty liver diseases.

Bezzu, C. Grazia;Fuoco, Alessio;Esposito, Elisa;Monteleone, Marcello;Longo, Mariagiulia;Jansen, Johannes Carolus;Nichol, Gary S.;McKeown, Neil B. research published 《 Ultrapermeable Polymers of Intrinsic Microporosity (PIMs) Containing Spirocyclic Units with Fused Triptycenes》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs), such as the archetypal spirobisindane-based PIM-1, are among the most promising new materials for making gas separation membranes with high permeance for potential use in high-throughput applications. Here it is shown that ultrapermeable PIMs can be prepared by fusing rigid and bulky triptycene (Trip) to the spirobisindane (SBI) unit. PIM-SBI-Trip and its copolymer with PIM-1 (PIM-1/SBI-Trip) are both ultrapermeable after methanol treatment (P_CO2 > 20 000 Barrer). Old films, although less permeable, are more selective and therefore provide data that are close to the recently redefined Robeson upper bounds for the important CO₂/CH₄, CO₂/N₂, and O₂/N₂ gas pairs. Temperature-dependent permeation measurements and anal. of the entropic and energetic contributions of the gas transport parameters show that the enhanced performance of these polymers is governed by strong size-sieving character, mainly due to the energetic term of the diffusivity, and related to their high rigidity. Both polymers show a relatively weak pressure-dependence in mixed gas permeability experiments up to 6 bar, suggesting a potential use for CO₂ capture from flue gas or for the upgrading of biogas.
