We previously developed a dithienylcyclopentene dopant that bears two methylenedioxy-bridged binaphthyl moieties. Herein, we report our new findings on related compounds that entail different bridge lengths in their binaphthyl units. Three new compounds were synthesized. It was found that variations of the bridge length resulted in significantly different photoresponsive properties in LC media.

Kong, Deyu published the artcileOptimization of P2Y₁₂ Antagonist Ethyl 6-(4-((Benzylsulfonyl)carbamoyl)piperidin-1-yl)-5-cyano-2-methylnicotinate (AZD1283) Led to the Discovery of an Oral Antiplatelet Agent with Improved Druglike Properties, Synthetic Route of 939-99-1, the publication is Journal of Medicinal Chemistry (2019), 62(6), 3088-3106, database is CAplus and MEDLINE.

P2Y₁₂ antagonists are widely used as antiplatelet agents for the prevention and treatment of arterial thrombosis. Based on the scaffold of a known P2Y₁₂ antagonist AZD1283 (I), a series of novel bicyclic pyridine derivatives were designed and synthesized. The cyclization of the ester substituent on the pyridine ring to the ortho-Me group led to lactone analogs of AZD1283 that showed significantly enhanced metabolic stability in subsequent structure-pharmacokinetic relationship studies. The metabolic stability was further enhanced by adding a 4-Me substituent to the piperidinyl moiety. Compound II displayed potent inhibition of platelet aggregation in vitro as well as antithrombotic efficacy in a rat ferric chloride model. Moreover, II showed a safety profile that was superior to what was observed for clopidogrel in a rat tail-bleeding model. These results support the further evaluation of compound II as a promising drug candidate.

Narjes, Frank published the artcilePotent and Orally Bioavailable Inverse Agonists of RORγt Resulting from Structure-Based Design, COA of Formula: C7H5BClNO2, the publication is Journal of Medicinal Chemistry (2018), 61(17), 7796-7813, database is CAplus and MEDLINE.

Retinoic acid receptor related orphan receptor γt (RORγt), has been identified as the master regulator of T_H17-cell function and development, making it an attractive target for the treatment of autoimmune diseases by a small-mol. approach. Herein, we describe our investigations on a series of 4-aryl-thienyl acetamides, which were guided by insights from X-ray cocrystal structures. Efforts in targeting the cofactor-recruitment site from the 4-aryl group on the thiophene led to a series of potent binders with nanomolar activity in a primary human-T_H17-cell assay. The observation of a DMSO mol. binding in a subpocket outside the LBD inspired the introduction of an acetamide into the benzylic position of these compounds Hereby, a hydrogen-bond interaction of the introduced acetamide oxygen with the backbone amide of Glu379 was established. This greatly enhanced the cellular activity of previously weakly cell-active compounds The best compounds combined potent inhibition of IL-17 release with favorable PK in rodents, with compound 32 representing a promising starting point for future investigations.

Matralis, Alexios N. published the artcileMolecular tools that block maturation of the nuclear lamin A and decelerate cancer cell migration, Related Products of chlorides-buliding-blocks, the publication is Bioorganic & Medicinal Chemistry (2018), 26(20), 5547-5554, database is CAplus and MEDLINE.

Lamin A contributes to the structure of nuclei in all mammalian cells and plays an important role in cell division and migration. Mature lamin A is derived from a farnesylated precursor protein, known as prelamin A, which undergoes posttranslational cleavage catalyzed by the zinc metalloprotease STE24 (ZPMSTE24). Accumulation of farnesylated prelamin A in the nuclear envelope compromises cell division, impairs mitosis and induces an increased expression of inflammatory gene products. ZMPSTE24 has been proposed as a potential therapeutic target in oncol. A library of peptidomimetic compounds were synthesized and screened for their ability to induce accumulation of prelamin A in cancer cells and block cell migration in pancreatic ductal adenocarcinoma cells. The results of this study suggest that inhibitors of lamin A maturation may interfere with cell migration, the biol. process required for cancer metastasis.

Chen, Zhifei published the artcileSynthesis of 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one from maltol and its taste identification, Application In Synthesis of 21286-54-4, the publication is Food Chemistry (2021), 130052, database is CAplus and MEDLINE.

2,3-Dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (DDMP) exists in many foods, and its effect on taste is controversial. The aim of this study was to clarify whether DDMP has bitter taste or not. For this purpose, DDMP was synthesized from maltol instead of from glucose for the first time. In contrast, DDMP derived from glucose was also prepared and further purified. Their structures were identified by NMR and MS, and considered to be the same substance. The sensory anal. showed that DDMP derived from maltol was tasteless. Further studies indicated that some impurities in Maillard reaction made DDMP derived from glucose taste bitter.
