Further optimization of the M5 NAM MLPCN probe ML375: Tactics and challenges
摘要:
This Letter describes the continued optimization of the MLPCN probe ML375, a highly selective M-5 negative allosteric modulator (NAM), through a combination of matrix libraries and iterative parallel synthesis. True to certain allosteric ligands, SAR was shallow, and the matrix library approach highlighted the challenges with M-5 NAM SAR within in this chemotype. Once again, enantiospecific activity was noted, and potency at rat and human M-5 were improved over ML375, along with slight enhancement in physiochemical properties, certain in vitro DMPK parameters and CNS distribution. Attempts to further enhance pharmacokinetics with deuterium incorporation afforded mixed results, but pretreatment with a pan-P450 inhibitor (1-aminobenzotriazole; ABT) provided increased plasma exposure.

Selective non-nucleoside HIV-1 reverse transcriptase inhibitors. New 2,3-dihydrothiazolo[2,3-a]isoindol-5(9bH)-ones and related compounds with anti-HIV-1 activity
A series of substituted 2,3-dihydrothiazolo[2,3-a]isoindol-5(9bH)-ones and related compounds 1-73 were synthesized and evaluated for their ability to inhibit reverse transcriptase (RT) of the human immune deficiency virus 1 (HIV-1) and replication of HIV-1 in MT2 cells. The antiviral activity of these compounds depends on the stereoselective configuration of the substituent in position 9b. Structure-activity

Dibenzo[b,f][1,5]diazocines are a class of eight-membered heterocycles, which exhibit unique rigid saddle-shaped structure and possess inherent chirality. In this study, we report a convenient and straightforward method for the catalytic enantioselective synthesis of these unique chiral molecules through chiral phosphoric acid-catalyzed dimerization of 2-acylbenzoisocyanates. Notably, the addition
二苯并[ b , f ][1,5]二氮杂辛是一类八元杂环化合物,具有独特的刚性鞍状结构并具有固有的手性。在这项研究中,我们报告了一种方便、直接的方法,通过手性磷酸催化 2-酰基苯并异氰酸酯的二聚,催化对映选择性合成这些独特的手性分子。值得注意的是,添加相应的2-酰基苯胺作为助催化剂显着提高了这些反应的效率,并且简单的相分离操作导致产物具有优异的对映体纯度。进行实验研究是为了阐明这些反应背后的机制,并根据研究结果提出合理的反应机制。
