  小分子CD4模拟物作为HIV进入抑制剂的灵活性

  摘要：

  CD4模拟物（例如YIR-821及其衍生物）是抑制HIV-1 gp120的Phe43腔与宿主CD4之间相互作用的小分子，这种相互作用涉及HIV进入细胞。已知的CD4模拟物通常具有三个结构特征，芳环，草酰胺键和哌啶部分。先前我们已经表明，将环己基和胍基引入哌啶部分，在间位引入氟原子芳环的-位导致抗HIV活性的显着增加。在当前的研究中，通过在草酰胺连接体和芳族部分之间的连接处引入吲哚型基团或通过用甘氨酸连接体取代草酰胺连接体来研究构象柔韧性的影响。这导致了具有高抗HIV活性的化合物的开发，显示了连接区对于高抗HIV活性表达的重要性。预期目前的数据可用于新型CD4模拟分子的未来设计。

  Indole-2-carboxamides have been identified as a promising class of antituberculosis agents from phenotypic screening against mycobacteria. One of the hits, indole-2-carboxamide analog (1), had low micromolar potency against Mycobacterium tuberculosis (Mtb), high mouse liver microsomal clearance, and low aqueous solubility. Structure activity relationship studies revealed that attaching alkyl groups to the cyclohexyl ring significantly improved Mtb activity but reduced solubility. Furthermore, chloro, fluor, or cyano substitutions on the 4- and 6-positions of the indole ring as well as methyl substitution on the cyclohexyl ring significantly improved metabolic stability. 39 and 41, the lead candidates, displayed improved in vitro activity compared to most of the current standard TB drugs. The low aqueous solubility could not be mitigated because of the positive correlation of lipophilicity with Mtb potency. However, both compounds displayed favorable oral pharmacokinetic properties in rodents and demonstrated in vivo efficacy. Thus, indole-2-carboxamides represent a promising new class of antituberculosis agents.

We have shown previously that introduction of a cyclohexyl group and a guanidine group into the piperidine moiety and a fluorine atom at the meta-position of the aromatic ring leads to a significant increase in the anti-HIV activity. In the current study, the effects of conformational flexibility were investigated by

  Tuberculosis (TB) remains one of the leading causes of mortality and morbidity worldwide, with approximately one-third of the world's population infected with latent TB. This is further aggravated by HIV coinfection and the emergence of multidrug- and extensively drug-resistant (MDR and XDR, respectively) TB; hence the quest for highly effective antitubercular drugs with novel modes of action is imperative. We report herein the discovery of an indole-2-carboxamide analogue, 3, as a highly potent antitubercular agent, and the subsequent chemical modifications aimed at establishing a preliminary body of structure activity relationships (SARs). These efforts led to the identification of three molecules (12-14) possessing an exceptional activity in the low nanomolar range against actively replicating Mycobacterium tuberculosis, with minimum inhibitory concentration (MIC) values lower than those of the most prominent antitubercular agents currently in use. These compounds were also devoid of apparent toxicity to Vero cells. Importantly, compound 12 was found to be active against the tested XDR-TB strains and orally active in the serum inhibition titration assay.
