  Pyrrolidine-3-carboxylic Acids as Endothelin Antagonists. 4. Side Chain Conformational Restriction Leads to ET_B Selectivity

  摘要：

  When the dialkylacetamide side chain of the ETA-selective antagonist ABT-627 is replaced with a 2,6-dialkylacetanilide, the resultant analogues show a complete reversal of receptor selectivity, preferring ETB over ETA. By optimizing the aniline substitution pattern, as well as the alkoxy group on the 2-aryl substituent, it is possible to prepare antagonists with subnanomolar affinity for ETB and with selectivities in excess of 4000-fold. A number of these compounds also show promising pharmacokinetic profiles; a useful balance of properties is found in A-192621 (38). Pharmacology studies with A-192621 serve to reveal the role of the ETB receptor in modulating blood pressure; the observed hypertensive response to persistent ETB blockade is consistent with previous postulates and indicates that ETB-selective antagonists may not be suitable as agents for long-term systemic therapy.

  光谱技术合成1,2,4-三唑含氮杂嗪乙酰胺衍生物及其与牛血清白蛋白的结合相互作用

  摘要：

  合成了一系列新的含1,2,4-三唑和氮杂部分的乙酰胺衍生物，并使用$ ^ {1} $ H NMR，$ ^ {13} $ C NMR，IR和EI-MS光谱分析对其进行了表征。中间体三唑是通过羧酸盐和碳酰肼的顺序合成而合成的。评价了新合成的1,2,4-三唑衍生物与牛血清白蛋白（BSA）的结合以及热力学，位点选择性结合和同步研究。通过BSA结合以及热力学研究获得的结果证明，所有化合物均显示出与BSA的自发相互作用，并且可以有效地分布并从体内清除。因此，基于三唑的类似物可能是设计新药系统的有用策略。

  The imperative demand for antibacterial agents and enzyme inhibitors prompted us to synthesize some new compounds, 6a-6k, bearing multifunctional moieties. The target acetamides were derived from 4-phenyl-5-(1-tosylpiperidin-4-yl)-4$H$-1,2,4-triazole-3-thiol (3). The structural analysis was carried out using modern spectroscopic techniques including IR, NMR, and EIMS spectral analysis. The antibacterial activity was screened against five bacterial strains including three gram-negative and two gram-positive ones. Enzyme inhibition was carried out against lipoxygenase enzyme and results were supported by in silico study. The synthesized compounds were proved to be potent antibacterial agents and enzyme inhibitors.
