N-(2-Alkoxycarbonylbenzenesulfenyl)benzimidazoles as Nitrogen-, Sulfur-, and Carbon-Sulfenylation Reagents
摘要:
N-(2-Alkoxycarbonylbenzenesulfenyl)benzimidazoles reacted with nucleophiles such as amides, imidates, thiols, Grignard reagents, and active methylene compounds to yield the corresponding sulfenylated products: N-acylsulfenamides, N-sulfenylimidates, disulfides, sulfides, and sulfenylated active methylene compounds, respectively.
The synthesis and reaction of N-sulfenyl heterocycles: development of effective sulfenylating reagents
摘要:
Various N-sulfenyl heterocycles were synthesized by transamination of sulfenamides using a chlorine gas-free method. The N-sulfenyl heterocycles behaved as sulfenylating reagents of anilines; N-sulfenylbenzimidazoles were the most effective. (c) 2005 Elsevier Ltd. All rights reserved.
Abstract A small library of unsymmetrical cysteine disulfides as four aliphatic, three aromatic and one heteroaromatic were evaluated for their inhibition of two important carbonic anhydrase (CA) enzymes, namely human carbonic anhydrase isoenzymes I (hCA I) and II (hCA II). IC50 values were recorded in the low nanomolar range (8.6–18.3 nM for hCA I and 42.9–99.9 nM for hCA II). The inhibition activities
摘要 评估了作为四种脂肪族、三种芳香族和一种杂芳香族的不对称半胱氨酸二硫化物的小型文库对两种重要碳酸酐酶 (CA) 的抑制作用,即人类碳酸酐酶同工酶 I (hCA I) 和 II (hCA II)。IC 50值记录在低纳摩尔范围内(hCA I 为 8.6-18.3 nM,hCA II 为 42.9-99.9 nM)。抑制活性显着优于临床可用的 CA 抑制剂乙酰唑胺对 hCA I 的抑制活性,而对 hCA II 仅稍差。这些结果强调了筛选小分子作为潜在 CA 抑制剂 (CAIs) 的相关性。
