compounds that inhibit pilus assembly in uropathogenic Escherichia coli. Their biological activity is clearly dependent upon a carboxylic acid functionality. Here, we present the synthesis and biological evaluation of carboxylic acid isosteres, including, for example, tetrazoles, acyl sulfonamides, and hydroxamic acids of two lead 2-pyridones. Two independent biological evaluations show that acyl sulfonamides
环稠合 2-吡啶酮,称为 pilicides,是一种小的合成化合物,可抑制尿路致病性大肠杆菌中的菌毛组装。它们的生物活性显然取决于羧酸官能度。在这里,我们介绍了羧酸等排体的合成和生物学评价,包括例如四唑、酰基磺酰胺和两种铅 2-吡啶酮的异羟肟酸。两项独立的生物学评估表明,酰基磺酰胺和四唑显着提高了对尿路致病性大肠杆菌的杀毛虫活性。
