Previously we discovered a tricyclic indoline, N-[2-(6-bromo-4-methylidene-2,3,4,4a,9,9a-hexahydro-1H-carbazol-4a-yl)ethyl]-4-chlorobenzene-1-sulfonamide (1, Of1), from bioinspired synthesis of a highly diverse polycyclic indoline alkaloid library, that selectively resensitizes methicillin-resistant Staphylococcus aureus strains to β-lactam antibiotics. Herein, we report a thorough structure–activity
之前我们发现了一种三环二氢吲哚,N -[2-(6-bromo-4-methylidene-2,3,4,4a,9,9a-hexahydro-1 H -carbazol-4a-yl)ethyl]-4-chlorobenzo -1-磺酰胺 ( 1 , Of1),来自高度多样化的多环二氢吲哚生物碱库的生物启发合成,可选择性地使耐甲氧西林金黄色葡萄球菌菌株对 β-内酰胺抗生素重新敏感。在此,我们报告了对1的彻底构效关系研究,该研究确定了1 的区域可以耐受修饰而不影响活性,并发现了一种更有效的具有降低哺乳动物毒性的类似物。
