Synthesis and antimalarial activity of 94 novel bipyrrole tambjamines (TAs) and a library of B-ring functionalized tripyrrole prodiginines (PGs) against a panel of Plasmodium falciparum strains are described. The activity and structure–activity relationships demonstrate that the ring-C of PGs can be replaced by an alkylamine, providing for TAs with retained/enhanced potency. Furthermore, ring-B of

series of adamantoyl L-prolinamides have been synthesized. These compounds have been found to be highly efficient organocatalysts for the Michaeladdition of aldehydes and ketones to nitroalkenes. Under the optimized reaction conditions, the corresponding Michael adducts were obtained in good yields (up to 95%), excellent enantioselectivities (up to 99% ee) and moderate diastereoselectivities.
community-acquired infections, with drug-resistant strains being responsible for tens of thousands of deaths per year. S. aureus sortase A inhibitors are designed to interfere with virulence determinants. We have identified disulfanylbenzamides as a new class of potent inhibitors against sortase A that act by covalent modification of the active-site cysteine. A broad series of derivatives were synthesized to
金黄色葡萄球菌是医院和社区获得性感染的最常见原因之一,耐药菌株每年导致数万人死亡。金黄色葡萄球菌分选酶 A 抑制剂旨在干扰毒力决定因素。我们已经确定二硫烷基苯甲酰胺是一类新型有效的分选酶 A 抑制剂,通过活性位点半胱氨酸的共价修饰发挥作用。合成了一系列广泛的衍生物来推导构效关系(SAR)。体外和计算机方法使实验观察到的结合亲和力和选择性合理化。研究发现,最活跃的化合物具有个位数的微摩尔 Ki 值,在 10 μM 的有效抑制剂浓度下,金黄色葡萄球菌纤维蛋白原附着量减少高达 66%。这种新分子类别表现出最小的细胞毒性、较低的细菌生长抑制和分选酶介导的金黄色葡萄球菌细胞粘附受损。
