Guided by the inhibitory activities of indole-containing natural products against isocitrate lyase (ICL) from Candida albicans and sortase A (SrtA) from Staphylococcus aureus, a series of compounds structurally analogous to natural products were synthesized. Eight SrtA inhibitors and an ICL inhibitor having higher activities than the natural products were discovered by screening the enzyme inhibitory
在含吲哚的天然产物对白色念珠菌的异柠檬酸裂合酶(ICL)和金黄色葡萄球菌的分选酶A(SrtA)的抑制活性的指导下,合成了一系列与天然产物结构相似的化合物。通过筛选合成化合物的酶抑制活性,发现了八种具有比天然产物更高活性的SrtA抑制剂和ICL抑制剂。在发现的SrtA抑制剂中,有六种具有比对羟基巯基苯甲酸更高的活性,这表明这些化合物具有作为替代抗菌剂的巨大潜力。
