SB87-Cl 1, an inhibitor of testosterone-5α-reductase, and pestalone 2 exhibiting effective antimicrobial activity against MRSA (MIC = 37 ng/mL) and VRE (MIC = 78 ng/mL), were novel bioactive benzophenone natural products. Total synthesis of 1 and 2 has been successfully accomplished. The common synthetic precursor 18 of 1 and 2, was successfully obtained by the coupling of 8 with 12.
SB87-Cl 1(一种睾丸激素5α-还原酶的抑制剂)和pastealone 2对MRSA(MIC = 37 ng / mL)和VRE(MIC = 78 ng / mL)表现出有效的抗菌活性,是新型的生物活性二苯甲酮天然产物。1和2的总合成已成功完成。共用合成前体18的1和2,已成功的偶联获得8与12。
