Photoswitchable lipids are attached to a lipidated natural product, the potent proteasome inhibitor cepafungin I. The lead-compound PhotoCep4 exhibited a 10-fold higher cellular potency in its light-induced cis-form, matching the potency and proteome-wide modulation of constitutively active cepafungin I. This approach could be applicable to many other natural products as lipid conjugation is common
光开关脂质附着在脂质化的天然产物上,即有效的蛋白酶体抑制剂头孢芬净 I。铅化合物 PhotoCep4 在其光诱导的顺式形式中表现出 10 倍的细胞效力,与组成型活性头孢芬净 I 的效力和蛋白质组范围调节相匹配。这种方法可能适用于许多其他天然产物,因为脂质偶联很常见,并且通常是有效活性所必需的。
