Among the hapalosin derivatives synthesized, the compounds carrying methyl (5a), methylthioethyl (5d) and phenylmethyl (5e) groups at the C12 position possess only the cis-peptide structure, in contrast to the cases of 5b and 5c. In addition to their conformational stability, the biological activities of the compounds were determined in relation of the P-glycoprotein-mediated MDR-reversing activity
与5b和5c的情况相反,在合成的Hapalosin衍生物中,在C12位置带有甲基(5a),甲硫基乙基(5d)和苯基甲基(5e)的化合物仅具有顺肽结构。除了它们的构象稳定性之外,还根据P-糖蛋白介导的MDR-逆转活性和细胞凋亡的诱导来确定化合物的生物学活性。
