(±) Commiphorane C, (±) commiphorane D, and their two isomers were synthesized through a linear synthesis strategy in 14 steps. Key features of the strategy include the construction of the relative configurations of C-5 and C-6 via aldehyde crotylation followed by the Mitsunobu reaction and ring A via an intramolecular Aldol reaction. The biological evaluation revealed that (±) commiphorane C and (±)
(±) Commiphorane C、(±) Commiphorane D 及其两种异构体通过线性合成策略分 14 步合成。该策略的关键特征包括通过醛
巴豆基化随后的 Mitsunobu 反应和通过分子内 Aldol 反应构建环 A的 C-5 和 C-6 的相对构型。
生物学评估表明,(±) commiphorane C 和 (±) isomer-1 显着减弱了 TGF-β1 诱导的大鼠肾近端肾小管细胞中纤连蛋白、
胶原蛋白 I 和 α-SMA 的过量产生。中间体 (±) 11显着降低
胶原蛋白 I 的过表达。细胞毒性研究表明,1a-1d和 (±) 11对 NRK-52E 细胞没有毒性。
