A ring-expanded bryostatin analogue was synthesized by utilizing a Ru-catalyzed tandem tetrahydropyran formation, a Pd-catalyzed tandem dihydropyran formation, and a ring-closing metathesis (RCM) as key steps. The analogue possesses potent antitumor activity against the NCI-ADR cancer cell line with an IC50 of 123 nM.
通过利用 Ru 催化的串联四氢吡喃形成、Pd 催化的串联二氢吡喃形成和闭环复分解 (RCM) 作为关键步骤合成了扩环苔藓抑素类似物。该类似物对 NCI-ADR 癌细胞系具有有效的抗肿瘤活性,IC50 为 123 nM。
