Abstract
Fourteen glaucocalyxin A biotinylated derivatives, one glaucocalyxin C biotinylated derivative, and two oridonin biotinylated derivatives were designed and synthesized. Their structures were confirmed from 1H NMR, 13C NMR and HRMS data. The derivatives were evaluated for cytotoxic activities against lung (A549), cervical cancer cell line HeLa derivative (KB), multidrug-resistant KB subline (KB-VIN), triple-negative breast (MDA-MB-231), and estrogen receptor-positive breast (MCF-7) cancer cell lines.
