To investigate the impact of introducing a trans-double bond on the anticancer activity of harmine, nineteen novel harmine derivatives substituted with a trans-double bond at the 6-position were designed and synthesized. Their inhibitory activities against A549, HepG2, and MDA-MB-231 cell lines were then evaluated. The results indicated that the majority of the derivatives exhibited higher activities than the parent compound harmine. Among these derivatives, compound 4i demonstrated the most potent anti-proliferative activity, with an IC50 value of 1.67 μM against MDA-MB-231 cells. Further mechanistic studies revealed that this compound could induce apoptosis in a concentration-dependent manner and arrest the cell cycle of MDA-MB-231 at the G2/M phase. Furthermore, molecular docking studies indicated that compound 4i exhibited a strong binding affinity to the EGFR active site through hydrogen bonding, hydrophobic interactions, and π-π stacking. RT-qPCR analysis of the key genes in the downstream signaling pathway of EGFR kinase suggested that 4i might indeed serve as an EGFR inhibitor. Notably, compound 4i exhibited favorable selectivity (SI=3.06) between normal lung epithelial cells BEAS-2B and cancer cells MDA-MB-231, highlighting its potential for further investigation.
