Synthesis, anticancer activity, and mechanistic investigations of aryl-alkyl diorganotin arylformylhydrazone complexes
Diorganotin acylhydrazone complexes with mitochondrial targeting demonstrate significant potential as replacements for platinum-based complexes due to their potent anticancer properties. Twelve methylphenyltin arylformylhydrazone complexes have been synthesized by microwave “one-pot” reaction. The complexes have been characterized by FT-IR, multinuclear NMR ( 1 H, 13 C, and 119 Sn), TGA, and HRMS. Crystal structures were determined for 10 out of the 12 complexes under study. Structures 1 through 8 , 10 and 12 possessed a central symmetric structure of a di-nuclear Sn 2 O 2 tetrahedral ring. All complexes were tested for their inhibitory activity against human cell lines NCI-H460, MCF-7, and HepG2. Complex 8 exhibited the most effective inhibitory effect on HepG2 cells, with an IC 50 value of 1.34 ± 0.04 μM. Preliminary studies on the anticancer mechanism suggest that complex 8 induces apoptosis in HepG2 cells via the mitochondrial pathway, accompanied by G2/M phase cell cycle arrest.
