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 (H, C, and 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 SnO 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 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.

Many diorganotin complexes with various alkyl groups exhibit excellent in vitro anticancer activity. However, most diorganotin is the same alkyl group, and the asymmetric alkyl R group has been rarely reported. Hence, in this paper, twenty butylphenyl mixed dialkyltin arylformylhydrazone complexes have been synthesized by microwave "one-pot" reaction with arylformylhydrazine, substituted α-keto acid or its sodium salt and butylphenyltin dichloride.

Six aroylhydrazone di-m-chlorobenzyltin complexes {[X-CH(O)C=N-N=C(Me)COO](MeOH)(m-Cl-CHCH)Sn} (X = p-Me- (1), p-MeO- (2), p-t-Bu- (3), p-NO- (4), p-OH- (5) or o-OH- (6)) were synthesized and characterized by HRMS (high-resolution mass spectrometry), NMR (nuclear magnetic resonance spectroscopy), IR (Fourier transform infrared spectroscopy), and TGA (thermogravimetric analysis) techniques. The molecular structure of complexes 1-6 was confirmed by single-crystal X-ray crystallography. The structure of complexes showed a distorted pentagonal bipyramidal configuration around the tin atom center, and the ligands adopted a tridentate chelating mode.

Fourteen new organotin(IV) complexes were successfully synthesized and characterized by elemental analyses, Fourier transform infrared spectroscopy (FT-IR), multinuclear (1H, 13C, and 119Sn) NMR spectroscopy, high-resolution mass spectrometry (HRMS), and X-ray single-crystal techniques. Crystallographic data showed that the complexes 1b, 2b, 3b, and 5b were macrocyclic compounds, 4b exhibited a one-dimensional spiral chain structure with distorted trigonal bipyramidal geometry, other complexes were centrosymmetric dimers, and there was an Sn2O2 four-membered ring in the middle of the molecule. In-vitro anticancer activity against the three human tumor cell lines NCI-H460, MCF-7, and HepG2 was studied, and the dibutyltin complex 5a is a more potent antitumor agent than other complexes and cisplatin.
