Abstract Dibenzyltin(IV)dichloride and dibenzyltin(IV)diisothiocyanate derivatives with N,S-donor ligands show significant cytotoxic activities against human cancer cell lines, and are well compared to analogous dialkyltin(IV) derivatives. CoMFA models were generated for the first time for these organotin derivatives using the cytotoxic activities (against two human tumor cell lines, MCF-7, a mammary carcinoma and WiDr, a colon carcinoma) of 21 complexes. High r 2 and r 2 cv values for both CoMF...

N-Bromosuccinimide reacts with aromatic aldehydes in the solid state to yield exclusively nuclear brominated products while a similar reaction in the solution phase produces a number of products under varied conditions. The reactivity and regioselectivity have been studied in terms of the energies of HOMO, HOMO–LUMO difference, reaction free energy, reaction conditions and crystal packing. Single crystal X-ray structural analysis of 3,4-dihydroxybenzaldehyde has been carried out. Crystal packing...

In vitro effects of six dibenzyltin dichloride (A-series) and another six dibenzyltin diisothiocyanate (Bseries) complexes on Na 1 /K 1 -ATPase were studied. The rat brain synaptic membranes were prepared and significant ATPase inhibition was observed with all the complexes in a dose-dependent manner. The order of potency on Na 1 /K 1 -ATPase activity of the chloride complexes was found to be higher than that of the isothiocyanate complexes. The ic50 values range from 64 mM to 252 mM for the chl...
