Influence of DMSO on the inhibition of various cancer cells by water-soluble organotin polyethers

The effect of solvent on the ability to inhibit a group of cell lines was studied employing a series of water-soluble dibutyltin polyethers derived from various hydroxyl-terminated poly(ethylene glycols). Molecular weight as a function of time was essentially unchanged for a period of 30 weeks for the polyethers. Variations in test media can affect biological activities on the cell level as well as at the molecular level. The current study...
