The efforts described in this article are aimed at designing organotin polymers that control the growth of breast cancer and to identify structure/property relationships that assist in this goal. The growth of MCF-7 and MDA-MB-231 breast cancer cell lines is inhibited employing a wide range of organotin condensation polymers. The EC50 values are primarily dependent on the nature of the Lewis base but the CI50 is dependent on both the nature of the Lewis base and Lewis acid. A number of products ...

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 involves the evaluation of the cellular effects when dim...

Polyether esters were rapidly formed employing the interfacial condensation of Group VA triphenylmetal dihalides with glycyrrhetinic acid in moderate yield and chain length. Infrared spectroscopy shows the formation of metal–oxygen bonds. The products are a mixture of bridging and non-bridging structures about the metal atom. Proton NMR and MALDI MS results are consistent with the formation of the polyether esters. Some of the polymers exhibit inhibition of the growth of pancreatic cancer cell l...

Organotin polyethers are easily synthesized employing interfacial polymerization systems involving the reaction of hydroxyl-containing Lewis bases and organotin halides. A wide variety of organotin-containing polymeric products have been synthesized including those derived from natural and synthetic polymers such as lignin, xylan, cellulose, dextran, and poly(vinyl alcohol). Others have been synthesized employing known drug diols such as dicumarol, DES, and dienestrol and a wide variety of synth...

Organotin polyethers containing the synthetic estrogen diethylstilbestrol have been made in moderate yield with chain lengths ranging from 20 to 200 repeat units employing the interfacial polycondensation procedure. Infrared spectroscopy shows the absence of the O–H group and formation of the Sn–O linkage consistent with the formation of the polyether. F-MALDI MS results are consistent with the presence of organotin-containing fragmentation clusters containing one and two tin atoms and ion fragm...

The current efforts described in this paper are aimed at developing compounds that inhibit the growth of prostate cancer and to identify structure/property relationships that will further assist us towards this goal. The growth of prostate cancer is affected employing a wide range of organotin condensation polymers.

A series of organotin poly(ethylene glycols) were synthesized including the first water soluble organotin polymers. These products are all polymeric with weight average molecular weights about 105. Infrared spectroscopy shows the presence of moieties from both reactants and the formation of the Sn–O linkage. F MALDI MS shows the presence of up to over a hundred units and by isotopic abundance the presence of one, two, and three tin-containing ion fragments. The polymers inhibit the growth of can...
