Chemistry and Pharmacology
A comparative biochemical study of four Group IV element compounds with specific sulphur-containing organic substrates has been carried out and discussed. The structural characterizations of these organometallics, viz. Me2SiLCl, Me2SiL2, Me3SiL, Ph2SiLCl, Ph2SiL2, Ph3SiL, Ph3GeL, Cp2TiLCl, Cp2TiL2, Cp2ZrLCl and Cp2ZrL2 (where LH=2-acetylthiophene thiosemicarbazone) had been deduced on the basis of various physico-chemical and instrumental techniques, viz., IR, UV, 1H NMR, 13C NMR AND 29SI NMR spectral studies. All the organometallics and the parent thiomine have been screened against a number of microbes and their sterilizing power in male mice tested. The results of these biocidal studies show that the organosilicon(IV) and organogermanium(IV) compounds are more active than the organotitanium(IV) and organozirconium(IV) derivatives. An attempt has also been made to correlate the structural aspects of the molecule with its biological activity.
