Structure and Biological Properties of 2-Phenylhydrazone Derivatives of Thiazolopyrimidines


A number of 2-phenylhydrazone derivatives of thiazolo[3,2-a]pyrimidines has been synthesized, and their structure and biological activity have been studied. The structure of the obtained compounds has been confirmed by 1H and 13C NMR spectroscopy and X-ray diffraction analysis. It has been found that hydrazone form with Z configuration of the C=N bond is typical for the obtained derivatives. Low cytotoxicity of the synthesized compounds toward normal and tumor cell lines has been shown.
