Facile transformation of Biginelli pyrimidin-2(1H)-ones to pyrimidines. In vitro evaluation as inhibitors of Mycobacterium tuberculosis and modulators of cytostatic activity

A series of pyrimidine derivatives bearing amine substituents at C-2 position were obtained from Biginelli 3,4-dihydropyrimidin-2(1H)-ones and the effect of structural variation on anti-TB activity against Mycobacterium tuberculosis H(37)Rv strain and antiviral activity in a series of cell cultures was evaluated. While the compounds were found to possess structure dependent cytostatic activity, these were not found to be efficient inhibitors of M. tuberculosis nor did they inhibit a broad variety of DNA or RNA viruses in cell culture.
