Quaternary ammonium salts of potential biological activity

For possible antimicrobial activity, several quaternary ammonium salts were synthesized which were derived from pyrimidines and 4,7- phenanthroline 5,6-quinone

Reactions with purine derivative: synthesis of arylamino purines of antitumor effects

2,6-diamino, 3,7-dihydro, 7-methyl, [II], 6- amino,3,7- dimethyl, purine, 2-one [III], 6- amino, 3-hydro, 3-methyl, purine, [V] were obtained in one-pot reaction. The derivatives were tested for their antitumour activities
