  ABSTRACT: Hydrazinolysis of 6-chloro-1-methyluracil followed by condensation of the product with different aromatic aldehyde gives the respective hydrazones which undergoes oxidative cyclization using thionyl chloride to obtain pyrazolo[3,4-d]pyrimidines in good yields. On the other hand, nitrosation of 6-aminouracils followed by the reaction with different arylidineanilines gives new xanthine derivatives. Finally, indenopyrrolopyrimidine and indenopteridine are obtained in good yields via the reaction of 6-aminouracils and 5,6-diaminouracil with ninhydrin respectively. The newly synthesized compounds show binding, chelation and fragmentation of the nucleic acid DNA.
