Analogs of biologically active compounds IX. Synthesis of several new uracil and pteridine 6-aza-analogs based on cyclization of arylhydrazones derived from mesoxalic acid
摘要:
A series of 5C and 5N substituted 3-oxo-2-phenyl-1,2,4-triazine-6-carbonitriles and 8-imino-2-arylpyrimido[4,5-e][1,2,4] triazine-3,6(2H, 5H)-diones (6-aryl-6-azapteridines) are described via a cyclocondensation reaction from the corresponding aryliminohydrazones with CDI. The required aryliminohydrazones were obtained from the starting compound - malononitrile. These prepared compounds were tested for cytotoxic activity on cancer cell lines.

electron-withdrawing functions. The replacement of the fused benzene ring in the benzimidazolyl substituent by a pyrimidine ring containing the nitrogen atoms in appropriate positions causes a considerable increase in the electron-withdrawing capacity of the heterocycle. Spectroscopic and reactivity data confirm the strong electron-withdrawing nature of the purinyl ring. The (13)C NMR spectrum shows the existence
