series of new nalidixic acidderivatives having quinazolones moiety were synthesised to achieve enhanced biological activity and wide spectrum of activity. Nalidixic acid was first converted into its acid chloride using thionyl chloride as an acylating agent at laboratory temperature. Later it was converted to methylester. Nalidixoyl chloride formed vigorously reacts with methanol to give a methyl ester

A series of disubstituted-quinazolin-4(3H)-ones derivatives have been synthesized and confirmed through IR, 1H- and 13C-NMR, MS spectroscopy and elemental analysis. Synthesized compounds were screened for in vitro and in vivo anti-inflammatory using human red blood cell membrane stabilization method and carrageenan-induced rat paw edema. The antimicrobial potency was measured by disk diffusion method
Disclosed are 4-arylamino-quinazolines and analogs thereof effective as activators of caspases and inducers of apoptosis. The compounds of this invention are useful in the treatment of a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
