Synthesis and pharmacological study of novel pyrido-quinazolone analogues as anti-fungal, antibacterial, and anticancer agents

A versatile method for novel pyrido-quinazolones was described here and tested for anti-fungal, antibacterial, and anticancerous activities. These synthesized compounds were characterized on the basis of spectroscopic techniques and evaluated for specific radiopharmaceuticals. Preliminary radiolabeling results with 99mTc and biological evaluation studies showed promising results for further evaluation in vivo. The efficiency of labeling was more than 98% and complexes were stable for about 18 h at 25 °C in the presence of serum.
