Quinazolines are a big family of heterocyclic compounds with anti-cancer properties.Cytotoxicity assays were performed for all compounds against different cell lines such as Human colon carcinoma (HCT116), Human chronic myeloid leukemia (K562) and Human breast cancer (SKBR3) cell lines using 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyl tetrazolium Bromide (MTT), Trypan blue and Lactose dehydrogenase release assay. The selected compounds were evaluated for their anti-tumor and anti-angiogenic effect on EAC tumor model. The molecular docking studies were drawn using maestro 2D sketcher and energy minimize was compounded by OPLS 2005.

The current study focused on balancing potency and selectivity with metabolic stability through structural modification to the metabolized site on the quinazoline core. The performed extensive structure-activity and structure-property relationship studies on this quinazoline ATM kinase inhibitor in order to identify structural variants with enhanced selectivity and metabolic stability. It shows that, while the C-7-methoxy group is essential for potency, replacing the C-6-methoxy group considerably improves metabolic stability without affecting potency. Promising analogues 20, 27g, and 27n were selected based on in vitro pharmacology and evaluated in murine pharmacokinetic and tolerability studies. Compound 27g possessed significantly improve pharmacokinetics relative to that of 4. Compound 27g was also significantly more selective against other kinases than 4. Therefore, 27g is a good candidate for further development as a potential radiosensitizer.
