A series of novel 1,2,3-triazole/isoxazole functionalized pyrido[2,3-d]pyrimidine derivatives 6a-c, 7a-h and 8a-e were prepared in series of synthetic steps. All the compounds screened for the anticancer activity against four human cancer cell lines using Nocodazole as standard. Compounds 7d and 7h showed highest activity against PANC-1 (pancreatic cancer) and A549 (lung cancer) cell lines respectively and more than standard. All the compounds also screened for antibacterial activity using Rifampicin and Ciprofloxacin as standards and identified promising compounds further evaluated for minimum inhibitory concentration to validate the data.
