It develops when normal cells begin to grow out of control in particular part of the body. Cancer is a leading cause of death worldwide, accounting for 8.8 million deaths in 2015. According to WHO, the most common causes of cancer death are cancers of Lung (1.69 million deaths), Liver (788 000 deaths), Colorectal (774 000 deaths), Stomach (754 000 deaths) and Breast (571 000 deaths). PARP-1 is a ubiquitous zincfinger DNA-binding enzyme that is activated by binding to DNA breaks and then catalyzes the synthesis of the branched polymer PAR using NAD+ as the building block. PARP-1 has a crucial role in cell proliferation, survival, and death, due to its properties on regulation of multiple biological processes. Quinazolinone and its derivatives possess a large class of biologically active compounds that exhibited broad spectrum of biological activities such as anti-HIV, anticancer, antifungal, antibacterial, anticonvulsant, anti-inflammatory, antidepressant, antimalarial, antioxidant, antileukemic, and antileishmanial activities and other activities. In this study, we have synthesized quinazolinone derivatives and studied the in silico properties as PARP-1 inhibitors which indicated that quinazolinone derivatives were having good affinity towards active site of PARP-1. Out of all synthesized compounds, SVA-11 was having maximum dock score (-10.421).en-USCancerPARP-1QuinazolinoneMaster DissertationT00752
