Molecular Modelling and Synthesis of Certain Heterocyclic Compounds with Expected Biological Activity

Abstract

Cancer, also known as a malignant tumor, is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. A major problem in treating cancer is the fact that it is not a single disease. There are more than 200 different cancers resulting from different cellular defects. The growth of new blood vessels (angiogenesis) is one of the well established hallmarks in the process of carcinogenesis. Vascular endothelial growth factor receptor-2 (VEGFR-2) plays a crucial role in cancer angiogenesis. By targeting VEGFR-2, angiogenesis is greatly inhibited leading to the death of the tumor cells. In this study, thienopyrimidine derivatives have been designed and synthesized as targeted angiogenesis inhibitors. The design focused on exploration of the previous revealed SAR studies, bioisosteric modifications of the lead compounds both in market and in clinical studies, and identification of the key interactions with the binding site in silico. Synthesis of the designed compounds was then accomplished & their structures were confirmed by various spectral and microanalytical data.
