Invasive and metastatic behaviours in various cancers, including hepatocellular carcinoma (HCC), are closely monitored through the use of VEGF signalling pathway inhibitors. Specifically in HCC, VEGFR-1 facilitates the invasive capabilities of cancer cells primarily by triggering the epithelial-mesenchymal transition (EMT) process. VEGFR-1 significantly influences the activity of proteolytic enzymes that are critical for the invasive behaviour of HCC cells. Notably, a novel mechanism has been discovered where VEGFR-1 activation leads to the upregulation of MMP-9, thereby enhancing the invasiveness of HCC cells. The scientists, in their study, have elaborated on the various antiangiogenic agents developed for the treatment of HCC. They have highlighted clinical trials that explore the efficacy of these treatments, which include the application of monoclonal antibodies and small-molecule kinase inhibitors designed to target specific pathways involved in tumour angiogenesis and growth.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;Creating a pharmaceutical chemistry table regarding \"Structure-Activity Relationship of New Compounds on anticancer''.
