Kinase Inhibitor Indole Derivatives as Anticancer Agents: A Patent Review.

Cancer accounts for a number of deaths each year. Consequently, prevention of this deadly disease is more challenging and hence the invention of new anticancer agents is of utmost importance. The current review elaborates the importance of indole designs as patented in the form of anticancer druglike molecules targeting different cites of biological arena. Specific attention was given to kinases such as platelet-derived growth factor receptor, vascular endothelial growth factor receptor and fibroblast growth factor receptor, Bruton's tyrosine kinase, anaplastic lymphoma kinase, Janus kinase, cyclin-dependent kinase aurora kinases A, B and C, checkpoint kinases, protein kinase R, Pim kinases, phosphoinositide 3- kinase, altered proteins kinases, polo-like kinase and many more. Moreover, the article summarizes the mode of action through the particular functions of kinases and the inhibitory potential of indole derivatives toward specific kinase. Certain patents gathered in the existing review article suggest that indole core can be a versatile foundation to discover drug-like kinase inhibitor molecules and modification of substituents existing on the indole moiety may have important impact on the pharmacokinetic and pharmacodynamics aspects of the resultant scaffolds. The information presented here would gather a great deal of interest to identify the new molecular designs bearing indole nucleus presenting novel anticancer drugs with a wide variety of biological targets involved in cancer pathology focusing on the inhibition of tyrosine kinases, serine/threonine-specific protein kinases, cyclin-dependent kinases, lipid kinases and altered protein kinases.
