Anticancer Potential of Piperidine Containing Small Molecule Targeted Therapeutics

In the past two decades, targeted anti‐cancer therapeutics have achieved remarkable success due to their exceptional advantages of selectivity towards cancer cells and safety. Targeted small molecule anti‐cancer therapies persisted in many barriers; majorly poor response to drug therapy. Piperidine, a heterocyclic moiety, exceeds twenty instances of other pharmaceutical classes and natural compounds in the form of alkaloids effective in anti‐cancer treatment. The current review focuses on recent advancements, mainly from 2017–2023, of piperidine‐containing small molecule development as anti‐cancer agents. Total 10 piperidine containing anti‐cancer drugs have been approved by USFDA since 2017 to till date and around 15 small molecule anti‐cancer inhibitors containing piperidine scaffold which are in their early discovery phase have been reviewed which are classified according to their biological target. It highlights the structural contribution of piperidine ring towards the enhancement of activity or pharmacokinetic properties of diverse biological target‐specific anti‐cancer inhibitors of angiogenesis, EGFR, VEGFR, ALK, AKT1, topoisomerase, CDK2 etc. The role of the piperidine ring in enhancing potency, selectivity and bioavailability of novel molecules has been discussed. This review will be helpful to researchers, especially medicinal chemists, for the designing of piperidine‐containing potent drugs for specific biological targets for cancer.
