Fragment-based Drug Discovery Successful Contributions to Current Pharmacotherapeutic Agents Arsenal against Aggressive Cancers: A Mini-Review

Abstract

After a decade of approval of the drug vemurafenib in 2011, the hopeless scenario imposed by some severe cancer types has been mitigated by the magic bullets developed through fragment-based drug discovery. Moreover, this recent approach to medicinal chemistry has been successfully practiced by academic laboratories and pharmaceutical industry workflows focused on drug design with an enhanced profile for chemotherapy of aggressive tumors. This mini-review highlights the successes achieved by these research campaigns in the fruitful field of the molecular fragment paradigm that resulted in the approval of six new anticancer drugs in the last decade (2011-2021), as well as several promising clinical candidates. It is a particularly encouraging opportunity for other researchers who want to become aware of the applicability and potency of this new paradigm applied to the design and development of powerful molecular weapons in the constant war against these merciless scourges of humanity.
