MTOR INHIBITORS IN ONCOLOGY
• mTOR better known as the mammalian target of rapamycin is a protein kinase that governs many cellular functions. It forms two specific multiprotein complexes, specified mTOR complexes 1 and 2 (mTORC1 and mTORC2).
• Each complex plays master roles in cellular regulation. mTORC1 controls multiple anabolic pathways, which can also include protein synthesis, lipogenesis, ribosome production, and nucleotide synthesis, all of them is important for cell and tissue growth. mTORC1 also suppresses autophagy which is a primary catabolic process. mTORC1 suppresses the production of lysosomes, the organelles responsible for autophagy.
• Also, it alters the activity and subcellular localization of cellular regulations by phosphorylation of the proteins involved in these pathways.
• An elementary characteristic of cancer cells is their ability to nurture continued proliferation in the absence of growth-promoting signals.
• This characteristic is successful in part by genetic events that cause exceptional activation of mTORC1 signaling: mTORC1 signaling is hyperactive in most of the cancers. Inhibiting mTORC1 signaling has, therefore, captivating great attention from cancer researchers as a potential therapy.
• As both the bioavailability and solubility of rapamycin are low, more soluble rapamycin derivatives analogs called rapalogs are developed.
• Emerging economies and increase in adoption of mTOR inhibitors for various types of cancers have proved to provide excellent opportunities in the field. Increase in the diagnosed population in a variety of cancers, about 1.7 million new cancer cases are expected to be diagnosed in 2018 and growing demand for the mTOR inhibitors at patient level certainly can foresee a positive growth of the market.
• However, to avail these benefits, researchers and investors have to concentrate on cost employed for research and development, complexity in the mechanism of action.
• To overcome the challenges due to changes, make cancer cells resistant to a drug, researchers have to develop next-generation therapies. The first generation of mTOR inhibitors like Afinitor, Torisel were approved more than a decade ago, recent developments are noticed to overcome the resistance of these drugs in cancer.
• More than 60 molecules are under development in various stages. Majority of the products are in the mid-level stage of development. BN-107 of Bionovo, ME-344 of MEI Pharma are in Phase 2 whereas DS-3078 of Daiichi, CC-115 of Celgene are in the early clinical stage of development. About 18 molecules are in the preclinical stage of development some of them include SB2602 of S*BIO, OXA 01 of Astellas, XL388 of Exelixis.
