Rapamycinbelongs to the class of macrocyclic immunosuppressive drugs that are bioactive only when bound to immunophilins. Cyclosporin A and FK506, two other members of this class, selectively block the transcriptional activation of several cytokine genes, thereby inhibiting cytokine production.

Sirolimus was discovered from a soil sample collected in Rapa Nui, which is also known as Easter Island [ 1 ]. Rapamycin: Mechanism of Action Rapamycin is an immunosuppressive agent with potent antiproliferative and antimigratory properties on vascular smooth muscle cells. 13–15 Yet its biggest claim to fame is not in its role as an immunosuppressant, but as the active agent in drug-eluting endovascular stents. Rapamycin forms a ternary complex with the FKBP-12 and FRB domains of mTOR plausibly via an allosteric mechanism (Choi, Chen, Schreiber, & Clardy, 1996;Choo & Blenis, 2009).

cancer) (Li, Kim, & Blenis, 2014). The multitude of health applications originating from rapamycin, a secondary metabolite, stimulated research to further explore secondary metabolism and it’s benefit to human beings. The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that has been increasingly recognized as key to the regulation of cell growth and proliferation. mTOR either directly or indirectly regulates translation initiation, actin organization, tRNA synthesis, ribosome biogenesis, and many other key cell maintenance functions, including protein degradation and transcription functions. The mechanistic target of rapamycin (mTOR), previously referred to as the mammalian target of rapamycin, and sometimes called FK506-binding protein 12-rapamycin-associated protein 1 (FRAP1), is a kinase that in humans is encoded by the MTOR gene.

Understanding its mechanism of action has the potential to offer insight into the nature of the underlying aging process and may lead to new therapeutic approaches to alleviate the burden of age-related diseases.

Mechanisms of action T‐cell activation comprises two major phases. The first, which follows triggering of the T‐cell receptor, results in the transcriptional activation of cytokine genes, and leads from the quiescent T‐cell state (G0) to the competent state (G1).

To better explore the role of rapamycins against tumors, this review will summarize the current knowledge of the mechanism of action of rapamycins, and progress in understanding mechanisms of acquired or intrinsic resistance. In other words, rapamycin mechanism of action could slow down age-dependent changes or it may act by suppressing specific life-limiting pathologies (e.g. cancer) (Li, Kim, & Blenis, 2014). The multitude of health applications originating from rapamycin, a secondary metabolite, stimulated research to further explore secondary metabolism and it’s benefit to human beings.

The mechanistic target of rapamycin (mTOR), previously referred to as the mammalian target of rapamycin, and sometimes called FK506-binding protein 12-rapamycin-associated protein 1 (FRAP1), is a kinase that in humans is encoded by the MTOR gene. mTOR is a member of the phosphatidylinositol 3-kinase-related kinase family of protein kinases.

However, very little is known about the mechanism of action of rapamycin. Structurally, rapamycin resembles the immunosuppressant tacrolimus, and it has similar immunosuppressive effect and mechanism of action via the inhibition of T-and B-cells (Sehgal, 2003). Because Sirolimus (rapamycin) and everolimus are structurally very similar and have the same mechanism of action.
