1 NORMAL TSC GENE FUNCTION “…rapamycin is currently the most effective and reproducible pharmacological approach for directly targeting the aging process to increase life span…” - Matt Kaeberlein, PHD Mechanism of Action Unlike the similarly named tacrolimus , sirolimus is not a calcineurin inhibitor, but it has a similar suppressive effect on the immune system. Sirolimus inhibits the response to interleukin-2 (IL-2), and thereby blocks activation of T- and B-cells. Rapamycin (rapa) and Genistein (GEN) and have characterised their mechanism of action using high-throughput strategies. A combination of microarray and 4-plex iTRAQ based approach was adopted to study the effects of rapa on MV4-11 and THP-1 cells and an 8-plex 1. Nephrologie. 1992;13(3):137.

In 2009, a drug called rapamycin was shown to extend the life span of mice by Some studies show that metformin inhibits the mTOR-pathway with an B1 MPA Medroxyprogesteronacetat mTOR Mammalian target of rapamycin mTORC1, -2 mTOR Another surprise from Metformin: novel mechanism of action via K-Ras synthesis, thus maximising insulin secretion will maximally potentiate this action.

Rapamune® (RAPA, rapamycin, sirolimus): mechanism of action immunosuppressive effect results from blockade of signal transduction and inhibition of cell Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties. Type: Small Molecule Mechanism of action. Sirolimus 7 Nov 2017 Early insights into the mechanism of action of rapamycin came from the finding that FK506 and rapamycin inhibit different aspects of immune cell Although rapamycin and its structural analog FK506 bind to the same immunophilin (FKBP), rapamycin acts at a later stage in T-cell cycle progression by blocking 1 May 2018 Attributing to their antiproliferative effect, both rapamycin and polycystic kidney disease in Han:SPRD rats: a study of the mechanism of action. 21 May 2016 However, significant discussion has surrounded the mechanism of action by which rapamycin promotes lifespan and whether it is a true antiaging 9 Mar 2016 The mammalian target of rapamycin (mTOR) is a serine/threonine kinase of the PI3K/AKT signalling pathway.

Mechanistic target of rapamycin, cancer, rapamycin, rapalog, clinical trial, resistance Rapalogs elicit the same mechanism of action as rapamycin.

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). 2013-03-01 · Taken together, these observations make rapamycin the best-supported candidate for a mammalian longevity drug. 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.

Huang et al (2003) Cancer Biol Ther 2(3) : 222-32 . PubMedID: 12878853 The chemistry, pharmacology and mechanism of action Rapamycin is a macrocyclic-triene antibiotic possessing potent immunosuppressant activity. It has been found to be a useful probe for studying T-cell signal transduction.11,12 Rapamycin exerts its immunosuppressant effect only after binding to the immunophilin proteins, FKBP12. Rapamycin inhibits NCI played a key role in the discovery of the anticancer properties of rapamycin and its mechanism of action. This discovery led to research detailing the role of the mTOR protein in promoting cancer development and progression. Rapamycin is a macrolide fungicide with immunosup-pressant properties that bear molecular structural simi-larities to the calcineurin inhibitor, tacrolimus (13). How-ever, the mechanism of action of rapamycin is distinct from that of calcineurin inhibitor, such as cyclosporine and tacrolimus.

In addition, the status of ATM, p53, PTEN/Akt and 14-3-3 are also associated with rapamycin sensitivity. 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).
