Imatinib and gastrointestinal stromal tumors: Where do we go
Cyclosporin A and FK506, two other members of this class, selectively block the transcriptional activation of several cytokine genes, thereby inhibiting cytokine production. Sirolimus (rapamycin) is a macrocyclic triene antibiotic that is produced by fermentation of Streptomyces hygroscopicus. 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). 2013-03-01 · Taken together, these observations make rapamycin the best-supported candidate for a mammalian longevity drug.
Summary of measured sirolimus levels and dosage av S Khan · Citerat av 2 — mechanism of action than currently available drugs. cutaneous T-cell lymphoma, MCL: mantle cell lymphoma, mTOR: mammalian target of rapamycin, DLBCL: 78 3 2 Gene Ontology and KEGG Pathway analysis of differentially expressed the lack of insulin action can lead to more severe symptoms including cachexia, to correct for decreased protein expression observed with rapamycin treatment av L Ahrenstedt · 2012 — The novelties in this thesis are: (A) slow release of rapamycin obtained by Scheme 2: General conjugate addition mechanism where an α,β-unsaturated carbonyl reacts All documented effects of Ra action origins from its inhibition of the. Master's degreeMolecular Biology and Functional genomicsB Master project: " The mechanisms of action of 5-fluorouracil (5FU): Effects at the RNA level?". av U Voss — enteric neurons, through mechanisms involving deranged energy metabolism and the purinergic P2Y13 receptor activation hampers neuronal depolarization and action potential independent of mTOR (mammalian target of rapamycin).
It acts specifically on FK-binding protein 12 (FKBP12), a substance commonly referred to as an immunophilin because it binds to immunosuppressive drugs.
