mTOR inhibitors are a class of drugs used to treat several human diseases, including cancer, autoimmune diseases, and neurodegeneration. They function by inhibiting the mammalian target of rapamycin (mTOR) (also known as the mechanistic target of rapamycin), which is a serine/threonine-specific protein kinase that belongs to the family of phosphatidylinositol-3 kinase (PI3K) related kinases ...
Sirolimus (rapamycin, trade name Rapamune) is a macrolide lactone, produced by the actinomycete bacterium Streptomyces hygroscopicus. It is used to prevent rejection reactions. Although it is a structural analogue of tacrolimus, it acts somewhat differently and has different side-effects.
Sirolimus, also known as rapamycin and sold under the brand name Rapamune among others, is a macrolide compound that is used to coat coronary stents, prevent organ transplant rejection, treat a rare lung disease called lymphangioleiomyomatosis, and treat perivascular epithelioid cell tumour (PEComa).
An anti-rejection-type medication, sirolimus, helps to limit the overgrowth of normal cells while the artery heals which reduces the chance of re-blockage in the treated area known as restenosis, and reduces the chances that another procedure is required. [1] [2] The Cypher stent was approved for use by the FDA in 2003. [2]
NHS England has been criticised for delays in deciding on a policy for the prescription of everolimus in the treatment of Tuberous Sclerosis. 20 doctors addressed a letter to the board in support of the charity Tuberous Sclerosis Association saying " around 32 patients with critical need, whose doctors believe everolimus treatment is their best or only option, have no hope of access to funding.
Temsirolimus is a specific inhibitor of mTOR and interferes with the synthesis of proteins that regulate proliferation, growth, and survival of tumor cells. Though temsirolimus shows activity on its own, it is also known to be converted to sirolimus (rapamycin) in vivo; [4] therefore, its activity may be more attributed to its metabolite rather than the prodrug itself (despite claims to the ...
Umirolimus (INN/USAN, also called Biolimus) is an immunosuppressant, a macrocyclic lactone, a highly lipophilic derivative of sirolimus.This drug is proprietary to Biosensors International, which uses it in its own drug-eluting stents, and licenses it to partners such as Terumo.
Sirolimus (also known as rapamycin) is an antifungal and immunosuppressant that has been isolated from S. hygroscopicus from soil samples from Easter Island. [4] Ascomycin is another immunosuppressant produced by some strains of S. hygroscopicus; it has a similar structure to sirolimus and can be used to treat autoimmune diseases and skin diseases and can help prevent rejection after an organ ...
