Mycophenolic acid is an immunosuppressant medication used to prevent rejection following organ transplantation and to treat autoimmune conditions such as Crohn's disease and lupus. [ 12 ] [ 13 ] Specifically it is used following kidney , heart , and liver transplantation . [ 13 ]
Mycophenolic acid acts as a non-competitive, selective, and reversible inhibitor of inosine-5′-monophosphate dehydrogenase (IMPDH), which is a key enzyme in the de novo guanosine nucleotide synthesis. In contrast to other human cell types, lymphocytes B and T are very dependent on this process.
Myricetin provided protection against the formation of skin tumors in mice models after tumor initiating and tumor promoter agents were applied to the skin. On a more biochemical level, it was shown that topical application of myricetin to mice inhibited the binding of benzo(a)pyrenes to DNA and protein native to epidermal skin cells. [1]
The risk of cSCC, and non-melanoma skin cancers generally, varies with the immunosuppressive drug regimen chosen. The risk is greatest with calcineurin inhibitors like cyclosporine and tacrolimus, and least with mTOR inhibitors, such as sirolimus and everolimus. The antimetabolites azathioprine and mycophenolic acid have an intermediate risk ...
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 ...
Ciclosporin, also spelled cyclosporine and cyclosporin, is a calcineurin inhibitor, used as an immunosuppressant medication.It is taken orally or intravenously for rheumatoid arthritis, psoriasis, Crohn's disease, nephrotic syndrome, eczema, and in organ transplants to prevent rejection.
However, this can be possible: for example, inhibitors based on the compounds mycophenolic acid and tiazofurin inhibit IMP dehydrogenase at the NAD + binding site. Because of the importance of this enzyme in purine metabolism, these compounds may be useful as anti-cancer, anti-viral, or immunosuppressive drugs.
mycophenolic acid O-acyl-glucuronide + H 2 O mycophenolate + D-glucuronate This liver enzyme deglucuronidates mycophenolic acid O -acyl-glucuronide. Mycophenolic acid acyl-glucuronide (AcMPAG) is an important product in the metabolism of mycophenolic acid, and ABHD10 is the major esterase responsible for the AcMPAG and probenecid acyl ...
