azathioprine

Azathioprine (BW 57-322), an immunosuppressive agent, inhibits purine synthesis and GTP-binding protein Rac1 activation.

Azathioprine-d3 is a deuterated compound of Azathioprine. Azathioprine has a CAS number of 446-86-6. Azathioprine, an immunosuppressive agent, inhibits purine synthesis and GTP-binding protein Rac1 activation.

Azathioprine Sodium is the sodium salt form of azathioprine, a pro-drug of purine analogue with immunosuppressive activity. Azathioprine is converted in vivo to its active metabolite 6-mercaptopurine (6-MP), which substitutes for the normal nucleoside and mistakenly gets incorporated into DNA sequences. This leads to inhibition of DNA, RNA, and protein synthesis. As a result, cell proliferation may be inhibited, particularly in lymphocytes and leukocytes.

Mycophenolic Acid Impurity (5,7-dihydroxy-4-methylphthalide) is an an immunosuppresant drug and potent anti-proliferative, and can be used in place of the older anti-proliferative azathioprine. It is usually used as part of triple therapy including a calcineurin inhibitor (ciclosporin or tacrolimus) and prednisolone. It is also useful in research for the selection of animal cells that express the E. coli gene coding for XGPRT (xanthine guanine phosphoribosyltransferase).

6-Thioguanosine (6-Mercaptoguanosine) is an active nucleoside, a metabolite of Azathioprine, and a low molecular weight gel.6-Thioguanosine is immunosuppressive and has been used to study the formation of the RNA double helix.
