Azathioprine Sodium is the sodium salt form of azathioprine, a pro-drug of purineanalogue 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.
CB10-277 is a synthetic derivative of dimethylphenyl-triazene related to dacarbazine, with antineoplastic properties. Related to the agent dacarbazine, CB10-277 is converted in vivo to a monomethyl triazene form that alkylates DNA, resulting in inhibition of DNA replication and repair; in addition, this agent may act as a purineanalogue, resulting in inhibition of DNA synthesis, and may interact with protein sulfhydryl groups.
