PR-104 Quick inquiry Where to buy Suppliers range | PR-104 is a non-toxic, small-molecule, hypoxia-activated, 3,5-dinitrobenzamide nitrogen mustard pre-prodrug with potential antitumor activity. Upon intravenous administration, PR-104 is converted by systemic phosphatases to the alcohol intermediate PR-104A, which is reduced to form the active DNA-crosslinking mustard species hydroxylamine PR-104H intracellularly under hypoxic conditions. PR-104H specifically crosslinks hypoxic tumor cell DNA, resulting in the inhibition of DNA repair and synthesis, cell-cycle arrest, and apoptosis in susceptible hypoxic tumor cell populations while sparing normoxic tissues. Synonyms: PR 104; PR104; 2- ( (2-Bromoethyl) (2, 4-dinitro-6- ( (2- (phosphonooxy) ethyl) carbamoyl) phenyl) amino) ethyl methanesulfonate; Benzamide, 2-[(2-bromoethyl)[2-[(methylsulfonyl)oxy]ethyl]amino]-3,5-dinitro-N-[2-(phosphonooxy)ethyl]-.
