Apexbio Technology LLC Cyclophosphamide 50-18-0 200mg
SDP

Cyclophosphamide is a nitrogen mustard alkylating prodrug activated via hepatic enzymes to its active metabolites These metabolites alkylate DNA primarily at guanine residues resulting in DNA cross-linking strand breaks and mutations consequently triggering cytotoxic effects Cyclophosphamide exhibits cytotoxicity in vitro with an IC50 of 37 6 M in mouse embryo BALB/c 3T3 cells and an IC50 of 8 79 M against human HL60 cells It impacts immune regulation by decreasing regulatory T cell counts and suppressive marker expression (FoxP3 GITR) facilitating immune response modulation Commonly applied in cancer and immunological research cyclophosphamide is also employed in genotoxicity assays due to its capacity to induce chromosomal aberrations and mutations
