Alkylating cytostatics

Cyclophosphamide in transplant

Cyclophosphamide is a cyclic phosphamide ester of mechlorethamine. It is transformed via hepatic and intracellular enzymes to active alkylating metabolites, acrolein and phosphoramide mustard.

Cyclophosphamide causes prevention of cell division primarily by cross-linking DNA strands. It is considered to be cell cycle phase-nonspecific. Immune modulation with cyclophosphamide (and plasmapheresis, and intravenous gamma globulin) are methods used to desensitize transplant candidates with preformed anti-HLA antibodies to achieve successful transplantation.
