Answer

Immunosuppressive agents

Cyclophosphamide is used in nonmalignant renal diseases for its immunosuppressive effects.

Cyclophosphamide (Neosar, Cytoxan)

Cyclic polypeptide that suppresses some humoral activity. Chemically related to nitrogen mustards. Activated in the liver to its active metabolite, 4-hydroxycyclophosphamide, which alkylates the target sites in susceptible cells in an all-or-none type reaction. As an alkylating agent, the mechanism of action of the active metabolites may involve cross-linking of DNA, which may interfere with growth of normal and neoplastic cells.

Biotransformed by cytochrome P-450 system to hydroxylated intermediates that break down to active phosphoramide mustard and acrolein. Interaction of phosphoramide mustard with DNA considered cytotoxic.

When used in autoimmune diseases, mechanism of action is thought to involve immunosuppression due to destruction of immune cells via DNA cross-linking.

In high doses, affects B cells by inhibiting clonal expansion and suppression of production of immunoglobulins. With long-term low-dose therapy, affects T cell functions.
