Mechanism of Action

In vitro	Cyclophosphamide (CY) is a chemotherapeutic agent with a dose-dependent, bimodal effect on the immune system. Cyclophosphamide treatment enhances apoptosis and decreases homeostatic proliferation of regulatory T cells. Cyclophosphamide downregulates the expression of GITR and FoxP3, which are involved in the suppressive activity of T(REGs). Cyclophosphamide increases CYP3A4, CYP2C8, and CYP2C9 protein levels in primary human hepatocyte cultures, which thereby enhances their own rates of 4-hydroxylation in the cultured hepatocytes. Cyclophosphamide has produced mutations in base-pair substituting strains of Salmonella tryphimurium in the presence of metabolic activation, but it has been shown to be negative in the E. coli chromotest. Cyclophosphamide has been shown to produce gene mutations, chromosome aberrations, micronuclei and sister chromatid exchanges in a variety of cultured cells in the presence of metabolic activation as well as sister chromatid exchanges without metabolic activation.
In vivo	Cyclophosphamide has also produced chromosome damage and micronuclei in rats, mice and Chinese hamsters, and gene mutations in the mouse spot test and in the transgenic lacZ construct of Muta Mouse. Cyclophosphamide, when given in a defined sequence with a GM-CSF-secreting, neu-expressing whole-cell vaccine, enhances the vaccine's potential to delay tumor growth in neu transgenic mice. Cyclophosphamide mediates its effects by enhancing the efficacy of the vaccine rather than via a direct cytolytic effect on cancer cells.

Frequently Asked Questions

Question 1:
Why does it show no activity in vitro assays?

Answer:
The activity of this compound in vitro is controversial and has not been fully determined. It is a prodrug and may need Cytochrome P450 to convert it to the active form: 4-hydroxy cyclophosphamide. It is widely used in vivo, if you are going to use it in vitro, you may need to supplement Cytochrome P450 exogenously.
