Conditional patched mutant tumor cells were treated with increasing concentrations cyclophosphamide (D), alone or in combination with 10 nmol/L BI-2536. Cells were cultured for 48 hours, pulsed with 3H-Td, and harvested for analysis of 3H-Td incorporation at 66 hours. Data represent means of triplicate samples ± SEM.

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. |

|Water||7 mg/mL (25.08 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+30% PEG 300+5% Tween 80+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
Why S2057 Cyclophosphamide Monohydrate shows no activity in vitro assays?
Cyclophoshamide is a prodrug and needs Pytochrome 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'll have to supplement Pytochrome P450 exogenously.
