Cyclophosphamide is an alkylating agent with cytotoxic and immunosuppressive activities. Cyclophosphamide requires enzymatic and chemical activation to release active phosphoramide mustard which produces the interstrand and intrastrand DNA crosslinks at guanine N-7 positions. Cyclophosphamide exerts its cytotoxic activity by inhibiting nuclear DNA replication. The mechanism of Cyclophosphamide -induced immunosuppression is possibly due to direct cytotoxic effect of the drug on immunocompetent lymphocytes, particulafly those that have undergone antigenic differentiation and division. Cyclophosphamide has its greatest effect on B cells with relative T cell-sparing effect. [1] Trials in various tumor-bearing animals confirmed this in vivo activity and demonstrated fairly potent antitumor effect. Cyclophosphamide, in combination with other antineoplastic agents, is used for the treatment of various cancers, including breast, lymphoid and pediatric malignancies. [2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Frequently Asked Questions

Question 1:
Why S1217 Cyclophosphamide shows no activity in vitro assays?

Answer:
The activity of this product in vitro is controversial and has not been fully determined. Cyclophosphamide 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.
