General description

Cyclophosphamide (CYC) is a cytotoxic alkylating agent. It is activated by the cytochrome P-450 enzyme system in the liver. It has immunomodulatory functionality and inhibits humoral and cellular immunity.


Cyclophosphamide monohydrate has been used:
  • to test its antitumor effect on TC-1 tumor cells
  • as a component of multidrug solution for isolation of resistant human burkitt lymphoma cell line
  • in testing antitumor immunity in mouse tumor cell lines


1, 5, 10, 25 g in glass bottle

Biochem/physiol Actions

Cyclophosphamide is a cytotoxic nitrogen mustard derivative widely used in cancer chemotherapy. It cross-links DNA, causes strand breakage, and induces mutations. Its clinical activity is associated with a decrease in aldehyde dehydrogenase 1 (ALDH1) activity.

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
