Cyclophosphamide mechanism of action

The effects of cyclophosphamide an antinuclear antibody levels, immune complex deposition in renal glomeruli, glomerular cell proliferation and glomerulosclerosis in the (NZB x NZW)F1 hybrid mouse have been investigated in order to better understand the mechanism of action of this drug on nephritis Cyclophosphamide is commonly used with doxorubicin (hydroxydaunorubicin), vincristine (oncovin), and prednisone (known as the CHOP regimen), with or without other agents, in the treatment of various types of intermediate-grade non-Hodgkin lymphoma. Cyclophosphamide has also been used as a single agent in the treatment of low-grade lymphomas Mechanism of action. The main effect of cyclophosphamide is due to its metabolite phosphoramide mustard. This metabolite is only formed in cells that have low levels of ALDH. Phosphoramide mustard forms DNA crosslinks both between and within DNA strands at guanine N-7 positions (known as interstrand and intrastrand crosslinkages, respectively)

The human pharmacology of cyclophosphamide was investigated in 26 patients who received cyclophosphamide 14C in doses of 6 to 80 mg/kg i.v. Levels of the intact drug in plasma and urine and excretion of 14C label in breath and stools were determined by liquid scintillation counting. Plasma and urine alkylating activity was measured by reaction with 4-(4-nitrobenzyl)pyridine Although cyclophosphamide (CP) has been used successfully in the clinic for over 50 years, it has so far not been possible to elucidate the mechanism of action and to use it for improvement. This was not possible because the basis of the mechanism of action of CP, which was found by lucky coincidence, is apoptosis, the discovery of which was honored with the Nobel Prize only in 2002

Mechanism of action of posttransplantation cyclophosphamide: more than meets the eye. Text. PDF. Abstract. For high-risk and refractory hematological malignancies, allogeneic hematopoietic stem cell transplantation (alloHSCT) is the only available curative therapy, with benefits derived from the antigenic disparity between recipient cancer and. Interstitial lung disease (ILD) is the primary cause of death in patients with systemic sclerosis (SSc). It is thought that chronic inflammation is a key component in SSc-ILD. Treatment, such as cyclophosphamide (CYC), targets this inflammation. We hypothesized that treatment with CYC might be more effective in the inflammatory phase. Therefore, we analyzed whether the extent of inflammation. Cyclophosphamide can be administered at metronomic dosing, such as chronic administration of low doses at close regular intervals without prolonged drug-free interruptions. 11,12 Preclinical and clinical studies have reported the efficacy of this strategy in prostate cancer. 13-15 In 2 studies, a 50% reduction in PSA was noted in 23.5% and 64.7.
