Density functional theory (DFT) calculations were performed on tripeptide arginyl-glycyl-aspartic acid (RGD) as an efficient drug carrier to deliver the commercially famous cyclophosphamide (CP) anticancer drug within ethanol solution. The most negative binding energy (-5.22 kcal/mol) was measured for the CP-RGD-7 created through the H-bond interaction between the P=O (phosphoryl) oxygen atom o...

Preconceptional paternal exposure to cyclophosphamide, a widely used anticancer agent, leads to increases in embryo loss, malformations, and behavioral deficits in offspring; these abnormalities are transmissible to subsequent generations [Auroux, M., Dulioust, E., Selva, J. & Rince, P. (1990) Mutat. Res. 229, 189-200]. Little information exists on the mechanisms underlying this male-mediated d...

Although combination chemotherapy regimens may prolong survival for selected patients with metastatic breast cancer, few, if any, are cured. The standard regimens used in treatment, e.g., CMF (cyclophosphamide, methotrexate, and fluorouracil [5-FU]), FAC (5-FU, Adriamycin, and cyclophosphamide), and FEC (5-FU, epirubicin, and cyclophosphamide), were developed over a decade ago. Current efforts ...

Recovery from specific immunological tolerance to sheep erythrocytes induced with the drug cyclophosphamide was studied with the hemolytic plaque technique of Jerne. The base line plaque (19S antibody-forming cell of the unstimulated spleen) and the proliferative response to antigen, both of which had disappeared during tolerance induction, returned with the recovery of specific immunological r...

OBJECTIVE To assess pulmonologists' use, training in the use, and knowledge base of the drug cyclophosphamide. DESIGN Survey through questionnaire. Testing of knowledge base before and after instructional conference. PARTICIPANTS AND METHODS Pulmonologists (94 attendings, 31 fellows), selected randomly at the 1996 and 1997 annual meetings of The American Thoracic Society, completed surveys ...

BACKGROUND: The causal relationship between mutagenesis and carcinogenesis is well known. Hence the wide interest in study of mutagen-modifying effects natural synthetic compounds. Particular attention drawn to widespread One them, metformin, widely used as a hypoglycemic drug.
 AIM: evaluation influence metformin on cytogenetic doxorubicin cyclophosphamide mouse bone marrow cells.
 M...

We read with interest the recent publications by Ariyoshi et al. (2011) and Raccor et al. (2011). The role of a number of cytochrome P450 (P450) isozymes in the 4-hydroxylation of cyclophosphamide has been debated for several years. There is evidence that both CYP2B6 and CYP2C19 are important in the biotransformation and activation of this prodrug in vitro (Chang et al., 1993, 1997; Huang et al...
