Monoclonal antibody (mAb)-based immunotherapy is now established as an important option for treating some cancers. The antitumor effects may be further enhanced by combining mAb with conventional chemotherapy. Certain novel immunomodulatory mAbs such as anti-CD40 have shown significant activity in preclinical models. We therefore assessed the efficacy of combining anti-CD40 mAb, known to elicit...

Stabilities and quantum molecular descriptors of cyclophoshphamide (an anticancer drug)-functionalized (8,0) zigzag and (4,4) armchair carbon nanotubes (CNTs) complexes in water were studied using density functional theory (DFT) calculations. Two attachments namely the sidewall- and tip-attachments are considered for the model constructions. Calculations of the total electronic energy (Et) and ...

The potential metabolic drug interactions between TNP-470, a potent inhibitor of angiogenesis, and several commonly used anticancer agents, such as cyclophosphamide, taxol, and minocycline, were investigated in vitro using primary cultured hepatocytes and microsomes of rhesus monkeys. After incubation of hepatocytes with 5 microM [3H]TNP-470, rapid and extensive formation of six metabolites was...

This work focuses on P450 biosensors based on multiwalled carbon nanotubes (MWCNT) and different cytochrome isoforms: 3A4, 2B4, 2C9. The proposed biosensors exhibit enhanced sensitivities and decreased detection limits thanks to carbon nanotubes. The MWCNT structuring improves the sensitivity from 5.1 to 20.5 nA/mM mm(2) in case of CYP2B4-mediated Benzphetamine detection, from 0.26 to 0.63 nA/μ...

Paternal exposure to chemotherapeutics may have adverse effects on offspring. In the rat, chronic low-dose paternal exposure to the anticancer drug cyclophosphamide increased pre- and postimplantation loss and malformations. The effects of paternal drug treatment on progeny were influenced by the stage when germ cells were first exposed. Chronic cyclophosphamide treatment resulted in a dramatic...

Introduction: Cyclophosphamide is a chemotherapy drug with several side effects on various organs such as male reproductive system that can cause infertility. In this study, we assessed combined effect of ginger and pumpkin extractson rat testis after CP injection. Methods: Forty adult male rats were randomly divided into 4 groups: The control group received intraperitoneal injection of ...

Cytotoxic potencies of cyclophosphamide, 4-ketocyclophosphamide, carboxyphosphamide, mechlorethamine (HN2), bis(2-chloroethyl)amine (nor-HN2), chlorambucil, acrolein, and cyclophosphamide metabolites generated in vivo and in vitro were determined via bioassay. Our bioassay procedure was to incubate the potential cytotoxic agent with Walker 256 ascites cells in vitro, inject these cells into hos...

stools were determined by liquid scintillation counting. Plasma and urine alkylating activity was measured by reaction with 4-(4-nitrobenzyl)pyridine. Protein binding of cyclophosphamide and plasma alkylating metabolites were deter mined by plasma ultrafiltration. Injected Cyclophosphamide distributed rapidly into 64% of body weight, and plasma Cyclophosphamide half-life in patients without pri...

The possible protective effects of curcumin have been addressed in the current study. Cardiotoxicity was induced by challenging male Swiss albino rats with a single dose of cyclophosphamide (150 mg/kg, i.p.). Curcumin (200 mg/kg, i.p.) was administered for 8 consecutive days followed by a single dose of cyclophosphamide. Cardiotoxicity was well characterized morphologically and biochemically. T...
