United States. In Curr Drug Targets, Jun 2013
Covered topics include schedule/dose modification, intestinal alkalization, structural/chemical modification, genetic testing, anti-diarrheal therapies, transporter (ABCB1, ABCC2, BCRP2) inhibitors, enzyme (β-glucuronidase, UGT1A1, CYP3A4, carboxylesterase, COX-2) inducers and inhibitors, probiotics, antibiotics, adsorbing agents, cytokine and growth factor activators and inhibitors and other miscellaneous agents.
The role of human carboxylesterases in drug metabolism: have we overlooked their importance?
Memphis, United States. In Pharmacotherapy, Feb 2013
It has been widely believed that drugs undergoing hydrolysis by hCE1 and hCE2 are not subject to clinically significant alterations in their disposition, but evidence exists that genetic polymorphisms, drug-drug interactions, drug-disease interactions and other factors are important determinants of the variability in the therapeutic response to carboxylesterase-substrate drugs.
Enzyme-catalyzed activation of anticancer prodrugs.
Amsterdam, Netherlands. In Pharmacol Rev, 2004
The following endogenous enzymes are discussed: aldehyde oxidase, amino acid oxidase, cytochrome P450 reductase, DT-diaphorase, cytochrome P450, tyrosinase, thymidylate synthase, thymidine phosphorylase, glutathione S-transferase, deoxycytidine kinase, carboxylesterase, alkaline phosphatase, beta-glucuronidase and cysteine conjugate beta-lyase.
Modulation of irinotecan metabolism by ketoconazole.
Rotterdam, Netherlands. In J Clin Oncol, 2002
RESULTS: With ketoconazole coadministration, the relative formation of APC was reduced by 87% (P =.002), whereas the relative exposure to the carboxylesterase-mediated SN-38 as expected on the basis of dose (area under the plasma concentration-time curve normalized to dose) was increased by 109% (P =.004).
