WebTamoxifen (TAM) is widely used in the treatment of hormone receptor-positive breast cancer. TAM is metabolized into the active secondary metabolite endoxifen (ENDO), primarily by CYP2D6. We aimed to investigate the effects of an African-specific CYP2D6 variant allele, CYP2D6*17, on the pharmacokinetics (PK) of TAM and its active … WebInvestigation of metabolite kinetics, however, revealed that the rate of formation of NORA was preferentially decreased, whereas that of OHA and HMA were unaltered. Renal clearance of the metabolites of antipyrine was severely impaired in patients with renal insufficiency, and the resulting accumulation made it possible for the first-time to …

WebMetabolites are the products and intermediates of cellular metabolism. Metabolites can have a multitude of functions, including energy conversion, signaling, epigenetic influence, and cofactor activity (Lu and Thompson, 2012; Wellen and Thompson, 2012 ). WebA physiological approach to the simulation of mDDIs requires a range of data on tissue blood flow rates and tissue uptake, plasma protein binding, and nonspecific binding of compounds to the in vitro metabolizing system (hepatocytes, liver microsomes, or rhCYPs, enzyme kinetic data (in the form of CL int for substrates and Ki values for … WebAbstract.
