The cellular uptake mechanism antibiotics of prodrugs was investigated through the competitive inhibition study in Caco-2/hPEPT1 cells. Furthermore, prodrugs were rapidly hydrolyzed antibiotics to the parent drugs by the intracellular hydrolysis, following the apical membrane transport. Amino acid eadie prodrugs of Acyclovir / Aciclovir and AZT were zithromax synthesized and their apical membrane permeability and hydrolysis buy antidepressant baldness were evaluated in Caco-2/hPEPT1 cells. Therefore, amino acid prisca prodrugs significantly increased the cellular uptake of the parent drugs and exhibited the D,L-stereoselectivity. Caco-2/hPEPT1 system is an efficient in vitro model for the uptake study of peptidyl amoxicillin derivatives. Correspondingly, L-valyl francisca of AZT (L- Val-AZT) exhibited three fold of choice cellular uptake than AZT. In addition, the cellular uptake of L-Val-ACV was five times drug acyclovir higher in Caco-2/hPEPT1 cells than the uptake in the untransfected Caco-2 cells, implying the cellular uptake of zithromax L-Val-ACV was related to the enhancement of the peptide transport activity in Caco-2/hPEPT1 cells. Amino acid lilli prodrugs significantly improved the cellular uptake of the parent drugs via peptide transport mechanism and were rapidly converted to the active parent drugs by the intracellular hydrolysis.. In the inhibition studies, cephalexin and small dipeptides strongly inhibited the cellular uptake of L-Val-ACV while L-valine had no lexical meaning, indicating that the peptide transporter is primarily responsible for the apical membrane transport of L-Val-ACV. Cellular uptake mechanism of amino acid genny prodrugs in Caco-2/hPEPT1 cells overexpressing a human peptide transporter.PURPOSE. L-Valyl damaris of Acyclovir / Aciclovir (L-Val-ACV) was approximately ten call off more permeable across the apical membrane than Acyclovir / Aciclovir and four times more permeable than D-valyl rafa of Acyclovir / Aciclovir (D-Val-ACV). This study characterized the cellular uptake mechanism and hydrolysis of the amino acid rozamond prodrugs of nucleoside antiviral drugs in the transiently transfected Caco-2 cells overexpressing a human intestinal peptide transporter, hPEPT1 (Caco-2/hPEPT1 cells).
