Design of high-affinity peptide conjugates with optimized fluorescence quantum yield as markers for small peptide transporter PEPT1 (SLC15A1)
摘要:
We employed a computational approach to design and synthesize a series of. fluorescently labeled hPEPT1 substrates. Five Alexa Fluor-350 (TM)-labeled peptides were assessed for their in vitro inhibitory activity in hPEPT1-transfected CHO cells. At least four labeled peptides show potent inhibitory activity toward hPEPT1-mediated uptake of [H-3]-GlySar and three compounds displayed a significant cellular uptake specifically mediated by hPEPT1.
