Abstract

Transmembrane efflux pumps play an increasing role in the success of ART. The occurrence of increasing mRNA levels of the efflux pump proteins P-gp and MRP subtypes has been associated with ART therapeutics like PIs and NNRTIs. Moreover, a relation has been suggested of MRP subtypes and CD4 cell counts. So there is a challenge to find selective MRP inhibitors which may reduce MRP-induced drug resistances as well as discussed effects on CD4 cells. We developed novel nonpeptidic inhibitors of important MRP subtypes related to both MRP-mediated resistances as well as reduced cell counts.
