title: Novel insight in structure-activity relationship and bioanalysis of P-glycoprotein targeting highly potent tetrakishydroxymethyl substituted 3,9-diazatetraasteranes.
abstract: Novel 3,9-diazatetraasteranes have been synthesized with varied aromatic substitution patterns and evaluated as P-glycoprotein (P-gp) inhibitors. Structure-activity relationships (SAR) are discussed in relation to determined physicochemical properties. The potential to induce P-gp expression has been evaluated in cancer cell lines. The bioanalytical results indicate favorable noninducing properties compared to P-gp inducing drug standard.
