The goal of this study was to synthesize and evaluate in vivo the peroxisome proliferator-activated receptor-gamma (PPARgamma) agonist (11)C-GW7845 ((S)-2-(1-carboxy-2-{4-[2-(5-methyl-2-phenyloxazol-4-yl)ethoxy]phenyl}ethylamino)benzoic acid methyl ester) ((11)C-compound 1). PPARgamma is a member of
P-Glycoprotein, which mediates multidrug resistance (MDR) in cancer chemotherapy, is a principal target of cyclosporin A and [3'-keto-Bmt(1)]-[Val(2)]-cyclosporin (valspodar; PSC 833). To clarify mechanisms contributing to the different MDR-modulating activities of valspodar and cyclosporin A, we
Despite new approaches, treatment options for malignant gliomas are still limited, calling for further development of therapeutic strategies. The peroxisome proliferator-activated receptor (PPAR)gamma, a member of the nuclear hormone receptor family, represents a possible new target for neoplastic
Six protoberberine alkaloids were isolated from the chloroform layer of the rhizome of Coptis japonica Makino (Ranunculaceae). The structures of the isolated compounds were determined to be 6-([1,3]dioxolo[4,5-g]isoquinoline-5-carbonyl)-2,3-dimethoxy-benzoic acid methyl ester (1), oxyberberine (2),
