TariquidarTariquidar is a potent and selective noncompetitive inhibitor of P-glycoprotein with Kd of 5.1 nM in CHrB30 cell line, reverses drug resistance in MDR cell Lines. Phase 3. |
Mutations of the polar residues Y307, Q725 and Y953 to alanine, cysteine and phenylalanine (Y953F only) were tested for their effect on the modulation of basal ATPase activity of P-gp by drugs. Basal activity of cysless WT and mutant P-gps was taken as zero, inhibition was calculated as percentage of the basal activity and shown with downward bars (negative values), while stimulation was calculated as percentage of the basal activity and shown with upward bars (positive values). Bars are colored black for cysless WT or triple A (Y307A/Q725A/Y953A) while they are grey for the single mutants (Y307A/C, Q725A/C, Y953A/C/F). At least three experiments were carried out with duplicate samples for each mutant with indicated compounds, and errors bars denote the standard deviations.

Elacridar (GF120918)Elacridar (GF120918) is a potent P-gp (MDR-1) and BCRP inhibitor. |
Effect of drugs on the photo-crosslinking of cysless WT and triple A (Y307A/Q725A/Y953A) mutant P-gp with IAAP. Crude membranes expressing cysless WT or mutant P-gp (60-80 μg protein) were treated with the indicated concentrations of drug in 100 μL buffer containing 50 mM MES-Tris pH 6.8 for 10 min at 37 °C. Samples were then photo-crosslinked with 4–6 nM IAAP at 4 °C as described in Section 2. IAAP-labeling of the cysless WT and Triple A mutant P-gp with no addition of drug was taken as 100% labeling. Both panels show a representative autoradiogram (at the top) and the quantification of the IAAP-labeling (at the bottom). Lane 1, control (DMSO solvent); 2, 1 μM zosuquidar; 3, 1 μM elacridar; and 4, 1 μM tariquidar. Data represent the mean ± the standard deviations for n = 3. Left panel, cysless WT; right panel, Triple A (Y307A/Q725A/Y953A) mutant.

SC144SC144 is the first-in-class orally active small-molecule gp130 inhibitor that induces gp130 phosphorylation (S782) and deglycosylation, abrogates Stat3 phosphorylation and nuclear translocation, and further inhibits the expression of downstream target genes. |
Suppression of gp130/STAT3 blocks the protective effect of SPRC against Dox-induced cell apoptosis. Cardiomyocytes were pretreated with/without SC144 before SPRC incubation, followed by Dox (1 μM) stimulation for 24 h. (a) Morphological apoptosis was determined by Hoechst 33258 staining. Scale bars, 50 μm.
