The effect of ivermectin alone and in combination with cobicistat or elacridar in experimental Schistosoma mansoni infection in mice
102 views | Mar 10 2021
Belén Vicente et al. thought that even in the presence of pharmacological inhibition of P-glycoprotein or cytochrome P450 3A, did not result in effective prophylaxis for S. mansoni infection in an experimental murine model. [Read the Full Post]
Optimization of dose and route of administration of the P-glycoprotein inhibitor, valspodar (PSC-833) and the P-glycoprotein and breast cancer resistance protein dual-inhibitor, elacridar (GF120918) as dual infusion in rats
99 views | Mar 09 2021
Christopher Rowbottom rt al. demonstrated that doses greater than 0.9 mg/hr/kg valspodar and 8.9 mg/hr/kg elacridar were sufficient to inhibit P-gp- and BCRP-mediated efflux at the blood-brain barrier in rats without any tolerability issues. [Read the Full Post]
Relation of Metal-Binding Property and Selective Toxicity of 8-Hydroxyquinoline Derived Mannich Bases Targeting Multidrug Resistant Cancer Cells
108 views | Jan 31 2021
Veronika F S Pape et al. showed that the MDR-selective anticancer activity of the studied 8-hydroxyquinoline derived Mannich bases was associated with the iron deprivation of MDR cells and the preferential formation of redox-active copper(II) complexes, which underwent intracellular redox-cycling to induce oxidative stress.

Drug-protein hydrogen bonds govern the inhibition of the ATP hydrolysis of the multidrug transporter P-glycoprotein
0 views | Nov 20 2018
Chufan EE et al. revealed that screening chemical compounds for their ability to inhibit the basal ATP hydrolysis can be a reliable tool to identify modulators with high affinity for P-gp. [Read the Full Post]
The Nonmetabolized β-Blocker Nadolol Is a Substrate of OCT1, OCT2, MATE1, MATE2-K, and P-Glycoprotein, but Not of OATP1B1 and OATP1B3
1925 views | Sep 05 2018
Misaka S et al. indicated that these data will aid future in vivo studies on potential transporter-mediated drug-drug or drug-food interactions with involvement of nadolol. [Read the Full Post]

Wu J et al. offered a novel molecular basis and therapeutic strategy of H2S donor for the treatment of heart failure. [Read the Full Post]
Prospective identification of resistance mechanisms to HSP90 inhibition in KRAS mutant cancer cells
1212 views | Jan 20 2018
Rouhi A et al. identified potential mechanisms of acquired resistance to small molecules targeting HSP90 that may warrant proactive screening for additional HSP90 inhibitors or rational combination therapies. [Read the Full Post]
Jatrophane Diterpenoids as Modulators of P-Glycoprotein-Dependent Multidrug Resistance (MDR): Advances of Structure-Activity Relationships and Discovery of Promising MDR Reversal Agents
0 views | Jun 24 2017
Zhu J et al. showed that modifications beyond just increasing the lipophilicity of this class of Pgp inhibitors are beneficial to the activity. [Read the Full Post]
Jatrophane Diterpenoids as Modulators of P-Glycoprotein-Dependent Multidrug Resistance (MDR): Advances of Structure-Activity Relationships and Discovery of Promising MDR Reversal Agents
2250 views | Dec 28 2016
Zhu J, et al found that compound 26, which exhibited a remarkable metabolic stability in vitro and a favorable antitumor effect in vivo, would serve as a promising lead for the development of new MDR reversal agents. [Read the Full Post]
