BACKGROUND AND OBJECTIVE: Concurrent usage of proton pump inhibitors and their effect on survival and medication termination has been found in individuals receiving protein kinase inhibitor chemotherapy. To investigate the drug-drug interaction mechanism between CDK inhibitors and proton pump inhibitors, the in-silico docking approach was designed by applying computer simulation modules to predict the binding and inhibitory potential. METHODS: The interaction potential of proton pump inhibitors and CDK inhibitors was predicted utilising molecular docking techniques that employed Schrödinger algorithms to capture the dynamics of the CYP450 enzyme-inhibitor interaction between proton pump inhibitors and CDK inhibitors. Additionally, the human liver microsomes assay was used to determine the in vitro half-maximal inhibitory concentration (IC50) of proton pump inhibitors and the inactivation of CDK inhibitors via CYP3A4. RESULTS: Proton pump inhibitors alter the conformation of the CYP3A4 and CYP2C19 enzymes and interact with the heme prosthetic group, as determined by docking studies. It may result in the suppression of CDK inhibitors’ metabolism via competitive inhibition at the binding site of an enzyme. Omeprazole and rabeprazole both significantly block midazolam’s 1′-hydroxylation by CYP3A4 in vitro, with IC50 values of 9.86μM and 9.71μM, respectively. When omeprazole and rabeprazole are co-incubated in human liver microsomes at a 30μM concentration equivalent to the Cmax of omeprazole and rabeprazole, rabeprazole significantly prolongs the metabolic clearance of palbociclib, whereas omeprazole affects the ribociclib CYP3A4-mediated metabolism. CONCLUSION: Using dynamic models, we determined that proton pump inhibitors such as rabeprazole and omeprazole indeed have the potential to cause clinically significant drug-drug interactions with CDK inhibitors in the treatment of estrogen receptor (ER) positive and HER2-positive breast cancer. As a result, it is suggested to use caution when prescribing proton pump inhibitors to these individuals. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Product Details of 117976-90-6).
Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Product Details of 117976-90-6
