Evaluation of gender difference in pharmacokinetics of Candesartan cilexetil in the fasted state by RP-HPLC: A single dose comparative study was written by Nawaz, Hafiz Awais;Masood, Muhammad Irfan;Abbas, Matecn;Usman, Muhammad;Abdul, Muqeet Khan;Rasheed, Huma;Riffat, Sualeha. And the article was included in Pakistan Journal of Pharmaceutical Sciences in 2019.Application In Synthesis of 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate This article mentions the following:
To compare the pharmacokinetics of candesartan cilexetil in healthy male and female volunteers in order to identify possible influence of gender and to improve therapeutic outcomes, an HPLC method for the quantification of candesartan cilexetil was developed and validated. Total of 16 volunteers (8 male and 8 female) were registered. Candesartan cilexetil 16 mg was administered orally to all the volunteers and blood samples were collected at different time intervals between 0-72 h. Plasma was separated and analyzed by HPLC method. Pharmacokinetic parameters were calculated by using APO software MW/PHARM version 3.02 and compared in male and female volunteers. The developed HPLC method fulfils the criteria for linearity, accuracy and precision described in EMA guideline. The values for absorption rate constant (Ka), maximum plasma concentration (Cmax), volume of distribution (Vd) and Clearance (CL) were similar in male and female volunteers. No influence of gender was observed on overall pharmaco kinetics of candesartan cilexetil. Therefore, no need for dose optimization while administering candesartan cilexetil in male and female patients was found based on the results of this study. In the experiment, the researchers used many compounds, for example, 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate (cas: 145040-37-5Application In Synthesis of 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate).
1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate (cas: 145040-37-5) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Application In Synthesis of 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate
