  Chemical and in vitro enzymatic stability of newly synthesized celecoxib lipophilic and hydrophilic amides

  摘要：

  Five celecoxib (CXB) acylamide sodium salts, MP-CXB, Cy-CXB, Bz-CXB, CBz-CXB and FBz-CXB were synthesized and characterized. Two simple, fast and validated RP-HPLC methods were developed for simultaneous quantitative determination of the amides and celecoxib in aqueous and biological samples and LOD and LOQ were <= 13.6 and <= 40 ng/mL, respectively. The solubility and logP(app) of the amides, in relevant media, were determined. The chemical hydrolysis, at 60,70 and 80 degrees C, of MP-CXB was studied at GIT-relevant pH (1.2, 6.8 and 7.4) and of CY-CXB was studied at skin relative pH (5.4 and 7.4). Significant hydrolysis was observed for MP-CXB at pH 1.2 only with half-lives 28.28, 11.64 and 3.53h at 60, 70 and 80 degrees C, respectively, with extrapolated half-lives of 2060 and 443 h at 25 and 37 degrees C, respectively. The hydrolysis of all amides was studied in rat live homogenate and only Cy-CXB was hydrolyzed with half-life of 3.79 h. The hydrolysis of MP-CXB and Cy-CXB was studied in human plasma and neither was hydrolyzed. It is finally suggested that hydrophobic interactions plays a role in the binding of susceptible acylamides to the hepatic hydrolyzing enzyme since only amides with saturated hydrocarbon chains underwent hydrolysis.
