A series of 3-substituted-benzofuran-2-carboxylic esters was synthesized and evaluated for biological activity as ischemic cell death inhibitors in H9c2 cells and rat primary cardiac myocytes under conditions of oxygen and glucose deprivation. The introduction of a sulfur atom at the three-position substituent of the benzofuran ring markedly improved ischemic cell death inhibitory potency. In particular, 3-[2-(4-nitro-phenylsulfanyl)-acetylamino]-benzofuran-2-carboxylic acid ester (10) (EC(50)=0.532 μM, cell death=6.18%) and 4-chloro-3-[3-(pyridin-2-ylsulfanyl)-propionylamino]-benzofuran-2-carboxylic ester (18) (EC(50)=0.557 μM, cell death=7.02%) were shown to be the most potent in this series of benzofuran analogs.

Enzymes which catalyze the hydrolysis of carboxylic acid esters with the formation of an alcohol and a carboxylic acid anion.
Salts or esters of carbamic acid, H2NC(=O)OH, or of N-substituted carbamic acids: R2NC(=O)OR', (R' = hydrocarbyl or a cation). The esters are often called URETHANE or urethan, a usage that is strictly correct only for the ethyl esters. (From IUPAC [Internet].
