Recording simultaneously in vitro the changes of endoluminal pressure (index of circular muscle activity) and isometric tension (index of longitudinal muscle activity), we examined the mechanisms responsible for the apamin-sensitive relaxant and contractile responses induced by protease-activated receptor (PAR)-1 and PAR-2 activating peptides, SFLLRN-NH2 and SLIGRL-NH2, respectively, in rat col...

In the presence of strong bases (NaH, DBU, KOH), ethyl 4-chloromethyl-6-methyl-2-oxo1,2,3,4-tetrahydropyrimidine-5-carboxylate and 4-mesyloxymethyl-6-methyl-5-tosyl-1,2,3,4tetrahydropyrimidin-2-one are transformed into novel tricyclic compounds, diethyl 9-methyl-5methylene-3,11-dioxo-2,3,4,5,6a,7,10,11-octahydro-1,6-methano[1,3]diazepino[1,7-e][1,3,5]triazocine-6,8(1H)-dicarboxylate and 9-methy...

The title compound, C(10)H(9)NO(3), was synthesized by the condensation reaction of isatin (systematic name 1H-indole-2,3-dione) with glycol in presence of p-toluene-sulfonic acid. The indol-2-one ring system is essentially planar [N-C-C-C torsion angle = 3.1 (2)°], and the 1,3-dioxolane ring is slightly distorted. The crystal structure exhibits inter-molecular N-H⋯O hydrogen bonds.
