inhibitors of guinea pig liver transglutaminase. The most effective inhibitors evaluated can be sorted into two subclasses: substituted cinnamoyl benzotriazolyl amides and the 3-(substituted cinnamoyl)pyridines, referred to more commonly as azachalcones. Kinetic evaluation of both of these subclasses revealed that they display reversible inhibition and are competitive with acyldonor TGase substrates at IC50
A facile and diverse synthesis of coumarin substituted spirooxindole and dispiro oxindole-pyrrolizidine/pyrrolothiazole/pyrrolidine derivatives via 1, 3-dipolar cycloaddition
A diverse series of coumarin substituted spirooxindole and dispirooxindole-pyrrolizidine/pyrrolothiazole/pyrrolidinederivatives have been obtained via azomethineylide specific three-component 1,3-dipolarcycloadditionreaction. This protocol features include operational simplicity, mild reaction conditions, high yields and a broad substrate scope.
in vitro and in vivo anti-inflammatorypotential. Amongst the synthesized compounds, compounds 7a, 7d and 7f exhibited significant in vitro anti-inflammatory activity as compared to the standard etoricoxib. Keeping this in mind, in vivo investigations were carried out via carrageenan induced inflammation and aceticacid induced writhing models in male Wistar rats and compound 7a was found to possess

photodehydrogenation reactions vary in a significant range according to the structure of pyrazoline. The data correlate with ionization potentials of pyrazolines available from DFT quantum chemical calculations. These results are discussed in terms of proposed scheme of mechanism of pyrazolines photodehydrogenation assuming formation of ion‐radical and ion intermediates.
