Some novel α,β-unsaturated aromatic sulfone analogs (5a–5m) and their Tempol conjugates (6a–6e) have been synthetically prepared, characterized and evaluated for their radioprotective activity under γ-ray radiation. The Tempol conjugates were characterized by X-ray single crystal diffraction. In vitro studies showed that 5a, 5b and 6b had superior activities to Ex-Rad pre-treated before 5 Gy irradiation
A variety of (1,4-phenylene)bis(arylmethanesulfonylpyrroles and pyrazoles) were prepared by the cycloaddition of 1,3-dipolarreagents, tosylmethyl isocyanide and diazomethane to the Michael acceptor, 1,4-bis(E)-2-((arylmethanesulfonyl)vinyl)benzene. All the compounds were evaluated for antioxidant activity. Amongst the tested compounds, one of them displayed excellent radical scavenging activity in
Azole compounds represented by formula I:
wherein ring A is isoxazole and the like, R1 is a substituted or unsubstituted aryl group and the like, R2 is a hydrogen atom and the like, and R3 is a substituted or unsubstituted alkyl group and the like, and pharmaceutically acceptable salts thereof inhibit the physiological activity of lysophosphatidic acid (LPA), and are useful as for the prophylaxis or treatment of diseases in which inhibition of the physiological activity of LPA is useful for the prophylaxis or treatment thereof, such as diseases involving the LPA receptor.
