19 Dec 1997TL;DR: In this article, the methods for treating inflammnatory pathologies are disclosed, particularly, the methods utilize pharmaceutical compositions containing certain compounds having an anti-inflanumatory and anti-oxidant moiety covalently linked by thiol or sulfoxide or sulfone bond.
Abstract: Methods for treating inflammnatory pathologies are disclosed. Particularly, the methods utilize pharmaceutical compositions containing certain compounds having an anti-inflanumatory and anti-oxidant moiety covalently linked by thiol or sulfoxide or sulfone bond. The compounds are useflil in preventing and treating inflammatory disorders through several mechanisms.

TL;DR: In this paper, photochromic spiro[indoline-benzopyrans] containing 4,5-diphenyloxazolyl group at position 8 of the benzopyran fragment have been obtained.
Abstract: Photochromic spiro[indoline-benzopyrans] containing 4,5-diphenyloxazolyl group at position 8 of the benzopyran fragment have been obtained. New diphenyloxazolyl-substituted spiropyrans manifest considerably higher thermal stability of the merocyanine isomers than their naphthopyran analogs.
