inhibitors of leukotrienebiosynthesis in isolated human polymorphonuclear leukocytes. We show that the 2,3-dihydro-5-benzofuranol ring system, although not a potent inhibitor of leukotrienebiosynthesis in itself, can provide a useful template for the design of antioxidant-based inhibitors of leukotrienebiosynthesis. Furthermore, within a structural class the potency of a given analogue can be predicted

The present invention relates to compounds of formula I, in which at least one of R5, R6 and R7 is SR12, S(O)R12 or S(O)2R12 group where R12 is a C1-6haloalkyl group, that act, as chemical uncouplers. Compounds of the invention are useful in the treatment, including prevention, of obesity, diabetes and a number of diseases or conditions associated therewith.
2,3-Dihydrobenzofuran derivatives of general formula (1):
wherein R1 represents a hydrogen atom or an acyl group; R2, R3 and R4 represent a hydrogen atom, a lower alkyl group or a lower alkenyl group; R5 and R6 represent a hydrogen atom or an optionally substituted alkyl group, or R5 and R6 combine to form a cycloalkyl group or a saturated heterocyclic group containing one or more oxygen atoms or alkyl-substituted nitrogen atoms, provided that R2 and R3 can not simultaneously represent a t-butyl group, or optically active isomers or pharmaceutically acceptable salts thereof are useful as therapeutic or prophylactic agents for various renal diseases and as organ preservatives.
