Abstract

NEW MATERIAL:7-Carboxymethoxy-4-phenylcumarin derivatives of formula I (R<1> to R<3> and R<1>' to R<5>' are H, halogen, lower alkyl, lower alkoxy, di lower alkylamino or lower perfluoroalkyl). EXAMPLE:6-Ethyl-4-(3-isopropyloxyphenyl)cumarin-7-yloxyacetic acid. USE:Showing aldose reduction inhibition, capable of reducing production and accumulation of sorbitol and useful as a preventive and a remedy for diabetic complications. PREPARATION:A 7-hydroxy-4-phenylcumarin derivative of formula II is etherified into a glycolic acid ether to synthesis a compound of formula I. The above- mentioned reaction is normally carried out, e.g. using potassium carbonate and ethyl bromoacetate in acetone.

Aldose is a cause of various complications of diabetes such as retinopathy, Yamanouchi syndrome, neuropathy, and nephropathy, and is known to cause the enzyme that catalyzes the conversion between aldose and polyol, which is the first step in the polyol pathway, which is the metabolic pathway for glucose. It is called reductase,
This enzyme is thought to be the rate-limiting step in the polyol pathway. By inhibiting this aldose reductase and reducing the production and accumulation of nrubitol, it is possible to prevent and treat the aforementioned diabetic complications (R. New Eng, J,) led, ),
