[0822]Examples Example 1 Preparation of 5-diethylphosphono-2-furfuraldehyde (1) Step A. At -78°C, a solution of 2-furfuraldehyde diethyl acetal (1 mmol) in THF (tetrahydrofuran) was washed with nBuLi (1 mmol) treatment. After 1 hour, diethyl chlorophosphate (1.2 mmol) was added and the reaction was stirred for 40 minutes. After extraction and evaporation, a brown oil was obtained. Step B. The resulting brown oil was treated with 80% acetic acid at 90°C for 4 hours. After extraction and chromatographic purification, compound 1 was obtained as a clear yellow oil. Alternatively the aldehyde can be prepared from furan as described below. Step C. A solution of furan (1 mmol) in ether was treated with TMEDA (N,N,N',N'-tetramethylethylenediamine) (1 mmol) and nBuLi (2 mmol) at -78°C for 0.5 h. Diethyl chlorophosphate (1.2 mmol) was added to the reaction mixture and stirred for another 1 hour. Extraction and distillation afforded diethyl 2-furanphosphonate as a clear oil. Step D...

Preparation of 4-[(2-(5-phosphono)furyl]thiazole, 4-[2- (6-phosphono)pyridyl]thiazole and 4-[2-(5-phosphono)furyl]selenazole Step A. A solution of compound 2.1 (1 mmol) in ethanol was treated with copper(II) bromide (2.2 mmol) was treated under reflux conditions for 3 hours. The cooled reaction mixture was filtered and the filtrate was evaporated to dryness. The resulting dark oil was purified by chromatography to obtain 5-diethylphosphono-2-[(2- Bromo-4-methyl-1-oxo)pentyl]furan as an orange oil. Step B. Adding 5-diethylphosphono-2-[(2-bromo-4-methyl-1-oxo A solution of pentyl]furan (1 mmol) and thiourea (2 mmol) in ethanol was heated to reflux for 2 hours. The cooled reaction mixture was evaporated to dryness and the resulting yellow foam was...

Abstract

Pharmaceutical compositions containing an FBPase inhibitor and an insulin sensitizer are provided as well as methods for treating diabetes and diseases responding to increased glycemic control, an improvement in insulin sensitivity, a reduction in insulin levels, or an enhancement of insulin secretion.

Description

[0001] Related Application Introduction [0002] This application is a continuation of Provisional Application No. 60 / 114,718, filed December 23, 1998, which is hereby incorporated by reference in its entirety. field of invention [0003] The present invention discloses combination therapy with insulin sensitizers and FBPase inhibitors for the treatment of diabetes mellitus and other diseases that would benefit from controlling blood glucose levels or improving insulin sensitivity, lowering insulin levels or increasing insulin secretion disease. The invention also discloses compositions for said treatment. Background of the invention [0004] Diabetes is one of the most prevalent diseases in the world today. Diabetics have been divided into two categories, Type I or insulin-dependent diabetes mellitus and Type II or non-insulin-dependent diabetes mellitus (NIDDM). NIDDM accounts for approximately 90% of all diabe...
