Definitions
- the present invention relates to 4,5,6,7-tetrahydro-thieno[2,3-c]pyridine derivatives, to compositions comprising the compounds, to the use of these compounds as medicaments and their use in therapy, e.g. to their use for treatment of human and animal disorders.
- the invention relates to modulation of the activity of molecules with glucose-6-phosphate recognition units, including glucose-6-phosphatases (G-6-Pases) in in vitro systems, microorganisms, eukaryotic cells, whole animals and human beings, especially in the treatment of diseases related to glucose metabolic pathways.
- G-6-Pases glucose-6-phosphatases
- Glucose is the major energy substrate in mammals and regulation of blood glucose levels within a narrow range seems to be of crucial importance to devoid serious physiological complications as seen in diabetes (DeFronzo, Bonadonna, & Ferrannini. 1992). Blood glucose homeostasis is maintained by dietary intake of carbohydrates, the uptake of glucose by peripheral tissues and the brain, and storage or release of glucose from the liver. The liver therefore seems to play a major role in the homeostatic regulation of blood glucose levels. Gluconeogenesis and glycogenolysis are the two metabolic pathways from which glucose can be produced in the liver. These pathways are under tight hormonal control. Insulin resistance and insulin deficiency have a substantial impact on glucose production in the liver (Consoli.
- G-6-Pase Glucose-6-phosphatase catalyses the terminal step in the above mentioned pathways by converting glucose-6-phosphate (G-6- P) to glucose, and is largely situated in the liver, with some expression in the kidney after prolonged fasting.
- the G-6-Pase is a multicomponent system comprising of the G-6-Pase catalytic enzyme with its active site located at the luminal site of the endoplasmic reticulum (microsomal fraction), a specific transporter T1 which mediates entry of G-6-P into the luminal compartment, and transporter T2 and T3 which mediates export to the cytosol of inorganic phosphate and glucose, respectively (Nordlie, Bode, & Foster. 1993; Sukalski & Nordlie. 1989). It has been shown that the rate of hydrolysis of G-6-P and the hepatic glucose output were increased under diabetic conditions (Lyall, Grant, Scott, & Burchell.
- G-6-Pase catalytic enzyme protein ArArgaud, Zhang, Pan, Maitra, Pilkis, & Lange. 1996; Burchell & Cain. 1985. This makes G-6-Pase enzyme a potential target in control of excess glucose production seen in diabetes.

- injectable solutions or suspensions preferably aqueous solutions with the active compound dissolved in polyhydroxylated castor oil. Tablets, dragees, or capsules having talc and/or a carbohydrate carrier or binder or the like are particularly suitable for oral application.
- a typical tablet appropriate for use in this method, may be prepared by conventional tabletting techniques and contains:
- Active compound (as free compound or salt thereof) 5.0 mg
- the compounds of the invention may be administered to a mammal in need of such treatment, prevention, elimination, alleviation or amelioration of various diseases as mentioned above and especially of diseases of the endocrinological system such as hyperinsuiinaemia and diabetes.
- mammals include both domestic animals, e.g. household pets, and non-domestic animals such as wildlife.
- the mammal is a human.
- Hydrogen oxalate It was prepared by neutralisation of solution of above base in diethyl ether with a solution of oxalic acid dihydrate in acetone. Hydrogen oxalate was contaminated with hydrogen oxalate of 2-(3-thienyl)ethylamine. A suspension of the mixture was repeatedly boiled with water and filtrated. This afforded, after drying, pure 4-(4- trifluoromethoxyphenyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine, hydrogen oxalate 2.5 g (8 %), m.p. 190-195 °C.
- 2-(3-Thienyl)ethanamine was prepared analogous to the method described by M. Cardellini et al. Thiophene-3-carboxaldehyde (15.0 g), nitromethane (9.79 g) and sodium methoxide ( 2 M, 71.25 ml) were mixed in methanol ( dry , 50 ml).
- 2-(3-Thienyl)ethanamine (3 g) was treated with 4-methoxycyclohexanecarboxylic acid ( cis/trans mixture , 3.73 g) , HOBT ( 3.18 g) , and EDAC (6.78 g) in DMF (180 ml). The mixture is stirred overnight , evaporated to dryness. The resulting oil is redissolved in methylene chloride ( 100 ml) and extracted with NaOH (2 M, 100 ml). The organic phase was separated and further extracted consecutively with sat. Saline (100 ml) , HCI (0.1 M, 100 ml), NaOH (0.5 M, 100 ml) .
- Tetrahydro-3-furoic acid (2-thiophen-3-yl-ethyl)-amide(3.35 g) ,POCI3 (4.06 ml) were reacted in toluene (150 ml) exactly as described in example 4.
- HPLC-MS analyses were performed on a PE Sciex API 100 LC/MS System using a WatersTM 3 mm x 150 mm 3.5 ⁇ C-18 Symmetry column and positive ionspray with a flow rate at 20 ⁇ L/minute.
