Β-aminoalcohol compounds substituted with phenyltetrazole derivatives}

The present invention relates to a β-aminoalcohol compound substituted with a phenyltetrazole derivative, and more particularly, to a β-aminoalcohol compound substituted with a phenyltetrazole derivative, pharmaceutically acceptable salts thereof and a method of preparing the same. And pharmaceutical compositions containing the compounds and their salts as active ingredients.

In general, the treatment of type 2 diabetes and obesity has been recognized as an important treatment for diet and exercise for weight loss and improving insulin sensitivity, but these patients have a problem that it is difficult for patients to continue to practice. There are not many drugs that can effectively treat type diabetes or obesity.

Since the protein sequence of the β ₃ -adrenergic receptor has been revealed, it has been found that the β ₃ -adrenergic receptor can be stimulated to control weight loss as well as hyperglycemia. These β ₃ -adrenergic receptors are distributed in white and brown adipose cells and are known to act to help break down fat or help fever. In particular, the anti-inflammatory agents of β ₃ -adrenergic receptors are lipolytic, fever and secondary. It has been shown to have an effect on blood sugar control in experimental animals showing symptoms of type diabetes.

However, the above β ₃ -adrenergic receptors are inferior in efficacy and selectivity, so there is still a need for the development of excellent anti-inflammatory agents. Further, the β ₃ - is that it stimulates the other β- receptors other than the adrenoceptor-induced side effects - The main disadvantage of agonists for the β ₃ adrenergic receptors.

Initially developed β ₃ -adrenergic receptors are representative of phenylethanolamine derivatives (see US Pat. No. 4,478,849 and US Pat. No. 4,396,672). , 4,999,377, 5,017,619, European Patent 427480, European Patent 455006).

On the other hand, efforts have been made to develop compounds having a selective antagonistic action on the β ₃ -adrenergic receptor through modification of various kinds of binary ring compounds (Japanese Patent No. 98007647, Japanese Patent No. 98158233, International Patent) See Japanese Patent Application Publication No. 9832742, European Patent No. 822185, and Japanese Patent No. 98007647), in particular, β-aminoalcohol derivatives having pyrazole derivatives are known to show excellent efficacy (see European Patent No. 0921120).

Accordingly, the present invention synthesized β-aminoalcohol compounds substituted with phenyltetrazole derivatives, and found that these compounds bind to the β ₃ -adrenergic receptor to reduce blood sugar and weight, thereby completing the present invention.

Example 42 Preparation of 2-1-methyl-3- [4- ( 2H -tetrazol-5-yl) phenyl] propylamino-1-phenyl-1-ethanol

2-amino-1-phenyl-1-ethanol (136 mg, 1 mmol), 4- [4- (2H-1,2,3,4-tetrazol-5-yl) phenyl] -2-butanone (0.23 mg, 1.05 mmol) and 1.6 g of molecular sieve were added to benzene (12 mL) and refluxed for 19 hours. After filtration, the solvent was removed under reduced pressure, and platinum (IV) oxide (23 mg, 10 mol%) was added in anhydrous methanol (20 mL) solvent, followed by reaction under hydrogen (70 psi) for 4 hours, followed by filtration and removal of the solvent under reduced pressure. Next, the target compound was separated using column chromatography (dichloromethane: methanol = 20: 1). 2-1-methyl-3- [4- (2H-1,2,3,4-tetrazol-5-yl) phenyl] propylamino-1-phenyl-1-ethanol (0.17 g, 29%) was obtained. .

Example 89: Blood sugar strengthening and weight loss effect

In Experimental Example 87, some of the compounds having strong binding to β ₃ -adrenergic receptors were administered to experimental rats showing diabetes and obesity, respectively, and the changes in blood glucose and weight were shown in FIGS. 1 and 2.

The drug was prepared by dissolving the compounds of Examples 46, 57, 65, or 66 and 81 in 0.25% w / v methyl cellulose, and 5 mg / kg / day after the preparation of the drug by dissolving BRL 35135 as a control. The dose was administered orally for 5 days. Blood was collected from the fundus vein on day 1, 3, and 5 (10-15 mg). Drug administration was performed at 10 am and blood collection was performed at 2 pm. The collected blood was immediately shaken with ice at 1: 5 with physiological saline containing 2.5 mg / ml of sodium fluoride and 25 sodium heparin on ice, followed by centrifugation at room temperature. Using the supernatant, blood glucose was measured by Glucose Analyzer 2 (Glucose Analyzer, Beckman Instruments, Portville, Calif.) And insulin was measured by Rat Ultrasensitive Insulin ELISA Kit (ALPCO, Windham, NH). In this process, the weight change of the rats was observed for 5 days.

As can be seen in FIG. 1, the blood glucose level gradually increased in the solvent group, whereas the blood glucose level rapidly decreased when the drug containing the compound of the control compound BRL 35135 was administered. In addition, when the drug containing the compound of Example 81 was administered, a slight increase in blood glucose was observed on day 1, but thereafter, the blood glucose level was rapidly decreased to a minimum blood glucose level similar to BRL 35135 on day 5. In Example 57, the blood glucose level was rapidly decreased from day 1. Since these compounds have an excellent hypoglycemic effect, it has been confirmed that they can be usefully used for the treatment of endocrine diseases including diabetes, obesity, hyperinsulinemia.
