Problems solved by technology

As a result, the pills are too large for patients to swallow
In addition, since the single extended-release tablets currently on the market contain only about 750 mg of metformin, two or more extended-release tablets are required
In addition, phenformin, which belongs to the same biguanide class, has been completely banned since the 1970s due to serious side effects such as lactic acidosis

Embodiment 1

[0093] Embodiment 1: the synthesis of N1-piperidine cyanoguanidine

[0094] Piperidine (92.8ml, 0.940mol) was dissolved in butanol (300ml), concentrated hydrochloric acid (81.7ml, 0.940mol) was added to the resulting solution and stirred at 0°C for 30 minutes. Sodium dicyanamide (92.0 g, 1.03 mol) was added to the resulting mixed solution, and the resulting reaction mixture was stirred under reflux for 24 hours. After confirming that the reaction was finished, the reaction mixture was filtered, and the sodium chloride formed in the filtration was removed, and the filtrate was concentrated under reduced pressure. Distilled water (100 ml) was added to the concentrate, followed by stirring at room temperature for 1 hour. The formed solid was filtered, the filter cake was washed with distilled water (2×20 ml), and then dried under reduced pressure to obtain the target compound as a white solid (93.3 g, 65%).

Embodiment 2

[0096] Embodiment 2: the synthesis of N1-azetidine cyanoguanidine

[0097]

[0098] The title compound (1.13 g, 52%) was prepared as a white solid as described in Example 1, but substituting azetidine for the piperidine used in Example 1.

Embodiment 3

[0100] Embodiment 3: N1-pyrrolidine cyanidine

[0101]

[0102] The title compound (24.5 g, 63%) was prepared as a white solid as described in Example 1, but substituting pyrrolidine for the piperidine used in Example 1.

Abstract

An N1-cyclic amine-N5-substituted phenyl biguanide derivative of Formula 1 or a pharmaceutically acceptable salt thereof, a method of manufacturing the same, and a pharmaceutical composition including the biguanide derivative or the pharmaceutically acceptable salt thereof as an active ingredient are provided. The biguanide derivatives have an effect of inhibiting cancer cell proliferation and also exhibit anticancer activity including inhibition of cancer metastasis and cancer recurrence, because they are effective in activating AMPK, which is associated with the control of energy metabolism, even when administered in a small dose compared with conventional drugs.; Also, the biguanide derivatives are highly effective at lowering blood glucose and lipid concentration by AMPK activation, thus they may be effectively used to treat diabetes mellitus, obesity, hyperlipemia, hypercholesterolemia, fatty liver, coronary artery disease, osteoporosis, polycystic ovary syndrome and metabolic syndrome.

Description

technical field [0001] The present invention relates to: an N1-cyclic amine-N5-substituted phenyl biguanide derivative, which can inhibit the proliferation of cancer cells, cancer metastasis and cancer recurrence, and also inhibit diabetes and New town metabolic disease has excellent curative effect even if its dose is less than that of conventional medicine; a method for preparing the derivative; and a drug combination containing the N1-cycloamine-N5-substituted phenylbiguanide derivative as an active ingredient thing. Background technique [0002] AMPK is an enzyme whose function is to control metabolic pathways to maintain a balance between nutrient supply and energy demand, and thereby maintain energy balance in cells and throughout the body. In the state of hypoxemia or hypoglycemia, the ratio of intracellular AMP / ATP increases and AMPK is activated. Activated AMPK causes fatty acid oxidation to generate greater amounts of ATP and inhibits anabolism that requires ATP ...
