摘要:
A biguanide derivative compound with N4-N5 substitution, which is represented by Formula 1, or a pharmaceutically acceptable salt thereof, a method of preparing the same, and a pharmaceutical composition containing the same as an active ingredient are provided. The biguanide derivative may exhibit excellent effect on activation of AMPK and inhibition of cancer cell proliferation in a low dose, compared with conventional drugs, and thus, may be useful to treat diabetes mellitus, obesity, hyperlipidemia, hypercholesterolemia, fatty liver, coronary artery disease, osteoporosis, polycystic ovarian syndrome, metabolic syndrome, cancer, etc.
摘要:
A process of reacting a compound having an NH group with a thiocyanate, a cyanamide, a nitrile, or an ester in the presence of a silylating agent to thereby obtain the corresponding nitrogen-containing addition or substitution product. This process enables direct and efficient synthesis of nitrogen compounds such as isothioureas, guanidines, amidines, and amides, and is universally applicable and suitable for mass production.
摘要:
A synthesis method which comprises reacting NH group-containing compounds with thiocyanates, cyanamides, nitriles or esters in the presence of a silylating agent to synthesize the corresponding nitrogen-containing addition or substitution products. This method not only enables the direct and efficient synthesis of nitrogen-containing compounds including isothioureas, guanidines, amidines and amides, but it also has a wide range of applications and is suitable for large-scale synthesis.

Beschrieben wird ein Verfahren zur Herstellung von Guanidinderivaten, insbesondere Kreatin, bei dem ein Cyanamidderivat und ein primäres oder sekundäres Amin in Gegenwart von Kristallen des Guanidinderivates kontinuierlich vereinigt werden.
摘要:
A process for preparing guanidino-functional, free radically polymerizable compounds comprises (a) combining (1) an amine compound comprising (i) at least one primary aliphatic amino group and (ii) at least one secondary aliphatic amino group, primary aromatic amino group, or secondary aromatic amino group, and (2) a guanylating agent; (b) allowing or inducing reaction of the amine compound and the guanylating agent to form a guanylated amine compound; (c) combining (1) the guanylated amine compound, and (2) a reactive monomer comprising (i) at least one ethylenically unsaturated group and (ii) at least one group that is reactive with an amino group; and (d) allowing or inducing reaction of the guanylated amine compound and the reactive monomer to form a guanidino-functional, free radically polymerizable compound.
摘要:
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.
