Abstract:
본 발명은 화학식 1 내지 7로 표시되는 2-에톡시프로피온산 유도체 또는 이의 약학적으로 허용가능한 염, 이의 제조방법 및 이를 유효성분으로 함유하는 당뇨병 예방 및 치료제에 관한 것으로, 본 발명에 의한 2-에톡시프로피온산 유도체 또는 이의 약학적으로 허용가능한 염은 PPAR(peroxisome proliferator-activated receptor) α 또는 γ 수용체에 이중으로 작용함으로써, 더욱 효과적으로 당뇨병을 예방 및 치료하는 데 유용하게 사용할 수 있다.
Abstract:
A 2-ethoxypropionic acid derivative or pharmaceutically acceptable salt thereof is provided to be useful for preventing and treating diabetes more effectively by dually acting on a peroxisome proliferator-activated receptor alpha or gamma. A method of reaction formula (1) for preparing 2-ethoxypropionic acid derivatives includes the steps of: (i) coupling a compound of the formula 8 with a compound of the formula 9a in an organic solvent in the presence of a base to prepare a compound of the formula 10; (ii) reducing the compound of the formula 10 to prepare a compound of the formula 11; and (ii) subjecting the compound of the formula 11 and isocyanate(R3-NH-CH=O) or isothiocyanate(R3-NH-CH=S) to a coupling reaction and a hydrolysis reaction in the presence of a base, followed by thereto adding an acid to prepare a compound of the formula 1 through acidification.
