The invention has an object to provide a novel quinoline derivative of the following formula (I) which has no benzyl group in the 5-position and shows hypoglycemic effect, particularly, by oral administration:
in which R1 is hydrogen; an alkyl group of 1-6 carbon atoms, an amino group of the formula of -NR4R5 in which each of R4 and R5 independently is hydrogen, alkyl of 1-6 carbon atoms, phenyl, pyridyl, pyrimidyl or benzoyl; or a phenyl group, a naphthyl group, a cycloalkyl group having 3 to 8 carbon atoms, or a 5 to 8 membered heterocyclic group comprising, as ring-constituting atoms, 1 to 2 nitrogens, oxygens or sulfurs and remaining carbon atoms, each of which may have, as a substituent, alkyl of 1-6 carbon atoms, alkoxy of 1-6 carbon atoms, halogen, hydroxyl, halogenoalkyl of 1-6 carbon atoms, halogenoalkoxy of 1-6 carbon atoms, nitro, amino, phenyl, thienyl, furyl, thiazolyl or pyridyl; Z is O, S, C=O, or CH2; E is S or O; m is an integer of 0 to 4; p is an integer of 0 to 4; q is an integer of 0 to 4; and the double line composed of a broken line and a solid line means a single or double bond.
本发明的目的是提供一种下式(I)的新型喹啉衍生物,该衍生物在5位上没有苄基,特别是通过口服具有降血糖作用:
其中 R1 是氢;1-6 个碳原子的烷基;式为 -NR4R5 的氨基,其中 R4 和 R5 各自独立地是氢、1-6 个碳原子的烷基、苯基、吡啶基、嘧啶基或苯甲酰基;或苯基、萘基、具有 3 至 8 个碳原子的环烷基,或 5 至 8 个成员的杂环基团,其组成环的原子包括 1 至 2 个硝基、氧基或硫基和其余的碳原子、每个杂环基团可具有 1-6 个碳原子的烷基、1-6 个碳原子的烷氧基、卤素、羟基、1-6 个碳原子的卤代烷基、1-6 个碳原子的卤代烷氧基、硝基、氨基、苯基、噻吩基、呋喃基、噻唑基或吡啶基作为取代基;Z 是 O、S、C=O 或 CH2;E 是 S 或 O;m 是 0 至 4 的整数;p 是 0 至 4 的整数;q 是 0 至 4 的整数;由折线和实线组成的双线表示单键或双键。
