ABSTRACT The present invention relates to compounds of formula I: (I) or a pharmaceutically acceptable acid addition salt thereof, where; X is C(R3c= or N=; R1 is C2-C6 alkyl, substituted C2-C6 alkyl, C3-C7 cycloalkyl, substituted C3-C7 cycloalkyl, phenyl, substituted phenyl, heterocycle, or substituted heterocycle; R2 is hydrogen, C1-C3 n-alkyl, C3-C6 cycloalkyl-C1-C3 alkyl, or a group of formula II (II) provided that when R1 is C2-C6 alkyl or substituted C2-C6 alkyl, R2 is hydrogen or methyl; R3a, R3b, and, when X is C(R3c)=, R3c, are each independently hydrogen, fluoro, or methyl, provided that no more than one of R3a, R3b, and R3c may be other than hydrogen; R4 is hydrogen or C1-C3 alkyl; R5 is hydrogen, C1-C3 alkyl, or C3-C6 cycloalkylcarbonyl, provided that when R3a is other than hydrogen, R5 is hydrogen; R6 is hydrogen or C1-C6 alkyl; and n is an integer from 1 to 6 inclusively. The compounds of the present invention are useful for activating 5-HT1F receptors, inhibiting neuronal protein extravasation, and for the treatment or prevention of migraine in a mammal.
本发明涉及以下化合物的公式I:(I)或其药学上可接受的酸加盐,其中;X为C(R3c=或N=;R1为C2-C6烷基,取代的C2-C6烷基,C3-C7环烷基,取代的C3-C7环烷基,苯基,取代的苯基,杂环烷基,或取代的杂环烷基;R2为氢,C1-C3正烷基,C3-C6环烷基-C1-C3烷基,或公式II的基团(II),但当R1为C2-C6烷基或取代的C2-C6烷基时,R2为氢或甲基;R3a,R3b,和当X为C(R3c)=时,R3c,各自独立地为氢,氟,或甲基,但R3a,R3b,和R3c中的最多一个可能不是氢;R4为氢或C1-C3烷基;R5为氢,C1-C3烷基,或C3-C6环烷基甲酰,但当R3a不是氢时,R5为氢;R6为氢或C1-C6烷基;n为1到6的整数(包括1和6)。本发明的化合物可用于激活5-HT1F受体,抑制神经蛋白外渗,以及用于治疗或预防哺乳动物的偏头痛。
