The present invention relates to substituted furo[3,2-b]pyridine compounds of formula I:
or a pharmaceutical acid addition salt thereof; where;
R is
E—D is C═CH or CH—CH2;
R1 is hydrogen or C1-C4 alkyl;
R2 is hydrogen, halo, hydroxy, —NR3R4, —SR3, —C(O)R3, —C(O)MR3R4, —NR3SO2R5, —NHC(Q)NR3R4, —NHC(O)OR3, or —NR3C(O)R5;
R3, R4, and R5 are independently hydrogen, C1-C4 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, or —(CH2)naryl; or R3 and R4 combine, together with the nitrogen to which they are attached, form a pyrrolidine, piperidine, piperazine, 4-substituted piperazine, morpholine, or thiomorpholine ring;
n is 0, 1, 2, 3, 4, 5, or 6; and
Q is O or S.
The present invention further relates to pharmaceutical. formulations containing compounds formula I and to the use of compounds of formula I for activating 5-HT1F receptors, inhibiting neuronal protein extravasation, and treating and/or preventing migraine in a mammal.
本发明涉及以下式I的取代呋喃[3,2-b]吡啶化合物或其药用酸盐;其中;R为E—D为C═CH或CH—CH2;R1为氢或C1-C4烷基;R2为氢、卤素、羟基、—NR3R4、—SR3、—C(O)R3、—C(O)MR3R4、—NR3SO2R5、—NHC(Q)NR3R4、—NHC(O)OR3或—NR3C(O)R5;R3、R4和R5独立地为氢、C1-C4烷基、C2-C6烯基、C2-C6炔基或—(CH2)n芳基;或R3和R4结合,与它们连接的氮一起形成吡咯烷、哌咯烷、哌嗪、4-取代哌嗪、吗啉或硫代吗啉环;n为0、1、2、3、4、5或6;Q为O或S。本发明还涉及含有式I化合物的制剂以及利用式I化合物激活5-HT1F受体、抑制神经蛋白外渗,并在哺乳动物中治疗和/或预防偏头痛。
