Compounds are disclosed of formula (I) ##STR1## wherein R.sub.1 represents CHO, COR.sub.8, CO.sub.2 R.sub.8, CONR.sub.9 R.sub.10, CSNR.sub.9 R.sub.10 or SO.sub.2 NR.sub.9 R.sub.10, where R.sub.8 represents alkyl, cycloalkyl, aryl or aralkyl, R.sub.9 represents hydrogen or alkyl, and R.sub.10 represents hydrogen or alkyl, cycloalkyl, aryl or aralkyl; R.sub.2, R.sub.3, R.sub.4, R.sub.6 and R.sub.7 each independently represents hydrogen or C.sub.1-3 alkyl; R.sub.5 represents hydrogen, or alkyl, cycloalkyl, alkenyl or aralkyl, or R.sub.4 and R.sub.5 together form an aralkylidene group or R.sub.4 and R.sub.5 together with the attached nitrogen atom form a saturated monocyclic 5- to 7-membered ring; and Alk represents C.sub.2-3 alkylene chain optionally substituted by not more than two C.sub.1-3 alkyl groups; and physiologically acceptable salts and solvates thereof. The compounds are potentially useful for the treatment of migraine and may be formulated as pharmaceutical compositions in conventional manner using pharmaceutically acceptable carriers or excipients. The compounds may be prepared by, for example, reaction of an aminoalkyl indole with an acid of formula R.sub.1 OH or an acylating agent corresponding thereto or with an inorganic cyanate or an organic isocyanate or isothiocyanate in order to introduce the desired R.sub.1 group at the 5-position on the indole nucleus.
公式(I)的化合物被披露,其中R1代表CHO,COR8,CO2R8,CONR9R10,CSNR9R10或SO2NR9R10,其中R8代表烷基,环烷基,芳基或芳基烷基,R9代表氢或烷基,R10代表氢或烷基,环烷基,芳基或芳基烷基; R2,R3,R4,R6和R7各自独立地代表氢或C1-3烷基; R5代表氢,或烷基,环烷基,烯基或芳基烷基,或R4和R5一起形成芳基烷基亚甲基基团,或R4和R5与相连的氮原子一起形成饱和的单环5-至7-成员环; Alk代表C2-3烷基链,可选地被不超过两个C1-3烷基取代;以及其生理上可接受的盐和溶剂。这些化合物可能对偏头痛的治疗有用,并可以使用药学上可接受的载体或赋形剂按照传统方法制成制药组合物。这些化合物可以通过例如,将氨基烷基吲哚与公式R1 OH的酸或相应的酰化剂或与无机氰酸盐或有机异氰酸盐或硫氰酸盐反应来引入所需的R1基于吲哚核上的5位。
