The invention relates to indoles of general formula (I):
wherein R¹ represents a hydrogen atom or a C₁₋₆ alkyl or C₃₋₆ alkenyl group;
R² represents a hydrogen atom, a C₁₋₃ alkyl or C₃₋₆ alkenyl group, an aryl or ar(C₁₋₄)alkylene group, or a C₅₋₇ cycloalkyl group;
R³ represents a hydrogen atom or a C₁₋₃ alkyl group;
R⁴ and R⁵, which may be the same of different, each represents a hydrogen atom or a C₁₋₃alkyl or 2-propenyl group, or R⁴ and R⁵ together form an aralkylidine group;
R⁶ represents a C₁₋₆ alkyl or C₃₋₆alkenyl group and
Alk represents an alkylene chain containing two or three carbons atoms which may be unsubstituted or substituted by not more than two C₁₋₃ alkyl groups, and physiologically acceptable salts and solvates (e.g. hydrates) thereof.
Compounds of general formula (I) are useful in treating conditions associated with cephalic pain, in particular migraine.
