The present invention provides Indole derivatives represented by the formula (I)
wherein R¹, R² and R³ independently represent hydrogen or lower alkyl;
R⁴ represents hydrogen, lower alkyl or cycloalkyl;
R⁵ represents hydrogen, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkenyl, -CHR⁷R⁸ where R⁷ and R⁸ independently represent hydrogen, alkyl, alkenyl, alkynyl, substituted or unsubstituted cycloalkyl, -(CH₂)mOR⁹ (wherein m is an integer of 1 - 3 and R⁹ is lower alkyl), substituted or unsubstituted aryl, substituted or unsubstituted pyridyl, substituted or unsubstituted furyl, or substituted or unsubstituted thienyl],
(wherein p is an integer of 1 - 3) or
(wherein Y is CH₂, O, S, CH₂-CH₂, CH=C, CH₂-O or CH₂-S);
R⁶ represents hydrogen, lower alkyl or lower alkoxy or halogen;
X represents O or S(O)q (wherein q is an integer of 0-2);
and n represents an integer of 1-6} or pharmaceutically acceptable salts thereof.
