The present invention relates to indole derivatives represented by formula (I):
wherein R1 and R2 independently represent hydrogen, lower alkyl, -(CH2)n-OR6 (wherein R6 represents hydrogen or lower alkyl, and n is an integer of 1 to 6), or
(wherein R7 and R8 independently represent hydrogen or lower alkyl, or R7 and R8 are combined together with the adjacent nitrogen atom to form a substituted or unsubstituted alicyclic heterocyclic group, and m represents an integer of 2 to 6), R3 represents hydrogen, lower alkyl, or
(wherein R9 and R10 independently represent hydrogen or lower alkyl, or R9 and R10 are combined together with the adjacent nitrogen atom to form a substituted or unsubstituted alicyclic heterocyclic group, and p represents an integer of 2 to 6), R4 and R5 independently represent hydrogen, lower alkyl, alicyclic alkyl, substituted or unsubstituted aryl, or a substituted or unsubstituted heterocyclic group, or R4 and R5 are combined together with the adjacent nitrogen atom to form a substituted or unsubstituted alicyclic heterocyclic group, or pharmaceutically acceptable salts thereof.
