Abstract: The present invention creates a novel antiangiogenic agent and provides an antitumor agent which shows high safety as compared with conventional antitumor agents, has a sure effect and is able to be administered for a long period. That is, it provides an indole compound represented by the following formula (I), its pharmacologically acceptable salt or hydrates thereof. In the formula, R1 represents hydrogen atom, a halogen atom or cyano group; R2 and R3 are the same as or different from and each represents hydrogen atom, a C1-C4 lower alkyl group or a halogen atom; R4 represents hydrogen atom or a C1-C4 lower alkyl group; and the ring A represents cyanophenyl group, aminosulfonylphenyl group, aminopyridyl group, aminopyrimidyl group, a halopyridyl group or cyanothiophenyl group, provided that the case where all of R1, R2 and R3 are hydrogen atoms, where both R2 and R3 are hydrogen atoms or where the ring A is aminosulfonyl group and both R1 and R2 are halogen atoms is excluded. Further, when the ring A is cyanophenyl group, 2-amino-5-pyridyl group or a 2-halo-5-pyridyl group and R1 is cyano group or a halogen atom, at least one of R2 and R3 should not be a hydrogen atom.
