Indole derivatives

Abstract

Disclosed are indole derivatives of formula (I) ##STR1## wherein X and Y each independently represent H or --CH.sub.2 CH.sub.2 R; R represents pyridyl or substituted amino of NR.sub.1 R.sub.2 ; R.sub.1 represents H or C.sub.1 -C.sub.6 alkyl; R.sub.2 represents 2-(3-indolyl)ethyl or aralkyl; or R.sub.1 and R.sub.2 together with the nitrogen atom to which they are attached may form an N-containing 5 to 6 membered hetero ring, an N, O-containing hetero ring, which hetero ring may be fused with benzene; n is an integer of 4 to 8; with the proviso that X and Y both do not represent H or piperizinoethyl when n is 4, or pharmaceuticaly acceptable acid addition salts thereof. They are useful as an antiulcer agent.

Dependencies are inferred from the claim text.
