The present invention relates as new industrial product to a derivative of pyrano-indole chosen from the group constituted by: (i) the pyrano[2,3-g]indoles of general formula: ##STR1## in which: X represents a group ##STR2## (where R is a lower alkyl group, OH, lower alkoxy, tosyloxy, NH.sub.2) or >CH--NR'R" (where R' and R", which are identical or different, each represent H or a lower alkyl); R.sub.1 represents an atom of hydrogen, a lower alkyl group, or COY.sub.1 (where Y.sub.1 is a lower alkyl group, an amino acid group CH.sub.2 CH(COOH) NH.sub.2 or an aminoalkylene group --(CH.sub.2).sub.n --NR'R" in which n is a whole number between 1 and 4 and R' and R" are defined as hereinabove); R.sub.2 represents an atom of hydrogen, or a COY.sub.2 group (where Y.sub.2 is OH or lower alkoxy; R.sub.3 represents an atom of hydrogen, an atom of halogen, a CHO group, lower alkyl, CF.sub.3, (CH.sub.2).sub.n NR'R" or CO--CONR'R" (where n, R' and R" are defined as hereinabove, and R.sub.4 represents an atom of hydrogen, an atom of halogen, an OH group, lower alkyl, lower alkoxy, CF.sub.3 or NR'R" (where R' and R" are defined as hereinabove); (ii) the pyrano[3,2-f]indoles of general formula: ##STR3## where X, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are defined as hereinabove; and (iii) their acid addition salts. The invention also relates to the process for preparing this derivative and to its application in therapeutics.
