The present invention relates as new industrial product to a derivative of pyrano-indole chosen from the group constituted by:

Pyrano[2,3-g]indoles useful as anti-ulcerous, anti-inflammatory and

Pyrano-indoles

The present invention relates to the benzoyl- and .alpha.-hydroxybenzyl-phenyl-oside derivatives of general formula: ##STR1## [in which Z is CO or CHOH, X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5, which are identical or different, each represent an atom of hydrogen, an atom of halogen, an alkyl group with 1 to 4 carbon atoms, an alkyl group with 1 to 4 carbon atoms substituted by one or more atoms of halogen, an OH group, an alkoxy group with 1 to 4 carbon atoms, an alkoxy group with 1 to 4 carbon atoms, substituted by one or more atoms of halogen, a nitro group, a cyano group, a thiocyano group, an isothiocyano group, a NR'R' group (where R' and R', identical or different, each represent an atom of hydrogen or an alkyl group with 1 to 4 carbon atoms) X.sub.1 being able, in addition, to represent an --NH--CS--O--CH.sub.3 group or an --O--C(CH.sub.3).sub.2 CO.sub.2 --R'' group (where R'' is an alkyl group with 1 to 4 carbon atoms and, preferably, an isopropyl group); and R represents a radical ose (the hydroxyl and amine functions of the radical ose being able to be substituted by acyl, alkyl or sulfate groups)], and to their diastereoisomers. It also relates to the method for preparing these derivatives and to their application in therapeutics.
