Abstract: Ethynylbiphenyl derivatives of the general formula (I): ##SPC1##in which R represents a chlorine or bromine atom in the 2, 3 or 4 position. These compounds have anti-inflammatory activity.

Abstract: Indane derivatives of general formula (I): ##SPC1##in which:R.sub.1 and R.sub.2 represent a hydrogen atom, a lower alkyl group, preferably containing 1 to 6 and particularly 1 to 4 carbon atoms, or an arylalkyl group, or together form a cycloalkyl ring containing 3-6 carbon atoms; R.sub.3 is a hydrogen atom or a lower alkyl preferably containing 1 to 6 and particularly 1 to 4 carbon atoms; R.sub.4 represents the group --NR.sub.5 R.sub.6 in which R.sub.5 and R.sub.6 may be the same or different and each represent a hydrogen atom, a carbamoyl group or a lower alkyl radical preferably containing 1 to 6 and particularly 1 to 4 carbon atoms which may optionally be substituted by amino, alkylamino, dialkylamino, hydroxy, aryl or aroyl groups which aroyl groups may be substituted; or in which R.sub.5 and R.sub.6 may be joined to form a ring optionally containing other hetero atoms; and non-toxic pharmaceutically acceptable salts and esters thereof.
