Abstract: Compounds having the formula (I) wherein R.sub.1 and R.sub.2 are a hydrogen atom, an alkyl group or a hydroxy group, or else R.sub.1 and R.sub.2 form together a bivalent ethylene or trimethylene radical; R.sub.3 is a halogen atom, an alkyl group, an alkoxy group, a mono- or polyhydroxylated alkyl group, an amino group, a mono- or di-alkyl amino group, an acetamido or sulfonamido group; R.sub.1 is a hydroxy group, a mono- or polyhydroxylated alkyl group, an amino group, a mono- or dialkyl amino group, an acetamido or sulfonamido group; R.sub.4 being in the position 3, 4 or 5 and A is a bridge having from 1 to 3 links selected among the groups having the formula (II), --NH--,--N.dbd.--O-- and --S--. R.sub.5 represents an hydrogen atom, an alkyl group, a hydroxy group or an alkoxy group as well as the addition salts thereof with pharmaceutically acceptable acids. Said compound may be used in therapeutical treatment as antihypertensive agents, particularly in the ocular field.
