| abstract |
The subject of the invention is the products of formula (I): (CF DRAWING IN BOPI) in which: R represents a linear or branched alkyl or alkenyl radical containing 3 or 4 carbon atoms, R1, R2, R3 and R5 are such that: either R1, R2, R3 and R5 are identical and represent a hydrogen atom, or one of R2 and R5 represents a hydrogen atom or a -CH2 -O-R1 0 radical and the other represents a hydrogen atom, and R1 and R3 are such that: one represents a hydrogen atom and the other is chosen from the radicals -OR6, -CO2 R7 and -CH2 -OR 8, which radicals R1 0, R6 , R7 and R8, identical or different, represent a hydrogen atom or a linear or branched alkyl or alkenyl radical containing at most 5 carbon atoms, R4 represents a free, esterified or salified carboxy radical, said products of formula (I) being in all possible racemic, enantiomeric and diastereomeric isomeric forms, as well as addition salts with mineral acids ux and organic of said products of formula (I), their preparation process and the intermediates of this process. These products exhibit interesting pharmacological properties which justify their use as a medicament. |
