Derivatives of 1,3-cyclic propandiol phosphate and their action as cell stimulants

A compound of the following formula (I):

• or a pharmaceutically acceptable salt thereof,
• wherein:
• n is 1;
• X is hydrogen, O—R, NH—R, NO2, or N—(C═O)—R;
• X′ is hydrogen or CH2OH;
• Y is O—R1, NH—R1;
• R is hydrogen, linear or branched alkyl, linear or branched acyl, substituted or non-substituted aryl or aralkyl residue;
• R1 is hydrogen, linear or branched alkyl, linear or branched acyl, substituted or non-substituted aryl, alkylcarboxy ester or alkyl-N—R2R3;
• R2 and R3 are independently hydrogen or an alkyl group;
• alkyl is an alkyl group having from 1 to 24 carbon atoms, preferably from 3 carbon atoms to 20 carbon atoms, most preferably from 5 carbon atoms to 15 carbon atoms;
• wherein acyl is an aliphatic saturated or unsaturated C1-C24 acyl group, preferably an acyl group having an even number of carbon atoms, and most preferably an acyl group derived from a natural fatty acid such as a saturated aliphatic acyl group or an unsaturated aliphatic acyl group;
• and
• aryl is a to a mono- or poly-carbocyclic aryl group, most preferably phenyl, optionally substituted by C1-C4-alkyl, halogen and/or hydroxy;
• provided that X and X′ cannot both be hydrogen;
• that when X is NH—R, where R is a linear or branched acyl, then Y is not OR1 where R1 is a 4-nitrophenyl;
• and that when X′ is CH2OH, then X is NH—R or NO2.
