Patent ID: 8425879

Claim:
A molecule corresponding to formula (I) below: in which: x represents an integer chosen from: 0 and 1, M represents a metal atom chosen from transition metals, when X represents 0, (M-X) is replaced with two hydrogen atoms, X represents a group chosen from: a halide, and an anion of a carboxylic acid which is pharmaceutically acceptable, R represents a group chosen from: a C 1 -C 15 alkyl chain, optionally interrupted with one or more groups chosen from: an ether (—O—), an amine (—NH—), a thioether (—S—), a ketone (—CO—), an ester (—CO—O—), an amide (—CO—NH—), a urea (—NH—CO—NH—), a thiourea (—NH—CS—NH—), an oxycarbonyl (—O—CO—O—) and a carbamate (—NH—CO—O—), R′ represents a group chosen from: a C 1 -C 6 alkyl, a phenyl and a benzyl, R″ represents a group chosen from: and Z + represents a pharmaceutically acceptable organic or inorganic cation, Y − represents a group which may be chosen from: —COO − and —SO 3 − , A − represents an anion which may be chosen from: a halide, and an anion of a carboxylic acid which is pharmaceutically acceptable, R 1 represents a C 1 to C 10 alkyl.
