Claim:
A sterol-based compound, corresponding to formula (I) in which formula: the carbon in position 4 of the cholesterol skeleton bears moieties T 1 and T 2 , which are, independently, H or CH 3 with CH 3 in the α and/or β position; the carbon in position 24 bears a moiety T 4 which represents H, CH 3 or C 2 H 5 ; the carbon in position 14 bears a moiety T 3 , which is H or a β CH 3 , the bond between carbons 7 and 8 is a single or a double bond; Z represents, in position 5 or 8, either H or OH, H or OH being able to be borne only by a carbon that does not bear a double bond; and R is in position 6 or 7, on a carbon not bearing a double bond, said compound is selected from the group consisting of: a compound corresponding to formula (I) in which the bond between carbons C 7 and C 8 is a double bond, R═NH—(CH 2 ) 3 —NH—(CH 2 ) 4 —NH 2 and T 1 =T 2 =T 3 =H, a compound corresponding to formula (I) in which the bond between carbons C 7 and C 8 is a double bond, T 1 =T 2 =T 3 =H and a compound corresponding to formula (I) in which the bond between carbons C 7 and C 8 is a double bond, T 1 =T 2 =T 3 =H and R=—NH—(CH 2 ) 4 —NH 2 , a compound corresponding to formula (I) in which the bond C 7 -C 8 is a double bond, T 1 =T 2 =T 3 =H and R=—NH—(CH 2 ) 2 —O—(CH 2 ) 2 —O—(CH 2 ) 2 —NH 2 , a compound corresponding to formula (I) in which the bond C 7 -C 8 is a single bond, Z represents OH in position 5 and T 1 =T 2 =T 3 =H, R being in position 6, and R=—NH—(CH 2 ) 3 —NH—(CH 2 ) 4 —NH—(CH 2 ) 3 —NH 2 , a compound corresponding to formula (I) in which the bond C 7 -C 8 is a single bond, Z represents OH in position 5 and T 1 =T 2 =T 3 =H, R being in position 6, and a compound corresponding to formula (I) in which the bond C 7 -C 8 is a single bond, Z represents OH in position 5 and T 1 =T 2 =T 3 =H, R being in position 6 and having the meaning a compound corresponding to formula (I) in which the bond C 7 -C 8 is a single bond, Z represents OH in position 5 and T 1 =T 2 =T 3 =H, R being in position 6 and having the meaning a compound corresponding to formula (I) in which the bond C 7 -C 8 is a single bond, Z represents OH in position 5 and T 1 =T 2 =T 3 =H, R being in position 6 and being: NH—(CH 2 ) 3 —NH—(CH 2 ) 4 —NH 2 .
