The disclosure refers to cationic lipothiophosphoramidates for in vitro and in vivo gene delivery, to the use thereof for gene delivery, as well as to liposomes and lipoplexes comprising such cationic lipothiophosphoramidates and to a method for preparing such cationic lipothiophosphoramidates.
The present invention has for an object a cationic lipophilic compound of the following general formula (I):
wherein:
a) R
1
and R′
1
each represent, independently from one another, an alkyl chain, an alkenyl chain or a polyalkenyl chain with from 10 to 24 carbon atoms, with the polyalkenyl chain having from 2 to 4 double links;
b) R
2
is a hydrogen atom or an alkyl chain having from 1 to 4 carbon atoms; and
R
3
is a group with the following formula (IIa) —(CH
2
)
n
— or following formula (IIb) —C(═NH)—NH—(CH
2
)
n
— wherein: n is an integer equal to 0, 1, 2, 3 or 4; and
d) A
+
is an organic cation;
e) X
−
is an anion.
A traction drive fluid comprising a naphthenic compound represented by the formula
1
wherein R
1
is an alkyl group, which may have a naphthene ring, having 1 to 8 carbon atoms, R
2
through R
4
are each independently hydrogen or an alkyl group, which may have a naphthene ring, having 1 to 8 carbon atoms, and A is a naphthenic hydrocarbon group, a saturated polycyclic hydrocarbon group, a naphthenic ester group, and a naphthenic carbonate group.

A lubricating oil used in a friction-type drive power transmission apparatus which includes: at least one of two additives; a first additive selected from at least one of an aliphatic amine having a saturated or unsaturated hydrocarbon group with a carbon number of 12 to 20 (Chemical Formula 1) and an aliphatic amine ethylene oxide adduct having a saturated or unsaturated hydrocarbon group with a carbon number of 12 to 20 (Chemical Formula 2).
The present invention relates to fluorescent and/or targeting lipophilic compounds having the general formula (R1O)(R2O)P(O)—R3-R4-R5 wherein R1 and R2 are each independently a linear or branched, saturated or unsaturated C2-C24 alkyl, or a linear or branched, saturated or unsaturated C2-C24 monoalkenyl or polyalkenyl, the polyalkenyl having from 2 to 4 double bonds, or a linear or branched, saturated or unsaturated C2-C24 monoalkinyl or polyalkinyl, the polyalkinyl having from 2 to 4 triple bonds; R3 is selected from 0, S, —C(R6)2-, —CH(R7)-, —C(S)—N(R6)-, —CH(SR7)-S—S— or —N(R6)- wherein R6 is a hydrogen atom or a C1-C4 alkyl, and R7 is a C1-C4 alkyl; R4 comprises at least one junction function and at least one linker; and R5 is at least one chemical fluorescent group or at least one targeting group. Methods for preparing said lipophilic compounds are also disclosed.
