Amphipathic aldehydes and their uses as adjuvants and immunoeffectors

A compound, having the formula:

• wherein, R is hydrogen or —C(O)H;
• R1 is a member selected from the group consisting of hydrogen, a substituted C1-20 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, an unsubstituted C1-20 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, a saccharyl group, and a group represented by the formula —C(O)—[C(R3)(R4)]n—COOH,
• wherein each R3 and R4 independently is a member selected from the group consisting of hydrogen and a substituted C1-10 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, and an unsubstituted C1-10 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group;
• and n is a number from 1 to 5;
• R2 is a member selected from the group consisting of hydrogen, a substituted C1-20 saturated unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, an unsubstituted C1-20 saturated unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, and a group represented by the formula —(CH2)mCH(OH)(CH2)pOR5,
• wherein m and p are independently 1 or 2, and R5 is a substituted C2-20 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, or an unsubstituted C2-20 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, or a group represented by the formula
• wherein j is 1-5, and R6 and R7 are independently selected from the group consisting of hydrogen, a substituted C1-20 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group, and an unsubstituted C1-20 saturated, unsaturated or cyclic alkyl, saturated or unsaturated heteroalkyl or saturated or unsaturated heterocycloalkyl group;
• or a pharmacologically acceptable salt thereof.
