Pinellic acid (1), isolated from a medicinal plant Pinelliae tuber, has potent adjuvant activity. The absolute configuration of pinellic acid was expected by derivatization of this compound and CD exciton chirality method. A convergent synthetic route to pinellic acid has been developed via regioselective asymmetric dihydroxylation and stereoselective reduction. The absolute configuration of pinellic acid was determined to be 9S,12S,13S, by comparing with the spectra data of natural and synthetic compounds.

Pinellic acid from the tuber of Pinellia ternate, an active herbal component of the traditional Japanese herbal (Kampo) medicine Sho-seiryu-to, is a C18 trihydroxy fatty acid whose absolute stereochemistry has now been determined. All stereoisomers of pinellic acid were synthesized via regioselective asymmetric dihydroxylation, regioselective inversion, and stereoselective reduction in order to determine their absolute stereochemistries and adjuvant activities. Among this series of isomers, the (9S,12S,13S)-compound, which is a natural product, exhibited the most potent adjuvant activity. Spectral data for all of the stereoisomers of the 1,2-allylic diols were compared and related to their stereochemistries.

, (2008/06/13)
The present invention provides an adjuvant that is a hydroxy unsaturated fatty acid or a derivative thereof, as well as a vaccine preparation containing the adjuvant as a constituent. For example, a vaccine shows sufficient activity to enhance the immunity when a hydroxy unsaturated fatty acid having the following structure is administered:
Trigger lipids inducing pH-dependent liposome fusion

, p. 51 - 68 (2007/10/03)
Aspartic acid-derived artificial lipids (ADLs; s indicates the number of the methylene groups, s=2, 4, 6, 8, 10, 12) (Scheme 1) with various carboxyl alkyl chains as head groups are designed and synthesized, which are incorporated into liposome membranes by sonication. Fluorescence resonance energy transfer (FRET) measurements indicate that ADL6, ADL8 and ADL10 have high lipid-mixing ability in the acidic solution. The other ADLs, however, do not induce remarkable liposome fusion at acidic nor neutral pH. The hydrophobicity of the head groups of ADL6, ADL8 and ADL10 is suitable as triggers of membrane fusion.

Liposomes including aspartic acid-derived artificial lipids (ADL) with various carboxy alkyl chains as head groups (ADLn; n indicates the number of the methylene groups, n = 2,4,6,8,10,12) are prepared, in which ADL6 and ADL8 liposomes induce remarkably high lipid-mixing in the acidic region.
