The present invention aims to provide an immunostimulating agent superior in an immunostimulatory effect, particularly a compound useful as a vaccine adjuvant, a pharmaceutical composition containing the compound, a vaccine containing the compound and an antigen. The present invention relates to an immunostimulating agent containing at least one kind of a compound represented by the formula (I) : wherein each symbol is as defined in the DESCRIPTION, or a salt thereof, or at least one kind of a compound represented by the formula (II) : wherein each symbol is as defined in the DESCRIPTION, or a salt thereof.
The self-assemblies and gelation of various organicsolvents by salt complexes of two-component N-acylamino acid diastereoisomers are described. The potent organogelator, N-(2-aminoethyl)-α-[-(1-oxoheptadecyl)amino]phenyl) propanamide, was mixed with various N-acyl leucines having different fatty alkyl chain lengths at a ratio of 1:1. In some cases, their complexation resulted in modulations of the
