A novel series of hybrids designed on the basis of aurantiamide acetate and isopropylated genipin were synthesized and biologicallyevaluated as anti‐inflammatoryagents. Among them, compound 7o exhibited the best inhibitory activity against TNF‐α secretion (IC50 = 16.90 μM) and was selected for further in vitro and in vivo functional study. The results demonstrated that 7o was capable of suppressing

A practical synthetic protocol for the preparation of enantioenriched 4‐allyl oxazol‐5‐ones was developed. The key Pd‐catalyzed decarboxylative allylation allowed the attainment of the allylated derivatives in very good yields (83–98 %) and with ee up to 85 %. The corresponding quaternary amino acids can be recovered in their enantiopure form or in high optical purity after a single recrystallization
A series of derivatives of Matijing-Su (MTS, N-(N-benzoyl-l-phenylalanyl)-O-acetyl-l-phenylalanol) was synthesized and evaluated for their anti-hepatitisBvirus (HBV) activities in 2.2.15 cells. The IC50 of compounds 9c (1.40 μM), 9g (2.33 μM) and 9n (2.36 μM), etc. and the selective index of 9n (45.93) of the inhibition on the replication of HBV DNA were higher than those of the positive control

N-substituted .omega.-aminoalkanoyl-.omega.-aminoalkanoic acids and their pharmacologically-acceptable salts (with a base) are useful, e.g., in pharmaceutical-composition form for the treatment or prophylaxis of diseases which are based on inadequate performance of the pancreas, the bile and/or the liver. The compounds are prepared, e.g., by reacting an N-(mono- or di-substituted) .omega.-amino-alkanoic acid with an N-(unsubstituted or monosubstituted) .omega.-aminoalkanoic acid.
