Objective: (+)-Clausenamide ((+)-CLA), the active ingredient of wampee, was isolated from the leaves of Clausena lansium (Lour.) Skeels. This study aimed to evaluate the protective potential of ...
Aim The present study developed a CYP3A4-expressed Caco-2 monolayer model at which effects of the efflux-metabolism alliance on the transport and uptake of clausenamide(CLA) enantiomers as CYP3A4 substrates were inv...
Clausenamide(clau)is one of seven novel compounds isolated from Clausena lansium(Lour)skeels.Clau is unusual in that it contains 4 chiral centers yielding 8 pairs of enantiomers.After identification of the configurati...
A six-step synthesis of (-)-clausenamide is described. Optically pure (R,E)-1,3-diphenylallylic alcohol was ac-etylated and then subjected to an Ireland-Claisen rearrangement, giving the γ,δ-unsaturated acid, wh...

(-)-Clausenamide is a drug candidate under Phase I clinical trial for treatment of Alzheimer's disease (AD). In order to elucidate the substituent related structure-activity relationship, six one-substituent modi...
A method of high performance liquid chromatographic separation of clausenamide enantiomers with chiral-AGP(α_1-acid glycoprotein) stationary phases has been established.The absolute configurations of(-)clausenami...
BACKGROUND: Aggregation of β-amyloid peptide (A β ), excitatory intoxication, oxidation injury and inflammation reaction are generally regarded as the main pathogenesis for Alzheimer disease (AD). ( - ) claus...
Aim: To study the effects of nine synthetic clausenamide with different stereo structures on liver glutathione (GSH) biosynthesis and glutathione S-transferase (GST) activity in mice. Methods: The nine test comp...
Intramolecular cyclization of β -methyl substituted epoxide under aprotics (e.g. LDA in benzene) and protic conditions (e.g. LiOH in MeOH/H2O)both gave a mixture of β-,γ-, δ- and ε-lactam but in different ratio.
