Melanogenesis-inhibitory activity and cancer chemopreventive effect of glucosylcucurbic acid from shea (vitellaria paradoxa) kernels

Two jasmonate derivatives, glucosylcucurbic acid (1) and methyl glucosylcucurbate (2), were isolated from the MeOH extract of defatted shea (Vitellaria paradoxa; Sapotaceae) kernels. These and their deglucosylated derivatives, cucurbic acid (3) and methyl cucurbate (4), were evaluated for their melanogenesis-inhibitory and cancer chemopreventive potencies. Compounds 1, 3, and 4 exhibited potent melanogenesis-inhibitory activities in α-melanocyte-stimulating hormone (α-MSH)-stimulated B16 melanoma cells. Western-blot analysis revealed that compounds 1 and 3 reduced the protein levels of MITF (=microphthalmia-associated transcription factor), tyrosinase, TRP-1 (=tyrosine-related protein 1), and TRP-2 mostly in a concentration-dependent manner. In addition, compound 1 exhibited inhibitory effects against Epstein￡Barr virus early antigen (EBV-EA) activation induced with 12-O-tetradecanoylphorbol-13-acetate (TPA) in Raji cells, against TPA-induced inflammation in mice, and against skin tumor promotion in an in vivo two-stage mouse skin carcinogenesis test based on 7,12-dimethylbenz[a]anthracene (DMBA) as initiator, and with TPA as promoter.

An enantiospecific synthesis of (+)-methyl epijasmonate and (-)-methyl cucurbate from L-glutamic acid

An enantiospecific route to jasmonoid natural products, (+) - methyl epijasmonate and (-) -methyl cucurbate from L-glutamic acid is reported. The key step is a 5-(3,4) ene cyclization of a functionalized 1,6-diene as chiron, which sets up three chiral centres with a high degree of diastereoselectivity.

A convenient synthesis of (-)-methyl epijasmonate

A short, enantioselective synthesis of (-)-methyl epi-jasmonate, ent-1, has been achieved starting from readily available Corey lactone aldehyde 9. The key features include the stereoselective installation of 2,3-cis- disubstituted side-chains by hydrogen

Synthesis of 12-Oxophytodienoic Acid (12-OxoPDA) and the Compounds of its Enzymic Degradation Cascade in Plants, OPC-8:0, -6:0, -4:0 and -2:0 (epi-Jasmonic Acid), as their Methyl Esters

The synthesis of 12-Oxophytodienoic acid, and the compounds of its enzymatic degradation sequence, OPC-8:0, -6:0, -4:0 and -2:0, important plant metabolites derived from linolenic acid, is reported.The syntheses use the known cyclopent-3-ene-1,2-diacetic acid as an early intermediate, and this is derived from the Cope rearrangement of 5-vinyltrinorborn-2-ene via bicyclonona-3,7-diene.Iodolactonisation and tributyltin hydride reduction provides the key intermediate (3-oxo-2-oxabicyclooctan-6-yl)acetic acid for the OPC series, whilstphenylselenolactonisation and elimination provides the necessary unsaturated lactone (7-oxo-8-oxabicyclooct-2-en-4-yl)acetic acid for 12-oxoPDA.Members of the OPC-series were made by chain extending the saturated oxabicyclooctane acid: that for the OPC-4:0 involved double Arndt-Eistert reaction, whilst the intermediates for OPC-6:0 and -8:0 were made by Kolbe anodic crossed coupling.The lactones were than converted via their lactols, Wittig reaction, esterfication and oxidation, into the compounds of the OPC ester series, including OPC-2:0 (methyl epi-jasmonate).The unsaturate lactone 8-(7-oxo-8-oxabicyclooct-2-en-4-yl)octanoic acid required for 12-oxoPDA synthesis could also be prepared by anodic synthesis either from (7-oxo-8-oxa-bicyclooct-2-en-4-yl)acetic acid, or from its 2-phenylseleno-2,3-dihydro precursor as elimination occurred concomitantly during the reaction.Since yields were low, the unsaturated acid lactone was converted into its lactol and the (Z)-pent-2-enyl side-chain was inserted first.After TBDMS blocking of the cyclopentene hydroxy group, the side-chain was elaborated to give5-(pent-2-enyl)cyclopent-2-enylacetaldehyde and chain extension carried out by a Grignard-demesylation procedure.Sequential desilylation and depyranylation, followed by oxidation of the diol, gave 12-oxoPDA, isolated as its methyl ester.

Stereoselective Synthesis of Methyl Epijasmonate

Methyl epijasmonate (1) was stereoselectively synthesized from 3-hydroxymethylcyclopentanone (7).The intramolecular alkylation of bromoketone (8) or (9) was the key step to exclusively afford thermodynamically more stable oxahydrindanone (10) or (11).Synthesis was achieved in a 6percent overall yield in 12 steps from (7).

Synthesis of Chiral Methyl Cucurbate and Its Analogs

CUCURBIC ACID AND ITS 6,7-STEREOISOMERS

The derivatives 7-iso-cucurbic acid (7-iso-CA) and 6-epi-7-iso-cucurbic acid (6-epi-7-iso-CA) were prepared from (-)-jasmonic acid (JA) by reduction and cucurbic acid (CA) and 6-epi-cucurbic acid (6-epi--CA) from (+)-7-isojasmonic acid (7-iso-JA).The chromatographic properties (TLC, HPLC, GC) of these derivatives are described and the structures established by physical data. the extracts of different plant materials were analysed with respect to the natural occurence of JA and CA and its 6,7-stereoisomers.JA, 6-epi-CA and 6-epi-7-iso-CA were identified in female flowers of Juglans regia and JA, CA, 6-epi-CA and 6-epi-7-iso-CA in spores of Anemia phyllitidis.JA, CA, 6-epi-CA and 9,10-dihydro-JA were detected in immature caryopses of Secale cereale.In rye JA dominated in young caryopses, while CA level exceeded the amount of JA in the premature fruits.In each tissue 6-epi-CA was found to be a minor component, while CA or 6-epi-7-iso-CA represented the major components; 7-iso-Ca could not be detected.

An Efficient and Stereocontrolled Synthesis of (+/-)-Methyl Epijasmonate and (+/-)-Cucurbic Acid
