octane/potato

The stereochemically restricted bicyclic analogue of 7-epi-jasmonic acid was synthesized from a known bicyclo[3.3.0]octane derivative. The enol triflate derived from the bicyclic compound was subjected to palladium-catalyzed coupling with allyltributyltin to give the desired carbon skeleton.

The linoleyl alcohol oxidation catalyzed by potato tuber 5-lipoxygenase was found to be efficiently inhibited by stable nitroxyl radicals: 1-oxyl-2,2,6,6-tetramethylpiperidin-4-yl 1-bicyclo[2,2,2]octane-1-carboxylate, 1-adamantylacetate, dodecanoate, and octadecanoate. The dependence of apparent

Seven polyketides, including four new ones named as varilactones A-B (1-2) and wortmannilactones M-N (3-4), as well as three biogenetically related known wortmannilactones E, F and H (5-7), were isolated from the fungus Penicillium variabile HXQ-H-1, cultivated in potato-based medium with the

Penicitroamide (1), a new metabolite with a new framework, was isolated from the ethyl acetate extract of the PDB (Potato Dextrose Broth) medium of Penicillium sp. (NO. 24). The endophytic fungus Penicillium sp. (NO. 24) was obtained from the healthy leaves of Tapiscia sinensis Oliv. The structure

Two rapid assays for the soluble epoxide hydrolase (sEH) are described. First, a sensitive radiometric assay based on thin-layer chromatography of [(14)C]-cis-9,10-epoxystearic acid and its corresponding diol ((14)C]-9,10-dihydroxystearic acid) is described. The cis fatty acid oxide exhibits higher

A synthesis of the bicyclo[2.1.1]hexane substructure of solanoeclepin A (1), the most active natural hatching agent of potato cyst nematodes, was approached via an intramolecular [2 + 2] photocycloaddition. Aldehyde 12 containing the dioxenone chromophore served as a useful starting material,
