Five new verticillin-type epipolysulfanydioxopiperazines were isolated from wheat solid-substrate fermentation of Gliocladium roseum 1A, and all nine compounds exhibited antinematodal activity against Caenorhabditis elegans and Panagrellus redivivus.
Pegaharmalines A and B, two novel β-carboline alkaloids with unprecedented carbon skeletons from Peganum harmala
Pegaharmalines A (1) and B (2), two novel β-carboline alkaloids with unprecedented carbon skeletons, were isolated from the seeds of Peganum harmala. Their structures were determined by spectroscopic…
Approach to the biosynthesis of atisine-type diterpenoid alkaloids.
The labeled reaction products show that l-serine is the one possible nitrogen source involved in the biosynthesis of atisine-type DAs.
Anti-HIV active daphnane diterpenoids from Trigonostemon thyrsoideum.
A New Lignan and Four New Lignan Glycosides from Mananthes patentiflora
A new lignan, 5-hydroxyjusticidin A (= 9-(1,3-benzodioxol-5-yl)-5-hydroxy-4,6,7-trimethoxynaphtho[2,3-c]furan-1(3H)-one; 1), and four new diphyllin-type lignan glycosides, mananthosides C-F (2-5),…
Anti-tobacco mosaic virus (TMV) Quassinoids from Brucea javanica (L.) Merr.
The antiviral structure-activity relationships of quassinoids against TMV were discussed and eight compounds showed strong antiviral activities, with IC(50) values in the range of 3.42-5.66 microM.
Mixed lignan-neolignans from Tarenna attenuata.
Six new mixed lignan-neolignans and 20 known compounds were isolated from the whole plant of Tarenna attenuata and compounds 1, 2, 5, and 7 scavenged DPPH radical strongly with IC50 values of 72, 87, 45, and 55 microM, respectively.
Benzylphenethylamine alkaloids from Hosta plantaginea with inhibitory activity against tobacco mosaic virus and acetylcholinesterase.
Five new benzylphenethylamine alkaloids were isolated from Hosta plantaginea by bioassay-guided fractionation and established by means of extensive spectroscopic methods, and the relative configuration of 1 was further confirmed by single-crystal X-ray diffraction.
Inhibition of 11β-HSD1 by Tetracyclic Triterpenoids from Euphorbia kansui
The docking results show that the ring part of compounds can insert into the hydrophobic core of h11β-HSD1 and the alkane chain orientates toward the outside.
