Abstract

A new icetexane diterpenoid, 11, 12, 20α-trihydroxyl-7β-methoxyicetexa-8, 11, 13-triene-19, 10-lactone [Phyllane A (1)], and a new abietane diterpenoid, 7β, 20-epoxy-3β, 17-acetoxy-abieta-8, 11, 13-teriene-11, 12-diol [phyllane B (2)], along with two known compounds (3 and 4) were isolated from the methanol (MeOH) extract of twigs and leaves of the folk medicinal Isodon phyllopodus. Their structures were determined by spectroscopic analyses including 2 D NMR spectral data, and further confirmed by X-ray single crystal diffraction. Moreover, the compounds were evaluated for their cytotoxicity and anti-HIV activities, and phyllane A showed anti-HIV activity with an IC50 value of 15.7 μM, but phyllane B was found to be cytotoxic to the A549 host cells with a CC50 value of 108.5 μM.

Abstract

We report the isolation of a novel diterpene, designated as `amethane', from Isodon amethystoides (Lamiaceae). The diterpene [amethinol A; systematic name: (4aR,4bR,7R,10aS)‐4b,7‐dihydroxy‐7‐isopropyl‐1,1‐dimethyl‐9‐oxododecahydrobenzo[a]azulene‐4a(2H)‐carboxylic acid], possesses a unique skeleton containing a six/five/seven‐membered tricyclic system. Intermolecular O—H…O close contacts were found to the carboxyl, carbonyl and hydroxy groups, connecting molecules into a two‐dimensional structure. A possible biosynthetic pathway has been proposed. In addition, the compound was evaluated for its biological activities against different disease targets, and was found to significantly attenuate RORγt‐dependent autoimmune responses.

Abstract

The present study was performed to investigate the chemical components of the branches and leaves of Isodon rubescens. Two 6,7-seco-spiro-lacton-ent-kauranoids were obtained. Based on the extensive spectroscopic analyses, their structures were elucidated as 6-epi-11-O-acetylangustifolin (1) and 11-O-acetylangustifolin (2), respectively. The structure of 2 was further comfirmed by X-ray crystallography analysis. MTT method was employed to evaluate their cytotoxity against human lung cancer cell lines A549 and leukemia cell lines K562. [ABSTRACT FROM AUTHOR]

Abstract

Three new lycodine-type Lycopodiumalkaloids, namely 1-methyllycodine (1), 8α-hydroxy-15,16-dehydro-des-N-methyl-α-obscurine (2), N-methyl-16-hydroxyhuperzine B (3), and one new natural lycodine-type Lycopodiumalkaloid, N-methylhuperzine A (4), along with 11 known analogues (5–15), were isolated from the whole plants of club moss Huperzia serrata. The structures of 1–4were elucidated on the basis of NMR spectroscopic and mass spectrometry data. Among them, compound 1was the first lycodine-type alkaloid possessing a methyl group at C-1. In addition, the structure of 5was confirmed by the single-crystal X-ray crystallography data and its 13C NMR was reported for the first time in current study. Compounds 1–5were tested their BACE1 inhibitory activity.
