Abstract
Three new abietane-type diterpenes, named pinusins A-C (1-3) were isolated from Pini Lignum Nodi (the dried tuberculate or branched nodes of Pinus massoniana Lamb.), together with five known diterpenoids (4-8), a flavonoid (9) and a monoterpene (10). The structures of these compounds were elucidated based on detailed spectroscopic analyses (1D, 2D NMR, HRESIMS, IR, and UV), while ECD calculations determined their absolute configurations. All compounds were assayed in vitro for their protective activities against acetaminophen (APAP)-induced hepatotoxicity at 10 μM. Compounds 1-4, 9, and 10 experimentally exerted protective effects against APAP-induced HepG2 cell damage.
期刊介绍:
The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
