Article Abstract

To study the chemical constituents of "Shan-Ci-Gu" (the tuber of Cremastra appendiculata (D. Don) Makino), the compounds were isolated with silica gel and reverse phase silica gel as well as Sephadex column chromatographic method. Their structures were elucidated on the basis of modern spectra technology. Seven compounds were isolated and identified as 5-methoxybibenzyl-3, 3'-di-O-beta-D-glucopyranoside (1), militarine (2), loroglossin (3), protocatechuic acid (4), succinic acid (5), gastrodin (6), and daucosterol (7). Compound 1 is a new compound. Compounds 2 -6 were isolated from this plant for the first time.

Cold-temperate and Arctic hard bottom coastal ecosystems are dominated by kelp forests, which have a high biomass production and provide important ecosystem services, but are subject to change due to ocean warming. However, the photophysiological response to increasing temperature of ecologically relevant species, such as Laminaria digitata, might depend on the local thermal environment where the population has developed. Therefore, the effects of temperature on growth rate, biochemical composition, maximum quantum yield, photosynthetic quotient and carbon budget of young cultured sporophytes of Laminaria digitata from the Arctic at Spitsbergen (SPT; cultured at 4, 10 and 16 °C) and from the cold-temperate North Sea island of Helgoland (HLG; cultured at 10, 16 and 22 °C) were comparatively analyzed.

In the search for novel natural products with hepatoprotective effects against acetaminophen-induced acute liver injury, the marine-derived fungus WHUF0198 was investigated. Seventeen undescribed pyranopyridone alkaloids, aculeapyridones A-Q (-), were isolated by bioactivity-guided fractionation of an extract obtained by coculture of the WHUF0198 with the mangrove-associated fungus sp. DM27.

Quinoline is a highly privileged scaffold with significant pharmacological potential. Introducing a carbonyl group into the quinoline ring generates a quinolone ring, which exhibits promising biological properties. Incorporating a carboxamide linkage at different positions within the quinoline and quinolone frameworks has proven an effective strategy for enhancing pharmacological properties, particularly anticancer potency.
