Four new metabolites, asperchalasine I (1), dibefurin B (2) and two epicoccine derivatives (3 and 4), together with seven known compounds (5–11) were isolated from a mangrove fungus Mycosphaerella sp. SYSU-DZG01. The structures of compounds 1&n...
Microalgal lipids are a source of valuable nutritional ingredients in biotechnological industries, and are precursors to biodiesel production. Here, the effects of salt-induced stresses, including NaCl, KCl, and LiCl stresses, on the production of li...
A GH49 dextranase gene DexKQ was cloned from marine bacteria Arthrobacter oxydans KQ11. It was recombinantly expressed using an Escherichia coli system. Recombinant DexKQ dextranase of 66 kDa exhibited the highest catalytic activity at pH 9.0 and 55...
New diterpenes, namely, trichodermanins F–H, with a fused 6-5-6-6 ring system were isolated from the fungus Trichoderma harzianum OUPS-111D-4 separated from a marine sponge Halichondria okadai. These chemical structures were elucidated by 1D an...
Two new cembrane-type diterpenoids, lobophytins A (1) and B (3), and four new prostaglandins, (5E)-PGB2 (10), (5E)-13,14-dihydro-PGB2 (11), 13,14-dihydro-PGB2 (12) and 13,14-dihydro-PGB2-Me (13), together with ten known compounds were isolated from t...
Three new phenazine derivatives (1–3), along with known compounds (4–7) of saphenic acid derivatives, were isolated from a deep-sea sediment-derived yeast-like fungus Cystobasidium larynigs collected from the Indian Ocean. The structures...
Three new benzofuranoids, asperfuranoids A–C (1–3), two new phenylpropanoid derivatives (6 and 7), and nine known analogues (4, 5, and 8–14) were isolated from the liquid substrate fermentation cultures of the mangrove endopytic fun...
Herein, we report on the synthesis of a small set of linear precursors of an inosine analogue of cyclic ADP-ribose (cADPR), a second messenger involved in Ca2+ mobilization from ryanodine receptor stores firstly isolated from sea urchin eggs extracts...
Recent advances in sampling and novel techniques in drug synthesis and isolation have promoted the discovery of anticancer agents from marine organisms to combat this major threat to public health worldwide. Bryozoans, which are filter-feeding, aquat...
Despite huge efforts by academia and pharmaceutical industry, cancer remains the second cause of disease-related death in developed countries. Novel sources and principles of anticancer drug discovery are in urgent demand. Marine-derived natural prod...
