2Chartrenoline, a novel alkaloid isolated from a marine Streptomyces chartreusis NA02069显示文摘A novel alkaloid, chartrenoline(1), featuring an unusual 6/6/5/5-tetracyclic nucleus, was isolated from a marine Streptomyces chartreusis NA02069. The structure of 1 including its absolute configurations was established by extensive analyses of its high resolution mass, NMR and single-crystal X-ray diffraction data. A plausible biosynthetic pathway for chartrenoline(1) is proposed.Chengli Liu Chenglong Yang Yingjie Zeng Jing Shi Lingyu Li Wei Li Ruihua Jiao Renxiang Tan Huiming Ge 2019Chinese Chemical Letters2019,30,1:3
3An acidic polysaccharide with xylose branches from Porphyra yezoensis显示文摘An acidic polysaccharide (PY3) was isolated from the hot water extract of the red algae Porphyra yezoensis by successive column chromatographies over DEAE-cellulose and Sephadex G-200. PY3 with an average molecular weight of 1.8×105 was demonstrated to be composed of galactose (Gal), 3,6-anhydrogalactose (3,6-AnGal), 6-OSO3-galactose (6-OSO3-Gal) and xylose (Xyl) in an approximate molar ratio of 25:15:10:1. In view of Smith degradation and me-thylation and on the basis of spectral evidence including those of IR, GC, GC-MS, and 1H and 13C NMR, the most probable repeating unit of PY3 could be proposed as [(1-3)β-D-Gal(1- 4)α-L-3,6-AnGal]3-[1-3)β-D-Gal(1-4)α-L-6-OSO3-Gal]2 with a xylose moiety at the C6 of one of every twenty-five β-D-Gal residues. To our knowledge, PY3 was shown to be the first porphyran possessing occasional xylose branches.ZHANG Weiyun CHEN Hao WANG Shuijuan XIA Zhonghao FEI Xiugeng TAN Renxiang 2001Chinese Science Bulletin2001,46,3:3
4Symbionts, a promising source of bioactive natural products显示文摘Symbionts are microorganisms residing in multicellular hosts(e.g., plants and animals), and they have been witnessed to be a rich source of diverse functional molecules. This review describes structures and biological activities of symbiont-derived secondary metabolites commonly referred to as 'natural products', and highlights that symbiotic microbes represent an underexplored reservoir of natural products with unique scaffolds and promising significance in managing human healthcare and agricultural production.Xuan Zhang Wei Wei Renxiang Tan 2015Science China Chemistry2015,58,7:2

15Cytotoxic and antibacterial polyketide-indole hybrids synthesized from indole-3-carbinol by Daldinia eschscholzii显示文摘Two skeletally undescribed polyketide-indole hybrids(PIHs), named indolchromins A and B,were generated from indole-3-carbinol(I3 C) in the fungal culture(Daldinia eschscholzii). The indolchromin structures were elucidated mainly by their 1 D and 2 D NMR spectra with the former confirmed by the single-crystal X-ray crystallographic analysis. Each indolchromin alkaloid was chirally separated into four isomers, whose absolute configurations were assigned by comparing the recorded circular dichroism(CD) spectra with the electronic CD(ECD) curves computed for all optional stereoisomers. Furthermore, the indolchromin construction pathways in fungal culture were clarified through enzyme inhibition, precursor feeding experiment, and energy calculation. The cascade reactions,including decarboxylative Claisen condensation catalyzed by 8-amino-7-oxononanoate synthase(AONS),C(sp3)-H activation, double bond migration, and Michael addition, all undergone compatibly during the fungal cultivation. In an MIC range of 1.3–8.6 μmol/L,(2 S,4 R)-and(2 R,4 S)-indolchromin A and(2 R,4 S)-indolchromin B are inhibitory against Clostridium perfringens, Clostridium difficile, Veillonella sp.,Bacteroides fragilis, and Streptococcus pyogenes.(2 R,4 S)-Indolchromin A and(2 S,4 S)-indolchromin B were cytotoxic against the human breast cancer cell line MDA-MB-231 with IC50 values of 27.9 and131.2 nmol/L, respectively, with the former additionally active against another human breast cancer cell line MCF-7(IC_(50)94.4 nmol/L).Liping Lin Nan Jiang Huimin Wu Yaning Mei Jie Yang Renxiang Tan 2019Acta Pharmaceutica Sinica B2019,9,2:1
