Project description:Deep sequencing of mRNA from Chinese tree shrew; Chinese tree shrew (Tupaia belangeri chinensis) is placed in Order Scandentia and embraces many unique features for a good experimental animal model. Currently, there are many attempts to employ tree shrew to establish model for a variety of human disorders such as social stress, myopia, HCV and HBV infection, and hepatocellular carcinoma .We present here a publicly available annotated genome sequence for Chinese tree shrew. Phylogenomic analysis of tree shrew and other mammalians highly supported its close affinity to primates. Characterization of key factors and signaling pathways of the nervous and immune systems in tree shrews showed that this animal had common and unique features, and had essential genetic basis for being a promising model for biomedical researches.

Project description:Six new triterpenoid saponins, aesculusosides A-F (1-6), together with 19 known ones, were isolated from the seeds of Aesculus chinensis. The new structures were elucidated through extensive spectroscopic analyses and by comparison with previously reported data. Some of the isolates were evaluated for their cytotoxic activities against MCF-7 cell line by an MTT assay, and compounds 15, 16, 19, and 23-25 exhibited inhibitory activities against MCF-7 with IC50 values ranging from 7.1 to 31.3 μM.

Project description:The dried seeds of Aesculus chinensis Bge. var. chekiangensis (Hu et Fang) Fang, called "Suo Luo Zi", have been used in traditional Chinese medicine. Nevertheless, most studies have been focused on components of less polarity fractions. In this research, twelve indoles, including six new indole glycosides (1-6) as well as six known analogs were isolated from the polar portion which has been seldom studied. This is the first description of N-glucosylated indoles obtained from the genus of Aesculus. Structures of the new compounds (1-6) were elucidated based on comprehensive interpretation of HRESIMS, 1D and 2D NMR. Additionally, the neuroprotective activities of the N-glucosylated indoles were evaluated for the first time indicating that compounds 1-5 and 9-10 exhibited moderate neuroprotective activities. Further cytotoxicity tests of isolates 1-10 on three human tumor cell lines suggested that none of these compounds were cytotoxic (IC50 > 50 ?M).

Project description:Phytochemical investigation of Aesculus chinensis Bge. var. chekiangensis (Hu et Fang) Fang obtained 33 triterpenoid saponins, including 14 new ones, aesculiside C-P (1-14). The structure elucidations were performed through comprehensive MS, 1D and 2D-NMR analysis, and their absolute configuration was unambiguously determined by X-ray diffraction analysis as well as Mo2(OAc)4-induced ECD method for the first time. All the substances were examined for their cytotoxic activities against three tumor cell lines, Hep G2, HCT-116, and MGC-803. Of these, compounds 8, 9, 14-16, 18, and 22 exhibited potent cytotoxicities against all cell lines with IC50 of 2-21 μM, while compounds 3, 6, 7, 17-19, 20, 24, and 28 depicted moderate activity (IC50 13 to >40 μM). On these bases, the preliminary structure-activity correlations were also discussed. Meanwhile the neuroprotective properties of triterpenoid saponins from Aesculus genus were evaluated for the first time. Among them, compounds 1, 4, 12, 20, 22, 25, 29, and 31 exhibited moderate activities against COCl2-induced PC12 cell injury.

Project description:In this study, we sequenced the complete chloroplast (cp) genome of Aesculus chinensis Bunge var. wilsonii (Rehder) Turland & N. H. Xia and compared it with cp genomes of congeneric species. The cp genome of A. chinensis var. wilsonii is a circular molecule, 156,211 bp in length, with typical quadripartite structure. It has one large single copy (LSC) region of 85,211 bp and one small single copy (SSC) region of 18,124 bp that are separated by two inverted repeat regions (IR) of 26,438 bp. The cp genome encodes 133 genes comprising 85 protein-coding genes, 40 tRNA genes, and eight rRNA ribosomal genes. The overall GC content of the cp genome of A. chinensis var. wilsonii is 37.93%. We conducted amaximum likelihood phylogenetic analysis, which revealed that A. chinensis var. wilsonii is sister to A. wangii and has a close relationship with Acer L. (maples). We expect that the cp genome of A. chinensis var. wilsonii will be useful for DNA barcoding and species delimitation for this species as well as future studies on the conservation, taxonomy, and evolutionary relationships of Aesculus L.
