The apical sodium-dependent bile salt transporter (ASBT) plays a pivotal role in maintaining bile acid homeostasis. Inhibition of ASBT would reduce bile acid pool size and lower cholesterol levels. In this report, a series of novel arylsulfonylaminobenzanilides were designed and synthesized as potential inhibitors of ASBT. Most of them demonstrated great(More)
A series of chalcones a1-20 bearing a 4-OMe groups on the A-ring were initially synthesized and their anticancer activities towards HepG2 cells evaluated. Subsequently, a series of chalcones b1-42 bearing methoxy groups at the 2' and 6'-positions of the B-ring were synthesized and their anticancer activities towards five human cancer cell lines (HepG2,(More)
The taxonomic position of an actinobacterium, designated CPCC 204279T, which was isolated from a rhizosphere soil sample of the herb Limonium sinense collected from Xinjiang Province, China, was established using a polyphasic approach. Whole-cell hydrolysates of strain CPCC 204279T contained galactose and arabinose as diagnostic sugars and(More)
Protein kinase B (PknB) is one of the Mycobacterium tuberculosis serine/threonine protein kinases and has an essential role in sustaining mycobacterial growth. Here, we identified and characterized a novel small molecule compound named IMB-YH-8 that inhibited PknB and served as anti-mycobacteria lead compound. IMB-YH-8 inhibited PknB auto-phosphorylation(More)
For screening the potential drugs as anti-liver fibrosis candidates, we established a high- throughput drug screening cell model based on COL1A1 promoter. The activity of COL1A1 promoter and luciferase reporter gene can be elevated by TGF-β1, and inhibited by candidate drugs. We constructed a recombined plasmid with COL1A1 promoter and luciferase reporter(More)
The mol-ecular structure of the title compound, C(10)H(8)Cl(2)O(3), exists in a cis-enol form, which is stabilized by a strong intra-molecular O-H⋯O hydrogen bond. In the crystal, C-H⋯O inter-actions generate zigzag chains along the c axis which are, in turn, linked by further C-H⋯O inter-actions into sheets parallel to (100).
A series of novel 7-(3-alkoxyimino-4-amino-4-methylpiperidin-1-yl)fluoroquinolone derivatives were designed, synthesized and evaluated for their in vitro antibacterial activity and cytotoxicity. All of the target compounds have potent antibacterial activity against the tested Gram-positive and Gram-negative strains, and exhibit good potency in inhibiting(More)
The asymmetric unit of the title compound, C(13)H(20)N(4)O(4), contains two crystallographically independent mol-ecules in which the dihedral angles between the fused pyrrole and pyrazole rings are 5.06 (8) and 1.12 (8)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds into chains parallel to the b axis.
In the title mol-ecule, C13H14N2O2, the dihedral angle between the pyrazole and benzene ring mean planes is 76.06 (11)°, and the conformation of the ethyl side chain is anti [C-O-C-C = -175.4 (3)°]. In the crystal, the only directional inter-actions are very weak C-H ⋯π inter-actions involving both the pyrazole and benzene rings, leading to the formation of(More)
A series of tertiary amine derivatives exhibiting potent HIV-1 protease inhibiting properties were identified. These novel inhibitors were designed based on the structure of Darunavir with modification on the P2 and P2' position. This effort led to discovery of 35e and 38e, which exhibited excellent HIV-1 protease inhibition with IC50 values of 15 nM and 64(More)
