Dendrobium huoshanense polysaccharide prevents ethanol-induced liver injury in mice by metabolomic analysis

The prevalence of alcohol consumption has increased in modern dietary life and alcoholic liver injury can follow. Dendrobium huoshanense polysaccharide (DHP) is a homogeneous polysaccharide isolated from Dendrobium huoshanense, which possesses hepatoprotection function. In this study, we investigated the metabolic profiles of serum and liver tissues extracts from control, ethanol-treated and DHPethanol-treated mice using a UHPLC/LTQ Orbitrap XL MS-based metabolomics approach. Our results indicated that DHP alleviated early steatosis and inflammation in liver histology and the metabolomic analysis of serum and hepatic tissue revealed that first, ethanol treatment mainly altered phosphatidylcholines (PCs) including PC (13:0) and phosphocholine, arachidonic acid metabolites including 20-ethyl PGF2alpha and amino acids including l-Proline; Second, DHP supplementation ameliorated the altered metabolic levels particularly involved in phosphocholine and l-Proline. These data suggested that DHP might restore the perturbed metabolism pathways by ethanol exposure to prevent the progression of alcoholic liver injury.

Lead optimization studies on FimH antagonists: Discovery of potent and orally bioavailable ortho-substituted biphenyl mannosides

Herein, we describe the X-ray structure-based design and optimization of biaryl mannoside FimH inhibitors. Diverse modifications to the biaryl ring to improve druglike physical and pharmacokinetic properties of mannosides were assessed for FimH binding affinity based on their effects on hemagglutination and biofilm formation along with direct FimH binding assays. Substitution on the mannoside phenyl ring ortho to the glycosidic bond results in large potency enhancements several-fold higher than those of corresponding unsubstituted matched pairs and can be rationalized from increased hydrophobic interactions with the FimH hydrophobic ridge (Ile13) or “tyrosine gate” (Tyr137 and Tyr48) also lined by Ile52. The lead mannosides have increased metabolic stability and oral bioavailability as determined from in vitro PAMPA predictive model of cellular permeability and in vivo pharmacokinetic studies in mice, thereby representing advanced preclinical candidates with promising potential as novel therapeutics for the clinical treatment and prevention of recurring urinary tract infections.

2,3-Diamino acid modifying 3S-tetrahydroisoquinoline-3-carboxylic acids: Leading to a class of novel agents with highly unfolded conformation, selective in vitro anti-platelet aggregation and potent in vivo anti-thrombotic activity

In the preparation of anti-thrombotic agents the 2- and 3-positions of 3S-tetra-hydroisoquinoline-3-carboxylic acid (THIQA) were simultaneously modified with amino acids to form 20 novel N-(3S-N-aminoacyl-1,2,3,4-tetrahydroisoquinoline-3-carbonyl)amino acids (8a-t). On an in vitro platelet aggregation model 8a-t selectively inhibit ADP-induced platelet aggregation and their IC50 values are leas than 3.5 nM. On an extracorporeal circulation of arterioveinos cannula model of rats both orally and intraveously effective doses of 8a-t are less than 30 nmol/kg. Cerius2 based stereoview of explores 8a-t having highly unfolded conformation. 3D QSAR analysis gives the importance of the unfolded conformation to high in vitro anti-platelet aggregation and in vivo anti-thrombotic potency rational understanding.

Three-component coupling reactions of isoquinolines, dimethyl acetylenedicarboxylate and indoles: a facile synthesis of 3-indolyl-1,2-dihydro-2-isoquinolinyl-2-butenedioate

A three-component coupling of isoquinolines, dimethyl acetylenedicarboxylate (DMAD) and indoles is achieved for the first time to produce dimethyl (E)-2-[1-(1H-3-indolyl)-1,2-dihydro-2-isoquinolinyl]-2-butenedioates in excellent yields and with high selectivity. The reaction proceeds smoothly at room temperature without a catalyst. Quinoline, DMAD and indole also undergo smooth coupling to furnish dimethyl (E)-2-[2-(1H-3-indolyl)-1,2-dihydro-1-quinolinyl]-2-butenedioate under similar conditions. This method is very useful to functionalize both indoles and aza-aromatic compounds in a one-pot operation.

Diacetyl as a “traceless” visible light photosensitizer in metal-free cross-dehydrogenative coupling reactions

Minisci alkylation is of prime importance for its applicability in functionalizing diverse heteroarenes, which are core structures in many bioactive compounds. In alkyl radical generation processes, precious metal catalysts, high temperatures and excessive oxidants are generally involved, which lead to sustainability and safety concerns. Herein we report a new strategy using diacetyl (2,3-butanedione) as an abundant, visible light-sensitive and “traceless” hydrogen atom abstractor to achieve metal-free cross-dehydrogenative Minisci alkylation under mild conditions. Mechanistic studies supported hydrogen atom transfer (HAT) between an activated C(sp3)-H substrate and diacetyl. Moreover, with the assistance of di-tert-butyl peroxide (DTBP), the scope of the reaction could be extended to strong aliphatic C-H bonds via diacetyl-mediated energy transfer. The robustness of this strategy was demonstrated by functionalizing complex molecules such as quinine, fasudil, nicotine, menthol and alanine derivatives.

HCV NS5A replication complex inhibitors. Part 4.1 optimization for genotype 1a replicon inhibitory activity

A series of symmetrical E-stilbene prolinamides that originated from the library-synthesized lead 3 was studied with respect to HCV genotype 1a (G-1a) and genotype 1b (G-1b) replicon inhibition and selectivity against BVDV and cytotoxicity. SAR emerging from an examination of the prolinamide cap region revealed 11 to be a selective HCV NS5A inhibitor exhibiting submicromolar potency against both G-1a and G-1b replicons. Additional structural refinements resulted in the identification of 30 as a potent, dual G-1a/1b HCV NS5A inhibitor.
