To explore the application potential of dual prodrug strategies in the development of anti-HCV agents, a variety of sofosbuvir derivatives with modifications at the C4 or N3 position of the uracil moiety were designed and synthesized. Some compounds exhibited potent anti-HCV activities, such as 4e and 8a-8c with similar EC50 values (0.20-0.22 mu M) comparative to that of sofosbuvir (EC50= 0.18 mu M) in a genotype 1b based replicon Huh7 cell line. Moreover, 8b displayed a good human plasma stability profile, and was easily metabolized in human liver microsomes expectantly. On the other hand, aiming to discover novel anti-HCV nucleosides, pyrazin-2(1H)-one nucleosides and their phosphoramidate prodrugs were investigated. Several active compounds were discovered, such as 25e (EC50= 7.3 mu M) and S-29b (EC50= 19.5 mu M). This kind of nucleosides were interesting and would open a new avenue for the development of antiviral agents.

The present study evaluated the effects of essential oil (EO) from anise (AO), clove (CO) and thyme (TO) on the performance of lactating Shame goats. Eight lactating Shame goats with average body weight 34.90 +/- 0.9 kg and 3 years old were randomly assigned to four treatments in a duplicated 4 x 4 Latin square design, with four periods of 22 days. In each period, the goats were adapted to the treatments for 15 days and the remaining 7 days was used for sample collection. Goats were fed a basal diet without supplementation (control) or supplemented with anise (AO), thyme (TO) or clove (CO) at a daily dose of 2 mL/head/d. Feed intake was not affected by EO supplementations. Digestibility of organic matter, ether extract and acid detergent fibre was higher (P < 0.05) with EO supplementations when compared with the control. Supplementations of EO had no effect on milk (g/d) yield, protein and lactose, as well as the composition (g/kg) of protein and lactose. Fat yield (g/d) and fat content (g/kg) were greater (P < 0.05) in EO supplemented goats versus those on the control diet. Compared with control, ruminal ammonia-N was not affected whereas, ruminal pH was increased (P = 0.02) with EO supplementations. Rumen total volatile fatty acid concentration and molar proportion of acetate (C2) were higher (P < 0.05) in goats fed CO and TO compared to control, whereas propionate (C3) and butyrate (C4) and C2:C3 proportions were unchanged with EO inclusion. With the exception of a decrease (P = 0.05) in blood urea nitrogen (BUN) with EO supplementations, other blood parameters were not affected. Milk C8 and C12 fatty acids (FA) were lower (P < 0.05) with EO supplementations compared with control. Composition of unsaturated and monounsaturated FA was higher (P < 0.05) and polyunsaturated FA was decreased (P < 0.05) with EO supplementations compared with control. Proportions of C18:1 n-9 C18:3 n-3 and n-3 FA were increased (P < 0.05) and proportions of C18:3 n-6 C20:4 n-6 and n-6 FA were decreased (P < 0.05) in goats fed EO compared to the control group. Overall, all three EOs tested in this study had beneficial effects on digestion, rumen fermentation parameters and milk composition including milk FA profile. Supplementation of CO and TO tended to increase PUFA concentration in the milk which supports their recommendation in the diet of lactating ruminants. Category: indole-building-block.

The selective oxidation of primary alcohols to aldehydes by O-2 instead of stoichiometric oxidants (for example, Mn-VII, Cr-VI, and Os-IV) is an important but challenging process. Most heterogeneous catalytic systems (thermal and photocatalysis) require noble metals or harsh reaction conditions. Here we show that the Bi24O31Br10(OH) photocatalyst is very efficient in the selective oxidation of a series of aliphatic (carbon chain from C-1 to C-10) and aromatic alcohols to their corresponding aldehydes/ketones under visible-light irradiation in air at room temperature, which would be challenging for conventional thermal and light-driven processes. High quantum efficiencies (71% and 55% under 410 and 450nm irradiation) are reached in a representative reaction, the oxidation of isopropanol. We propose that the outstanding performance of the Bi24O31Br10(OH) photocatalyst is associated with basic surface sites and active lattice oxygen that boost the dehydrogenation step in the photo-oxidation of alcohols.

A practically convenient synthesis of (E)-3-arylidene-4diazopyrrolidine-2,5-diones from N-substituted maleimides via the Wittig reaction and the Regitz diazo transfer has been developed. In all 26 cases studied, only one chromatographic purification was required with no need for aqueous workup, which makes this protocol amenable to producing the emerging class of diazo compounds in parallel format.

Herein we report an exclusively ligand-centered redox controlled approach for the dehydrogenation of a variety of N-heterocycles using a Zn(II)-stabilized azo-anion radical complex as the catalyst. A simple, easy-to-prepare, and bench-stable Zn(II)-complex (1b) featuring the tridentate arylazo pincer, 2-((4-chlorophenyl)diazenyl)-1,10-phenanthroline, in the presence of zinc-dust, undergoes reduction to form the azo-anion radical species [1b]which efficiently dehydrogenates various saturated N-heterocycles such as 1,2,3,4-tetrahydro-2-methylquinoline, 1,2,3,4-tetrahydro-isoquinoline, indoline, 2-phenyl-2,3-dihydro-1H-benzoimidazole, 2,3-dihydro-2-phenylquinazolin-4(1H)-one, and 1,2,3,4-tetrahydro-2-phenylquinazolines, among others, under air. The catalyst has further been found to be compatible with the cascade synthesis of these N-heterocycles via dehydrogenative coupling of alcohols with other suitable coupling partners under air. Mechanistic investigation reveals that the dehydrogenation reactions proceed via a one-electron hydrogen atom transfer (HAT) pathway where the zinc-stabilized azo-anion radical ligand abstracts the hydrogen atom from the organic substrate(s), and the whole catalytic cycle proceeds via the exclusive involvement of the ligand-centered redox events where the zinc acts only as the template.

Fenclorim is a commercial herbicide safener with fungicidal activity used for chloroacetanilide herbicides, which might be suitable as a lead compound for screening novel fungicides. However, little has been reported so far on the structure-activity relationship of fungicidal activities of fenclorim or its analogues. Here, a series of 4-chloro-6-substituted phenoxy-2-phenylpyrimidine derivatives was synthesized by a substructure splicing route using fenclorim as a lead compound. The structures of synthesized derivatives were characterized by H-1 NMR, C-13 NMR, and HRMS. Their fungicidal and herbicide safening activities were then evaluated. The results revealed that compound 11 had the best fungicidal activity against Sclerotinia sclerotiorum and Thanatephorus cucumeris, which was better than that of the control pyrimethanil. Moreover, compounds 3, 5, and 25 exhibited excellent safening activities against fresh weight, plant height, and root length, respectively. Such activities were significantly improved when compared to fenclorim. In summary, these findings look promising for the preparation of new fungicides and herbicide safeners based on the structure of fenclorim.

Prostaglandins are among the most important natural isolates owing to their broad range of bioactivities and unique structures. However, current methods for the synthesis of prostaglandins suffer from low yields and lengthy steps. Here, we report a practicability-oriented synthetic strategy for the enantioselective and divergent synthesis of prostaglandins. In this approach, the multiply substituted five-membered rings in prostaglandins were constructed via the key enyne cycloisomerization with excellent selectivity (>20:1 d.r., 98% e.e.). The crucial chiral centre on the scaffold of the prostaglandins was installed using the asymmetric hydrogenation method (up to 98% yield and 98% e.e.). From our versatile common intermediates, a series of prostaglandins and related drugs could be produced in two steps, and fluprostenol could be prepared on a 20-gram scale.

A simple and efficient method for the synthesis of pyrazolopyranopyrimidines under solvent-free has been developed. The one-pot multicomponent condensation of arylaldehydes with hydrazine hydrate, ethyl acetoacetate and barbituric acid in the vicinity of a mesoporous basic nanomagnetic catalyst, namely DBU immobilized on Fe3O4@nSiO(2)@mSiO(2) was synthesized in remarkably high yields and in short reaction times. Significantly, this catalyst can be easily separated from the reaction media by applying an external magnet, and can be reused for several cycles. [GRAPHICS] .

An oxidative trifunctionalization of aryl alkynoates has been devised via the chalcogenide radical triggered intramolecular 1,4-aryl migration/decarboxylation cascade to prepare 1,1-dichalcogenide tetrasubstituted alkenes in high yields (up to 98 %). This operationally simple reaction proceeds under metal-free conditions, can be executed on gram scale, and highlights formal 1,1-difunctionalization of alkynes. Synthetic potential of this protocol was demonstrated through a twofold cascade rearrangement to access highly conjugated tetra-selenylated alkenes along with a cross-dehydrogenative annulation to prepare fluorene derivative.
