The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one-pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23-90 degrees C) and providing complex polycyclic architectures with high efficiency, and atom and step economy. The bicyclo[2.2.2]octadiene products were obtained with a wide variety of useful functional groups and were successfully applied as chiral ligands for metal catalysis. Computational studies gave a first rationalization of the low activation energy for the cycloaddition based on counter-intuitive favorable dispersive interactions in the transition state.

The existing information supports the use of this material as described in this safety assessment. p-Isopropylbenzyl alcohol was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from the read-across analog benzyl alcohol (CAS # 100-51-6) show that p-isopropylbenzyl alcohol is not expected to be genotoxic. Data from the read-across analog benzyl alcohol (CAS # 100-51-6) provide a calculated MOE > 100 for the repeated dose, developmental, and local respiratory toxicity endpoints. The reproductive toxicity endpoint was evaluated using the ITC for a Cramer Class I material, and the exposure is below the ITC (0.03 mg/kg/day). Data from read-across analog benzyl alcohol (CAS # 100-51-6) provided p-isopropylbenzyl alcohol a NESIL of 5900 mu g/cm(2) for the skin sensitization endpoint. The phototoxicity and photoallergenicity endpoints were evaluated based on UV spectra; p-isopropylbenzyl alcohol is not expected to be phototoxic/photoallergenic. The environmental endpoints were evaluated; p-isopropylbenzyl alcohol was found not to be a PBT as per the IFRA Environmental Standards, and its risk quotients, based on its current volume of use in Europe and North America (i.e., PEC/PNEC) are < 1.

Fingerprint development is one of the most useful techniques in forensic investigation. The powder method is widely used, as it consists of a non-destructive testing. However, some of the powders commonly used are toxic and dangerous to human health. In this sense, monofunctional analogues of curcumin (3a-e) are proposed as novel coloring powders for the development of latent fingerprints. Granulometric and scanning electron microscopy analysis were performed for a better understanding of the interaction between developers and substrates. The best results for the development of fingerprints were obtained with compound (1E,4E)-1,5-di-p-tolylpenta-1,4-dien-3-one (3b). Development with this compound was specific and allowed detection both from male and female donors. Also, in an in vitro experiment, compound 3b presented low cytotoxicity in a mammalian cell line. Based on that, a novel alternative for latent fingerprint developers was proposed.

Three novel heteropolyanion-based Bronsted acidic ionic liquids (BAILs), butane mono sulfoacid-functionalized 1,10-phenanthrolinum, butane mono and bis sulfoacid-functionalized 1,4-dimethylpiperazinium salts of phosphortungstate catalyst (PhBs(1)-PW, [PipBs(1)](3)-PW and [PipBs(2)](3)-(PW)(2)) were synthesized and well characterized with FTIR, H-1 and C-13 NMR, Electro-Spray Ionization Mass Spectrometry (ESI-MS), Elemental analysis (CHNS), EDX and TG analysis techniques. The esterification reactions of monocarboxylic acids with monohydric alcohols were carried out using these catalysts. The introduced catalysts present a self-separation performance after reaction, which can be easily recovered and quite steadily reused as confirmed by six-run recycling test. Moreover, bis sulfoacidfunctionalized 1,4-dimethylpiperazinium salt of phosphortungstate showed the best catalytic performance among the prepared catalysts for the esterification reaction.

Targeting Streptococcus mutans is the primary focus in reducing dental caries, one of the most common maladies in the world. Previously, our groups discovered a potent bactericidal biaryl compound that was inspired by the natural product honokiol. Herein, a structure activity relationship (SAR) study to ascertain structural motifs key to inhibition is outlined. Furthermore, mechanism studies show that bacterial membrane disruption is central to the bacterial growth inhibition. During this process, it was discovered that analog C2 demonstrated a 4-fold better therapeutic index compared to the commercially available antimicrobial cetylpyridinium chloride (CPC) making it a viable alternative for oral care.

In this study, we have designed, synthesized and full characterized a novel biological based acidic nano organocatalyst via condensations reaction of uric acid and phosphorous acid. The obtained compound was named theacrine tetrakis(phosphonic acid) (TTPA) and prepared under refluxing ethanol. This new nano organocatalyst was applied as an efficient and recyclable catalyst for the preparation of novel pyridines with indole moieties via a cooperative vinylogous anomeric based oxidation with good to excellent yields.

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.

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.
