CRTh2 (DP2) is a prostaglandin D2 receptor implicated in the recruitment of eosinophils and basophils within the asthmatic lung. Here we report the discovery of a novel series of 3-indolyl sultam antagonists with low nM affinity for CRTh2. These compounds proved to be selective over the other primary prostaglandin D2 receptor (DP1) as well as the thromboxane A2 receptor (TP).

The C(sp2)-H function of indole ketone with diazo compound via a rhodium(II)-catalyzed intramolecular electrophilic trapping reaction under mild conditions in air was demonstrated. The established methodology provided a highly efficient approach for direct synthesis of mutisubstituted tetrahydrocarbazoles with continuous quaternary carbons. The resulting products facilitate further modification to conveniently construct tetrahydrocarbazoles with additional fused heterocyclic rings. By phenotypic screening, several products exhibit good anticancer bioctivities in osteosarcoma cell lines.

A novel series of indolyl and dihydroindolyl glycinamides were identified as potent NPY5 antagonists with in vivo activity from screen hit 1. The dihydroindolyl glycinamide 10a significantly inhibits NPY5 agonist induced feeding at a dose of 0.1 mg/kg. The indolyl glycinamide 12c also inhibits NPY5 agonist induced feeding at a dose of 1 mg/kg. Both compounds 10a and 12c represent potential tools for further investigation into the biology of the NPY5 receptor.

A delta-carboline derived compound, 5-(3?-(9-carbazolyl)-[1,1?-biphenyl]-3-yl)pyrido[3,2-b]indole, was synthesized as a high triplet energy bipolar host material for blue phosphorescent organic light-emitting didoes and it was compared with alpha-carboline derived host material with the same backbone structure. The delta-carboline derived host material showed better electron transport properties than the host with alpha-carboline due to better electron accepting properties. Therefore, the new host material reduced driving voltage and increased the power efficiency of blue phosphorescent organic light-emitting diodes compared to a standard host with alpha-carboline moiety. A high external quantum efficiency of 25.3% and a high power efficiency of 36.4 lm/W were achieved in the blue phosphorescent organic light-emitting diodes.

The valorisation of biomass has been commonly carried out in biorefineries. The environmental concerns about these processes have not been intensely considered, demanding further investigations. Particularly, phenols are founded in high concentrations in biorefinery wastewater and are considered compounds of major concern. In this study, we evaluated the bioconversion of phenols by enzymatic treatment using the enzyme Horseradish peroxidase (HRP) and the Fenton process. The results showed an enzymatic phenol conversion of 97.5% at pH 7.0, enzyme activity of 0.8 U/mL and hydrogen peroxide concentration of 1.61 g/L. So as to enhance the treatment, we evaluate the Fenton reaction as a complementary process for further remaining phenol conversion. The best conditions for Fenton process were achieved using a hydrogen peroxide concentration and [H2O2]:[Fe] ratio of 3.90 g/L and 74, respectively, and the obtained phenol concentration in the treated wastewater was 0.11 mg/L. Chromatography analysis showed that 2-methoxyphenol was the majority compound in the original wastewater, which was subsequently precipitated by the enzymatic treatment. Furthermore, many physicochemical parameters were modified due to the treatment, such as biochemical oxygen demand, chemical oxygen demand and total organic carbon, with removal efficiencies of around 97, 49 and 46%, respectively. HRP combined with Fenton can be considered as an alternative methodology for the biorefinery wastewater treatment, especially regarding the phenols conversion.
