Carbonyl allylation reactions constitute an important step in the formation of carbon-carbon reactions, and involve various related reactions that chiefly use allylmetal reagents. This report presents a nickel-catalyzed carbonyl allylation reaction using allyl acetate, which produces homoallyl alcohols in moderate to good yields, as an efficient methodology under reductive coupling conditions.

Presented in this paper is photoinduced hydroxylation of organic halides, providing a mild access to a range of functionalized phenols and aliphatic alcohols. These reactions generally proceed under mild reaction conditions with no need for a photocatalyst or a strong base and show a wide substrate scope as well as excellent functional group tolerance. This work highlights the unique role of NaI that allows a challenging transformation to proceed under mild reaction conditions.

Aiming to obtain an efficient anti-proliferative activity, structure- and ligand-based drug design approaches were expanded and utilized to design and refine a small compound library. Subsequently, thirty-two 7,8-disubstituted-1,3-dimethyl-1H-purine-2,6(3H,7H)-dione derivatives were selected for synthesis based on the characteristic pharmacophoric features required for PI3K and B-Raf oncogenes inhibition. All the synthesized compounds were evaluated for their in vitro anticancer activity. Compounds 17 and 22c displayed an acceptable potent activity according to the DTP-NCI and were further evaluated in the NCI five doses assay. To validate our design, compounds with the highest mean growth inhibition percent were screened against the target PI3K alpha and B-Raf(V)(600E) to confirm their multi-kinase activity. The tested compounds showed promising multi-kinase activity. Compounds 17 and 22c anticancer effectiveness and multi-kinase activity against PI3K alpha and B-Raf(V)(600E) were consolidated by the inhibition of B-Raf(WT), EGFR and VEGFR-2 with IC50 in the sub-micromolar range. Further investigations on the most potent compounds 17 and 22c were carried out by studying their safety on normal cell line, in silico profiling and predicted ADME characteristics.

We have prepared, by a sol-immobilization method, bimetallic catalysts with different Au:Pt atomic ratios supported on commercial SrCO3. The catalytic performance for the oxidation reaction of benzyl alcohol of such materials was compared to the monometallic counterparts. aiming at the obtaining of the best composition of the material. It was found that the Au:Pt atomic ratio presents a remarkable effect on the system performance, i.e., Pt-rich systems arc more selective; however, less active. Thus, an equilibrium related to the activity and selectivity of the system was obtained by considering the yield of the system. Also, some density functional theory (DFT) insights were obtained by using a cluster of 14 atoms of Au and 1 or 2 atoms of Pt. X-ray photoelectron spectroscopy, elemental mapping in scanning transmission electron microscopy before and after catalyst usage, flame atomic absorption spectroscopy, Rietveld refinement, among other techniques, were used and associated to the experimental data, which allowed us to propose a catalytic mechanism for the system, which was important since SiCO3 has not been considered before as catalyst support for alcohol oxidation reactions.

Background Baloxavir marboxil (baloxavir) is a new anti-influenza virus agent that is comparable to oseltamivir phosphate (oseltamivir). Since the efficacy of baloxavir in preventing household transmission of influenza is not well established, we compared the secondary household influenza virus transmission rates between patients on baloxavir vs oseltamivir. Methods Between October 2018 and March 2019, we enrolled index patients (diagnosed with influenza and treated with baloxavir or oseltamivir) and household members. The secondary attack rate of household members was compared between index patients treated with baloxavir vs oseltamivir. Risk factors of household transmission were determined using multivariate logistic analyses. Results In total, 169 index patients with influenza type A were enrolled. The median age was 27.0 (interquartile range; 11-57) years. The number of index patients treated with baloxavir and oseltamivir was 49 and 120, respectively. The secondary attack rate was 9.0% (95% confidence interval [CI]: 4.6-15.6) in the baloxavir group and 13.5% (95% CI: 9.8-17.9) in the oseltamivir group. In the multivariate analysis, independent risk factors were 0-6 years of age (odds ratio [OR] 2.78, 95% CI: 1.33-5.82,p < 0.01) and not being on baloxavir treatment. (OR: 0.63, 95% CI: 0.30-1.32,p = 0.22). Conclusion The household secondary attack rate of influenza was comparable in patients treated with baloxavir vs oseltamivir. Therefore, baloxavir can be used as an alternative therapy to oseltamivir in reducing household transmission of influenza. Application In Synthesis of 3-(Trifluoromethyl)phenol.

From a collection containing more than 1500 academic compounds, in silico screening identified a hit for the human A(1) adenosine receptor containing a new purine scaffold. To study the structure activity relationships of this new chemical series for adenosine receptors, a library of 24 purines was synthesized and tested in radioligand binding assays at human A(1), A(2A), A(2B) and A(3) adenosine receptor subtypes. Fourteen molecules showed potent antagonism at A(1), A(3) or dual A(1)/A(3) adenosine receptors. This purine scaffold is an important source for novel biochemical tools and/or therapeutic drugs.

A near-infrared fluorescent probe plays an important role in biosensing and bioimaging because of its high efficiency, sensitivity and negligible background interference in vivo. Azobenzene derivatives demonstrate well-known sensitivity to light and are unique enzyme-responsive candidates in drug delivery and biological detection because the azo double bond can be cleaved by azoreductase. Herein, a novel near-infrared probe of an amphiphilic block copolymer with biological compatibility was synthesized. The azobenzene group attached with the near-infrared fluorescent group AzaBODIPY (boron-dipyrromethenes) linked the hydrophilic (PEG) and hydrophobic (PLA) segments to form the amphiphilic block copolymer PEG-AzaBODIPY-AZO-PLA. PEG(398)-AzaBODIPY-AZO-PLA(144) self-assembled into drug-loaded spherical micelles. The self-assemblies were non-fluorescent owing to the aggregation-induced quenching (ACQ) effect. Triggered by azoreductase, the PEG and PLA segments were disconnected due to the cleavage of the azo bond. This caused the disassembly of the micelles and the subsequent release of the encapsulated drug. Upon disassembly, the emission of the near-infrared fluorescence was activated by the elimination of the ACQ effect. Furthermore, the fluorescence intensity of the self-assemblies in solution increased continuously with drug release. The fluorescence reporting drug release demonstrates the potential applications in biosensing and controlled drug release in the colon of the human intestine.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a secreted protein and its deficiency markedly enhanced the survival rate of patient with cardiovascular diseases (CVDs). Forty berberine (BBR) derivatives were synthesized and evaluated for their activities on down-regulating the transcription of PCSK9 in HepG2 cells, taking BBR as the lead. Structure-activity relationship (SAR) analysis revealed that 2,3-dimethoxy moiety might be beneficial for activity. Among them, 9k displayed the most potent activity with IC50 value of 9.5 +/- 0.5 mu M, better than that of BBR. Also, it significantly decreased PCSK9 protein level at cellular level, as well as in the liver and serum of mice in vivo. Furthermore, 9k markedly increased LDLR expression and LDL-C clearance via downregulating PCSK9 protein. The mechanism of action of 9k is targeting HNF1 alpha and/or Sp1 cluster modulation upstream of PCSK9, a different one from BBR. Therefore, 9k might have the potential to be a novel PCSK9 transcriptional inhibitor for the treatment of atherosclerosis, worthy for further investigation.
