Benzyl alcohol (BnOH) is a natural colorless liquid organic compound that plays an important role in bacteriostatic and anesthetic processes. It is also used to relieve the nerve and ganglionic pain. In this study, we assessed the effect of topical application of BnOH on the Achilles tendon healing process. Sprague Dawley rats were subjected to an experimentally induced wound in the tendon area and then randomized into four groups. Normal saline (0.5 mL) was applied to rats in control group, and BnOH at the concentrations of 0.5 mL 0.075%, 0.15%, 0.3% were applied to the BnOH treatment groups, respectively. Wound treatment with BnOH led to significantly faster functional recovery than with saline. Moreover, treatment of wounds with 0.3% BnOH accelerated the healing process faster than with 0.075% and 0.15% BnOH. Histological analysis of healed wounds that had been treated with BnOH showed more collagen and blood capillaries and fewer inflammatory cells compared to the control. To study the mechanism of the process, the expression of mRNA of TGF-beta 1, Smad2/3 and Smad7 and protein of TGF-beta 1, p-Smad2/3 and Smad7 were quantified by real-time PCR and Western blotting, respectively. Results of this study showed that wounds treated with BnOH significantly enhanced the expression of TGF-beta 1 and Smad2/3 and reduced the expression of Smad7. In general, the current study demonstrated that BnOH improved the recovery process of tendon healing through the promotion of collagen with angiogenesis and showed that TGF-beta plays a role in BnOH treatment of tendon healing.

A method for the synthesis of diverse polysubstituted quinolines from readily available acrylic acids and anthranils has been developed. The weakly coordinating -COOH directing group, which can be tracelessly removed in the cascade cyclization, is essential for this reaction. Diverse polysubstituted quinolines were obtained under mild reaction conditions with simple H2O and CO2 as byproducts. More importantly, 1,2,3,4-tetrahydroacridine, which is the core skeleton of tacrine (an Alzheimer’s disease drug), was conveniently synthesized.

Human dihydroorotate dehydrogenase (DHODH) is a viable target for the development of therapeutics to treat cancer and immunological diseases, such as rheumatoid arthritis (RA), psoriasis and multiple sclerosis (MS). Herein, a series of acrylamide-based novel DHODH inhibitors as potential RA treatment agents were designed and synthesized. 2-Acrylamidobenzoic acid analog 11 was identified as the lead compound for structure-activity relationship (SAR) studies. The replacement of the phenyl group with naphthyl moieties improved inhibitory activity significantly to double-digit nanomolar range. Further structure optimization revealed that an acrylamide with small hydrophobic groups (Me, Cl or Br) at the 2-position was preferred. Moreover, adding a fluoro atom at the 5-position of the benzoic acid enhanced the potency. The optimization efforts led to potent compounds 42 and 53.55 with IC50 values of 41, 44, 32, and 42 nmol/L, respectively. The most potent compound 54 also displayed favorable pharmacokinetic (PK) profiles and encouraging in vivo anti-arthritic effects in a dose-dependent manner.

The push-pull electronic and steric effect of copper porphyrin catalysts on the cross-dehydrogenative coupling (CDC) reaction between the hydroxyl group of phenol substrates and C(sp(3))-H bond have been investigated. Results showed that copper porphyrin bearing electron-withdrawing, bulky steric hindrance or heteroatom of pyridyl groups could increase the catalytic activity in the reaction. 5,10,15,20-(tetrakis(4-pyridyl)porphyrin)copper (CuTPyP) was found the best among all tested catalysts. Phenol substrates bearing various functional groups afforded moderate to excellent yields (99%). Significantly, as compared to other tested copper porphyrins, CuTPyP not only exhibited remarkable higher activity but also could shorten the reaction time from 12 to 6 h.

A thorough study of mild and environmentally friendly electrochemical-induced hydroxylation of aryl halides without a catalyst is presented. The best protocol consists of hydroxylation of different aryl iodides and aryl bromides by water solution in the presence of Et3N under air, affording the target phenols in good isolated yields. Moreover, aryl chlorides were successfully employed as substrates. This methodology also provides a direct pathway for the formation of deoxyphomalone, which displayed a significant anti-proliferation effect.

Photocatalytic oxidation of alcohols with high selectivity is a promising approach for the synthesis of organic compounds under mild conditions and for solar energy conversion. In this work, we report on the highly selective anaerobic photooxidation of alcohols to carbonyl compounds with coupled H-2 production over Pt-loaded Fe-doped SrTiO3 under visible light. Representatively, an optimized apparent quantum efficiency of 13.2 % at 420 nm was obtained for benzyl alcohol oxidation. X-ray absorption fine structure and in situ diffuse reflectance IR spectroscopy revealed that the surface oxygen vacancies and the fine-tuned valence band edge position induced by Fe doping not only contributed to the activation of alpha-C-H bonds in alcohols, but also avoided the over-oxidation of the obtained carbonyl compounds.

It remains challenging to achieve the selective cleavage of C-C bonds in lignin or lignin model compounds to produce aromatic products in high yield and selectivity. We have developed a redox-neutral photocatalytic strategy to accomplish this goal in both beta-O-4 and beta-1 lignin models at room temperature (RT) via proton-coupled electron transfer (PCET) process without any pretreatments of substrate, by adjusting the alkalinity of base to obtain a lignin models/base PCET pair with a bond dissociation free energy close to 102 kcal/mol. Without breaking down C-beta-C-gamma bond and any C-O bonds, this PCET method is 100% atom economy and produces exclusive C-alpha-C-beta bond cleavage products, such as benzaldehydes (up to 97%) and phenyl ethers (up to 96%), in high to excellent yields and selectivities. Preliminary studies indicated that the PCET strategy is also effective for the depolymerization of native lignin at RT, thus providing significantly important foundation to the depolymerization of lignin.

The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5

A new Zr-based MOF, namely, UiO-66-Urea, was prepared through polymerization between the 2-aminoterephthalate linkers of UiO-66-NH2 MOF and 1,4-phenylene diisocyanate under mild reaction conditions. Post-synthetic coating of UiO-66-Urea with choline chloride (ChCl), as easily available, inexpensive, and nontoxic reagent, under thermal and solvent-free conditions resulted in in-situ formation of a deep-eutectic solvent-like on the UiO-66-Urea’s surface, called here ChCI@UiO-66-Urea. The presence of Zr6O4(OH)(4) nodes and urea groups may capable of strong hydrogen bond formation with ChCl. The porous and bioinspired ChCl@UiO-66-Urea was characterized using FT-IR, powder XRD, SEM, EDX elemental mapping, TGA, and BET surface area measurements. Choline chloride-coated UiO-66-Urea was successfully promoted one-pot three-component synthesis of 2-amino-4H-chromenes, as biologically active heterocycles, through reactions of aldehydes, malononitrile, and alpha-naphthol or 4-hydroxycoumarin under solvent-free conditions. The catalytic activity of the respective solid was superior than UiO-66, UiO-66-NH2, UiO-66-Urea, and even ChCl-2Urea due to synergistic effect between actives sites of UiO-66-Urea and ChCl. The reaction includes a consecutive three-step Knoevenagel condensation/Michael addition/cydization mechanism. (C) 2020 Elsevier B.V. All rights reserved.
