Damaged cartilage does not readily heal and often requires surgical intervention that only modestly improves outcomes. A synthetic material that could be injected and covalently crosslinked in situ to form a bioactive, mechanically robust scaffold that promotes stem cell chondrogenic differentiation holds promise for next-generation treatment of cartilage lesions. Here, Johnson-Claisen rearrangement chemistry was performed on graphene oxide (GO) to enable functionalization with a primary amine covalently bound to the graphenic backbone through a chemically stable linker. The primary amines are used to form covalent crosslinks with chondroitin sulfate, an important component of cartilage that promotes regeneration, to form a hydrogel (EDAG-CS). The EDAG-CS system gels in situ within 10 min, and the graphenic component imparts improved mechanical properties, including stiffness (320% increase) and toughness (70% increase). EDAG-CS hydrogels are highly porous, resistant to degradation, and enable the growth of human mesenchymal stem cells and their deposition of collagen matrix. This system has potential to improve clinical outcomes of patients with cartilage damage.

Methylthiolation reactions are usually explored to access organosulfur compounds using methanethiol, an extremely flammable and toxic compound. Herein, methylthiomethyl esters were successfully applied as novel methylthiolation reagents in a low cost, transition-metal-free methodology. These reagents allowed the methylthiolation of a wide scope of chalcones, acyl ester derivatives and Morita-Baylis-Hillman acetates with good group tolerance, affording the methylthiolated products in moderate to excellent yields. The reaction mechanism was investigated through several control experiments, as well as by theoretical calculations employing Density Functional Theory. The results strongly support that a sulfurane and a sulfonium ylide appear as key intermediates and that a Pummerer type rearrangement is also crucial for the formation of this novel reagent. Furthermore, the methylthiolation mechanism is likely to proceed through the nucleophilic attack of the reagent, followed by an entropically favoured step involving the acetate attack to the positively charged species, then releasing the product.

The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Herein, we report a radical borylation of aromatic amines through a homolytic C(sp(2))-N bond cleavage. This method capitalizes on a simple and mild activation via a pyrylium reagent ((Sc)Pyry-OTf) thus priming the amino group for reactivity. The combination of terpyridine and a diboron reagent triggers a radical reaction which cleaves the C(sp(2))-N bond and forges a new C(sp(2))-B bond. The unique non-planar structure of the pyridinium intermediate, provides the necessary driving force for the aryl radical formation. The method permits borylation of a wide variety of aromatic amines indistinctively of the electronic environment.

Nano-ferrite-supported Cu nanoparticles (Fe-dopamine-Cu NPs) catalyzed anti-Markovnikov-selective hydroboration of alkenes with B(2)pin(2) is reported under mild reaction conditions. This protocol can be applied to a broad range of substrates with high functional group compatibility. In addition, we demonstrated the use of Fe-dopamine-Cu NPs as a catalyst for the beta-borylation of alpha,beta-unsaturated ketones and ester, providing alkylboronate esters in up to 98% yield. Reuse of the magnetically recyclable catalyst resulted in no significant loss of activity in up to five reaction runs for both systems.

A group of 2-methyl-4-phenylquinoline-chalcone analogs (2a-2x) was synthesized and investigated for anti-depressant, anti-inflammatory, and analgesic effects as cyclooxygenase-2 inhibitors. Pharmacological experiments identified 24 analogs that exhibited anti-depressant, anti-inflammatory, and analgesic activities. In particular, compounds 2c, 2k, and 2w markedly shortened immobility times and exhibited the most anti-depressant activity. In addition, the mechanisms of action of the analogs 2c, 2k, and 2w were likely related to increased serotonin levels in the central nervous system. Compounds 2c, 2k, and 2w displayed reasonable cyclooxygenase-2 inhibitory effects (IC50 values from 0.21 to 0.29 mu mol/L) similar to celecoxib (IC50: 0.19 mu mol/L) in vitro. A molecular docking study of compound 2k also was conducted.

The (Fmes)BH2 center dot SMe2 reagent (7) reacts sequentially with an acetylene and, e.g., xylylisonitrile in a convenient three-component reaction to give a series of unprecedented dihydro-1,3-azaborole derivatives 16. The tolane-derived example 16a was deprotonated and used as a ligand in organometallic chemistry. Compounds 16 served as the starting materials for the straightforward synthesis of various dihydro-1,3-azaborinine derivatives by treatment with an isonitrile. Several diaryldihydro-1,3 azaboroles showed interesting photophysical properties such as aggregation-induced emission and high fluorescence quantum yields.

Polymeric carbon nitride materials have been used in numerous light-to-energy conversion applications ranging from photocatalysis to optoelectronics. For a new application and modelling, we first refined the crystal structure of potassium poly(heptazine imide) (K-PHI)-a benchmark carbon nitride material in photocatalysis-by means of X-ray powder diffraction and transmission electron microscopy. Using the crystal structure of K-PHI, periodic DFT calculations were performed to calculate the density-of-states (DOS) and localize intra band states (IBS). IBS were found to be responsible for the enhanced K-PHI absorption in the near IR region, to serve as electron traps, and to be useful in energy transfer reactions. Once excited with visible light, carbon nitrides, in addition to the direct recombination, can also undergo singlet-triplet intersystem crossing. We utilized the K-PHI centered triplet excited states to trigger a cascade of energy transfer reactions and, in turn, to sensitize, for example, singlet oxygen (O-1(2)) as a starting point to synthesis up to 25 different N-rich heterocycles.
