Author is Mezei, Gellert; Kampf, Jeff W.; Pan, Shilie; Poeppelmeier, Kenneth R.; Watkins, Byron; Pecoraro, Vincent L..

Upon crystallization in high yields, metallacrowns form compartments that are capable of asym. encapsulating three isonicotinate guests. Isonicotinate⊂{Ln[Cu(L-pheHA)]5}2(isonicotinate)(NO3)2(H2O)19 (I) was prepared from reaction of Ln(NO3)3[Cu(L-pheHA)]5 (pheHA = phenylalanine hydroxamic acid) and isonicotinic acid. I was characterized by single crystal x-ray diffraction anal. and the possibility of incorporating similar guest mols. into I was explored, but none of the guests formed similar structures under the same exptl. conditions. In I the three isonicotinate mols. stretch across the two metallacrown planes within the compartment, with the pyridine N atom from one metallacrown and the carboxylate group bridging copper and gadolinium atoms on the other metallacrown.

Compound: 3-Pyridinepropionic acid, is researched, Molecular C8H9NO2, CAS is 3724-19-4, about Photochemical Organocatalytic Benzylation of Allylic C-H Bonds.

Authors report a radical-based organocatalytic method for the direct benzylation of allylic C-H bonds. The process uses nonfunctionalized allylic substrates and readily available benzyl radical precursors and is driven by visible light. Crucial was the identification of a dithiophosphoric acid that performs two distinct catalytic roles, sequentially acting as a catalytic donor for the formation of photoactive electron donor-acceptor (EDA) complexes and then as a hydrogen atom abstractor. By mastering these orthogonal radical generation paths, the organic catalyst enables the formation of benzylic and allylic radicals, resp., to then govern their selective coupling. The protocol was also used to design a three-component radical process, which increased the synthetic potential of the chem.

The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate.

P.; Silversmith, A. J.; Brewer, K. S.; Boye, D. M..

Chelation of rare-earth (RE) ions is investigated as a means of enhancing the optical properties of RE-doped silica sol-gels. Two chelating agents [2,6-pyridine-dicarboxylic acid (PDC) and 3-pyridinepropionic acid (PPA)] and two different synthesis techniques are studied. Eu(PDC) gels exhibit intense 5D0 → 7F2 fluorescence in the red under UV excitation and long fluorescence lifetimes compared to Eu(PPA) gels and to gels without a chelating agent. This behavior indicates that the PDC mol. remains associated with the Eu after incorporation into the gel. Similar behavior is seen for 5D4 → 7F5 green fluorescence in Tb(PDC).

Author is Wu, Nannan; Lian, Guangyu; Sheng, Jingyi; Wu, Dan; Yu, Xiyong; Lan, Huiyao; Hu, Wenhui; Yang, Zhongjin.

Targeting the SMAD3 protein is an attractive therapeutic strategy for treating cancer, as it avoids the potential toxicities due to targeting the TGF-β signaling pathway upstream. Compound SIS3 was the first selective SMAD3 inhibitor developed that had acceptable activity, but its poor water solubility limited its development. Here, a series of SIS3 analogs was created to investigate the structure-activity relationship for inhibiting the activation of SMAD3. On the basis of this SAR, further optimization generated a water-soluble compound, 16d, which was capable of effectively blocking SMAD3 activation in vitro and had similar NK cell-mediated anticancer effects in vivo to its parent SIS3. This study not only provided a preferable lead compound, 16d, for further drug discovery or a potential tool to study SMAD3 biol., but also proved the effectiveness of our strategy for water-solubility driven optimization.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of novel sensitizers with a linear conjugated di(1-benzothieno)[3,2-b:2′,3′-d]pyrrole unit for dye-sensitized solar cells, published in 2019-03-31, which mentions a compound: 1116-98-9, mainly applied to dye sensitized solar cell, Quality Control of tert-Butyl 2-cyanoacetate.

Three novel D-π-A structural metal-free organic sensitizers (DBTP-1∼3) are designed, in which a linear planar aromatic group, the di(1-benzothieno)[3,2-b:2′,3′-d]pyrrole is first introduced as the π-bridge for dye-sensitized solar cells. Triphenylamine, 9,9-dimethyle-9H-fluorene and carbazole serve as the electron donor, resp., while cyanoacrylic acid is used as an electron acceptor and anchoring unit. The photophys., electrochem., theor. calculations have been employed to apprehend the correlation between the structures of DBTP-1∼3 and their photovoltaic performances. Further, co-adsorption studies are used to investigate the electronic recombination of the target dyes. As a result, the maximum power conversion efficiency of 6.50% (short-circuit current of 14.66 mA cm-2, open-circuit voltage of 0.67 V, and fill factor of 66%) for the 2 mM chenodeoxycholic acid co-adsorbed device based on DBTP-1 is obtained, while without any co-adsorbent it gives efficiency of 4.55%. The standard dye N719 gives 8.54% power conversion efficiency.

After consulting a lot of data, we found that this compound(1116-98-9)Quality Control of tert-Butyl 2-cyanoacetate can be used in many types of reactions. And in most cases, this compound has more advantages.

The typically low aqueous solubilities of small, hydrophobic organic ampholytic mols. limit the production rates that can be achieved in their isoelec. trapping (IET) separations and call for the use of hydro-organic mixtures as solvents. The compatibility of methanol-water mixtures and poly(ethylene terephthalate) substrate-supported isoelec. polyacrylamide hydrogels, developed for binary IET separations in a Gradiflow BF200IET unit, was studied. The isoelec. polyacrylamide-based hydrogels retained their functional and mech. integrities when the methanol concentration in the hydro-organic solvent mixture was kept at or <25% (volume/volume). The utility of the hydro-organic media was demonstrated in the purification of a hydrophobic ampholytic compound, tech. grade 4-hydroxy-3-(morpholinomethyl) benzoic acid. Production rates ≤7 mg/h were achieved using small, 15 cm2 active surface area isoelec. membranes.

β-(3-Pyridyl)propionic acid (I) and trans-β-(3-pyridyl)acrylic acid (II) retarded the growth of roots and hypocotyls and decreased the in vivo and in vitro enzymic activity of succinate dehydrogenase (III) in S. alba, but had little effect on cytochrome oxidase activity. II was approx. 2-fold more potent than I in reducing III, apparently because of the styrylpyridine moiety in II.
