Rafiee, Ezzat published the artcileSynthesis and characterization of carbon@HPW core/shell nanorod using potato as a novel precursor: Efficient catalyst for C-N coupling reaction, Application In Synthesis of 140-28-3, the publication is Arabian Journal of Chemistry (2019), 12(8), 3324-3335, database is CAplus.

Carbon support with nanorod (CSN) structure was synthesized by natural potato as green and very cheap source via hydrothermal method. A novel type of core/shell nanorod catalyst was synthesized by the immobilization of 12-tungstophosphoric acid (HPW) on the surface of the CSN (C@HPW). Characterization of the core/shell nanorod catalyst was carried out using transmission electron microscopy (TEM), X-ray diffraction (XRD) pattern, energy dispersive X-ray (EDX) spectroscopy, Fourier transform IR (FTIR) spectrophotometry, and Raman spectrophotometer. The TEM results showed that morphol. of carbon catalyst support was changed from nanorod to core/sell nanorod by the immobilization of HPW. The characterization data derived from FTIR spectroscopy revealed that HPW on the support exists in the Keggin structure. The C@HPW core/shell nanorod was found to be a unique, effective, and eco-friendly catalyst for the C-N coupling reactions for a broad range of aryl and alkyl amines and alcs. under aerobic conditions at room temperature The excellent conversion at low reaction time showed that the catalyst was strong and sufficient sites, which were responsible for its catalytic performance. The acidity measurements of CSN and C@HPW by means of potentiometric titration with n-butylamine was used to estimate their relative acid strength. Leaching of the HPW from the CSN was minimized by optimization of calcination temperature The reused catalyst for at least five repeating cycles showed excellent activity.

Complexes 1 and 2¡¤5MeOH exhibit gradual thermally induced two-step spin-crossover behavior (SCO) at two Fe^II metal centers, and the transformation of high-spin (HS) to low-spin (LS) Fe^II ions with temperature was confirmed by a combination of x-ray crystallog., variable-temperature Fourier transform IR, variable-temperature magnetic susceptibility, and ⁵⁷Fe Moessbauer spectroscopy. Moreover, complexes 1¡¤MeCN¡¤Et₂O and 1 exhibit a reversible single-crystal-to-single-crystal transformation, and complex 1 undergoes two-step SCO behavior with T_1/2 = 178 and 93 K accompanied by symmetry breaking in the structure.

Yun, Jisu published the artcilePalladium-Catalyzed ¦Á-Arylation of Cyclic ¦Â-Dicarbonyl Compounds for the Synthesis of Ca_V1.3 Inhibitors, Application of N1,N2-Dibenzylethane-1,2-diamine, the publication is ACS Omega (2022), 7(16), 14252-14263, database is CAplus and MEDLINE.

Cyclic ¦Á-aryl ¦Â-dicarbonyl derivatives are important scaffolds in medicinal chem. Palladium-catalyzed coupling reactions of haloarenes were conducted with diverse five- to seven-membered cyclic ¦Â-dicarbonyl derivatives including barbiturate, pyrazolidine-3,5-dione, and 1,4-diazepane-5,7-dione. The coupling reactions of various para- or meta-substituted aryl halides occurred efficiently when Pd(t-Bu₃P)₂, Xphos, and Cs₂CO₃ were used under 1,4-dioxane reflux conditions. Although the couplings of ortho-substituted aryl halides with pyrazolidine-3,5-dione and 1,4-diazepane-5,7-dione were moderate, the coupling with barbiturate was limited. Using the optimized reaction conditions, we synthesized several 5-aryl barbiturates as new scaffolds of Ca_V1.3 Ca²⁺ channel inhibitors. Among the synthesized mols., I was the most potent Ca_V1.3 inhibitor with an IC₅₀ of 1.42¦ÌM.

Shi, Caihua published the artcileActivated release of hexanal and salicylaldehyde from imidazolidine precursors encapsulated in electrospun ethylcellulose-poly(ethylene oxide) fibers, Recommanded Product: N1,N2-Dibenzylethane-1,2-diamine, the publication is SN Applied Sciences (2021), 3(3), 385, database is CAplus.

Hexanal and salicylaldehyde are naturally-occurring antimicrobial volatiles from edible plants known for their efficacy for post-harvest preservation of fruits and vegetables. Due to their volatility and susceptibility to oxidation, these volatiles must be encapsulated within a carrier to control their release, especially when applied in modified atm. and active packaging applications. In this study, salicylaldehyde precursor (SP; 1,3-dibenzylethane-2-hydroxyphenyl imidazolidine) and hexanal precursor (HP) were synthesized through a Schiff base reaction between these aldehydes and N,N’-dibenzylethane-1,2-diamine. The structure of SP was confirmed using NMR and attenuated total reflection-Fourier transform IR (FTIR) spectroscopies. SP and HP, sep. and in combinations, were encapsulated within ethylcellulose-poly(ethylene oxide) (EC-PEO) nonwoven membranes, using a free-surface electrospinning technique. SEM showed that the morphol. of the fibers varied substantially with SP and HP ratio. Specific interactions between SP and HP with the polymers were not detected from the FTIR spectroscopy anal., suggesting that the precursors were mainly phys. entrapped within the EC-PEO fiber matrix. Headspace gas chromatog. showed that the release of hexanal and salicylaldehyde could be activated by contacting the precursor-containing electrospun nonwoven with an acidified agarose gel containing 0.003-0.3 M of citric acid. The delivery system can be promising for controlled release of hexanal and salicylaldehyde to extend the shelf-life of fruits and vegetables.

Hernandez-Coronado, Marcela published the artcileSuccessful second outpatient autologous hematopoietic cell transplant for relapsed POEMS syndrome in a patient with coexisting HIV, HBV and syphilis infections during the COVID-19 pandemic, HPLC of Formula: 140-28-3, the publication is Transplant Immunology (2021), 101412, database is CAplus and MEDLINE.

Polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome is a multisystem autoinflammatory disease due to an underlying plasma cell disorder that lacks a standard treatment strategy because of its rarity. We report a case of relapsed POEMS syndrome successfully treated with a second ambulatory autologous hematopoietic-cell transplantation (AHCT) after a daratumumab desensitization protocol performed during the coronavirus disease (COVID-19) pandemic in a patient with coexisting human immunodeficiency virus (HIV), hepatitis B virus (HBV) and syphilis infections. He is a 37-yr old Latin-American male who had been treated with radiation, CyBorD regimen, AHCT and bortezomib therapy before being referred to our service. It was decided to administer daratumumab therapy and subsequently perform the transplant. Placement of central venous access, fluid infusion, conditioning regimen with melphalan and previously cryopreserved autograft infusion were carried out in an outpatient basis. Following second AHCT, the patient demonstrated clin., VEGF, hematol. response and remains SARS-CoV-2 infection-free and in POEMS remission with excellent quality-of-life at last follow up (6 mo). We evidenced that thanks to an outpatient transplant program, the best therapeutic modalities can be offered to patients with hematol. malignancies in the context of present or future pandemics. Finally, high-complexity patients with HIV infection should have access to the same treatment strategies as non-infected patients. A second AHCT in the outpatient setting is feasible, safe and highly effective to treat patients with relapsed POEMS syndrome.

Despite progress in clin. treatment, cardiovascular diseases are still the leading cause of morbidity and mortality worldwide. Therefore, novel therapeutic approaches are needed, targeting the underlying mol. mechanisms of disease with improved outcomes for patients. Gene therapy is one of the most promising fields for the development of new treatments for the advanced stages of cardiovascular diseases. The establishment of clin. relevant methods of gene transfer remains one of the principal limitations on the effectiveness of gene therapy. Recently, there have been significant advances in direct and transvascular gene delivery methods. The ideal gene transfer method should be explored in clin. relevant large animal models of heart disease to evaluate the roles of specific mol. pathways in disease pathogenesis. Characteristics of the optimal technique for gene delivery include low morbidity, an increased myocardial transcapillary gradient, esxtended vector residence time in the myocytes, and the exclusion of residual vector from the systemic circulation after delivery to minimize collateral expression and immune response. Here we describe myocardial gene transfer techniques with mol. cardiac surgery with recirculating delivery in a large animal model of post ischemic heart failure.

Phenol pollutants such as halophenols and guaiacol derivatives are produced as byproducts of many industrial processes. Aerobic oxidations for their degradation in the context of effluent treatment or environmental remediation often lack selectivity. This work describes a copper (Cu)-catalyzed approach that converts three equivalent of halogenated phenols into a single ortho-quinone, at the expense of reducing dioxygen (O₂) to water (H₂O).
