Moreno-Sanz, Guillermo published the artcileSynthesis and Structure-Activity Relationship Studies of O-Biphenyl-3-yl Carbamates as Peripherally Restricted Fatty Acid Amide Hydrolase Inhibitors, COA of Formula: C14H20BNO3, the publication is Journal of Medicinal Chemistry (2013), 56(14), 5917-5930, database is CAplus and MEDLINE.

The peripherally restricted fatty acid amide hydrolase (FAAH) inhibitor URB937 (I, cyclohexylcarbamic acid 3′-carbamoyl-6-hydroxybiphenyl-3-yl ester) is extruded from the brain and spinal cord by the Abcg2 efflux transporter. Despite its inability to enter the central nervous system (CNS), I exerts profound antinociceptive effects in mice and rats, which result from the inhibition of FAAH in peripheral tissues and the consequent enhancement of anandamide signaling at CB₁ cannabinoid receptors localized on sensory nerve endings. In the present study, we examined the structure-activity relationships (SAR) for the biphenyl region of compound I, focusing on the carbamoyl and hydroxyl groups in the distal and proximal Ph rings. Our SAR studies generated a new series of peripherally restricted FAAH inhibitors and identified compound II (cyclohexylcarbamic acid 3′-carbamoyl-5-hydroxybiphenyl-3-yl ester) as the most potent brain-impermeant FAAH inhibitor disclosed to date.

Zhou, Wanyi published the artcileGlucose and MMP-9 dual-responsive hydrogel with temperature sensitive self-adaptive shape and controlled drug release accelerates diabetic wound healing, Safety of 4-(5-(p-Tolyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl)benzenesulfonamide, the publication is Bioactive Materials (2022), 1-17, database is CAplus and MEDLINE.

Chronic diabetic wounds are an important healthcare challenge. High concentration glucose, high level of matrix metalloproteinase-9 (MMP-9), and long-term inflammation constitute the special wound environment of diabetic wounds. Tissue necrosis aggravates the formation of irregular wounds. All the above factors hinder the healing of chronic diabetic wounds. To solve these issues, a glucose and MMP-9 dual-response temperature-sensitive shape self-adaptive hydrogel (CBP/GMs@Cel&INS) was designed and constructed with polyvinyl alc. (PVA) and chitosan grafted with phenylboric acid (CS-BA) by encapsulating insulin (INS) and gelatin microspheres containing celecoxib (GMs@Cel). Temperature-sensitive self-adaptive CBP/GMs@Cel&INS provides a new way to balance the fluid-like mobility (self-adapt to deep wounds quickly, approx. 37°C) and solid-like elasticity (protect wounds against external forces, approx. 25°C) of self-adaptive hydrogels, while simultaneously releasing insulin and celecoxib on-demand in the environment of high-level glucose and MMP-9. Moreover, CBP/GMs@Cel&INS exhibits remodeling and self-healing properties, enhanced adhesion strength (39.65 ± 6.58 kPa), down-regulates MMP-9, and promotes cell proliferation, migration, and glucose consumption. In diabetic full-thickness skin defect models, CBP/GMs@Cel&INS significantly alleviates inflammation and regulates the local high-level glucose and MMP-9 in the wounds, and promotes wound healing effectively through the synergistic effect of temperature-sensitive shape-adaptive character and the dual-responsive system.

Zhao, Yanbin published the artcileVanadium-catalyzed Oxidative Conversion of Primary Aromatic Alcohols into Amides and Nitriles with Molecular Oxygen, SDS of cas: 1453-82-3, the publication is Chemistry – An Asian Journal (2022), 17(11), e202200224, database is CAplus and MEDLINE.

Herein, a vanadium-based material V-N-C-700 was prepared via a simple and convenient method, and employed for liquid-phase catalytic ammoxidation of alcs. RCH₂OH (R = n-Bu, Ph, pyridin-2-yl, etc.) with mol. oxygen. By using V-N-C-700/2-picolinic acid, primary aromatic alcs. were smoothly converted into the amides RC(O)NH₂ and nitriles RCN in the presence of urea. The corresponding aldehydes RCHO are the key intermediates, and 2-picolinic acid could significantly enhance oxidation of alcs. into aldehydes. The amides were formed simultaneously along with nitriles, rather than only from nitriles via successive hydration. This work further expands non-noble metal catalysts for the preparation of amides and nitriles.

Zhang, Jing published the artcileEffect of Sacubitril/Valsartan on the Right Ventricular Function and Pulmonary Hypertension in Patients With Heart Failure With Reduced Ejection Fraction: A Systematic Review and Meta-Analysis of Observational Studies., Product Details of C24H29N5O3, the publication is Journal of the American Heart Association (2022), 11(9), e024449, database is MEDLINE.

Background Sacubitril/valsartan (S/V) demonstrated significant effects in improving left ventricular performance and remodeling in patients with heart failure with reduced ejection fraction. However, its effects on the right ventricle remain unclear. This systematic review and meta-analysis aimed to assess the impact of S/V on right ventricular function and pulmonary hypertension. Methods and Results We searched PubMed, Embase, Cochrane Library, and Web of Science from January 2010 to April 2021 for studies reporting right ventricular and pulmonary pressure indexes following S/V treatment. The quality of included studies was assessed using the Newcastle-Ottawa scale. Variables were pooled using a random-effects model to estimate weighted mean differences with 95% CIs. We identified 10 eligible studies comprising 875 patients with heart failure with reduced ejection fraction (mean age, 62.2 years; 74.0% men), all of which were observational. Significant improvements on right ventricular function and pulmonary hypertension after S/V initiation were observed, including tricuspid annular plane systolic excursion (weighted mean difference, 1.26 mm; 95% CI, 0.33-2.18 mm; P=0.008), tricuspid annular peak systolic velocity (weighted mean difference, 0.85 cm/s; 95% CI, 0.25-1.45 cm/s; P=0.005), and systolic pulmonary arterial pressure (weighted mean difference, 7.21 mm Hg; 95% CI, 5.38-9.03 mm Hg; P<0.001). Besides, S/V had a significant beneficial impact on left heart function, which was consistent with previous studies. The quadratic regression model revealed a certain correlation between tricuspid annular plane systolic excursion and left ventricular ejection fraction after excluding the inappropriate data (P=0.026). Conclusions This meta-analysis verified that S/V could improve right ventricular performance and pulmonary hypertension in heart failure with reduced ejection fraction, which did not seem to be fully dependent on the reverse remodeling of left ventricle.

Giliomee, Johnel published the artcileEvaluation of composition effects on the physicochemical and biological properties of polypeptide-based hydrogels for potential application in wound healing, Recommanded Product: H-Lys(Boc)-OH, the publication is Polymers (Basel, Switzerland) (2021), 13(11), 1828, database is CAplus and MEDLINE.

In this study, the effect of crosslinking and concentration on the properties of a new library of low-concentration poly(Lys₆₀-ran-Ala₄₀)-based hydrogels for potential application in wound healing was investigated in order to correlate the hydrogel composition with the desired physicochem. and biofunctional properties to expand the assortment of poly-L-lysine (PLL)-based hydrogels suitable for wound healing. Controlled ring-opening polymerization (ROP) and precise hydrogel compositions were used to customize the physicochem. and biofunctional properties of a library of new hydrogels comprising poly(L-lysine-ran-L-alanine) and four-arm poly(ethylene glycol) (P(KA)/4-PEG). The chem. composition and degree of crosslinking via free amine quantification were analyzed for the P(KA)/4-PEG hydrogels. In addition, the rheol. properties, pore morphol., swelling behavior and degradation time were characterized. Subsequently, in vitro cell studies for evaluation of the cytotoxicity and cell adhesion were performed. The 4 wt% 1:1 functional molar ratio hydrogel with P(KA) concentrations as low as 0.65 wt% demonstrated low cytotoxicity and desirable cell adhesion towards fibroblasts and thus displayed a desirable combination of properties for wound healing application.
