Despite considerable achievements in the hydrogenation of aromatic hydrocarbons over the past few years, the ability to hydrogenate arene or heteroarene rings in a highly selective manner in the presence of other reducible sites or without harming the remaining mol. structure has long been a major challenge. Such chemoselectivity and functional group tolerance is highly desirable for enabling direct access to key building blocks of polymers and pharmaceutical agents. For achieving such high selectivity, the development of suitable catalysts is of central importance. Herein, we report a convenient method for the scalable preparation of ruthenium oxide (RuO₂) nanoparticles supported on pine needle char (PNC) by simple impregnation of ruthenium salt on unactivated PNC, a solid byproduct (biochar) obtained in the slow pyrolysis of biomass pine needles. The resulting RuO₂-based nanocatalyst (RuO₂@PNC) exhibited remarkable activity and high selectivity for the hydrogenation of more than 50 challenging arenes and heteroarenes, including biomass-derived aromatic compounds (e.g., 4-n-propylphenol, furfuryl alc., and 2-Me furan). The synthetic value of this transformation is showcased for the hydrogenation of arene mixture present in petroleum refineries or coal tars as well as biomass-derived oils (bio-oils) with enriched furfural, ether, and phenol derivatives Under optimized conditions, the performance of this new catalyst was compared with state-of-the-art com. catalysts such as Ru/C, Pd/C, and Raney nickel and found that RuO₂@PNC is more superior and selective. Furthermore, the catalyst is easily recovered and reused up to four cycles. Biocarbon supported RuO₂-based catalyst exhibited remarkable activity and selectivity for clean hydrogenation of arenes and heteroarenes.

Kaur, Ravneet published the artcileBiodegradation of Butachlor by Bacillus altitudinis and Identification of Metabolites, Name: 2-Chloroacetamide, the publication is Current Microbiology (2020), 77(10), 2602-2612, database is CAplus and MEDLINE.

Butachlor is a chloroacetamide pre-emergence herbicide, with a half-life of 1.6 to 29 days. It is a suspected carcinogen, genotoxin, neurotoxin and persists in the environment having toxic effect on living systems. Butachlor degrading bacterial strain A16 was isolated from coal tar contaminated soil, which showed 99.38% similarity with Bacillus altitudinis 41KF2b^T as revealed by 16S rRNA anal. B. altitudinis strain A16 utilized butachlor as a sole source of carbon and degraded 90% of 50 mg L^-1 butachlor in 5 days at a rate constant and half-life (t_1/2) of 0.02 h^-1 and 34.65 h, resp., following the first-order reaction kinetics. Five metabolites (N-(butoxymethyl)-N-(2-chloroethyl)-2,6-diethylaniline, (N-(butoxymethyl))-2-chloro-N-(2-ethylphenyl) acetamide, N-(butoxymethyl)-2,6-diethyl-N-propylaniline, 2-chloro-N-(2,6-diethylphenyl) acetamide and 2,6-diethylaniline) were produced during the breakdown of butachlor by B. altitudinis A16 as identified by GC-MS anal., which are further mineralized to carbon dioxide and water. A metabolic pathway is proposed and compared with other bacteria. The findings have immense beneficial application since such microbes can be used on large scale for faster soil bioremediation and minimizing neg. impact of pesticide butachlor on health and environment.

In a previous study, the authors identified 3-alkyl-1,5-diaryl-1H-1,2,4-triazoles, e.g., I, to be a novel class of cannabinoid type-1 (CB₁) receptor antagonists. However, the synthesis yields for the ligands were low. An alternative synthesis pathway with improved yields is presented here. In addition, they have synthesized new structural derivatives and studied their results in competitive radioligand binding assays for cannabinoid receptors.

Rothlingshofer, Manuel published the artcileNucleic Acid-Templated Energy Transfer Leading to a Photorelease Reaction and its Application to a System Displaying a Nonlinear Response, Safety of 2-(N-(2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)ethyl)-2-(2-(((benzhydryloxy)carbonyl)amino)-6-oxo-5H-purin-9(6H)-yl)acetamido)acetic acid, the publication is Journal of the American Chemical Society (2011), 133(45), 18110-18113, database is CAplus and MEDLINE.

The photocleavage of a nitrobenzyl-type linker (NPPOC) at 405 nm wavelength was enabled by nucleic acid-templated energy transfer from a sensitizer (thioxanthenone) to the linker. This strategy was used to release profluorescent rhodamine, which facilitated monitoring of the reaction via fluorescence measurement in a nonoverlapping window with the sensitizer/photocleavage reaction. The rate acceleration of the templated reaction was greater than 20-fold over the background reaction. The templated reaction was used in conjunction with strand displacement to design four-component systems that responded to an analyte (DNA). Programming a specific hierarchical relationship among the four components enabled the design of a system that responded first pos. and then neg. to increasing levels of an analyte.

Huang, Kuo-Ting published the artcileCombinatorial Self-Assembly of Glycan Fragments into Microarrays, Recommanded Product: 2-(N-(2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)ethyl)-2-(2-(((benzhydryloxy)carbonyl)amino)-6-oxo-5H-purin-9(6H)-yl)acetamido)acetic acid, the publication is ChemBioChem (2011), 12(1), 56-60, database is CAplus and MEDLINE.

We have demonstrated that complex glycan arrays can be accessed through the combinatorial self assembly of PNA-encoded carbohydrate fragments. Although the use of DNA microarrays to sort carbohydrate-DNA conjugates had previously been reported, previous efforts were restricted to monosaccharides and did not explore a broad range of glycan structures, nor their combinatorial assembly. The cooperativity of the fragments in their interaction with carbohydrate-binding proteins was demonstrated with two different lectins. The binding profile showed the strongest interaction for discrete combinations of two fragments. Importantly, the PNA-tagged glycans can be readily prepared from native oligosaccharides obtained from natural or com. sources by conversion of the anomeric position into a thiol on a mg scale by a two- to three-step process. The simplicity of the protocols described should make glycan arrays more broadly accessible. Immobilization of glycans by hybridization offers a reliable approach by which to obtain a homogeneous distribution of ligands within a microarray spot and allows the use of microarrays with higher d. than accessible by contact printing, which is currently the standard practice. Last but not least, combinatorial self assembly of fragments on DNA microarrays should be broadly applicable beyond the glycan fragments described here.

Hill, Timothy A. published the artcileInhibition of Dynamin Mediated Endocytosis by the Dynoles-Synthesis and Functional Activity of a Family of Indoles, SDS of cas: 15029-36-4, the publication is Journal of Medicinal Chemistry (2009), 52(12), 3762-3773, database is CAplus and MEDLINE.

Screening identified two bisindolylmaleimides as 100 μM inhibitors of the GTPase activity of dynamin I. Focused library approaches allowed development of indole-based dynamin inhibitors called dynoles. 100-Fold in vitro enhancement of potency was noted with the best inhibitor, 2-cyano-N-octyl-3-[1-(3-dimethylaminopropyl)-1H-indol-3-yl]-acrylamide (dynole 34-2), a 1.3 ± 0.3 μM dynamin I inhibitor. Dynole 34-2 potently inhibited receptor mediated endocytosis (RME) internalization of Texas red-transferrin. The rank order of potency for a variety of dynole analogs on RME in U2OS cells matched their rank order for dynamin inhibition, suggesting that the mechanism of inhibition is via dynamin. Dynoles are the most active dynamin I inhibitors reported for in vitro or RME evaluations. Dynole 34-2 is 15-fold more active than dynasore against dynamin I and 6-fold more active against dynamin mediated RME (IC₅₀ ∼15 μM; RME IC₅₀ ∼80 μM). The dynoles represent a new series of tools to better probe endocytosis and dynamin-mediated trafficking events in a variety of cells.

Tomlin, Frederick M. published the artcileSite-specific incorporation of quadricyclane into a protein and photocleavage of the quadricyclane ligation adduct, COA of Formula: C11H22N2O4, the publication is Bioorganic & Medicinal Chemistry (2018), 26(19), 5280-5290, database is CAplus and MEDLINE.

The quadricyclane (QC) ligation is a bioorthogonal reaction between a quadricyclane moiety and a nickel bis(dithiolene) derivative Here we show that a QC amino acid can be incorporated into a protein site-specifically using the pyrrolysine-based genetic code expansion platform, and subsequently used for ligation chem. Addnl., we exploited the photolability of the QC ligation product to render the adduct cleavable with a handheld UV lamp. We further developed a protein purification method that involves QC ligation of biotin to a protein of interest, capture on streptavidin resin, and finally release using only UV light. The QC ligation thus brings novel chem. manipulations to the realm of bioorthogonal chem.

Selective synthesis of quinolines, e.g., I (R¹ = H, Me, MeO, Cl; R² = H, Me, MeO, Cl), has been achieved via oxidative annulation of functionalized pyridines with two alkyne mols. under Rh(III)-catalyzed cascade C-H activation of pyridines using Cu(OAc)₂ as an oxidant. The selectivity of this reaction is oxidant-dependent, particularly on the anion of the oxidant.

Li, Wanjing published the artcileEfficacy of angiotensin receptor neprilysin inhibitor in Asian patients with refractory hypertension, Product Details of C24H29N5O3, the publication is Journal of Clinical Hypertension (Hoboken, NJ, United States) (2022), 24(4), 449-456, database is CAplus and MEDLINE.

Sacubitril/valsartan, simultaneously inhibits neprilysin and angiotensin II receptor, showed an effect in reducing blood pressure (BP). The authors aimed to study whether it can be used as an antihypertensive agent in patients with refractory hypertension who have already been treated. A total of 66 Chinese patients with refractory hypertension were enrolled. Patients received sacubitril/valsartan 200 instead of angiotensin II receptor blocker or angiotensin converting enzyme inhibitor while other agents continued. If BP was uncontrolled after 4 wk, sacubitril/valsartan was increased to 400 mg. The BP reduction was evaluated by office BP and ambulatory BP monitoring after 8-wk treatment. The baseline office BP and mean arterial pressure (MAP) were 150.0/95.0 mmHg and 113.3 mmHg. BP and MAP reduced to 130.6/83.2 mmHg and 99.0 mmHg at week 8. Office BP and MAP reductions were 19.4/11.8 mmHg and 14.3 mmHg at endpoint (all p < .001). The 24-h, daytime and nighttime ambulatory BP were 146.2/89.1, 148.1/90.3, and 137.5/83.7 mmHg, resp. at baseline, and BP reduced to 129.6/79.8, 130.6/81.1, and 121.7/75.8 mmHg, resp. at week 8. The 24-h, daytime and nighttime ambulatory BP reductions were 16.6/9.3, 17.5/9.2, and 15.8/7.9 mmHg, resp. at endpoint (all p < .001). Sacubitril/valsartan significantly reduced office and ambulatory BP in refractory hypertension patients. Author study provided new evidence for sacubitril/valsartan in refractory hypertension.
