Raimundo, Brian C.; Oslob, Johan D.; Braisted, Andrew C.; Hyde, Jennifer; McDowell, Robert S.; Randal, Mike; Waal, Nathan D.; Wilkinson, Jennifer; Yu, Chul H.; Arkin, Michelle R. published the artcile< Integrating Fragment Assembly and Biophysical Methods in the Chemical Advancement of Small-Molecule Antagonists of IL-2: An Approach for Inhibiting Protein-Protein Interactions>, Recommanded Product: Methyl 2,3-dichlorobenzoate, the main research area is interleukin 2 receptor antagonist drug design.

Fragment assembly has shown promise for discovering small-mol. antagonists for difficult targets, including protein-protein interactions. Here, the authors describe a process for identifying a 60 nM inhibitor of the interleukin-2 (IL-2)/IL-2 receptor (IL-2Rα) interaction. By use of fragment-based approaches, a compound with millimolar affinity was evolved to a hit series with low micromolar activity, and these compounds were optimized into a lead series with nanomolar affinity. Fragment assembly was useful not only for hit identification, but also for lead optimization. Throughout the discovery process, biophys. methods and structural biol. demonstrated that compounds bound reversibly to IL-2 at the IL-2 receptor binding site.

Ju, Changha; Park, Chanhyuk; Kim, Taehyung; Kang, Shinwoo; Kang, Hyo published the artcile< Thermo-responsive draw solute for forward osmosis process; poly(ionic liquid) having lower critical solution temperature characteristics>, Synthetic Route of 1592-20-7, the main research area is polyvinylbenzyltributylammonium hexanesulfonate osmosis viscosity water desalination.

We synthesized poly(4-vinylbenzyltributylammonium hexanesulfonate) (P[VBTBA][HS]), a poly(ionic liquid) that shows lower critical solution temperature (LCST), via the anion exchange reaction of poly(4-vinylbenzyltributylammonium chloride) (P[VBTBA][Cl]) with sodium hexanesulfonate in order to investigate its suitability as a draw solute for the forward osmosis (FO) process. P[VBTBA][Cl] was obtained by the free radical polymerization of (4-vinylbenzyltributylammonium chloride [VBTBA][Cl]) monomer acquired by the Menshutkin reaction. The FO performance and recovery properties of the synthesized materials were systematically investigated. For example, the LCST of P[VBTBA][HS] was observed to be ∼17°C at 20 wt%, while no LCST was observed for [VBTBA][Cl] monomer and P[VBTBA][Cl] polymer before the anion exchange reaction, indicating that P[VBTBA][HS] can be recovered from the aqueous solution by heating it to above its LCST. Moreover, in an active layer facing the feed solution (AL-FS) system containing 20 wt% aqueous P[VBTBA][HS] solution at 15°C, the water flux and reverse solute flux of P[VBTBA][HS] were found to be ∼5.85 L m-2 h-1 and 1.13 g m-2 h-1, resp. Therefore, we studied the feasibility of using the poly(ionic liquid), a homopolymer having LCST characteristics, as a draw solute in the FO process.

Enzymes involved in RNA capping of SARS-CoV-2 are essential for the stability of viral RNA, translation of mRNAs, and virus evasion from innate immunity, making them attractive targets for antiviral agents. In this work, we focused on the design and synthesis of nucleoside-derived inhibitors against the SARS-CoV-2 nsp14 (N7-guanine)-methyltransferase (N7-MTase) that catalyzes the transfer of the Me group from the S-adenosyl-L-methionine (SAM) cofactor to the N7-guanosine cap. Seven compounds out of 39 SAM analogs showed remarkable double-digit nanomolar inhibitory activity against the N7-MTase nsp14. Mol. docking supported the structure-activity relationships of these inhibitors and a bisubstrate-based mechanism of action. The three most potent inhibitors significantly stabilized nsp14 (ΔTm ≈ 11°C), and the best inhibitor demonstrated high selectivity for nsp14 over human RNA N7-MTase.

The influence of both electron-withdrawing and electron-donating substituents such as nitro, nitrile, chloro, bromo and methoxy at C-3 on fluorobenzenes for their palladium-catalyzed direct C-2 arylation was explored. With electron-withdrawing substituents, the reaction proceeds nicely using 2-4 mol% of an air-stable palladium complex and potassium pivalate/dimethylacetamide (PivOK/DMA) as catalytic system; and in general, a very regioselective arylation at C-2 was observed Moreover, a variety of substituents on the aryl bromide coupling partner, such as benzoyl, formyl, nitro, nitrile, chloro and Me, and also heteroaryl bromides were tolerated.

Respiratory syncytial virus (RSV) is the cause of one-fifth of all lower respiratory tract infections worldwide and is increasingly being recognized as a serious threat to patient groups with poorly functioning immune systems. Our approach to finding a novel inhibitor of this virus was to screen a 20 000-member diverse library in a whole cell XTT assay. Parallel assays were carried out in the absence of virus in order to quantify any associated cell toxicity. This identified 100 compounds with IC50’s less than 50 μM. A-33903 (18), a 1,4-benzodiazepine analog, was chosen as the starting point for lead optimization. This mol. was moderately active and demonstrated good pharmacokinetic properties. The most potent compounds identified from this work were A-58568 (47), A-58569 (44), and A-62066 (46), where modifications to the aromatic substitution enhanced potency, and A-58175 (42), where the amide linker was modified.

Potent DNA minor-groove binding antibacterials, e.g. I (R = aryl, heteroaryl), were designed based on the natural product distamycin A and synthesized, and their structure-activity relationship was investigated. These compounds have been shown to target A/T-rich sites within the bacterial genome and, as a result, inhibit DNA replication and RNA transcription. The optimization was focused on N-terminal aromatic heterocycles and C-terminal amines and resulted in compounds with improved in vivo tolerability and excellent in vitro antibacterial potency (MIC ≥ 0.031 μg/mL) against a broad range of Gram-pos. pathogens, including drug-resistant strains such as methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, and vancomycin-resistant Enterococcus faecalis. In a first proof-of-concept study, I (R = 3-chloro-2-thienyl) showed in vivo efficacy in a mouse peritonitis model against methicillin-sensitive S. aureus infection with an ED50 value of 30 mg/kg.

Sen, Sudeshna; Goodwin, Sean E.; Barbara, Pedro Verdia; Rance, Graham A.; Wales, Dominic; Cameron, Jamie M.; Sans, Victor; Mamlouk, Mohamed; Scott, Keith; Walsh, Darren A. published the artcile< Gel-Polymer Electrolytes Based on Poly(Ionic Liquid)/Ionic Liquid Networks>, Formula: C9H9Cl, the main research area is gel polymer electrolyte ionic liquid conductivity crosslinking membrane.

The use of elec. charged, polymerized ionic liquids (polyILs) offers opportunities for the development of gel-polymer electrolytes (GPEs), but the rational design of such systems is in its infancy. In this work, we compare the properties of polyIL/IL GPEs based on 1-butyl-3-(4-vinylbenzyl)imidazolium bis(trifluromethanesulfonyl)imide containing trapped ammonium-based protic ionic liquids (ILs) with an analogous series based on the elec. neutral host polymer 1-(4-vinylbenzyl)imidazole. The materials are synthesized by photopolymerizing ionic and neutral monomers in the presence of diethylmethylammonium trifluoromethanesulfonate, [dema][TfO], diethylmethylammonium trifluoroacetate, [dema][TFAc], and diethylmethylammonium bis[trifluoromethanesulfonyl]imide, [dema][Tf2N], resp. The resulting materials are characterized using electron microscopy, IR spectroscopy, thermal anal., Raman spectroscopy, and AC-impedance anal. Spectroscopic anal. confirms that the ILs are distributed throughout the polymers, unless the GPE also contains poly(diallyldimethylammonium) bis[trifluoromethanesulfonyl]imide, when separation of the components occurs. The polyIL/IL GPEs are more electrochem. and thermally stable, and up to six times more conductive, than the materials based on the neutral host. As a proof-of-concept demonstration, we show that polyIL/IL gels can be 3D printed using readily available 3D-printing hardware.

The catalyst-free electrochem. di- and trifluoromethylation/cyclization of N-substituted acrylamides was realized under external oxidant-free conditions. The strategy provides expedient access to fluoroalkylated oxindoles, e.g., I, and 3,4-dihydroquinolin-2(1H)-ones with ample scope and broad functional group tolerance by mild, direct electrolysis of sodium sulfinates in an undivided cell. Detailed mechanistic studies provided strong support for a SET-based reaction manifold.

Li, Tianming; Yao, Zhengjun; Zhou, Jintang published the artcile< Preparation and characterization of a novel composite of polythioetherimide/bismaleimide/2,2'-diallylbisphenol A>, COA of Formula: C8H3ClO3, the main research area is polythioetherimide bismaleimide diallylbisphenol composite preparation thermomech property.

A novel composite of polythioetherimide (PTEI)/bismaleimide (BMI)/2,2′-diallylbisphenol A (BA) was prepared Mech. measurements, dynamic thermomech. anal., and microanal. were conducted to assess the toughness and morphol. of the composite. Results demonstrate that the addition of PTEI has significant effects on the mech. properties of the BMI/BA system. Compared with the BMI/BA resin, the PTEI/BMI/BA system significantly improves the impact strength and bending strength, given an appropriate amount of PTEI. Scanning electron microscope (SEM) images and energy dispersive spectroscopy results show that PTEI is distributed uniformly in the PTEI/BMI/BA system and that the interfacial compatibility between the PTEI and BMI/BA phase is excellent. Thermogravimetric and dielec. analyses were also conducted to infer the thermal and dielec. properties of the composite. With a suitable addition of PTEI, the BMI/BA resin still exhibits good thermal resistance and dielec. constant and loss values of the blends still retain good stability in a frequency band from 10 MHz to 60 MHz. All these changes in properties are closely correlated with the addition of PTEI.
