Campaigne, E. published the artcileCyclization of ylidenemalononitriles. VIII. Synthesis of coumarins from o-methoxybenzylidenemalonitriles, Formula: C9H9NO2, the main research area is coumarin; malononitrile benzylidene cyclization; cyclization benzylidenemalononitrile.

The coumarins I (R = H, Cl; R1 = H, 6-,7-,8-MeO) were prepared by direct cyclization of α-cyano-o-methoxycinnamates (II) in H2SO4. Alkoxy groups other than the o-methoxy group involved in lactone formation are not hydrolyzed during the reaction. The 3-cyano group on the resulting coumarin is not hydrated in concentrated H2SO4, but can be converted to the carbamido group in 90% sulfuric acid. In certain cases these conditions do cleave methoxy substituents on the coumarins. The indenones III can be obtained by cyclizing the II with BF3.Et2O.

Yu, Yancheng published the artcileInsight into the binding mode of HIF-2 agonists through molecular dynamic simulations and biological validation, Recommanded Product: Phthalonitrile, the main research area is hypoxia inducible factor agonist mol dynamic simulation; Agonist; Binding mode; HIF-2; Molecular dynamic simulations.

Hypoxia-inducible factor-2 (HIF-2), a heterodimeric transcriptional protein consisting of HIF-2α and aryl hydrocarbon receptor nuclear translocator (ARNT) subunits, has a broad transcriptional profile that plays a vital role in human oxygen metabolism M1001, a HIF-2 agonist identified by high-throughput screening (HTS), is capable of altering the conformation of Tyr281 of the HIF-2α PAS-B domain and enhancing the affinity of HIF-2α and ARNT for transcriptional activation. M1002, an analog of M1001, shows improved efficacy than M1001. However, the cocrystal structure of M1001 and HIF-2 has some defects in revealing the agonist binding mode due to the relatively low resolution, while the binding mode of M1002 remained unexplored. To in-depth understand agonist binding profiles, herein, the mol. dynamic (MD) simulations was applied to construct a stable agonist-protein model, and a possible binding mode was proposed through the anal. of the binding free energy and hydrogen bonding of the simulation results. Nine compounds were then synthesized and evaluated to verify the proposed binding mode. Among them, compound 10 manifested improved agonistic activity and reduced toxicity compared to M1002. This study provides deep insight into the binding mode of such HIF-2 agonists, which would be useful for designing novel agonists for HIF-2.

Liu, Pingxian published the artcileDesign and synthesis of novel pyrimidine derivatives as potent antitubercular agents, Computed Properties of 1885-29-6, the main research area is ceritinib pyrimidine analog preparation antitubercular mol docking; Antimycobacterial; Ceritinib; Dihydrofolate reductase inhibitors; Pyrimidine derivatives.

The emergence of various drug-resistant Mycobacterium tuberculosis (Mtb) strains has necessitated the exploration of new drugs that lack cross-resistance with existing therapeutics. By screening the MedChemExpress bioactive compound library, ceritinib was identified as a compound with activity against Mtb H37Ra. Ceritinib had a MIC value of 9.0 μM in vitro and demonstrated in vivo efficacy in a BALB/c mouse model infected with autoluminescent H37Ra. Then, 32 novel ceritinib derivatives were synthesized, and their antimycobacterial activities were evaluated in vitro. The antimycobacterial activities of the synthesized compounds were drastically affected by substitutions at position 4 of the pyrimidine nucleus and were enhanced by the presence of 2-isopropoxy-5-methyl-4-(piperidin-4-yl)aniline at position 2 of the pyrimidine nucleus. The in vivo antitubercular activities of the three most potent compounds were evaluated. 5-Chloro-N2-(2-isopropoxy-5-methyl-4-(piperidin-4-yl) phenyl)-N4-(naph thalen-1-yl) pyrimidine-2,4-diamine (I) remarkably reduced the Mtb burden of mice. This result suggested the potential of I as a novel drug with superior antitubercular activities. The results of experiments on the combination of sulfamethoxazole with I and in silico modeling suggest that dihydrofolate reductase is the potential mol. target of I.

Yuan, Jie published the artcileActivating Intersystem Crossing and Aggregation Coupling by CN-Substitution for Efficient Organic Ultralong Room Temperature Phosphorescence, Category: nitriles-buliding-blocks, the main research area is activating intersystem crossing aggregation coupling cyano substitution phosphorescence.

Organic ultralong room-temperature phosphorescence (OURTP) has boomed recent advances of organic optoelectronics with the significant breakthrough in facilitating the intersystem crossing and stabilization of triplet excitons of purely organic materials. However, it remains a challenge in revealing the inherent mechanism of OURTP and the general mol. design principles of OURTP materials have yet to be reached, largely owing to the rather complicated and varied OURTP mol. structures. Here, we propose a facile strategy to design efficient OURTP materials by simply introducing a cyano group (CN) on benzene. On the basis of these very simple OURTP mols., it was found that the simultaneously enhanced intersystem crossing and aggregation coupling are two intrinsic prerequisites in realizing the efficient OURTP. The first observation of the excimer emission from the stabilized singlet excited states offers an important evidence for the mechanism study of OURTP, and the direct CN substitution on the benzene ring would be highly instructive for designing efficient OURTP mols.

Galstyan, Anzhela published the artcileExploring the Impact of Coordination-Driven Self Assembly on the Antibacterial Activity of Low-Symmetry Phthalocyanines, COA of Formula: C8H4N2, the main research area is phthalocyanine coordination driven self assembly antimicrobial photodynamic therapy; antimicrobial photodynamic therapy; bacterial biofilm; pH-responsiveness; phthalocyanine; self-assembly.

Understanding the action mechanisms of self-assembled photosensitizers is very important to determine the requirements that constructing monomers should fulfill to obtain nanostructures with the desired function. Here, the synthesis, supramol. aggregation tendency, photophys. properties and antimicrobial photodynamic activity of low symmetry metal-free phthalocyanine is carefully examined and compared with its metalated counterpart. When exposed to the media with different pH values striking differences in the self-assembly of these two derivatives were observed Equilibrium between active and inactive forms of this unique supramol. system were shifted upon change of the microenvironment influencing its biol. activity against Gram-pos. and Gram-neg. bacteria in planktonic and biofilm state. DFT calculations helped to explain possible differences in the aggregate formation, showing that metal-ligand interaction is a key process behind the higher activity of metalated derivative These results point out the importance of intermol. interactions between photosensitizers, which is essential to guide the design of self-assembled phototheranostic agents with improved performance.
