Trowse, Benjamin R.;Byrne, Fergal P.;Sherwood, James;O’Brien, Peter;Murray, Jane;Farmer, Thomas J. research published 《 Study on 2,2,5,5-Tetramethyloxolane (TMO) as a Solvent for Buchwald-Hartwig Aminations》, the research content is summarized as follows. Herein, the successful application of 2,2,5,5-tetramethyloxolane (TMO), a solvent with a similar property profile to toluene, for Buchwald-Hartwig amination reactions for coupling a wide range of primary and secondary amines with aryl bromides was demonstrated. When NaOt-Bu was used as the base, similar yields were obtained in toluene and TMO. In contrast, using Cs₂CO₃, TMO outperformed toluene significantly for electron-deficient aryl bromides that could be susceptible to nucleophilic attack. To showcase the use of TMO as a solvent for Buchwald-Hartwig aminations, the synthesis of a key intermediate in the route to smoothened (SMO) receptor antagonist drug candidate SEN826 was successfully accomplished in TMO. Improved metrics and reduction in residual palladium in the isolated amines demonstrate further benefits in the substitution of toluene with TMO in Buchwald-Hartwig aminations.

A series of new coumarin-imidazo[1,2-a]heterocyclic-3-acrylate derivatives were synthesized by the Heck reaction between the corresponding 3-(imidazo[1,2-a]pyrimidines)-(2-yl)-2H-chromenones and Me acrylate in 45-87% yields. The effect of the distinct substituents on third-order nonlinear optical properties was examined, exptl. measuring their nonlinear refractive indexes by the Z-scan technique. D. functional theory (DFT) and time-dependent DFT were utilized with the B3LYP, CAM-B3LYP, PBE (PBEPBE), and M062X functionals on Gaussian09 software to calculate the vertical excitation, relaxation of the brightest excited states, conformation, HOMO-LUMO gaps, oscillator strength, polarizability, and hyperpolarizabilities of all derivatives The acrylates showed a nonlinear response at a certain level of power, the compounds bearing a diethylamino electron-donating group exhibited higher nonlinear refractive index values (~10^-9 cm² W^-1), which is in agreement with the trend in the computational calculations of the first and second hyperpolarization. According to the structural anal., the electron-withdrawing group (acrylate) is mainly responsible for the loss of coplanarity because of increasing the dihedral angle between the coumarin and imidazo[1,2-a]heterocyclic moieties (to 39.1°). The unsubstituted 7-(diethylamino)-3-(imidazo[1,2-a]pyridin-2-yl)-2H-chromen-2-one presented the greatest nonlinearity due to its almost coplanar structure (n₂~10^-8 cm² W^-1), highlighting the importance of this feature.

The synthesis of 1,2,3-triazoles with immobilized Cu(I) in thiosemicarbazide-functionalized β-cyclodextrin (Cu@TSC-β-CD) as a supramol. catalyst was discussed. The catalyst was characterized by Fourier-transform IR spectroscopy (FT-IR), thermogravimetric anal. (TGA), X-ray diffraction (XRD), SEM, energy-dispersive X-ray spectroscopy (EDS), and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) measurements. The catalyst showed high activity (up to 95% yields of triazole products under optimized reaction conditions), providing a one-pot, atom-economic, and highly regioselective green method for 1,2,3-triazoles synthesis in an azide-alkyne cycloaddition (AAC) protocol in water. High stability and no appreciable leaching of Cu(I) were observed, owing to its strong binding via the coordination with thiosemicarbazide functionality.

Herein, we report two promising compounds 30 and 36 possessing nanomolar FLT3 inhibitory activities (IC₅₀ = 1.5-7.2 nM), high selectivity over c-KIT (>1000-fold), and excellent anti-AML activity (MV4-11 IC₅₀ = 0.8-3.2 nM). Furthermore, these two compounds efficiently inhibited the growth of multiple mutant BaF3 cells expressing FLT3-ITD, FLT3-D835V/F, FLT3-F691L, FLT3-ITD-F691L, and FLT3-ITD-D835Y. Oral administration of 30 and 36 at 6 mg/kg/d could significantly suppress tumor growth in the MV4-11 cell-inoculated xenograft model, exhibiting tumor growth inhibitory rates of 83.5% and 95.1%, resp. Importantly, 36 could prolong the mouse survival time in the FLT3-ITD-TKD dual mutation syngeneic mouse model (BaF3-FLT3-ITD-D835Y) at a dose of 6 mg/kg p.o. bid/4W. No clear myelosuppression was observed in the treated group of 36 in the MPO strain of zebrafish, even at 10 μM. In summary, our data demonstrated that 36 may represent a promising candidate for the treatment of FLT3 mutant AML.

With the increasing incidence of antibiotic resistance, new antibacterial agents having novel mechanisms of action hence are in an urgent need to combat infectious diseases caused by multidrug-resistant (MDR) pathogens. Four novel series of substituted 9-arylalkyl-10-methylacridinium derivatives as FtsZ inhibitors were designed, synthesized and evaluated for their antibacterial activities against various Gram-pos. and Gram-neg. bacteria. The results demonstrated that they exhibited broad-spectrum activities with substantial efficacy against MRSA and VRE, which were superior or comparable to the berberine, sanguinarine, linezolid, ciprofloxacin and vancomycin. In particular, the most promising compound I showed rapid bactericidal properties, which avoid the emergence of drug resistance. However, I showed no inhibitory effect on Gram-neg. bacteria but biofilm formation study gave possible answers. Further target identification and mechanistic studies revealed that I functioned as an effective FtsZ inhibitor to alter the dynamics of FtsZ self-polymerization, which resulted in termination of the cell division and caused cell death. Further cytotoxicity and animal studies demonstrated that I not only displayed efficacy in a murine model of bacteremia in vivo, but also no significant hemolysis to mammalian cells. Overall, this compound with novel skeleton could serve as an antibacterial lead of FtsZ inhibitor for further evaluation of drug-likeness.

The desfluoroquinolone-based hybrids with involvement of C-7 aminopyrimidine functional group were designed and synthesized. The biol. results showed majority of these hybrids still demonstrated potent anti-MRSA activity with MIC values between 0.38 and 1.5μg/mL, despite the lack of the typical C-6 fluorine atom. Particularly, the most active 1-cyclopropyl-7-((4-(3,4-dimethylphenoxy)pyrimidin-2-yl) amino)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid exhibited activities at submicromolar concentrations against a panel of MRSA strains including vancomycin-intermediate strains, levofloxacin-resistant isolates, and linezolid-resistant isolates, etc. As expected, it also displayed highly selective toxicity toward bacterial cells and low hERG inhibition. Further resistance development study indicated MRSA is unlikely acquired resistance against 1-cyclopropyl-7-((4-(3,4-dimethylphenoxy)pyrimidin-2-yl)amino)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid. The docking study revealed that two hydrogen bonds were formed between the C-7 substituent and the surrounding DNA bases, which contributed to resistance by reducing the dependence on the magnesium-water bridge interactions with topoisomerase IV. These indicated a promising strategy for developing new antibiotic quinolones to combat multidrug resistance and cardiotoxicity was resulted.

Song, Yan-Ling;Li, Bei;Xie, Zhen-Biao;Wang, Dan;Sun, Hong-Mei research published 《 Iron-Catalyzed Oxidative Amination of Benzylic C(sp³)-H Bonds with Anilines》, the research content is summarized as follows. Iron-catalyzed oxidative amination of benzylic C(sp³)-H bonds with anilines bearing electron-withdrawing groups (EWGs) or electron-donating groups (EDGs) has been realized based on simple variations of N-substituents on imidazolium cations in novel ionic Fe(III) complexes. The structural modification of the imidazolium cation resulted in regulation of the redox potential and the catalytic performance of the iron metal center. Using DTBP as oxidant, [HItBu][FeBr₄] (1,3-di-tert-butylimidazolium iron tetrabromide) showed the highest catalytic activity for anilines bearing EWGs, while [HIPym][FeBr₄] (1,3-bis(pyrimidin-2-yl)imidazolium iron tetrabromide) was more efficient for EDG-substituted anilines. This work provides an alternative access to benzylamines, e.g., RN(R¹)CH₂Ph [R = 4-O₂NC₆H₄, 2-pyrimidinyl, 8-isoquinolinyl, etc., R¹ = H, Me,], with advantages of both a wide substrate scope and iron catalysis.
