A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters and arylboronic acids as coupling partners was developed. This methodology provides a heterogeneous catalytic route for aryl ketone formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS analysis of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd-0/Pd-II catalytic cycle that began with Pd-0.

We report a new application of N-amino-7-azaindole as a new bidentate-directing group for [Ru(p-cymene)Cl-2](2)-catalyzed C(sp(2))-H alkenylation/annulation of N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamides with internal alkynes to afford N-isoquinolono-7-azaindole via the formation of C-C and C-N bonds. The reaction shows a wide range of substrate scope with different symmetrical and unsymmetrical alkynes, affording the desired product in good to excellent yields. In the case of unsymmetrical alkynes, a highly regioselective product was obtained, which was confirmed by single-crystal X-ray crystallography. A new ruthenium-4-methyl-N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamide complex was isolated, and its structure was confirmed by single-crystal X-ray crystallography.

BACKGROUND: Transitional care programs (TCPs) coordinate care to improve safety and efficiency surrounding hospital discharge. While TCPs have the potential to reduce hospital length of stay and readmissions, their financial implications are less well understood. OBJECTIVE: To perform a cost-benefit analysis of a previously published neurosurgical TCP implemented at an urban academic hospital from 2013 to 2015. METHODS: Patients received intensive preoperative education and framing of expectations for hospitalization, in-hospital discharge planning and medication reconciliation with a nurse educator, and a follow-up phone call postdischarge. The cost-benefit analysis involved program costs (nurse educator salary) and total direct hospital costs within the 30-d perioperative window including readmission costs. RESULTS: The average cost of the TCP was $435 per patient. The TCP was associated with an average total cost reduction of 17.2% (95% confidence interval [CI]: 7.3%-26.7%, P=.001). This decrease was driven by a 14.3% reduction in the average initial admission cost (95% CI: 6.2%-23.7%, P=.001), largely attributable to the 16.3% decrease in length of stay (95% CI: 9.93%-23.49%, P<.001). Thirty-day readmissions were significantly decreased in the TCP group, with a 5.5% readmission rate for controls and 2.4% for TCP enrollees (P=.04). The average cost of readmission was decreased by 71.3% (95% CI: 58.7%-74.7%, P<.01). CONCLUSION: This neurosurgical TCP was associated with decreased costs of initial admissions, 30-d readmissions, and total costs of hospitalization alongside previously published decreased length of stay and reduced 30-d readmission rates. These results underscore the clinical and financial feasibility and impact of transitional care in a surgical setting. Application In Synthesis of 4-Nitrobenzoic acid.

Cyanobacterial pyruvate dehydrogenase multienzyme complex E1 (PDHc E1) is a potential target enzyme for finding inhibitors to control harmful cyanobacterial blooms. In this study, a series of novel triazole thiamin diphosphate (ThDP) analogs were designed and synthesized by modifying the substituent group of triazole ring and optimizing triazole-benzene linker as potential cyanobacterial PDHc E1 (Cy-PDHc E1) inhibitors. Their inhibitory activities against Cy-PDHc E1 in vitro and algicide activities in vivo were further examined. Most of these compounds exhibited prominent inhibitory activities against Cy-PDHc E1 (IC50 1.48-4.48 mu M) and good algicide activities against Synechocystis PCC6803 (EC50 0.84-2.44 mu M) and Microcystis aeruginosa FACHB905 (EC50 0.74-1.77 mu M). Especially, compound 8d showed not only the highest inhibitory activity against Cy-PDHc E1 (IC50 1.48 mu M), but also the most powerful inhibitory selectivity between Cy-PDHc E1 (inhibitory rate 98.90%) and porcine PDHc E1 (inhibitory rate only 9.54%). Furthermore, the potential interaction between compound 8d and Cy-PDHc E1 was analyzed by a molecular docking method and site-directed mutagenesis and enzymatic analysis and fluorescence spectral analysis. These results indicated that compound 8d could be used as a hit compound for further optimization and might have potential to be developed as a new algicide.

The reaction of 2-chloro-6,7-dimethoxy-3-nitroquinoline with a series of amines and aminoalkanoates under basic microwave-mediated conditions and under Buchwald-Hartwig amination conditions is reported. The microwave irradiation favored the reaction with amines, resulting in yields of up to 80%, whereas amino acid functionalization gave yields comparable to those of Buchwald-Hartwig amination. tert-Butyl (2R)-4-[(6,7-dimethoxy-3-nitroquinolin-2-yl)amino]-2-hydroxybutanoate was successfully cyclized to the pyoverdin chromophore, a subunit of siderophores.

The skeleton of the diterpene dehydroabietylamine was modified, and a set of 12-hydroxy-dehydroabietylamine derivatives was obtained. The compounds were screened in colorimetric Ellman’s assays to determine their ability to act as inhibitors for the enzymes acetylcholinesterase (AChE, from electric eel) and butyrylcholinesterase (BChE, from equine serum). Additional investigations concerning the enzyme kinetics were performed and showed 12-hydroxy-N-(4-nitro-benzoyl)dehydroabietylamine (13) and 12-hydroxy-N-(isonicotinoyl)dehydroabietylamine (17) as selective BChE inhibitors holding good inhibition constants K-i = 0.72 +/- 0.06 mu M and K-i = 0.86 +/- 0.19 mu M, respectively.

This work describes the use of kinetics as a tool for rational optimization of an esterification process with down to equimolar ratios of reagents using a recyclable commercially available zirconocene complex in catalytic amounts. In contrast to previously reported group IV metal-catalyzed esterification protocols, the work presented herein circumvents the use of water scavengers and perfluorooctane sulfonate (PFOS) ligands. Insights into the operating mechanism are presented.

The HDAC inhibitor 4-tert-butyl-N-(4-(hydroxycarbamoyl)phenyl)benzamide (AES-350, 51) was identified as a promising preclinical candidate for the treatment of acute myeloid leukemia (AML), an aggressive malignancy with a meagre 24% 5-year survival rate. Through screening of low-molecular-weight analogues derived from the previously discovered novel HDAC inhibitor, AES-135, compound 51 demonstrated greater HDAC isoform selectivity, higher cytotoxicity in MV4-11 cells, an improved therapeutic window, and more efficient absorption through cellular and lipid membranes. Compound 51 also demonstrated improved oral bioavailability compared to SAHA in mouse models. A broad spectrum of experiments, including FACS, ELISA, and Western blotting, were performed to support our hypothesis that 51 dose-dependently triggers apoptosis in AML cells through HDAC inhibition.
