Four 2,4-disubstituted quinazoline series containing various amide moieties were designed and synthesized as new anti-influenza A virus agents using the strategies of bio-isosterism and scaffold hopping. Many of them exhibit potent in vitro anti-influenza A virus activity and low cytotoxicity (CC50: > 100 mu M). Particularly, compounds 10a5 and 17a show better activity (IC50: 3.70-4.19 mu M) and higher selective index (SI: > 27.03, > 23.87, respectively) against influenza A/WSN/33 virus (H1N1), opening a new direction for quinazoline derivatives in anti-influenza A virus field.

An efficient and green protocol for synthesizing beta-acyloxyselenides was developed through the visible-light-induced difunctionalization of styrenes with a binary system of diaryldiselenides and carboxylic acids under mild reaction conditions, without using any transition-metal-catalysts. This protocol is scalable and tolerates a wide spectrum of styrenes and carboxylic acids to deliver the corresponding products in moderate to excellent yields, providing convenient approach to beta-acyloxyselenides.

The use of a methanesulfonic acid/triethylamine trihydrofluoride combination for the direct hydrofluorination of methallyl-containing substrates is reported. Under those metal-free conditions that use readily available, cheap, and easy to handle reagents, a range of methallyl alkenes could be converted to their corresponding tertiary fluoride in up to 78% yield. Finally, a promising result for the adaptation of this chemistry to continuous flow conditions is reported.

The preparation of substituted azetidines and larger ring, nitrogen-containing saturated heterocycles is enabled through efficient and selective intermolecular sp(3)-C-H amination of alkyl bromide derivatives. A range of substrates are demonstrated to undergo C-H amination and subsequent sulfamate alkylation in good to excellent yield. N-Phenoxysulfonyl-protected products can be unmasked under neutral or mild basic conditions to yield the corresponding cyclic. secondary amines. The preparative convenience of this protocol is demonstrated through gram-scale and telescoped multistep procedures. Application of this technology is highlighted in a nine-step total synthesis of an unusual azetidine-containing natural product, penaresidin B.

Oxidative stress plays vital roles in virous neurodegenerative diseases including Alzheimer’s disease. Activation of the transcription factor Nrf2 (nuclear factor erythroid 2-related factor 2), the key regulator of oxidative stress, may provide a new therapeutic strategy for these diseases. Herein we synthesized and evaluated a series of 1,3,4-oxa/thiadiazole core Nrf2 activators as neuroprotective agents. The representative compound 8 exhibited cytoprotective and Nrf2 activation effects in a neuron-like PC-12 cells. Additionally, compound 8 showed good membrane permeability, indicating this compound could penetrate blood-brain barrier (BBB) to reach central nervous system (CNS) as a neuro-protective agent. These results indicated that these Nrf2 activators with 1,3,4-oxa/thiadiazole core could serve as a new chemotype against oxidative stress in neurodegenerative diseases.

A porous cross-linked poly (ethyleneamine)-polysulfonamide (PEA-PSA) as a novel organic support system is synthesized in the presence of silica template by nanocasting technique. The paper demonstrates immobilization of CuI nanoparticles inside the pores (PEA-PSA@CuI) for the facile recovery and recycling of these nanoparticles. The presence of porous PEA-PSA and PEA-PSA@CuI nanocomposites was confirmed using FT-IR spectroscopy, FE-SEM, EDX, TGA, XRD, TEM, BET, XPS, WDX, H-1 NMR, and ICP-OES techniques. The PEA-PSA@CuI along with Ag(I)/K2S2O8 was implemented as a reusable cooperative catalyst-oxidant system in the N-arylation of p-toluenesulfonamide with substituted carboxylic acids in mild condition. So, the novel decarboxylative cross-coupling catalyzed by copper and silver has been developed. Aromatic, secondary and tertiary aliphatic acids underwent high efficient decarboxylative processes with p-toluenesulfonamide to afford the corresponding products. This method provides a practical approach for the flexible synthesis of sulfonamides from the readily affordable substrates. The catalyst is highly reusable and efficient, especially in terms of time and yield of the desired product.

A novel series of a hybrid class of hybrid thiazolidin-4-one derivatives were designed and synthesized through one-pot catalytic synthesis. The reaction was catalyzed in the presence of silica-H(2)SO4((+6)). The derivatives computational ADMET profile was calculated. The study shows that most active derivatives have optimal logP, higher anti-inflammatory activity score, and poor metabolism at the sight of P450-3A4 and 2D6. The entire series of derivatives were further evaluated for anti-tubercular (against Mycobacterium tuberculosis H37Rv (Resistant strain)) and anti-inflammatory activity (in-vivo assay using Wistar rat). The result showed that derivatives 4c, 4h, and 4m have significant potency against tested M. tuberculosis. However, derivatives 4i and 4j found significantly active against inflammation. In vitro COX inhibition assay also supported the result in favor of selectivity and efficacy of derivatives. [GRAPHICS] .

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.
