Poisonous weeds are a global problem since they not only hinder local economic development, but also cause ecological harm. Consolida rugulosa (family Ranunculaceae) is a weed that is widespread in Northwestern China and causes severe poisoning when ingested by livestock. In the present study, we purified the toxins in this plant and investigated their mechanism of action. Five natural diterpene alkaloids (compounds 1-5)-including two new compounds (1 and 2)-were isolated, and five semi-synthetic derivatives (6-10) were synthesised based on 4 or 5 for structure-activity analysis. The toxicity of the compounds was evaluated in vitro with lactate dehydrogenase (LDH) assay. All of the compounds-especially 1-stimulated LDH release in primary cultured rat myocardial cells, an effect that was blocked by the Na+ channel blocker lidocaine. Electrocardiography revealed that rats treated with 1 had severe arrhythmia, while heart Doppler echocardiography and analysis of serum biomarkers levels revealed that administration of 1 for 15 days induced changes in cardiac structure and myocardial enzyme levels. These effects were antagonised by lidocaine treatment. Thus, diterpene alkaloids are the main compounds responsible for the cardiotoxicity of C. rugulosa, which can be mitigated by co-administration of lidocaine.

An operationally simple isothiourea-catalysed acylative kinetic resolution of unprotected 1,1 ‘-biaryl-2,2 ‘-diol derivatives has been developed to allow access to axially chiral compounds in highly enantioenriched form (s values up to 190). Investigation of the reaction scope and limitations provided three key observations: i) the diol motif of the substrate was essential for good conversion and high s values; ii) the use of an alpha,alpha-disubstituted mixed anhydride (2,2-diphenylacetic pivalic anhydride) was critical to minimize diacylation and give high selectivity; iii) the presence of substituents in the 3,3 ‘-positions of the diol hindered effective acylation. This final observation was exploited for the highly regioselective acylative kinetic resolution of unsymmetrical biaryl diol substrates bearing a single 3-substituent. Based on the key observations identified, acylation transition state models have been proposed to explain the atropselectivity of this kinetic resolution.

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.

An asymmetric [3 + 2] formal cycloaddition reaction between oxindole alpha-keto esters and enals has been developed. This alpha,gamma-regioselective reaction afforded multifunctional carbocyclic oxindoles via dienamine-enamine cascade reaction followed by isomerization. Furthermore, a highly enantioselective Diels-Alder reaction was demonstrated between 2,4-dienals and oxindole alpha-keto esters via trienamine intermediates. Chiral secondary amine catalyzed the both reactions under mild conditions and the cyclized products were isolated in moderate to good yields with good diastereoselectivities (>20:1 dr) and enantioselectivities (up to 99 %).

We report the first highly enantio- and diastereoselective three-component Povarov reaction between anilines and aldehydes catalyzed by a chiral amine catalyst. A wide variety of substituted tetrahydroquinolines were obtained with moderate to good yields and excellent enantioselectivity and diastereoselectivity (up to 99% ee and >95:5 dr) under the reaction conditions. Furthermore, the reaction intermediates could be efficiently converted to other valuable building blocks.

Enantioselective formation of cyclohexene derivatives bearing an all-carbon quaternary stereogenic center is described. The racemic cyclohexenes are readily transformed to chiral substituted cyclohexenes in good yield with excellent enantioselectivity and diastereoselectivity by a palladium-mediated deracemization. The resulting products are promising synthetic intermediates of biologically active natural products. This protocol provides us with a new entry to the concise and scalable synthesis of multifunctionalized compounds.

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.

A selective synthesis of hydrazoarene from nitroarene and its application are reported. Using polystyrene (PS) resins as solid supports for Au nanoparticles (AuNPs), polystyrene-supported Au nanoparticles (AuNPs@PS) were synthesized and characterized. In the presence of AuNPs@PS (1.0 mol %) as a catalyst, nitroarenes afforded corresponding hydrazoarenes (up to 99%) with high selectivity (up to 100%) under mild reaction conditions (NaBH4, 50% aq. EtOH, and room temperature). Depending on the reaction conditions (the amount of NaBH4, the substituent of nitroarenes, and the sequential addition of HCl), nitroarenes were converted to corresponding azoarenes (up to 95%), aminoarenes (up to 99%), and 4,4′-diaminobiaryls (up to 99%). Our easily recyclable catalytic system using a solid-phase reaction vessel provides an attractive synthetic method in an eco-friendly and sustainable manner.

The new potentially best-in-class beta-lactamase inhibitor IID572 was discovered by a late-stage functionalization approach. An alternative synthesis was developed to satisfy the short-term material need for toxicological studies in animals. The new synthetic strategy was built on two key features, an intramolecular azomethine ylide [3 + 2] cycloaddition that allowed the efficient formation of molecular complexity from readily available starting materials and an enzymatic resolution that resulted in high optical purity of a key intermediate.
