A novel multicomponent reaction involving isoquinoline, allenoate and activated ketone

The reaction of isoquinoline and allenoate with activated ketone resulted in a novel three component reaction, affording [1,3]oxazino[2,3-alpha]isoquinoline derivatives in moderate yields along with moderate diastereoselectivities via 1,4-dipolar cycloaddition. It was also found that when isatins were used as substrates, the regioselectivity of cycloadducts was different from those using ethyl trifluoropyruvate as substrate. (C) 2013 Elsevier Ltd.

Inhibition of the bacterial surface protein anchoring transpeptidase sortase by isoquinoline alkaloids

The inhibitory activity of Coptis chinensis rhizome-derived material was evaluated against sortase, a bacterial surface protein anchoring transpeptidase, from Staphylococcus aureus ATCC 6538p and compared to that of four commercially available isoquinoline alkaloids. The biologically active constituent of C. chinensis extract was characterized as the isoquinoline alkaloid, berberine chloride, by spectral analysis. The isolate was a potent inhibitor of sortase, with an IC50 value of 8.7 mug/ml and had antibacterial activity against Gram-positive bacteria with a minimum inhibitory concentration (MIC) in the range of 50400 mug/ml. Among the four isoquinoline alkaloids tested, berberine chloride had strong inhibitory activity. These results indicate that berberine is a possible candidate for the development of a bacterial sortase inhibitor.

Racemic total synthesis and evaluation of the biological activities of the isoquinoline-benzylisoquinoline alkaloid muraricine

The first racemic total synthesis of the isoquinoline-benzylisoquinoline alkaloid muraricine is reported herein. Pharmacological characterization identified muraricine as a moderate inhibitor of P-glycoprotein, a crucial factor of multidrug resistance in cancer. When combined with vincristine, muraricine partly reversed the chemoresistance of vincristine-resistant leukemia cells at a nontoxic concentration. Furthermore, no cytotoxic effects on noncancerous human cells in therapeutically relevant concentrations were observed.

A Novel and Green Method for the Synthesis of Highly Substituted Isoquinoline Derivatives in Ionic Liquid

A series of new highly substituted isoquinoline derivatives was obtained from the reaction of 2-(1-substituted piperidin-4-ylidene)malononitrile, benzaldehyde and malononitrile or cyanoacetate in ionic liquid at 50 degrees C. This novel procedure was different from the previous method in the synthesis of isoquinoline using pyridine fragment as reactant to construct benzene ring, and as well as had the advantages of one-pot, mild and environmentally benign. A possible mechanism was proposed based on the further experimental results.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2038-03-1, in my other articles.

Isoquinoline alkaloids from Corydalis taliensis

Corydalis taliensis Franch is a perennial herb used for treatment of rheumatic arthritis, toothache, and hepatitis. The chemical investigation of this plant resulted in the isolation of a new compound, named taliensineside (1). Its structure was identified on the basis of spectral evidence. In addition, thirteen known isoquinoline alkaloids (2-14) were isolated and identified by spectroscopic analysis and comparison of their spectral data with those reported previously.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 521284-21-9. Safety of (R)-2-((4-Nitrophenethyl)amino)-1-phenylethanol hydrochloride.

Bromination of isoquinoline, quinoline, quinazoline and quinoxaline in strong acid

Bromination of benzazines and benzodiazines most often gives a mixture of products. In this paper, we show that isoquinoline (1) may be regioselectively monobrominated in concentrated H2SO4 using NBS or in CF3SO3H using N,N’-dibromoisocyanuric acid (DBI) to give 5-bromoisoquinoline (2). The bromination was found to be highly sensitive to the choice of brominating agent, acid, temperature and concentration. Quinoline. quinazoline and quinoxaline may be brominated likewise, although with the strong regioselectivity reserved to isoquinoline.
