Practical synthesis of maleimides and coumarin-linked probes for protein and antibody labelling via reduction of native disulfides

The cellular tracking, detection and sensing of protein or antibody movement are important aspects to advance our understanding of biomolecular interactions and activity. Antibodies modified with fluorescent dyes are also valuable tools, especially in immunology research. We describe here a proof-of-principle study of a new water-soluble coumarin probe with a maleimide thiol-reacting unit to fluorescently tag biomolecules. Highlights include: (1) a convenient water-based preparation of N-substituted maleimides, (2) a one-pot preparation of activated maleimido-esters, and (3) a bio-conjugation protocol for the selenol-promoted reduction of native disulfide bonds and the ‘site-specific’ labelling of antibodies with no significant loss of activity.

Identification of an anti-inflammatory derivative with anti-cancer potential: The impact of each of its structural components on inflammatory responses in macrophages and bladder cancer cells

Inflammation plays a crucial role in many types of cancer and is known to be involved in their initiation and promotion. As such, it is presently recognized as an important risk factor for several types of cancers such as bladder, prostate and breast cancers. The discovery of novel anti-inflammatory compounds can have a huge implication not only for the treatment of cancer but also as preventive and protective treatment modalities. We have recently identified a new compound (1) that presents interesting anti-inflammatory activity. In order to better understand its biological action, we have divided the molecule in its basic components and verified their respective contribution towards the anti-inflammatory response of the whole molecule. We have discovered that only the combination of the maleimide function together with the tert-butyloxycarbonylhydrazinamide function lead to important anti-inflammatory properties. The main derivative 1 can decrease the activating effects of INFgamma or IL6 on human (hMomegas) macrophages by 38% or by 64% at a concentration of 10 muM as indicated by a decrease of STAT1 or STAT3 activation. The expression of pro-inflammatory markers CD40 and MHCII in INFgamma stimulated hMomegas were reduced by 87% and 49%, respectively with a 3 h pretreatment of 1 at 10 muM. The cell motility assay revealed that 1 at 10 muM can reduce relative cell motility induced by IL6 by 92% in comparison with the untreated control hMomega monolayers. Compound 1 reduced by 91% the inflammatory response induced by the cytokines (INFgamma + TNFalpha) in the macrophage-like J774A.1 cells at a concentration of 25 muM, as measured by the detection of NO production with the Griess reagent. Furthermore, upon removal of the tert-butyloxycarbonyl protective group the unprotected derivative as a hydrochloride salt (1A) retains interesting anti-inflammatory activity and was found to be less toxic than the parent compound (1).

Elucidating the Origin of diastereoselectivity in a self-replicating system: Selfishness versus altruism

We have investigated a diastereoselective self-replicating system based on a cycloaddition of a fulvene derivative and a maleimide using a two-pronged approach of combining NMR spectroscopy with computational modelling. Two diastereomers are formed with identical rates in the absence of replication. When replication is enabled, one diastereomer takes over the resources as a “selfish” autocatalyst, while exploiting the competitor as a weak “altruist”, resulting in a diastereoselectivity of 16:1. We applied 1D and 2D NMR spectroscopic techniques supported by ab initio chemical shifts as well as ab initio molecular dynamics simulations to study the structure and dynamics of the underlying network. This powerful combination allowed us to decipher the energetic and structural rationale behind the observed behaviour, while static computational methods currently used in the field did not.

Biodegradable synthetic polymers: Preparation, functionalization and biomedical application

Biodegradable polymers have been widely used and have greatly promoted the development of biomedical fields because of their biocompatibility and biodegradability. The development of biotechnology and medical technology has set higher requirements for biomedical materials. Novel biodegradable polymers with specific properties are in great demand. Biodegradable polymers can be classified as natural or synthetic polymers according to the source. Synthetic biodegradable polymers have found more versatile and diverse biomedical applications owing to their tailorable designs or modifications. This review presents a comprehensive introduction to various types of synthetic biodegradable polymers with reactive groups and bioactive groups, and further describes their structure, preparation procedures and properties. The focus is on advances in the past decade in functionalization and responsive strategies of biodegradable polymers and their biomedical applications. The possible future developments of the materials are also discussed.

Fumaria densiflora DC. Alkaloids

Twenty isoquinoline alkaloids were identified in the aerial part of Fumaria densiflora DC. In addition to bicuculline, densiflorine, fumaritine, fumariline, scoulerine, coptisine, cryptopine, parfumine, protopine, and sinactine which have been found previously, the following alkaloids were isolated for the first time from this species: adlumine, fumaricine, fumaritridine, fumarophycine, fumarofine, corytuberine, cis-N-methylstylopinium iodide, stylopine, and two new 1-benzylisoquinoline alkaloids, viz. fumaflorine and fumaflorine methyl ester. The cytoprotectivity of extracts of F. densiflora and F. officinalis, and that of protopine, cryptopine, and parfumine was tested on primary cultures of rat hepatocytes intoxicated with carbon tetrachloride. The cytoprotective effect of the extracts is associated with the alkaloids.

ENANTIOSELECTVE REACTIONS CATALYZED BY CHIRAL TRIAZOLIUM SALTS

This invention provides a convenient method for converting imines and other electrophiles into heterocyclic ring systems. The process does not require the use of metallic reagents, and is catalyzed by an organic heterocyclic carbene catalyst. Accordingly, it produces the desired compounds without the concomitant production of a large volume of metallic waste. Chiral heterocyclic carbene catalysts of the invention and methods of using these catalysts produce chiral heterocycles in high enantiomeric and diastereomeric excess.
