Aryloxymaleimides for cysteine modification, disulfide bridging and the dual functionalization of disulfide bonds

Tuning the properties of maleimide reagents holds significant promise in expanding the toolbox of available methods for bioconjugation. Herein we describe aryloxymaleimides which represent ‘next generation maleimides’ of attenuated reactivity, and demonstrate their ability to enable new methods for protein modification at disulfide bonds.

Preparation and Characterization of Hetero-bifunctional Cross-linking Reagents for Protein Modifications

Ten aromatic and aliphatic cross-linking reagents of hetero-bifunctional type were synthesized as part of a search for useful reagents of this type.All of the reagents possess two selectively reactive groups a maleimide group which can combine with a thiol group via its double bond and an N-Hydroxysuccinimidyl ester (one of the most hydrophilic active esters), which can react with an ammmine group.It was found that the active esters of the reagents tested were mostly more reactive with lysine than with leucine, and acylated amino acids more rapidly at pH 8.0 than at pH 7.0.It was also found that the stability of the maleimide group in the compounds tested depends largely upon the pH of the buffer used.The most stable pH was 5.0-6.0.To use one of the present compounds as a cross-linker, the crystalline reagent should be dissolved in tetrahydrofuran of dioxane and the solution used for cross-linking.The acylation step should be carried out first with thiol addition to the maleimide group as the second step.The optimum pH of the buffer used for the first step is slightly basic.The reaction time should be limited to less than 1 hr.When the first step is over, the pH of the reaction mixture should be changed to 5.0-6.0.Keywords—cross-linker; hetero-bifunctional reagent; reactivity of N-hydroxy-succinimidyl ester; stability of maleimide residue; N-(maleimidobenzoyloxy)succinimide derivative; N-(maleimidoalkyloxy)succinimide derivative

Carbonic anhydrase inhibitors

At least 14 different carbonic anhydrase (CA, EC 4.2.1.1) isoforms were isolated in higher vertebrates, where these zinc enzymes play crucial physiological roles. Some of these isozymes are cytosolic (CA I, CA II, CA III, CA VII), others are membrane-bound (CA IV, CA IX, CA XII, and CA XIV), CA V is mitochondrial and CA VI is secreted in saliva. Three acatalytic forms are also known, which are denominated CA related proteins (CARP), CARP VIII, CARP X, and CARP XI. Several important physiological and physio-pathological functions are played by many CA isozymes, which are strongly inhibited by aromatic and heterocyclic sulfonamides as well as inorganic, metal complexing anions. The catalytic and inhibition mechanisms of these enzymes are understood in detail, and this helped the design of potent inhibitors, some of which possess important clinical applications. The use of such enzyme inhibitors as antiglaucoma drugs will be discussed in detail, together with the recent developments that led to isozyme-specific and organ-selective inhibitors. A recent discovery is connected with the involvement of CAs and their sulfonamide inhibitors in cancer: several potent sulfonamide inhibitors inhibited the growth of a multitude of tumor cells in vitro and in vivo, thus constituting interesting leads for developing novel antitumor therapies. Furthermore, some other classes of compounds that interact with CAs have recently been discovered, some of which possess modified sulfonamide or hydroxamate moieties. Some sulfonamides have also applications as diagnostic tools, in PET and MRI or as antiepileptics or for the treatment of other neurological disorders. Future prospects for drug design applications for inhibitors of these ubiquitous enzymes are also discussed.

A novel way to synthesize star polymers in one pot by ATRP of N-[2-(2-bromoisobutyryloxy)ethyl]maleimide and styrene

A one-pot approach to synthesize star polymers by atom transfer radical polymerization (ATRP) of N-[2-(2-bromoisobutyryloxy)ethyl]maleimide (BiBEMI) with a large excess of styrene (St) was described. It was based on preferential consumption of BiBEMI, as an inimer, through its copolymerization with St, to form a branched intermediate in situ as the multifunctional core, which initiated homopolymerization of the excessive St to produce a star polymer. The kinetic studies exhibited two polymerization stages corresponding to the formation of the core with a faster propagating rate and the formation of arms by homopolymerization of St, respectively. 1H NMR spectra showed that in core formation stage random copolymer was formed. Analysis of the basic hydrolyzed products of the core by MALDI-TOF mass spectroscopy confirmed the branched structure of the core. A “6”-shaped polystyrene was also formed simultaneously, and its structure was confirmed by MALDI-TOF mass spectroscopy. Lowering the reaction temperature and using less excessive St could decrease the content of this polymer. Star polymers were characterized by 1H NMR, hydrolysis, and intrinsic viscosity.

Syntheses, in vitro antibacterial and cytotoxic activities of a series of 3-substituted succinimides

We have synthesized a series of 3-substituted succinimides and their in vitro antibacterial activities have been tested towards Gram-positive and Gram-negative bacteria from the ATCC collection. Some of them possess significant antibacterial activity against Gram-positive organisms (Staphylococcus aureus ATCC 25923 and Enterococcus faecalis ATCC 29212) but all are poorly active or inactive against Gram-negative organisms (Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853). The compounds with the lowest minimal inhibitory concentrations (esters of 3-hydroxy succinimides) are also the most cytotoxic against green monkey Vero cell line (ATCC CCL-81) and could explain that perhaps apoptosis should be implicated in eukaryotic cell cytotoxicity of succinimides.
