Potential cancer chemopreventive activity of simple isoquinolines, 1-benzylisoquinolines, and protoberberines

Seventeen simple isoquinolines, 15 1-benzylisoquinolines, and 19 protoberberines were tested for their inhibitory activities against Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol- 13-acetate (TPA) in Raji cells. Among the tested alkaloids, the inhibitory activity of all 1-benzylisoquinolines and 11 protoberberines was higher than that of beta-carotene. The 1-benzylisoquinolines 19, 21, 22, 29, and 34 and protoberberines 41, 47-49, 51, 52, and 55 showed potent inhibitory effects on EBV-EA induction (96-100% inhibition at 1 ¡Á 103 mol ratio/TPA). These alkaloids were more active than the naturally occurring alkaloids, 23, 25, 33, 53, and 54. In addition, fifteen simple isoquinolines, eighteen 1-benzylisoquinolines and eight protoberberines were evaluated with respect to their ability to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals. Nine simple isoquinolines, ten 1-benzylisoquinolines, and four protoberberines were more potent than alpha-tocopherol, and four 1-benzylisoquinolines, 20 and 28-30, exhibited potent activities (SC50 4.5-5.8 muM). Their activities were higher than the naturally occurring alkaloids, 23, 25, and 33. Therefore, some of the isoquinoline alkaloids indicating the high activity on both assays may be potentially valuable cancer chemopreventive agents. Structure-activity relationships are discussed for both tests.

17O NMR studies of boronic acids and their derivatives

The group of 155 substituted phenylboronic acids and their derivatives: esters, boroxines and benzoxaboroles, were investigated by 17O NMR spectroscopy. The influence of substituents of phenylboronic acids on the 17O chemical shift was evaluated. For the compounds with substituents at the para position, excellent correlation with the Hammett constant was obtained. For the ortho-substituted compounds use of the Charton equation gave a good correlation of results. Surprisingly, meta-substituted compounds show none of the above-mentioned correlations. A series of boronic esters of alcohols, diols and hydroxyacids were synthesized. The influence of the structure of parent hydroxy compounds on the 17O chemical shift was discussed. Selected benzoxaboroles and boroxines were also investigated, and their chemical shifts were compared with those of boronic acids. 17O NMR spectroscopy was also used to investigate the equilibria in solution. Equilibrium of the reaction of selected boronic acids with hydroxyl anions in acetonitrile was determined by 17O and 11B titration experiments. Monomer-dimer equilibria were also studied. The experimental chemical shifts were compared with the results of theoretical calculations. Very good correlations were obtained for the ortho- and para-substituents, but not for the meta ones.

Exploring the influence of the protein environment on metal-binding pharmacophores

The binding of a series of metal-binding pharmacophores (MBPs) related to the ligand 1-hydroxypyridine-2-(1H)-thione (1,2-HOPTO) in the active site of human carbonic anhydrase II (hCAII) has been investigated. The presence and/or position of a single methyl substituent drastically alters inhibitor potency and can result in coordination modes not observed in small-molecule model complexes. It is shown that this unexpected binding mode is the result of a steric clash between the methyl group and a highly ordered water network in the active site that is further stabilized by the formation of a hydrogen bond and favorable hydrophobic contacts. The affinity of MBPs is dependent on a large number of factors including donor atom identity, orientation, electrostatics, and van der Waals interactions. These results suggest that metal coordination by metalloenzyme inhibitors is a malleable interaction and that it is thus more appropriate to consider the metal-binding motif of these inhibitors as a pharmacophore rather than a “chelator”. The rational design of inhibitors targeting metalloenzymes will benefit greatly from a deeper understanding of the interplay between the variety of forces governing the binding of MBPs to active site metal ions.

Removal of the pyrrolidine substituent by dehydrogenation of 4-pyrrolidin-2-yl-3,4-dihydro- and 1,2,3,4-tetrahydroisoquinolines

Pyrrolidin-2-yl-groups located at C-4 of 3,4-dihydro- or 1,2,3,4-tetrahydroisoquinolines, respectively, are lost in the course of dehydrogenation of these isoquinoline derivatives. However, acyclically substituted isoquinolines, hydrogenated in ring B, 2-benzyl-4-(1-dimethylaminoethyl)-1,2,3,4-tetrahydroisoquinoline, e.g., show loss of the amine group only by benzylic cleavage, affording 4-ethylisoquinoline. Scope and limitation of this reaction are determined using specifically substituted isoquinolines.

Imine reductase based all-enzyme hydrogel with intrinsic cofactor regeneration for flow biocatalysis

All-enzyme hydrogels are biocatalytic materials, with which various enzymes can be immobilized in microreactors in a simple, mild, and efficient manner to be used for continuous flow processes. Here we present the construction and application of a cofactor regenerating hydrogel based on the imine reductase GF3546 from Streptomyces sp. combined with the cofactor regenerating glucose-1-dehydrogenase from Bacillus subtilis. The resulting hydrogel materials were characterized in terms of binding kinetics and viscoelastic properties. The materials were formed by rapid covalent crosslinking in less than 5 min, and they showed a typical mesh size of 67 ¡À 2 nm. The gels were applied for continuous flow biocatalysis. In a microfluidic reactor setup, the hydrogels showed excellent conversions of imines to amines for up to 40 h in continuous flow mode. Variation of flow rates led to a process where the gels showed a maximum space-time-yield of 150 g.(L.day)-1 at 100 muL/min.
