An investigation has been conducted into the staged synthesis of 2-methylimidazole from ethylenediamine and acetic acid in the presence of a bifunctional aluminoplatinum catalyst.It has been shown that the formation stage of 2-methylimidazoline occurs more quickly on gamma-Al2O3 than its dehydrogenation on the Pt centers.From a comparison of the processes of dehydrogenation of 2-methylimidazoline in the molten phase and in aqueous solution it follows that the water eliminated in the imidazoline formation stage could cause the decrease in activity during the dehydrogenation on the Pt centers.The structures of the secondary and intermediate products have been established for each stage of the process and their formation routes are discussed. Keywords: aluminoplatinum catalysts, bifunctional catalysis, alkylimidazoles, 2-methylimidazole.

The non-P1 and non-P2 muscle relaxant effect of ATP in rabbit thoracic aorta has recently been attributed to a putative P3 purinoceptor, which is activated by either adenosine or ATP. Since the physiological roles of this putative P3 purinoceptor and of a new [3H]-5?-N-ethylcarboxamidoadenosine (NECA)-binding protein from rat brain membranes called P3 purinoceptor-like protein (P3LP), due to its ligand specificity, have not been fully elucidated, we needed a specific ligand to obtain further information about the receptor. We examined the structure-activity relationship (SAR) of various 5?-N-substituted-carboxamidoadenosine derivatives toward P3LP and discovered a hydrophobic binding region near the 5?-N-substituted-carboxamide group. From the linear alkyl N-substituted derivatives, the N-n-pentyl derivative 10 was found to be the most potent ligand with a Ki value of 12 nM. In the series of the N-cycloalkyl derivatives, the N-cyclohexyl derivative 27 was the strongest ligand with a Ki value of 18 nM. On the other hand, the N-substituents having branched alkyl side chains and bulky cycloalkyl groups did not show any potent affinities for P3LP. Therefore, the hydrophobic pocket accommodates approximately a 10-carbon-atom-long linear alkyl side chain, while a considerably stronger hydrophobic binding region of about a 5-carbon-atom-long depth exists near the nitrogen atom of the amide group. This pocket also allows substitution with bulky hydrophobic groups since the 5?-N-cycloalkyl derivatives have high affinities. We also examined the receptor selectivity for the selected nucleosides 10 and 27 with 1 [9-(6,7-dideoxy-beta-D-allohept-5-ynofuranosyl)adenine, HAK2701] and NECA versus P1 purinoceptor subtypes, such as adenosine A1, A2A, A2B, and A3 receptors, and found that 27 is the most selective ligand for P3LP.

Second-order rate constants (kn) for the aminolysis of some phenyl acetates with poly(ethylenimine) (PEI) were obtained in a pH range 4.36-11.20 at 25 C in 1 M KC1. Linear Bronsted-type plots (log kn vs pKN of PEI) were found for less reactive esters 2-nitrophenyl acetate, 4-acetoxy-3-chlorobenzoic acid, and 4-acetoxybenzenesulfonate with slopes of 0.92, 0.99, and 0.82, respectively. Curved plots were obtained for 3-acetoxy-2,6-dinitrobenzoic acid and 4-acetoxy-3-nitrobenzene-sulfonate, which are consistent with a stepwise reaction. The most likely mechanism involves the existence of a tetrahedral intermediate (T±) and a change in the rate-determining step from its breakdown to its formation when the basicity of the polyamine increases. A semiempirical equation was used to calculate the values of limiting slopes of the plots (0.9 and 0.1 for both esters) and pKN at the center of the curvature of the plots (p-KN = 7.94 and 9.02, respectively). The values of pKN are lower than those estimated for the aminolysis of the same esters with simple monomeric amines (pKn > 11) because of a better leaving ability of the aryl oxide ion from the tetrahedral intermediate when amino groups of PEI instead of simple amines are involved. Estimation of the pK’s of the reactive intermediates and of the microscopic rate constants for the proton transfer from T± to PEI or from PEIH+ to T± indicates that either base or acid catalysis is unimportant in the aminolysis of these esters by PEI.

A series of novel sulfonamides containing a single difluoromethylene- phosphonate group were discovered to be potent inhibitors of protein tyrosine phosphatase 1B. Structure-activity relationships around the scaffold were investigated, leading to the identification of compounds with IC50 or Ki values in the low nanomolar range. These sulfonamide-based inhibitors exhibit 100 and 30 times higher inhibitory activity than the corresponding tertiary amines and carboxamides, respectively.

Reversible and selective monoamine oxidase-A inhibitors (RIMA’s) like moclobemide (Aurorix<*>) have rehabilitated the use of MAO inhibitors as drugs of choice in depression.Starting from the structure of moclobemide, we tried to identify novel types of MAO inhibitors by bioisosteric replacement of the amide group. 2-Aminomethyl-5-phenylpyrroles retained some in vitro activity and served as a starting point for the construction of restricted rotation analogues. 3,4-Dihydro-6-phenylpyrrolo<1,2-a>pyrazines were the most interesting members of a family of 6-, 7-, and 8-phenyl-substituted pyrrolo<1,2-a>pyrazines and were subsequently optimized.A ‘lipophilic linker’ between phenyl and pyrrole ring proved exceedingly useful to improve affinity and led to the benzolpyrazino<1,2-a>indole ring system.Synthetic procedures starting from substituted 1-tetralones allowed the synthesis of substituted derivatives of this ring system.Once the optimal substitution pattern had been identified, facile synthesis of derivatives was achieved from aromatic triflates by Stille or Suzuki coupling.In this series selective and reversible monoamine oxidase-A inhibitors as well as mixed MAO-A and B inhibitors were identified.Affinity of these compounds for MAO was in the nanomolar or even sub-nanomolar range (for monoamine oxidase-A).In conclusion, benzopyrazino<1,2-a>indoles have been identified as a new class of reversible and highly potent monoamine oxidase inhibitors.

(Figure Presented) This paper describes the construction of a combinatorial artificial receptor array (CARA) and the application of the array to differentiation of proteins based on their binding patterns. Microarrays displaying 5035 unique binding environments were prepared using a library of 19 small molecule building blocks. Each building block was equipped with a carboxylic acid handle, allowing mixtures of the building blocks to be spotted onto the surface of an amine functionalized glass slide for covalent immobilization as subunits of the binding environments. This strategy employs the microarray surface as the receptor synthesis platform, which allows for flexibility in array preparation and agility in application. An advantage of the CARA strategy is the enormous flexibility it enables in the construction of alternate microarray configurations, which facilitates rapid access to the breadth and depth of binding space. Four fluorescently labeled proteins, ubiquitin, myoglobin, alpha-1-acid glycoprotein and lysozyme, were incubated with the arrays to demonstrate the reproducibility of binding and the level of differentiation that can be achieved. The binding environments are stable, scalable, and adaptable to other formats.

Novel Hits in the Correction of deltaf508-Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) Protein: Synthesis, Pharmacological, and ADME Evaluation of Tetrahydropyrido[4,3-d]pyrimidines for the Potential Treatment of Cystic Fibrosis

Cystic fibrosis (CF) is a lethal genetic disease caused by mutations of the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) with a prevalence of the deltaF508 mutation. Whereas the detailed mechanisms underlying disease have yet to be fully elucidated, recent breakthroughs in clinical trials have demonstrated that CFTR dysfunction can be corrected by drug-like molecules. On the basis of this success, a screening campaign was carried out, seeking new drug-like compounds able to rescue deltaF508-CFTR that led to the discovery of a novel series of correctors based on a tetrahydropyrido[4,3-d]pyrimidine core. These molecules proved to be soluble, cell-permeable, and active in a disease relevant functional-assay. The series was then further optimized with emphasis on biological data from multiple cell systems while keeping physicochemical properties under strict control. The pharmacological and ADME profile of this corrector series hold promise for the development of more efficacious compounds to be explored for therapeutic use in CF.
