Process for the preparation of optically active carboxylic acids and amide intermediates

The present invention provides a process for the preparation of optically active carboxylic acids of the formula I* or II* STR1 in which X is an oxygen or sulfur atom and n is 1 or 2. The process comprises reacting a racemic carboxylic acid I or II or its derivatives with an optically active 2-amino-carboxylic acid ester to give the diastereomeric carboxylic acid amides, separating the diastereomers and, after cleavage of the amide bond, isolating the optically active carboxylic acids of the general formula I* or II*. The invention also provides certain novel optically active carboxylic acid amides and a tetrahydrothiopyran-2-carboxylic acid.

Synthesis of C-Nucleosides via Radical Coupling Reaction

Photolysis of O-acyl derivatives of N-hydroxy-2-thiopyridone, prepared from tetrahydrofuran-2-carboxylic acid, D-ribofuranosylmethanoic acid, and D-ribopyranosylmethanoic acid, gave the corresponding C-nucleoside derivatives in the presence of heteroaromatic compounds via radical pathways.The essential step in this method is a radical coupling reaction of D-ribofuranosyl radical or D-ribopyranosyl radical and some heteroaromatic bases.This is a new method for the preparation of C-nucleosides using sugar carboxylic acids.

Discovery of a potent, selective, and orally bioavailable histamine H 3 receptor antagonist SAR110068 for the treatment of sleep-wake disorders

Previous studies have shown that compound 1 displayed high affinity towards histamine H3 receptor (H3R), (human (h-H3R), Ki = 8.6 nM, rhesus monkey (rh-H3R), Ki = 1.2 nM, and rat (r-H3R), Ki = 16.5 nM), but exhibited high affinity for hERG channel. Herein, we report the discovery of a novel, potent, and highly selective H3R antagonist/inverse agonist 5a(SS) (SAR110068) with acceptable hERG channel selectivity and desirable pharmacological and pharmacokinetic properties through lead optimization sequence. The significant awakening effects of 5a(SS) on sleep-wake cycles studied by using EEG recording in rats during their light phase support its potential therapeutic utility in human sleep-wake disorders.

Influence of modification of supported palladium systems by polymers: PVP, AMPS and AcrAMPS on their catalytic properties in the reaction of transformation of biomass into fuel bio-components

Catalytic systems based on highly dispersed Pd nanoparticles deposited on SiO2 modified with PVP, AMPS and AcrAMPS were prepared and used in the hydrogenation of furfural obtained by the aqueous phase acidic hydrolysis of waste biomass (sugar beet pulp, sugar beet leaves, and brewing grain) from the food industry. Pd/PVP/SiO2 catalysts containing 50 g of Pd per 1 kg of catalyst were characterized by high activity in studied process, but lower selectivity to THFA in comparison to Pd/AMPS-SiO2 or Pd/AcrAMPS-SiO2 catalysts. The modification of SiO2 by PVP followed by the palladium catalyst loading, limited the adsorption of furfural by carbonyl group which probably leads to the improvement in THFA formation, which was confirmed by FTIR studies. The physico-chemical properties of the obtained palladium catalysts were investigated by XRD, CO chemisorption, TPR H2, TG-DTA-MS and BET techniques. The ICP-AES indicated no leaching of metal into the environment during furfural reduction, which confirms the stability of the Pd/PVP/SiO2, Pd/AMPS-SiO2 and Pd/AcrAMPS-SiO2 systems in the studied process.

Synthesis and antihypertensive activity of a series of 4-amino-6,7-dimethoxyquinazoline derivatives

A series of N2-[(acylamino)alkyl]-6,7-dimethoxy-2,4-quinazolinediamines was synthesized as potential alpha1-adrenoceptor antagonists. When administered to spontaneously hypertensive rats at 10 mg/kg po, a number of propanediamine derivatives showed good antihypertensive activity, whereas the ethanediamine derivatives, albeit being structurally more closely related to prazosin, were devoid of this property. The most active derivative, N-[3-[(4-amino-6,7-dimethoxy-2-quinazolinyl)methylamino]propyl]tetrahydro- 2-furancarboxamide hydrochloride, alfuzosin, showed high selectivity for peripheral alpha1-postjunctional adrenoceptors. At equiactive antihypertensive doses, its effect on the pressor response to postural changes in conscious dog was less marked than that shown by prazosin. In the light of these results, alfuzosin was selected for clinical evaluation.
