SOLIFENACIN SALTS

The invention concerns fumarate salts of solifenacin, as well as pharmaceutical compositions comprising fumarate salts of solifenacin. The invention furthermore concerns a process for preparing solifenacin and salts thereof. The fumarate salt provides improved properties over the known solifenacin salts, especially in terms of its stability. The novel process for its preparation is furthermore improved over known processes for preparing solifenacin in that it provides a higher yield and recovers a greater amount of starting material.

Electron-donating para-methoxy converts a benzamide-isoquinoline derivative into a highly Sigma-2 receptor selective ligand

The sigma-2 (sigma2) receptor has been suggested to be a promising target for pharmacological interventions to curb tumor progression. Development of sigma2-specific ligands, however, has been hindered by lack of understanding of molecular determinants that underlie selective ligand-sigma2 interactions. Here we have explored effects of electron donating and withdrawing groups on ligand selectivity for the sigma2 versus sigma1 receptor using new benzamide-isoquinoline derivatives. The electron-donating methoxy group increased but the electron-withdrawing nitro group decreased sigma2 affinity. In particular, an extra methoxy added to the para-position (5e) of the benzamide phenyl ring of 5f dramatically improved (631 fold) the sigma2 selectivity relative to the sigma1 receptor. This para-position provided a sensitive site for effective manipulation of the sigma receptor subtype selectivity using either the methoxy or nitro substituent. Our study provides a useful guide for further improving the sigma2-over-sigma1 selectivity of new ligands.

Antidepressant-like effect of 1,2,3,4-tetrahydroisoquinoline and its methyl derivative in animal models of depression

Background Most of the currently used antidepressant drugs are monoamine-based compounds, acting by the inhibition of re-uptake or metabolism of noradrenaline (NA) and/or serotonin (5-HT), because these neurotransmitters play a key role in the pathophysiology of depression. The aim of this study was to investigate the potential antidepressant-like activity of an endogenous amine, 1,2,3,4-tetrahydroisoquinoline (TIQ) and its close derivative, 1-methyl-1,2,3,4-tetrahydroisoquinoline (1MeTIQ). Methods The experiments were carried out on male C57BL6J mice. The antidepressant-like activity of TIQs was evaluated in the behavioral tests: the forced swim test (FST) and tail suspension test (TST) and neurochemical analysis. TIQ and 1MeTIQ were administrated in three differences doses of 10, 25 or 50?mg/kg. Imipramine (IMI; 15 or 30?mg/kg) was used as a reference drug. In the neurochemical ex vivo study, the levels of NA, 5-HT and their metabolites, the rate of monoamine metabolism and their neuronal activity in different mouse brain structures were determined by HPLC with electrochemical detection. Results The results of this study have demonstrated that TIQ and 1MeTIQ produced antidepressant-like effect in the FST and TST because they significantly decreased the immobility time comparably to IMI. Biochemical data have demonstrated that administration of TIQs led to the activation of NA and 5-HT systems. Conclusions The results reported in this paper indicate that TIQ and 1MeTIQ possess a distinct antidepressant activity. In the light of these findings, we suggest that both tested compounds may be effective for the depression therapy in a clinical setting with better tolerance of side effects.

Palladium in Photocatalysis

The concept of photoredox/transition-metal dual catalysis has been validated as a powerful platform for the construction of carbon-carbon and carbon-heteroatom bonds, and it illustrates the power of rational design in catalysis and the strategic use of mechanistic knowledge and manipulation for the development of novel synthetic methods. This chapter describes recent progress in the combination of visible-light photoredox catalysis with palladium catalysis, highlighting this as a valuable synthetic tool in accessing complex molecules in a rapid and modular fashion.

N-Methylation of amine and nitro compounds with CO2/H2 catalyzed by Pd/CuZrOx under mild reaction conditions

An active Pd/ZrCuOx catalyst was prepared for the reductive amination of CO2. The N-methylation of amines and nitro compounds with CO2/H2 can be realized with up to 97% yield under relatively mild reaction conditions. N-Formylation becomes the main reaction if the reaction was performed under milder conditions or using Pd/ZnZrOx as the catalyst.

3-(3,4-dihydroisoquinolin-2(1 H)-ylsulfonyl)benzoic acids: Highly potent and selective inhibitors of the type 5 17-beta-hydroxysteroid dehydrogenase AKR1C3

A high-throughput screen identified 3-(3,4-dihydroisoquinolin-2(1H)- ylsulfonyl)benzoic acid as a novel, highly potent (low nM), and isoform-selective (1500-fold) inhibitor of aldo-keto reductase AKR1C3: a target of interest in both breast and prostate cancer. Crystal structure studies showed that the carboxylate group occupies the oxyanion hole in the enzyme, while the sulfonamide provides the correct twist to allow the dihydroisoquinoline to bind in an adjacent hydrophobic pocket. SAR studies around this lead showed that the positioning of the carboxylate was critical, although it could be substituted by acid isosteres and amides. Small substituents on the dihydroisoquinoline gave improvements in potency. A set of “reverse sulfonamides” showed a 12-fold preference for the R stereoisomer. The compounds showed good cellular potency, as measured by inhibition of AKR1C3 metabolism of a known dinitrobenzamide substrate, with a broad rank order between enzymic and cellular activity, but amide analogues were more effective than predicted by the cellular assay.

C-1 alkynylation of N-methyltetrahydroisoquinolines through CDC: A direct access to phenethylisoquinoline alkaloids

Direct cross-coupling between N-methyltetrahydroisoquinolines and alkynes using CuI-DEAD is presented. It affords the regioselective C-1-alkynylated products in good yield. This regio-selectivity is in contrast to the results reported earlier in the reaction of N,N-dimethylbenzyl amine where the N-methyl alkynylated product was formed exclusively or predominantly. The C-1-substituted propargylic isoquinolines were easily reduced to phenethylisoquinolines with Pd/C. This reaction sequence provides a short route to synthesize methopholine, homolaudanosine and other phenethylisoquinoline alkaloids. Georg Thieme Verlag Stuttgart ¡¤ New York.
