Polyalkoxybenzenes from plants. 5. parsley seed extract in synthesis of azapodophyllotoxins featuring strong tubulin destabilizing activity in the sea urchin embryo and cell culture assays

A series of 4-azapodophyllotoxin derivatives with modified rings B and E have been synthesized using allylpolyalkoxybenzenes from parsley seed oil. The targeted molecules were evaluated in vivo in a phenotypic sea urchin embryo assay for antimitotic and tubulin destabilizing activity. The most active compounds identified by the in vivo sea urchin embryo assay featured myristicin-derived ring E (4e, 6e, and 8e). These molecules were determined to be more potent than podophyllotoxin. Cytotoxic effects of selected molecules were further confirmed and evaluated by conventional assays with A549 and Jurkat human leukemic T-cell lines including cell growth inhibition, cell cycle arrest, cellular microtubule disruption, and induction of apoptosis. The ring B modification yielded 6-OMe substituted molecule 8e as the most active compound. Finally, in Jurkat cells, compound 8e induced caspase-dependent apoptosis mediated by the apical caspases-2 and -9 and not caspase-8, implying the involvement of the intrinsic caspase-9-dependent apoptotic pathway.

Ruthenium(II)-Catalyzed beta-Methylation of Alcohols using Methanol as C1 Source

Selective introduction of methyl branches into the carbon chains of alcohols can be achieved with low loadings of ruthenium precatalyst [RuH(CO)(BH4)(HN(C2H4PPh2)2)] (Ru-MACHO-BH) using methanol both as methylating reagent and as reaction medium. A wide range of structurally divers alcohols was beta-methylated with excellent selectivity (>99 %) in fair to high yields (up to 94 %) under standard conditions, and turnover numbers up to 18,000 could be established. The overall reaction rate of the complex catalytic network appears to be governed by interconnection of the individual subcycles through availability of the reactive intermediates. The synthetic procedure opens pathways to important structural motifs following the Green Chemistry principles.

Silver-Catalyzed Radical Transformation of Aliphatic Carboxylic Acids to Oxime Ethers

Oximes and oxime ethers are privileged building blocks and can be conveniently converted to ketones, amines, hydroxylamines, and nitriles. We describe the catalytic decarboxylation of aliphatic carboxylic acids to oxime ethers. With AgNO3 as the catalyst, valuable oxime ethers bearing various substituents could be easily obtained. The broad substrate scope, easy accessibility of aliphatic carboxylic acids, and mild reaction conditions make this strategy immediately applicable to the synthesis, late-stage functionalization, and modification of biologically active compounds. Experimental studies show the reaction undergoes a radical process.

Biocatalytic production of tetrahydroisoquinolines

The promiscuity of the enzyme norcoclaurine synthase is described. This biocatalyst yielded a diverse array of substituted tetrahydroisoquinolines by cyclizing dopamine with various acetaldehydes in a Pictet-Spengler reaction. This enzymatic reaction may provide a biocatalytic route to a range of tetrahydroisoquinoline alkaloids.

A short entry to enantiopure 2-substituted 1,4-benzodioxanes by efficient resolution methods

(R)-1,4-Benzodioxane-2-carboxilic acid (R)-1 was obtained by resolution of the racemic acid 1 with stoichiometric or nonstoichiometric (+)- dehydroabietylamine (+)-2 in high chemical yield and enantiomeric excess. (S)-1 was isolated from the mother liquors of the crystallisation of (R)-1¡¤(+)-2 and its enantiomeric excess maximised by recrystallisation procedures involving a precipitation under kinetic control or, alternatively, by conversion into the methyl ester followed by a single crystallisation. The different mechanisms of the two S enrichments is well explained by the binary phase diagrams of the acid and of the ester, which show that the former is a racemic compound, whereas the latter a conglomerate. The DSC analyses were extended to 2-hydroxymethyl- and 2-mesyloxymethyl-1,4-benzodioxane, establishing that the alcohol forms a racemic compound, while its mesyl ester a conglomerate. On the basis of these results, different resolution strategies can be designed to obtain useful homochiral 2-substituted 1,4-benzodioxanes coupling the resolution of 1 via diastereomeric salt formation with the enantiomeric enrichments by recrystallisations, preferably of its conglomerate forming derivatives.

Design, synthesis and biological evaluation of novel inosine 5?-monophosphate dehydrogenase (IMPDH) inhibitors

This study is based on our attempts to further explore the structure-activity relationship (SAR) of VX-148 (3) in an attempt to identify inosine 5?-mono-phosphate dehydrogenase (IMPDH) inhibitors superior to mycophenolic acid. A five-point pharmacophore developed using structurally diverse, known IMPDH inhibitors guided further design of novel analogs of 3. Several conventional as well as novel medicinal chemistry strategies were tried. The combined structure- and ligand-based approaches culminated in a few analogs with either retained or slightly higher potency. The compounds which retained the potency were also checked for their ability to inhibit human peripheral blood mononuclear cells proliferation. This study illuminates the stringent structural requirements and strict SAR for IMPDH II inhibition.

Synthesis and spectral properties of 4-amino-and 4-acetylamino-N- arylnaphthalimides containing electron-donating groups in the N-aryl substituent

A method for the synthesis of N-aryl-substituted 4-amino-and 4-acetylaminonaphthalimide derivatives with mono-and dialkoxy groups or a 15-crown-5 moiety in the N-aryl substituent is described. The introduction of electron-donating alkoxy groups into the benzene ring of the N-aryl fragment results in fluorescence quenching of the naphthalimide chromophore, which is most pronounced in the spectra of N-acetyl derivatives. The photophysical properties of the synthesized 4-amino-and 4-acetylaminonaphthalimides depend on the solvent polarity and its specific solvating ability due to H-bonding. The crown-containing compounds are promising fluorescent chemosensors for metal cations. ; 2009 Springer Science+Business Media, Inc.
