Structure-activity relationships of cycloalkylamide derivatives as inhibitors of the soluble epoxide hydrolase

Structure-activity relationships of cycloalkylamide compounds as inhibitors of human sEH were investigated. When the left side of amide function was modified by a variety of cycloalkanes, at least a C6 like cyclohexane was necessary to yield reasonable inhibition potency on the target enzyme. In compounds with a smaller cycloalkane or with a polar group on the left side of amide function, no inhibition was observed. On the other hand, increased hydrophobicity dramatically improved inhibition potency. Especially, a tetrahydronaphthalene (20) effectively increased the potency. When a series of alkyl or aryl derivatives of cycloalkylamide were investigated to continuously optimize the right side of the amide pharmacophore, a benzyl moiety functionalized with a polar group produced highly potent inhibition. A nonsubstituted benzyl, alkyl, aryl, or biaryl structure present on the right side of the cycloalkylamide function induced a big decrease in inhibition potency. Also, the resulting potent cycloalkylamide (32) showed reasonable physical properties.

Novel PARP-1 inhibitors based on a 2-propanoyl-3H-quinazolin-4-one scaffold

Poly(ADP-ribose)polymerase-I (PARP-1) enzyme is involved in maintaining DNA integrity and programmed cell death. A virtual screening of commercial libraries led to the identification of five novel scaffolds with inhibitory profile in the low nanomolar range. A hit-to-lead optimization led to the identification of a group of new potent PARP-1 inhibitors, acyl- piperazinylamides of 3-(4-oxo-3,4-dihydro-quinazolin-2-yl)-propionic acid. Molecular modeling studies highlighted the preponderant role of the propanoyl side chain.

On the role of modifier structure in the palladium-catalyzed enantioselective hydrogenation of furan-2-carboxylic acid

Enantioselective hydrogenation of the aromatic ring of furancarboxylic acids is an important new application of cinchona-modified palladium as there is no synthetically useful method yet available for this transformation. Here we report a mechanistic investigation of the hydrogenation of furan-2-carboxylic acid. The 5 wt.% Pd/Al2O3 catalyst was chirally modified by cinchonidine (CD) derivatives, (R)-1-(1-naphthyl)ethylamine derivatives, and (R)-1-(1-naphthyl)-ethanol. Variation of the structure of the modifiers revealed that the major requirement an efficient chiral modifier has to fulfill is the presence of a basic N and an OH function. The relative position of the two functional groups and the acidity (proton donor ability) of the OH group are not critical as indicated by the similar efficiency of 1,2- and 1,3-amino alcohols and amino phenols. The enantioselection is attributed to the formation of a cyclic, 2:1 acid:modifier complex that adsorbs close to parallel to the Pd surface via pi-bonding of the aromatic rings of substrate and modifier. The model can interpret also the effect of a strong acid additive. The poor performance of amine type modifiers is attributed to the formation of too flexible, acyclic structures.

Direct Ruthenium-Catalyzed Hydrogenation of Carboxylic Acids to Alcohols

The “green” reduction of carboxylic acids to alcohols is a challenging task in organic chemistry. Herein, we describe a general protocol for generation of alcohols by catalytic hydrogenation of carboxylic acids. Key to success is the use of a combination of Ru(acac)3, triphos and Lewis acids. The novel method showed broad substrate tolerance and a variety of aliphatic carboxylic acids including biomass-derived compounds can be smoothly reduced.

Catalytic direct amidations in: Tert -butyl acetate using B(OCH2CF3)3

Catalytic direct amidation reactions have been the focus of considerable recent research effort, due to the widespread use of amide formation processes in pharmaceutical synthesis. However, the vast majority of catalytic amidations are performed in non-polar solvents (aromatic hydrocarbons, ethers) which are typically undesirable from a sustainability perspective, and are often poor at solubilising polar carboxylic acid and amine substrates. As a consequence, most catalytic amidation protocols are unsuccessful when applied to polar and/or functionalised substrates of the kind commonly used in medicinal chemistry. In this paper we report a practical and useful catalytic direct amidation reaction using tert-butyl acetate as the reaction solvent. The use of an ester solvent offers improvements in terms of safety and sustainability, but also leads to an improved reaction scope with regard to polar substrates and less nucleophilic anilines, both of which are important components of amides used in medicinal chemistry. An amidation reaction was scaled up to 100 mmol and proceeded with excellent yield and efficiency, with a measured process mass intensity of 8.
