A series of unsubstituted and subsituted succinimido, maleimido, and glutarimidoethyl derivatives of eltoprazine (3) was synthesized and tested for affinity for the 5-HT1A receptor in rat brain homogenates.The unsubstituted compounds have a moderate affinity for the receptor, while the affinity considerably increases by substitution at or enlargement of these cyclic ring systems.A good correlation was found between the inhibition constant Ki (expressed as pKi) and the lipophilicity (clogP).No correlation was observed between the pKi or pKi+ (local inhibition constant) and the basicity of the N4-nitrogen atom.

Ruthenium nanoparticles supported on titania are over three times more active than conventional ruthenium on carbon for the hydrogenation of lactic acid. This superior catalytic activity can be due to a combined action of small ruthenium nanoparticles and the titania support.

Catalysts and methods for the double carbonylation of epoxides are disclosed. Each epoxide molecule reacts with two molecules of carbon monoxide to produce a succinic anhydride. The reaction is facilitated by catalysts combining a Lewis acidic species with a transition metal carbonyl complex. The double carbonylation is achieved in single process by using reaction conditions under which both carbonylation reactions occur without the necessity of isolating or purifying the product of the first carbonylation.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4100-80-5

Using molecular modeling and rationally designed structural modifications, the multi-target structure?activity relationship for a series of ranitidine analogs has been investigated. Incorporation of a variety of isosteric groups indicated that appropriate aromatic moieties provide optimal interactions with the hydrophobic and pi?pi interactions with the peripheral anionic site of the AChE active site. The SAR of a series of cyclic imides demonstrated that AChE inhibition is increased by additional aromatic rings, where 1,8-naphthalimide derivatives were the most potent analogs and other key determinants were revealed. In addition to improving AChE activity and chemical stability, structural modifications allowed determination of binding affinities and selectivities for M1?M4 receptors and butyrylcholinesterase (BuChE). These results as a whole indicate that the 4-nitropyridazine moiety of the JWS-USC-75IX parent ranitidine compound (JWS) can be replaced with other chemotypes while retaining effective AChE inhibition. These studies allowed investigation into multitargeted binding to key receptors and warrant further investigation into 1,8-naphthalimide ranitidine derivatives for the treatment of Alzheimer’s disease.

Sirtuins are NAD+-dependent deacetylases acting as sensors in metabolic pathways and stress response. In mammals there are seven isoforms. The mitochondrial sirtuin 5 is a weak deacetylase but a very efficient demalonylase and desuccinylase; however, its substrate acyl specificity has not been systematically analyzed. Herein, we investigated a carbamoyl phosphate synthetase 1 derived peptide substrate and modified the lysine side chain systematically to determine the acyl specificity of Sirt5. From that point we designed six potent peptide-based inhibitors that interact with the NAD+ binding pocket. To characterize the interaction details causing the different substrate and inhibition properties we report several X-ray crystal structures of Sirt5 complexed with these peptides. Our results reveal the Sirt5 acyl selectivity and its molecular basis and enable the design of inhibitors for Sirt5. Small changes make the difference: Systematic investigation of the acyl substrate specificity of sitruin 5 uncovers its unique preference for succinyl and glutaryl residues. Depending on the chemical nature of introduced modifications, either high-affinity substrates or sirtuin 5 specific inhibitors could be obtained.

Reactions of five-membered cyclic dicarboxylic anhydrides, such as phthalic anhydride and succinic anhydride, with RuH2(PPh3)4 give ruthenium complexes with 2-formyl benzoate and 3-formyl propionate , via the C-O bond cleavage of the anhydrides.Similar reactions of methylsuccinic anhydride or ethylsuccinic anhydride with RuH2(PPh3)4 afford mixtures of the isomer (R=CH3 or C2H5), in ca. 3 to 1 molar ratio in each reaction.Complexes with 2-acyl benzoate or 3-acyl propionate ligands formulated as or (R’=CH3, C6H5) are prepared from the reactions of corresponding 2-acyl benzoic or 3-acyl propionic acids with RuH2(PPh3)4.Upon contact with hydrogen at elevated pressure, or with hydrogen chloride or carbon monoxide at atmospheric pressure, these complexes release the corresponding gamma-lactones, which are formed through the reduction of formyl or acyl groups in the carboxylate ligands followed by intramolecular condensations.Hydrogenation of 3-acyl propionic acids using ruthenium(II) complexes as catalyst gives gamma-substituted gamma-lactones in high yields.

Metal containing cyclic ester complexes, L<*> (L=1,2-bis(diphenylphosphino)ethane (dpe) or 2,2′-bipyridine (bpy); R1, R2=H or CH3) and Ln<*> )L=tricyclohexylphosphine (PCy3) or dpe; n=1 or 2), have been prepared by oxidative addition of cyclic carboxylic anhydrides to zero-valent metal complexes.These complexes have been characterized by elemental analysis and spectroscopies (IR as well as 1H-, 13C<1H>-, and 31P<1H>-NMR) and chemical rectivities.Rate of the oxidative addition of succinic anhydride to Ni(bpy)(cod) (cod=1,5-cyclooctadiene) is expressed by a second order rate equation, R=k, and temperature dependence of k gives the activation energy of 68 kJ mol-1.The reaction of methylsuccinic anhydride with Ni(cod)2 in the presence of tertiary phosphine or bpy affords two isomers, Ln<*> and Ln<*>, corresponding to two modes of C-O bond cleavage in methylsuccininc anhydride promoted by Ni; dependence of the ratio between the two isomers on the kind of ligand added and reaction conditions has been examined.

The use of electrolyte additives is an important method to improve lithium-ion cell lifetime and performance without significantly affecting costs. This work evaluates two organic anhydrides, glutaric anhydride (GA) and citraconic anhydride (CA), as additives in Li(Ni0.6Mn0.2Co0.2)O2 (NMC622)/graphite and Li(Ni0.5Mn0.3Co0.2)O2 (NMC532)/graphite pouch cells, using ultrahigh precision coulometry and higherature storage. The additives were tested singly and in binary blends. GA-based additive blends give high coulombic efficiencies (CEs) and good storage performance. However, GA leads to substantial impedance during formation. Most notably, GA is extremely effective at suppressing gas during cell formation and storage. Whereas CA-containing blends yield good CEs, they show rapid voltage drop during storage. Both additives may provide specific benefits for target applications. Long-term cycling data indicates that GA is a negative electrode SEI-forming additive that is useful for capacity retention and limiting cell impedance growth when used as a binary blend with vinylene carbonate or lithium difluorophosphate. These results are also intended to facilitate comparison between chemically related additives in order to better understand the underlying chemistry behind their function in lithium-ion cells.
