• Cyclopropane-1,2-dicarboxylic acids as new tools for the biophysical investigation of<i>O</i>-acetylserine sulfhydrylases by fluorimetric methods and saturation transfer difference (STD) NMR

  Cysteine is a building block for many biomolecules that are crucial for living organisms. O-Acetylserine sulfhydrylase (OASS), present in bacteria and plants but absent in mammals, catalyzes the last step of cysteine biosynthesis. This enzyme has been deeply investigated because, beside the biosynthesis of cysteine, it exerts a series of "moonlighting" activities in bacteria. We have previously reported a series of molecules capable of inhibiting Salmonella typhimurium (S. typhymurium) OASS isoforms at nanomolar concentrations, using a combination of computational and spectroscopic approaches. The cyclopropane-1,2-dicarboxylic acids presented herein provide further insights into the binding mode of small molecules to OASS enzymes. Saturation transfer difference NMR (STD-NMR) was used to characterize the molecule/ enzyme interactions for both OASS-A and B. Most of the compounds induce a several fold increase in fluorescence emission of the pyridoxal 5'-phosphate (PLP) coenzyme upon binding to either OASS-A or OASS-B, making these compounds excellent tools for the development of competition-binding experiments.
• Conformationally restrained carbamoylcholine homologues. Synthesis, pharmacology at neuronal nicotinic acetylcholine receptors and biostructural considerations

  Exploration of small selective ligands for the nicotinic acetylcholine receptors (nAChRs) based on acetylcholine (ACh) has led to the development of potent agonists with clear preference for the 042 nAChR, the most prevalent nAChR subtype in the central nervous system. In this work we present the continuation of these efforts aimed at increasing this subtype selectivity by introduction of conformational restriction in the carbamoylcholine homologue, 3-(dimethylaminobutyl) dimethylcarbamate (DMABC). Our results highlight the importance of the N-carbamoyl substitution in alpha(4)beta(2)-subtype selectivity. Moreover, we have confirmed the non-linear conformation of DMABC bound to nAChRs suggested by recent crystal structures of the compound in complex with the Lymnaea stagnalis ACh binding protein.

• Cyclopropane derivatives as potential human serine racemase inhibitors: unveiling novel insights into a difficult target

  D-Serine is the co-agonist of NMDA receptors and binds to the so-called glycine site. D-Serine is synthesized by human serine racemase (SR). Over activation of NMDA receptors is involved in many neurodegenerative diseases and, therefore, the inhibition of SR might represent a novel strategy for the treatment of these pathologies. SR is a very difficult target, with only few compounds so far identified exhibiting weak inhibitory activity. This study was aimed at the identification of novel SR inhibitor by mimicking malonic acid, the best-known SR inhibitor, with a cyclopropane scaffold. We developed, synthesized, and tested a series of cyclopropane dicarboxylic acid derivatives, complementing the synthetic effort with molecular docking. We identified few compounds that bind SR in high micromolar range with a lack of significant correlation between experimental and predicted binding affinities. The thorough analysis of the results can be exploited for the development of more potent SR inhibitors.

• Substituent Effect in the Ionization of<i>cis</i>-2-Substituted 1-Cyclopropanecarboxylic Acids
  作者：Yoshiaki Kusuyama

  Ten cis-2-substituted 1-cyclopropanecarboxylic acids (substituents: H, CH3, C6H5, CH3O, C2H5O, Cl, Br, CH3CO, CH3OCO, and C2H5OCO) were prepared, and their pKa values were determined in water at 25 °C, along with those of the trans-2-chloro and 2-methoxy derivatives. The pKa values for cis isomers are somewhat larger than those for the corresponding trans isomers, except for the chloro and bromo derivatives. The substituent effects obtained were in the usual order in the sense of the electronic effects, except for the phenyl group, which produced a decrease in acidity relative to the unsubstituted acid. It was shown that the carbon-13 chemical shifts for the methylene carbon of the ethyl group in the ethyl cis-2-substituted 1-cyclopropanecarboxylate obtained in deuteriochloroform gave a reasonable linear relation with the pKa(cis) values.
