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

Wang, Fan,Xu, Xiao-Ying,Wang, Fei-Ying,Peng, Lin,Zhang, Yong,Wang, Liang-Liang,Wang, Li-Xin
, p. 741 - 744 (2016/03/25)
An effective and improved process for the preparation of cis-cyclopro panediamine dihydrochloride was developed in a 100 g scale. The key step in the process is the preparation of ciscyclopropane-1, 2-dicarboxylic acid from a mixture of cis- and transisomers by the formation of cyclic acidic anhydride. The whole process and all of the procedures are economical, industrially reliable and easily scaled up.
Enantioselective bacterial hydrolysis of amido esters and diamides derived from (±)-trans-cyclopropane-1,2-dicarboxylic acid
Hugentobler, Katharina G.,Rebolledo, Francisca
, p. 615 - 623 (2014/01/06)
Different optically active amido esters, mixed acid esters, amido acids, and diamides derived from trans-cyclopropane-1,2-dicarboxylic acid were prepared from the commercially available diethyl (±)-trans-cyclopropane-1,2- dicarboxylate. The key step was the Rhodococcus rhodochrous IFO 15564 catalyzed hydrolysis of the corresponding racemic amide. The amidase present in this microorganism showed moderate to high enantioselectivity towards these substrates. In addition a simple and efficient Curtius rearrangement of some of the enzymatically prepared cyclopropanecarboxylic acids allowed us to obtain optically active β-aminocyclopropanecarboxylic acid derivatives with high yields and enantiomeric excesses.

body text, p. 1930 - 1936 (2011/07/07)
A new method for the synthesis of (1R,4S,5S)-4-hydroxymethyl-3- oxabicyclo[3.1.0]hexan-2-one, the cyclopropane analog of (S)-5-hydroxypent-2-en- 4-olide, has been suggested based on oxidation of (1S,2S,4R,6R)-7,9- dioxatricyclo[4.2.1.02,4]nonan-5-one. Oxidation of cyclobutanones, spirojoined with the fragments of 6,8-dioxabicyclo[3.2.1]oct-2-ene, 6,8-dioxabicyclo[3.2.1]octane (at position 4), or 7,9-dioxatricyclo[4.2.1.0 2,4]nonane (at position 5), upon the action of m-chloroperoxybenzoic acid or the KMnO4-H2SO4-H2O system leads to the corresponding spirojoined butanolides in 73-85% yields. The same cyclobutanones easily undergo the four-membered ring opening upon the action of dilute H2SO4 at 50-90 °C to form 6,8-dioxabicyclo[3.2. 1]octane-4-or 7,9-dioxatricyclo[4.2.1.02,4]nonane-5-propionic acid.
