A series of 1-sulfonylaminocyclopropanecarboxylates was synthesized as ADAMTS-5 (Aggrecanase-2) inhibitors. After an intensive investigation of the central cyclopropane core including its absolute stereochemistry and substituents, we found compound 22 with an Agg-2 IC50=7.4 nM, the most potent ADAMTS-5 inhibitor reported

The effects of the hypoglycemic agent, cyclopropane carboxylate, on the metabolism of various substrates that enter the mitochondrion via the mitochondrial monocarboxylate transporter were investigated in perfused rat livers. Metabolism of pyruvate, branched-chain alpha-keto acids, acetoacetate and, to a lesser
The compound (1R,2S/1S,2R)-2-[4-hydroxy-4-phenylpiperidin-1-yl)methyl]-1-(4-methylphenyl) cyclopropanecarboxylate [(+/-)-PPCC] is a ligand with high affinity for sigma (sigma) sites of which the selectivity towards several other receptor systems has been demonstrated. Given the existence of a relationship between the sigma system and the kappa

Conjugation with carnitine is a major metabolic pathway for cyclopropanecarboxylic acid (CPCA). The CPCA-carnitine is cleaved enzymatically (carnitine acetyltransferase) more slowly in vitro than are acetyl- and propionylcarnitines, but also slightly more extensively. When given orally to a rat, CPCA-carnitine

Highly effective asymmetric hydrogenation of protected ethyl 1-(2-aminoaceto)cyclopropane carboxylates in the presence of [RuCl(benzene)(S)-SunPhos]Cl was realized, and high enantioselectivities (up to 98.7% ee) were obtained. This asymmetric hydrogenation provides a key intermediate for the enantioselective synthesis of (S)-7-amino-5-azaspiro[2.4]heptane moiety of
