, p. 396 - 399 (2019/01/04)
A series of dipeptide aldehydes containing different N-terminal heterocycles was prepared and assayed in vitro against α-chymotrypsin to ascertain the importance of the heterocycle in maintaining a β-strand geometry while also providing a hydrogen bond do
Isomeric chiral pyrrole diamides and their efficacy in enantioselective sensing of tartrate in sol–gel medium

Pyridinium motif-based chiral pyrrole diamide clefts 1 and 2 have been designed and synthesized for chiral recognition of hydroxycarboxylates in sol–gel medium. Of the two isomeric chiral receptors, receptor 1 shows selective sensing of D-tetrabutylammonium tartrate over its mirror image isomer in CH3CN. The isomeric receptor 2 did not show any enantioselectivity in the recognition. Moreover, the receptor 1 validates prompt visual sensing of D-tartrate through gelation. The recognition properties of the receptors have been studied by fluorescence, UV–vis,1H NMR and CD spectroscopic methods.

The present invention relates to compounds of the formulae I and Ia, wherein R0 ; R1 ; R2 ; R3 ; R4; R22, Q; V, G and M have the meanings indicated in the claims. The compounds of the formulae I and Ia are valuable pharmacologically active compounds. They exhibit a strong antithrombotic effect and are suitable for the therapy and prophylaxis of cardiovascular disorders like thromboembolic diseases or restenoses. They are reversible inhibitors of the blood clotting enzymes factor Xa (FXa) and/or factor VIIa (FVIIa), and can in general be applied in conditions in which an undesired activity of factor Xa and/or factor VIIa is present or for the cure or prevention of which an inhibition of factor Xa and/or factor VIIa is intended. The invention furthermore relates to processes for the preparation of compounds of the formulae I and Ia, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.
