receptor antagonists recently proposed, we applied comparative molecular field analysis (CoMFA) to obtain a three-dimensional quantitative structure-activity relationship for pyridine derivatives, having good predictability (r2pred = 0.873) for compounds in the test set. A rhodopsin-based model of the human A3 receptor was built, and the pyridine reference ligand 2,3,4, 5-tetraethyl-6-phenyl-pyridine-3-th

A compound represented by the formula wherein R1 and R2 are the same or different and each is an optionally substituted hydrocarbon group or an optionally substituted hydroxy group; R3 is an optionally substituted aromatic group; R4 is an optionally substituted amino group; L is a divalent chain hydrocarbon group; Q is a bond or a divalent chain hydrocarbon group; and X is a hydrogen atom, a cyano group, a nitro group, an acyl group, a substituted hydroxy group, an optionally substituted thiol group, an optionally substituted amino group or an optionally substituted cyclic group; provided that when X is an ethoxycarbonyl group, then Q is a divalent chain hydrocarbon group. The compound has a peptidase inhibitory action, is useful as an agent for the prophylaxis or treatment of diabetes and the like, and is superior in efficacy, duration of action, specificity, lower toxicity and the like.

E-isomeric ß-(hetero) aromatically substituted acylaminoacrylates are of great economic interest since with them, by means of hydration, precursors of appropriately substituted (ß-amino acids can be prepared and, by doing so, lead to higher enantio-selectivities than the corresponding Z-isomers. The invention describes novel E-isomeric R-aromatically or ß-heteroaromatically substituted ß-acylaminoacrylates of the general formula (I): in which R represents hydrogen or a substituted or unsubstituted alkyl or aromatic or heteroaromatic residue, and R' represents a substituted or unsubstituted aromatic or heteroaromatic residue, R' represents H, a substituted or unsubstituted alkyl or aromatic or heteroaromatic residue, and R'' represents H, a substituted or unsubstituted alkyl, acyl, aromatic or heteroaromatic residue. According to the invention, the compounds according to the general formula (I) are prepared by acylation at temperatures below the boiling point of the reaction mixture.
