The present invention relates to compounds of the formula (I) wherein A, Y, Z, R 20 to R 22 and R 50 have the meanings indicated in the claims, which are valuable pharmaceutical active compounds. Specifically, they are inhibitors of the endothelial differentiation gene receptor 2 (Edg-2, EDG2), which is activated by lysophosphatidic acid (LPA) and is also termed as LPA 1 receptor, and are useful for the treatment of diseases such as atherosclerosis, myocardial infarction and heart failure, for example. The invention furthermore relates to processes for the preparation of the compounds of the formula (I), their use and pharmaceutical compositions comprising them.
摘要:
Provided is a process for preparing 3,4-substituted thiophenes by reacting a thiophenedicarboxylic acid derivative in an aprotic polar solvent at the presence of a catalyst mixture of 1,8-Diazabicyclo[5,4,0]undec-7-ene and a copper salt. The 3,4-substituted thiophenes according to the present invention is prepared to have high purity and a high yield and has a benefit that a reaction is efficiently generated at 100 to 180?, which is a lower temperature than that of the related art, by using a catalyst containing 1,8-Diazabicyclo[5,4,0]undec-7-ene (DBU) and a copper salt.

The class compounds of the present invention may be represented by Formula (I), wherein X may be O, S, or N. R 1 and R 2 are independently either H, C 1 -C 20 alkyl, cycloalkyl, alkenyl, aryl, arylalkyl, or alkylaryl. R 3 and R 4 are independently either H, an aryl group, a heteroaryl group, and a heterocyclic ring group having 4 to 6 carbon atoms, wherein the aryl, heteroaryl, and heterocyclic moieties are optionally substituted with one or more of a first substitution group defined herein. In a further embodiment, R 3 and R 4 along with the atoms and bonds to which they are attached, form an optionally substituted 5-7 membered ring having at least one nitrogen atom within the ring structure.

摘要:
The present invention provides compounds and methods for modulation of the quorum sensing of bacteria. In an embodiment, the compounds of the present invention are able to act as replacements for naturally occurring bacterial quorum sensing ligands in a ligand-protein binding system; that is, they imitate the effect of natural ligands and produce an agonistic effect. In another embodiment, the compounds of the present invention are able to act in a manner which disturbs or inhibits the naturally occurring ligand-protein binding system in quorum sensing bacteria; that is, they produce an antagonistic effect. The compounds of the present invention comprise N-acylated-homoserine lactones (AHLs) comprised of a wide range of acyl groups.

摘要:
Methods for synthesizing Salacinol, its stereoisomers, and analogues, homologues and other derivatives thereof potentially useful as glycosidase inhibitors are described. In some embodiments the compounds of the invention may have the general formula (I) or (II). The synthetic schemes may comprise reacting a cyclic sulfate with a 5-membered ring sugar containing a heteroatom (X). The heteroatom preferably comprises sulfur, selenium, or nitrogen. The cyclic sulfate and ring sugar reagents may be readily prepared from carbohydrate precursors, such as D-glucose, L-glucose, D-xylose and L-xylose. The target compounds are prepared by opening of the cyclic sulfates by nucleophilic attack of the heteroatoms on the 5-membered ring sugars. The resulting heterocyclic compounds have a stable, inner salt structure comprising a heteroatom cation and a sulfate anion. The synthetic schemes yield various stereoisomers of the target compounds in moderate to good yields with limited side-reactions. Chain-extended analogues of Salacinol are also described.
