摘要:
The present invention relates to compounds of the formula I, wherein A, Y, Z, R20 to R22 and R50 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 LPA1 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:
Novel cyclic amino acids which are useful in preparing biologically active peptides as well as a process for the preparation of D and L enantiomers of the cyclic amino acids are described where an N-protected derivative of the racemic cyclic amino acid is treated with (-)cinchonidine and the resulting salt resolved into the desired enantiomers, as well as derivatives thereof and valuable intermediates used in the process.
摘要:
The present invention relates to novel thioxanthene and xanthene derivatives which have useful pharmacodynamic activity, such as neuroleptic activity and antiemetic activity, methods for the preparation of said derivatives, pharmaceutical compositions containing same, and a method for the treatment of psychic disorders by administering a therapeutically active amount of one of said derivatives to a living animal body, including human beings.The new compounds of the present invention correspond to the Formula I: ##STR1## wherein X is a halogen atom, an alkyl group with from one to four carbon atoms inclusive, an alkyloxy group with from one to four carbon atoms inclusive, a methylthio group, a methylsulphonyl group, a dimethylsulfamoyl group, a trifluoromethyl group or an acetyl group;Y is hydrogen, fluorine or a methyl group;Z is oxygen or sulphur;n is an integer from zero to three inclusive, andR is a cycloalkyl group with from four to six carbon atoms inclusive in the ring substituted with from one to four substituents selected from optionally esterified hydroxy- or hydroxymethyl groups, methyl groups, amino groups, acetamido groups, mesylamino groups or oxo groups, a five- or six-: membered saturated heterocyclic ring having one or two heteroatoms selected from oxygen and nitrogen atoms and being optionally substituted with an optionally esterified hydroxy group or oxo group, any esterified hydroxy group present being an ester of an aliphatic carboxylic acid having from ten to twentytwo carbon atoms inclusive, as well as their non-toxic pharmaceutically acceptable acid addition salts with the proviso that methyl is present only when one of the other named substituents is also present.
