The invention is concerned with novel mandelic acid derivatives of formula (I)
wherein R1 to R10, X and Y are as defined in the description and in the claims, as well as pharmaceutically acceptable salts thereof.
These compounds inhibit the formation of coagulation factors Xa, IXa and thrombin induced by factor VIIa and tissue factor.
Provided is a novel compound which shows an antagonistic effect against T-type calcium channels, and is useful as a pharmaceutical product.
A compound represented by general formula (I), and a pharmaceutical agent containing the same, are disclosed:
wherein n represents the number of nitrogen atoms contained in the 6-membered fused aromatic ring, and is 0, 1 or 2; p represents the number of nitrogen atoms contained in the 6-membered aromatic ring, and is 0 or 1; X represents an oxygen atom, —SO2— or —N(R9)—; and R1 to R5 each represents a hydrogen atom or other substituents.
