The present invention relates to a substituted thiazolo[3,2-a]azepine derivative having inhibitory activity against angiotensin I converting enzyme and neutral endpeptidase.
The above substituted thiazolo[3,2-a]azepine derivative is represented by the following general formula (I):
(wherein R1 represents a hydrogen atom or a protecting group of a thiol group; R2 represents a hydrogen atom, a lower alkyl group, an aryl group which may have a substituent, a hetroaryl group which may have a substituent, a lower alkoxyl group or a lower alkylthio group; R3, R4 and R5 may be the same or different from one another and represent each a hydrogen atom, a lower alkyl group, a lower alkoxyl group, a lower alkylthio group or the like, with the proviso that the case wherein all of R3, R4 and R5 are hydrogen atoms are excepted;
R6 and R7 may be the same or different from each other and represent each a hydrogen atom or a lower alkyl group; R8 represents a hydrogen atom or a protecting group of a carboxyl group; and
m and m are each independently 0 or, 1 or 2).
