R3 is hydrogen or a substituent selected from the group consisting of —CH2C(═CH2)—COOR, —COOCH2C(═CHR)—COOR, —COOCH2OCOR, —COOCH(R)OCOR, —COOCH(R)OCOOR, —COOCH(OCOR)OCOR, —COOCH2COCH2OCOR, and
with the proviso that one of R2 and R3 is hydrogen and the other is not hydrogen,
R is hydrogen or C1-6-alkyl;
R4 is hydrogen or hydroxy,
R5 is hydrogen or &ohgr;-hydroxyalkyl; and
X is CH or N,
pharmaceutically acceptable salts of the compounds and hydrates of the compounds and of their salts.
