Abstract
The invention relates to novel derivatives of 4-amino-3-(piperazin-1-yl or homopiperazin-1-yl)quinazoline, which can be used as regulators of the cardiovascular system, and are especially suitable for treating high blood pressure. The compounds have the formula I <IMAGE> in which (R)n represents a 6,7-di(lower alkoxy) or 6,7,8-tri(lower alkoxy) radical; m = 1 or 2, X represents the radical -CHR<1>- or -CH2CH2-; each of the radicals R<1>, which may be identical or different to the others, represents a hydrogen atom or a lower alkyl radical; and R<2> and R<3>, which may be identical or different, each represent a hydrogen atom, a lower alkyl radical, lower alkoxy radical, a halogen atom, a lower alkanoyl radical, lower alkoxy carbonyl radical or a radical of the formula -CONR<4>R<5> or -SO2NR<4>R<5>, in which R<4> and R <5>, which may be identical or different, each represent a hydrogen atom or a lower alkyl radical; the compounds may also be present in the form of their pharmaceutically acceptable acid addition salts.
