Studies on uricosuric diuretics. III. Substituted 1,3-dioxolo[4,5-f]-1,2-benzisoxazole-6-carboxylic acids and 1,3-dioxolo[4,5-g]-1,2-benzisoxazole-7-carboxylic acids

A series of substituted 1,3-dioxolo[4,5-f]-1,2-benzisoxazole-6-carboxylic acids 13 and 1,3-dioxolo[4,5-g]-1,2benzisoxazole-7-carboxylic acids 14 were synthesized and evaluated for diuretic and uricosuric activities in rats. Most of the benzisoxazole deriv

Benzodioxole derivatives

The invention relates to novel benzodioxole derivatives of the formula I STR1 in which R1 represents an unsubstituted or substituted, aromatic or heteroaromatic radical, alk represents an alkylene or alkylidene radical having a maximum of 5 carbon atoms, n represents O or 1, R2 and R3 each represents, independently of the other, hydrogen, lower alkyl, lower alkoxy or halogen, and A represents the radical O-R4, wherein R4 represents hydrogen or an unsubstituted or substituted, aliphatic or araliphatic hydrocarbon radical, or A represents the radical STR2 in which either R5 and R6 each represents, independently of the other, hydrogen or lower alkyl, or R5 and R6 are bonded to one another and, together with the adjacent nitrogen atom, represent unsubstituted or lower alkyl-substituted tetra- or hexa-methyleneimino or 4-morpholinyl, to salts of compounds of the formula I in which A represents OR4 wherein R4 is hydrogen, with bases, and to acid addition salts of compounds of the formula I in which the radical R1 has a basic character, and to pharmaceutical compositions that contain them. The novel substances exhibit diuretic and, in addition, uricosuric activity and may be administered, according to the invention, preferably in the form of appropriate pharmaceutical compositions, to mammals for the treatment of oedema and hypertension.

Benzodioxole derivatives and pharmaceutical use thereof

The invention relates to novel benzodioxole derivatives of the formula I STR1 in which R1 represents an unsubstituted or substituted, aromatic or heteroaromatic radical, alk represents an alkylene or alkylidene radical having a maximum of 5 carbon atoms, n represents 0 or 1, R2 and R3 each represents, independently of the other, hydrogen, lower alkyl, lower alkoxy or halogen, and A represents the radical O--R4, wherein R4 represents hydrogen or an unsubstituted or substituted, aliphatic or araliphatic hydrocarbon radical, or A represents the radical STR2 in which either R5 and R6 each represents, independently of the other, hydrogen or lower alkyl, or R5 and R6 are bonded to one another and, together with the adjacent nitrogen atom, represent unsubstituted or lower alkyl-substituted tetra- or hexa-methyleneimino or 4-morpholinyl, to salts of compounds of the formula I in which A represents OR4 wherein R4 is hydrogen, with bases, and to acid addition salts of compounds of the formula I in which the radical R1 has a basic character, and to pharmaceutical compositions that contain them.
