摘要:
Therapeutic xanthine oxidase inhibitor composition containing as an active ingredient 3-dimethylamino-7-methyl-1,2-(n-propylmalonyl)-1,2-dihydro-1,2,4-benzotriazine dihydrate of the formula ##STR1## Uratic diathesis in warm-blooded animals is therapeutically treated by administering the aforementioned xanthine oxidase inhibitor to such animals, e.g., human, either orally or by means of an injection, thereby inhibiting their xanthine oxidase activity.
摘要:
Novel hydrazines are disclosed in which one of the nitrogen atoms forms a ring member of the five membered ring of a [4.3.0] heterobicyclic compound which may be substituted elsewhere in the ring system. Characteristic ring systems described include indole and benztriazole ring systems. The compounds possess anti-depressant properties as well as anti-microbial, in particular fungistatic and bacteriostatic, properties.

摘要:
Novel compounds of the formula (1) ##STR1## wherein R.sup.1 and R.sup.2 are different lower alkyls and R.sup.3 is a lower alkyl or a methyl pyridine group, and the acid addition salts of formula (1) compounds when R.sup.3 is methyl pyridine. The novel compounds have an asymmetric C-atom and may be in the form of the D,L racemates or the D or L stereoisomers.These compounds are useful in the treatment of hypercholesterolemia and hyperlipidemia because of their high effectiveness in reducing the level of cholesterol and lipids in the blood combined with very low general toxicities and substantially reduced hepatomegalitic effects.

摘要:
1H- and 2H- indazole derivatives and pharmaceuticals containing these blood-pressure lowering 1H- and 2H- indazole derivatives of the formula ##STR1## and their acid addition salts, wherein R1 may be in position 1 or position 2 on the nitrogen atoms in formula I. The groups R1, R2 and R3 represent hydrogen or the usual lower molecular groups. The R group is a 2-imidazolinylamino group or a 3,4,5,6-tetryhydropyrimidinylamino group, wherein these groups may also be present in their tautomeric forms. These groups may also be in an aryl group in the R1 group, in which case the R group may also be a halogen atom. R may only represent one of the heterocyclic secondary or tertiary amino groups in the 4 or 7 position for the 1H- indazole derivatives when the R1 group is simultaneously an aryl or an aralkyl group.
摘要:
Novel alkylene glycol derivatives of the formula (1) ##STR1## in which R.sup.1 is the hydrogen atom, an alkyl group having 1-4 C-atoms or an aryl group, R.sup.2 is the hydrogen atom or an alkyl group having 1-4 C-atoms, R.sup.3 is the hydrogen atom or a group of the formula ##STR2## in which Z is an alkyl residue, an optionally substituted aryl residue or a heterocyclic residue and R.sup.4 is a residue of the formula ##STR3## in which R.sup.5 is the hydrogen atom or chlorine atom, or the methyl group, exhibit an advantageous activity in regard of lowering the cholesterol and triglyceride level in the blood. Production of the novel derivatives by reduction of the corresponding acids, or by reacting a phenol of the formula ##STR4## and an alcohol of the formula ##STR5## optionally with subsequent esterification, is described.
摘要:
4-(2-Imidazolin-2-yl-amino)-2-methyl-indazole is a highly selective and effective .alpha..sub.2 -antagonist, .alpha..sub.1 -partial agonist and .alpha..sub.1s -agonist and displays anti-hypertensive activity and antagonistic activity on adrenaline and noradrenaline.
