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. It is useful as an .alpha.-adrenoceptor influencing and as an anti-hypertensively active drug.
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 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:
A process for the manufacture of imidazolylvinyl ethers of the formula ##STR1## wherein Im represents the substituted or unsubstituted 1-H-imidazol-1-yl group and An, R and Y are defined hereinbelow by condensation of a corresponding ketone of the formulaAr--CO--CHR--Im (II)with the splitting-off of a Z group, with a condensable substance of the formulaZ--Y (III)in the aqueous solution of a strong inorganic base, preferably in concentrated aqueous soda lye. The reaction may also be carried out in the presence of a second liquid organic phase, preferably benzene or toluene, especially in the presence of a phase transfer catalyst in this case. Through careful crystallization of the product manufactured according to this method, it is possible to manufacture approximately pure E-isomers of the imidazolylvinyl ether of formula (I), without the requirement of chromatographic separation.
摘要:
Aryl-imidazol-1-yl vinyl ethers and their acid addition salts are disclosed, wherein the imidazolyl vinyl ether has the formula: ##STR1## Ar in the formula represents a substituted or unsubstituted aryl or heterocyclic radical; R represents hydrogen or a C.sub.1 -C.sub.12 alkyl or cycloalkyl (saturated or unsaturated) or Ar as above; Im represents a 1-H-imidazol-1-yl group (unsubstituted or substituted); and Y represents a saturated or unsaturated C.sub.1 -C.sub.12 alkyl or a group --Z--Ar in which Ar has the above meaning and --Z-- is a saturated or unsaturated C.sub.1 -C.sub.12 alkylene wherein each of the alkyl and the alkylene may have a carbon chain once or twice interrupted by or, in the case of the alkylene, terminated on its Ar-end by oxy, thio, sulfinyl or sulfonyl bridges, always with the proviso that at least one of Ar and Y is a heterocyclic radical. These compounds are wide-spectrum fungicides and bactericides, and the preferred compounds among them are hydrophilic.

These compounds are effective wide spectrum fungicides and bactericides.
摘要:
This invention relates to novel thioethers as well as to the addition salts thereof with inorganic or organic acids. The novel compounds and their addition salts have valuable anti-mycotic and fungicidal properties. Further the invention relates to a process for preparing the novel compounds and their addition salts, and to anti-mycotic and fungicidal compositions containing the novel thioethers, or addition salts thereof, as the active constituent.

.alpha.-Aryl-.beta.-imidazol-1-yl vinyl ethers and their acid addition salts are disclosed, wherein the imidazolyl vinyl ether has the formula: ##STR1## Ar represents a substituted or unsubstituted aryl group, R an alkyl, aryl or aralkyl group, X an oxygen atom, a sulfur atom, a sulfinyl or a sulfonyl group and R1 a lower alkyl group or a nitro group. These compounds are effective wide spectrum fungicides and bactericides. To prepare these vinyl ethers, a corresponding 1-arylacylimidazole is o-alkylated in presence of NaH with a corresponding .alpha.-halogen ether, .alpha.-halogen thioether, .alpha.-halogen sulfinyl compound or a corresponding .alpha.-halogen sulfonyl compound.
