摘要:
An antiviral drug contains as its effective component an isothiosemicarbazone represented by the following general formula (I) or an acidic salt thereof: ##STR1## wherein R.sub.1 represents a halogen atom, a lower (C.sub.1 -C.sub.6) alkyl group, a hydroxy group, a phenyl group which may be or may not be substituted with an alkoxy group containing 1 to 12 carbon atoms, or an unsubstituted or substituted phenylethynyl group represented by the following general formula (II): ##STR2## (wherein R.sub.5 and R.sub.6 may be the same or different, and they each represent a hydrogen atom, a halogen atom, a lower (C.sub.1 -C.sub.6) alkyl group, a hydroxy group or an alkoxy group containing 1 to 12 carbon atoms); R.sub.2 represents a hydrogen atom or a lower (C.sub.1 -C.sub.6) alkyl group; R.sub.3 represents a lower (C.sub.1 -C.sub.6) alkyl group or a benzyl group; R.sub.4 represents a hydrogen atom or a lower (C.sub.1 -C.sub.6) alkyl group. Many of these effective component compounds not only have antiviral activity (especially against influenza virus), but also prevent the breeding of and exterminate plant pathogenic molds.
摘要:
Triiodoallyl- or iodopropargyl-substituted heterocyclic aromatic compounds which can be prepared by reacting unsubstituted- or substituted nitrogen-containing heterocyclic compounds with corresponding iodine containing alcohol reactive derivatives in the presence of a base in an inert organic solvent. These new heterocyclic aromatic compounds have remarkable antibacterial and antifungal activities and are useful as antibacterial and antifungal agents in medicinal, agricultural and industrial fields.
摘要:
A sulfonylsemicarbazide derivative of the general formula (I) is effective as a preservative agent for preserving the freshness of a flower, which can prolong the vase life of the flower petals of cut flowers where the flowers can be enjoyed. ##STR1## wherein R.sup.1 represents a (C.sub.3 -C.sub.4)-alkyl group, a substituted or unsubstituted phenyl group, a pyridyl group, a thio-phenyl group or others, R.sup.2 and R.sup.3 each independently represent a hydrogen atom, a lower alkyl group, an alkoxalyl group, an alkoxyalkyl group, a group of the formula --C(X)--X--R.sup.4 where X means an oxygen atom or a sulfur atom and R.sup.4 means an alkyl group, or other, or R.sup.2 and R.sup.3 may form a heterocyclic ring having 4 to 5 carbon atoms or a group of the formula --N.dbd.CR.sup.5 (R.sup.6), as taken with the --N atom to which R.sup.2 and R.sup.3 are attached.
摘要:
A novel compound represented by the formula (I) ##STR1## wherein R represents a lower alkyl group having 1 to 4 carbon atoms which has an intense microbicidal activity over a wide range of microorganisms and is applicable to a microbicide.
摘要:
The present invention relates to pyrazolylpyrimidine derivatives of the formula ##STR1## wherein X, R.sub.1, R.sub.2 and R.sub.3 are as herein defined. These compounds are useful as fungicides in agriculture and horticulture.
摘要:
Triiodoallyl- or iodopropargyl-substituted tetrazole compounds which are prepared by reacting substituted tetrazole compound with reactive derivatives of corresponding triiodoallyl alcohol or iodopropargyl alcohol or by iodinating propargyltetrazole compounds, as well as antibacterial and antifungal compositions for medicinal, agricultural and industrial fields which contain as active ingredient said tetrazole compounds.
