Novel compounds of the formula: ##STR1## wherein X is a lower alkanoyloxy group or a substituted thio group, where the substituent is a nitrogen-containing heterocyclic group, or a pharmaceutically acceptable salt or ester thereof, have a broad antimicrobial spectrum, and besides they are readily absorbed into the living body. Thus, the compounds are useful as therapeutic agent for various bacterial infections of animals including human beings.
摘要:
Novel cephalosporin compounds of the formula ##STR1## wherein R.sup.1 is an acyl group and R.sup.2 is an alkylene group which may be substituted with a lower alkoxyl group, or pharmaceutically acceptable salt thereof, have strong inhibitory actions on broad spectra of gram-positive and gram-negative bacteria and, particularly against Esherichia coli and Klebsiella pneumoniae. Thus, the compounds are useful as therapeutic agent for various bacterial infections of animals including human beings.
摘要:
.alpha.-Unsaturated amines of the formula: ##STR1## wherein X.sup.1 and X.sup.2 are such that one is an electron-attracting group with the other being a hydrogen atom or an electron-attracting group; R.sup.1 is a group attached through a nitrogen atom; R.sup.2 is a hydrogen atom or a group attached through a carbon, nitrogen or oxygen atom; n is an integer equal to 0, 1 or 2; A is a heterocyclic group or a cyclic hydrocarbon group, and salts thereof and their agrochemical use as insecticidal and/or miticidal agents are described.
摘要:
##STR1## wherein R is a substituted or unsubstituted hydrocarbon residue or acyl group; X is an electron withdrawing group; Y 1 and Y 2 , which are the same or different, are each independently oxygen or sulfur; and A is a substituted or unsubstituted, divalent hydrocarbon residue have potent reactivity, this being useful in preparing guanidine derivatives.
摘要:
An insecticidal composition containing a guanidine derivative of the formula: ##STR1## wherein R.sup.1 is an optionally substituted homocyclic or heterocyclic group, n is 0 or 1, R.sup.2 is a hydrogen atom or an optionally substituted hydrocarbon group, R.sup.3 is a primary, secondary or tertiary amino group, X is an electron attractive group such as nitro or trifluoroacetyl group, provided that when n is 0, R.sup.1 is an optionally substituted heterocyclic group or a salt thereof.
摘要:
Safe and quite active termiticidal compositions for controlling termites comprising an effective amount of a compound of the formula: ##STR1## wherein R is hydrogen, a C.sub.1-6 alkyl-carbonyl group, or C.sub.1-6 alkoxy-carbonyl group; or a salt thereof and an an agrochemically acceptable vehicle, are provided. Methods for eradicating termites are also provided. The termiticidal composition exhibits an excellent activity in eradicating termites.
摘要:
Disclosed are 2-(syn)-hydroxyimino-acetamide derivatives of the formula: ##STR1## wherein Y is hydrogen, hydroxyl, an acyloxy, carbamoyloxy, a quaternary ammonium or a nitrogen-containing heterocyclic ring-substituted thio group; or pharmaceutically acceptable salts or esters thereof are useful as antibacterial agents. Also disclosed are processes for producing them.
摘要:
A compound of the formula: ##STR1## wherein R.sup.1 represents hydrogen or an alkyl group, X represents oxygen or sulfur or a group of formula --NR.sup.2 (where R.sup.2 is hydrogen or an alkyl group and in the case of alkyl, it may form a ring jointed with R.sup.1), and Y represents acetoxy group or a group of formula --SR.sup.3 (where R.sup.3 is a nitrogen-containing heterocyclic group), or a pharmaceutically acceptable salt thereof, is found to have a broad antimicrobial spectrum and, in particular, effective against gram-negative bacteria including Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Proteus morganii, as well as gram positive ones. Thus, these compounds may be used for antimicrobial agents in therapeutical purposes.
