摘要:
Acaricidal and insecticidal compositions containing as active ingredient a combination of (7-chloro-bicyclo[3,2,0]-hepta-2,6-dien-6-yl)dimethyl phosphate (I) with 2-sec.butyl-4,6-dinitrophenyl-3-methyl crotonate (II) or with 2-sec.butyl-4,6-dinitrophenyl-isopropyl carbonate (III) in a proportion by weight of compounds I:II or I:III in the range of from 1:20 to 20:1 have a synergistic effect against acaridae and their eggs and simultaneously against insects.
摘要:
Novel amine and amidine derivatives of di-0-(n-higher alkyl and alkenyl)-glycerols and -propanediols, and their pharmaceutically acceptable acid addition salts, are useful for combating viral infections in mammals. Of particular interest is 1,3-di-0-(n-hexadecyl)-2-0-(3-aminopropyl)-glycerol, and its pharmaceutically acceptable acid addition salts.
