摘要:
N-[(alkylamino)alkyl]3,4 (or 4,5)-diaryl-1H-pyrazole-1-(branched)alkanamides and pyrazole-1-alkanamines useful for treating cardiac arrhythmias in mammals, are prepared by reacting a lower-alkyl ester of pyrazole-1-acetic acid with an appropriate diamine followed by reduction or by reacting the anion of a lower-alkyl ester of a pyrazole-1-acetic acid with an alkylating agent followed by displacement of the ester by an appropriate amine.
摘要:
Compositions for cleaning hard surfaces, which are formulated to leave on the surface simultaneously with the cleaning thereof a protective barrier layer which serves to protect the surface against further soil deposition comprising: (A), as cleaning agents, from one to two nonionic surfactants and an amphoteric surfactant; (B) as protective barrier components, lecithin and an aminofunctional polydimethylsiloxane copolymer; (C), as solvency and grease cutting agents, from one to two glycols; and (D) water.
摘要:
The method of increasing ovulation rate and litter size in swine which comprises administering to a gilt or sow during the middle to late part of the estrus cycle an amount of epostane sufficient to increase follicular recruitment and thereby increase the number of ova released by the ovaries and, after insemination, to increase the number of viable fertilized ova implanted in the uterus and, after gestation, to increase the number of live piglets delivered is described.
摘要:
N-[(disubstituted amino)alkyl]-3,4 (or 4,5)-diaryl-1H-pyrazole-1-acetamides and pyrazole-1-propanamides, useful for treating cardiac arrhythmias in mammals, are prepared by reacting a lower-alkyl ester or pyrazole-1-acetic or propanoic acid with an appropriate diamine or by reacting a lower-alkyl ester of a pyrazole-1-acetic or propanoic acid with an ω-aminoalkanol, followed by activation of the alcohol and displacement of an appropriate amine.
摘要:
The method of regulating fertility in swine which comprises administering to a pregnant sow near term an amount of epostane sufficient to induce parturition of live piglets on the following day.
摘要:
3-Arylcarbonyl- and 3-cycloalkylcarbonyl-1-aminoalkyl-1H-indoles, useful as analgesic, anti-rheumatic and anti-inflammatory agents, are prepared by reacting a 3-arylcar- bony or 3-cycloalkylcarbonylindole with an aminoalkyl halide in the presence of an acid-acceptor; by reacting a 1-aminoalkyl-1H-indole with an arylcarboxylic acid halide or a cycloalkanecarboxylic acid halide in the presence of a Lewis acid; or by reacting a 3-arylcarbonyl- or 3-cycloalka- necarbonyl-1-tosyloxyalkyl- or haloalkyl-1H-indole with an amine.
摘要:
A dispenser for automatically metering a liquid-soluble or liquid-suspendible material into a liquid environment in response to a rise and fall in the level of the liquid which comprises a buoyant container adapted for holding the material to be dispensed, said container being adapted for pivotal mounting on an axis which is offset from the axis of the center of buoyancy of said container by an amount from greater than 0% up to about 200% of the distance, a measured along a line through the pivot axis, between said center of buoyancy axis and the outer perimeter of said container, said container having one or more openings in a wall thereof located below the center of buoyancy of said container.
摘要:
2- and/or 6-pyridylethylamino-substituted fluorans useful as color formers, particularly in pressure-sensitive carbonless duplicating systems and thermal-responsive marking systems are prepared by the interaction of (pyridylethylaminophe- nyl)carbonylbenzoic acids with 4-hydroxy- or alkoxyanilines or by the interaction of (disubstituted aminophenyl)carbonylben- zoic acids with N-pyridylethyl-4-hydroxy- or alkoxy acetanilides. The (pyridylethylaminophenyl)carbonylbenzoic acid intermediates required for the fluorans are prepared by interacting a N-pyridylethyl-3-hydroxyaniline with a substituted or unsubstituted phthalic anhydride. The N-pyridylethyl-4-hydroxy-or alkoxyanilines and the N-pyridylethyl-3-hydroxyanilines are prepared by interacting the respective aniline with a vinylpyridine.
