NEW MATERIAL:The titled compound shown by the formula I (R is H or CN; X is halogen; n is 0 or 1). EXAMPLE:alpha-Cyano-3-(4-chloroanilino)benzyl alpha-isopropyl-4-chlorophenyl acetate. USE:An insecticide and acaricide. Especially having improved insecticidal action against Nephotettix cin...
Since cuprizone-induced demyelination is largely mediated by toxicity rather than immune attacks, therefore this finding suggests Yhhu4952 might directly act on oligodendrocytes. EAE is another common animal model that shares many pathological similarities to MS, and most therapies or modifying agents ...
is substantially enhanced. It is also noted that the efficiency of the PeLEDs exhibits an initial rise before the prolonged decay process starts. This phenomenon is commonly observed in PeLEDs13,33,34,35,36and is so far speculated to be related to ion migration36or trap filling/defect ...
Phenyl chloroformate is incompatible with strong oxidizing agents, alcohols, amines, alkali. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Health Hazard TOXIC; inhalation, inge...
There is also some evidence of anticonvulsant activity against seizures evoked by PTZ at 30 min after administration of 2-deoxy-d-glucose at doses of 200–400 mg/kg i.p. and 50–400 mg/kg per os (p.o.), but overall the results were not sufficient to calculate an ED50 or a time ...
is Me, Br, Cl or SMe; on the other hand, predominant 3-phenylation is seen when 2-X is CO2Me, SO2Me or NO2. When the substituent is at position 3, the two effects reinforce each other, so that 2-phenylation is the major result. Obviously, the relative stability of the σ-...
