Examines the physiology of olfaction, general observations on olfaction, odor and molecular structure, problems in the study of olfaction, the classification of odors, and current theories and studies of olfaction.
either direction) when their effects are transmitted to the reducible group.
ExperimentalCinnamic Acids.-irons-Cinnamic acid was an Eastman Kodak White Label sample. ¡ -Nitrocinnamic acid was prepared by nitration of cinnamic acid and purified via its ethyl ester.11 1p-Iodocinnamic acid was prepared by iodination of cinnamic acid with iodine in acetic acid in the presence of nitric acid12 and purified by chromatography on magnesol and elution with acetone.o-and p-methyl-, chloro-, and bromo-, m-nitro-, and p-hydroxyand -methoxy-, as well as p-iodocinnamic acids were prepared by reaction of the appropriate benzaldehyde with malonic acid in 95% ethanol in the presence of piperidine.13 o-and m-hydroxy-and methoxy-and o-nitrocinnamic acids were prepared similarly in pyridine solution with piperidine.14 o-and m-methoxybenzaldehydes were prepared by methylation of the hydroxybenzaldehyde with methyl sulfate and sodium hydroxide.16 o-and p-chloro-and bromobenzaldehydes were (11) W.
Disodium phosphonoacetate when administered orally or topically to mice experimentally infected with herpes simplex virus was able to significantly reduce the mortality associated with the agent. In addition, this compound was able to reduce herpesvirus lesions on the corneas of infected rabbits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
