Journal of Pharmaceutical Sciences, 1994
A number of arylidene derivatives of alicyclic ketones and some corresponding oximes, oxime esters, and related compounds were prepared as candidate cytotoxic agents. All of the compounds were evaluated against murine L1210 lymphoid leukemia cells. In general, cytotoxicity was greatest with the alpha,beta-unsaturated ketones and diminished with the ...

This publication is the 11th in a series of safety evaluations performed by the Expert Panel of the Flavor and Extract Manufacturers Association (FEMA). In 1993, the Panel initiated a comprehensive program to re-evaluate the safety of more than 1700 GRAS flavoring substances under conditions of intended use. The list of GRAS substances has now grown to

Reactions of Monosaccharides with Beta-Ketonic Esters and Related Substances
1956Publisher Summary This chapter discusses the reactions of monosaccharides with β-ketonic esters and related substances. It is accepted that some kind of correlation exists between the metabolism of carbohydrates and that of β-ketonic compounds, but views as to its nature differ.

Atmospheric Environment, 2007
Abstract Gas-phase rate coefficients for the atmospherically important reactions of NO3, OH and O3 are predicted for 55 α,β-unsaturated esters and ketones. The rate coefficients were calculated using a correlation described previously [Pfrang, C., King, M.D., C. E. Canosa-Mas, C.E., Wayne, R.P., 2006. Atmospheric Environment 40, 1170–1179].
