Study of the Potential Endocrine-Disrupting Effects of Phenylurea Compounds on Neurohypophysis Cells In Vitro [PDF]

open access: yesInternational Journal of Endocrinology, 2019
Homeostatic disruptor agents, and endocrine disruptor compounds (EDC) specifically, can originate from agricultural and industrial chemicals. If they modify the adaptation of living organisms as direct (e.g., by altering hormone regulation, membrane ...

On the Thermal Dissociation of Organic Compounds. XII. The Effects of the Substituents on the Thermal Dissociation of Substituted Phenylureas [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1957
Abstract Eleven new ureas of the type, 1,1-diethyl-3-arylureas and 1-pentyl-3-arylureas were synthesized. The rate constants and ρ values of thermal dissociation of these ureas in fatty acids were determined. In 1,1-diethyl-3-arylureas, the ρ value of the dissociation reaction at 95°C.
