Abstract

Oral administration of o-chloro 2-phenyl éthyl allophanate (S. C. S. 100) to male and pregnant, or not, female mice, to male and female rats, to male guinea-pigs and rabbits induces, according to tested doses and animal species, a reduction of motoricity, a state of sleepiness giving way to exterior solicitations, a loss of balance, a diminution of muscular tonus or a temporary loss of righting reflex going with narcosis and a reversible suppression of sensibility. The narco-hynoticaction of S. C. S. 100 qualitatively similar to that of secobarbital needs 1.5 to 3 times higher doses to appear and has a little longer latent period but without any excitation. The new synthesized molecule differs also from the barbiturate as its therapeutic index is 3 times more important which means a better maniability confirmed moreover in mouse after several repeated administrations of ED 50 doses of S. C. S. 100.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
