Disposition of the diastereoisomer of mefloquine in mice

H ChungJ E Sanders


The disposition of the diastereoisomer of mefloquine, WR 177,602 . HCl, was examined over a 168-hour period after 10 mg/kg of the 14C-labeled drug was administered orally to female albino ICR mice. This drug was absorbed readily. 2 h after dosing, the drug was distributed throughout the animal body with a large percent of the administered dose found in the eyes, submaxillary salivary glands, lungs, spleen, liver, gallbladder plus bile, kidney and carcasses. The elimination half-life of the unmetabolized WR 177,602 in plasma was estimated to be 16.1 h. The major route of excretion of the drug was via the feces (70%), with 23% in the urine 168 h. The elimination half-lives of the unmetabolized drug in urine and feces were 8.0 and 6.9 h, respectively. The disposition of WR 177,602 . HCl was similar to its erythrodiastereoisomer in female mice.

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.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
