51773-92-3 Usage
Description
Different sources of media describe the Description of 51773-92-3 differently. You can refer to the following data:
1. Mefloquine hydrochloride is an erythrocytic schizonticide useful, in combination
with sulfadoxine and pyrimethamine, in the prophylaxis and treatment of malaria.
Administered once weekly, the combination is effective against pathogens
resistant to other agents.
2. Mefloquine is an orally bioavailable quinolinemethanol derivative with antimalarial properties. It increases mean survival time and abolishes malarial infection in mice at doses of 10 and 40 mg/kg, respectively. It inhibits hemozoin formation, leading to an increase in free heme in purified trophozoites. It acts as an antagonist at the adenosine A2A receptor, an agonist at serotonin 5-HT2A and 5-HT2C receptors, and has various effects on calcium homeostasis. Mefloquine increases the time mice spend in the light side of the light-dark box test and reduces immobility time in the tail suspension test, parameters typically associated with anxiolytic and antidepressant-like behavior. Formulations containing mefloquine have been used to prevent and treat malaria but have been associated with neuropsychiatric disturbances.

Clinical Use
The newest of the 4-aminoquinolines,mefloquine, is marketed as the R,S-isomer. It was developedin the 1960s as part of the U.S. Army’s WalterReed Institute for Medical Research antimalarial researchprogram. It differs significantly from the other agents in this class by having two trifluromethyl moieties at positions2’ and 8' and no electronegative substituents at eitherpositions 6' (quinine) or 7' (chloroquine). Mefloquine alsodiffers from chloroquine and its analogs by being a schizonticide acting before the parasite canenter the erythrocyte. There is some evidence that it acts byraising the pH in the parasite’s vesicles interfering with itsability to process heme. Mefloquine-resistant strains ofP. falciparum have appeared. Relapse can occur with acuteP. vivax that has been treated with mefloquine because thedrug does not eliminate the hepatic phase of this species,which can reinfect the liver.Mefloquine is teratogenic in rats, mice, and rabbits. Thereis an FDA-required warning that this drug can cause exacerbatemental disorders and is contraindicated in patients withactive depression, a recent history of depression, generalizedanxiety disorder, psychosis, schizophrenia, and other majorpsychiatric disorders or a history of convulsions.
Check Digit Verification of cas no
The CAS Registry Mumber 51773-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,7 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51773-92:
(7*5)+(6*1)+(5*7)+(4*7)+(3*3)+(2*9)+(1*2)=133
133 % 10 = 3
So 51773-92-3 is a valid CAS Registry Number.
