Abstract: The present technology is directed to polypropionate lactone stereotetrads of Formula (I) (or a pharmaceutically acceptable salt and/or solvate thereof) which are significant intermediates for multiple synthetic applications.
Abstract: A pyridoxine-based compound of formula 1: exhibits a high level of antiepileptic activity. At doses of 25, 50 and 100 mg/kg, compound 1 completely suppresses the epileptic electrical activity of the brain within an hour after intraperitoneal administration to rats on the penicillin model of epilepsy. The rats' corazol model of epilepsy shows a decrease in intensity and duration of seizures with the administration of compound 1 at doses of 25 and 100 mg/kg intraperitoneally and 100 and 200 mg/kg orally, and the complete prevention of seizures in some cases at a dosage of 250 mg/kg with oral administration. Compound 1 is low toxic. The LD50 parameter in rats exceeds 2000 and 5000 mg/kg of body weight with intraperitoneal and oral administration respectively. The technical solution provides a new highly effective and safe drug for the treatment of epilepsy.
