Abstract

The search for antiepileptic compounds with more selective activity continues to be an area of intensive investigation in medicinal chemistry. 3,5-Disubstituted tetrahydro-2H-1,3,5-thiadiazine-2-thione (THTT) derivatives, 3a-g, potential prodrugs incorporating the neurotransmitter GABA were synthesized and studied for crossing the blood-brain barrier (BBB). Compounds were prepared from primary amines and carbon disulfide to give dithiocarbamates 2a-g which upon reaction in situ with formaldehyde provided the intermediates Ia-g. Addition of Ia-g onto GABA furnished the title compounds 3a-g. The structures were verified by spectral data and the amounts of the compounds in the brain were investigated by using HPLC. The concentration profiles of the tested compounds in mice brain were determined and the in vivo anticonvulsant activity was measured.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
