med chem Flashcards
drugs with 3 ring structure and urea like carbonyl
carbamazepine
oxcarbazepine
eslicarbazepine
drugs with amino acid backbone and alkane group
gabapentin
pregabalin
what gives Na ion channels voltage gated activity
helix 4
what amino acids make up the pore in K channels
G-Y-G
what amino acids make up the pore in Ca channels
glutamate
what amino acids make up the pore in Na channels
several, lots of variation
factors that determine ion channels selectivity
- metal ion coordination number
- ligand strenght
- pore size, rigidity, and solvent exposure
metal ion coordination number
number of donor atoms attached (in our case usually water)
drug with linker region and its importance
tiagabine (GABA uptake inhibitor)
-interacts with positive region of transporter, more electronegative linker the better it binds
drug that irreversibly binds to GABA aminotransferase
vigabatrin
pregabalin original design
to inhibit GABA aminotransferase, then thought to agonize GAD
pregabalin function for antiseizure activity
binds voltage gated Ca channels and prevents glutamate release
phase I metabolism reactions
oxidation, hydrolysis
phase 2 metabolism reactions
conjugation to make it more polar (sulfaiton, glucuronidation, ubiquitination, etc)
perampanel MoA
noncompetitive AMPA antagonist
