Pyridoxal kinase inhibitor
- Vitamin B6 is not converted to its active PLP form
- ↓ GABA synthesis → seizures
- Treated with pyridoxal-5-phosphate, bypassing the blocked kinase
- The ginkgotoxin seizure mechanism
Drugs with this mechanism (1)
- Ginkgotoxin — Ginkgo seed neurotoxin that blocks pyridoxal kinase, causing the pyridoxine-responsive seizures of raw ginkgo nuts.
