PBT 1033 (PBT 2) is an orally active copper/zinc ionophore. PBT 1033 restores cognition in mouse models of Alzheimer's disease (AD). PB 1033 also has antibacterial activity against Gram-positive bacteria[1][2]. | [in vivo]
PBT 1033 (30 mg/kg/d, p.o., 11 days) restores biochemical substrates of learning/memory in a mouse model of alzheimer's disease[5].
| Animal Model: | Female Tg2576 mice[5] | | Dosage: | 30 mg/kg/d | | Administration: | Oral administration, 11 days | | Result: | Increased hippocampal apical spine density, basal spine density.
