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].
PB 1033 displays antibacterial activity against S. uberis, with a MIC value of 14.5 μM[2].
PBT2 (1, 3 and 7.5 μM, 6 h) protects neurons against glutamate-induced excitotoxicity[3].
PBT2 (10 μM, 1 or 6 h) reduces NMDAR-mediated Ca2+ flux in mouse cortical neurons[3].
PBT2 (0-10 μM, 1 h) increases GSK3α/β phosphorylation in SH-SY5Y cells[4].
PBT2 (20 μM, 1 h) prevents the formation of Zn-induced protease resistant Aβ aggregates[5].
Western Blot Analysis[4]

| Concentration: | 0-10 μM |
| Incubation Time: | 1 h |
| Result: | Increased in cellular levels of GSK3α/β phosphorylated at the inhibitory serine 21/9 residue (ser21/9 on GSK3α/β). |
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. |

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
