| ln Vitro |
The phosphorylation of tau Ser396 is greatly inhibited by MPT0G211 (0.1 μM; cells were transfected with pCAX APP 695 and pRK5-EGFP-Tau P301L for 24 hours)[1]. Inhibiting HDAC6/Hsp90 binding, MPT0G211 leads to the proteasomal breakdown of polyubiquitinated proteins[1]. Tau phosphorylation is markedly reduced by MPT0G211 through GSK3β inactivation[1]. h using pRK5-EGFP-Tau P301L and pCAX APP 695)[1]. The proliferation of MDA-MB-231 and MCF-7 cells is inhibited by MPT0G211 (GI50 = 16.19 and 5.6 μM, respectively)[2]. Through the inhibition of DNA repair mechanisms and the activation of Bcl-2-associated X protein (BCL-XL)-dependent cell apoptosis, MPT0G211 enhanced the cytotoxic effects of DOXO in AML cells[3].

| ln Vivo |
The impairment in spatial memory is greatly improved by MPT0G211 (50 mg/kg; po; daily for 3 months)[1]. MPT0G211 (ip; qd; day 73 post-tumor injection; 25 mg/kg) decreases lung weights and nodule counts[2]. In addition to reducing tau phosphorylation by blocking GSK3β activity, MPT0G211 therapy increases Hsp90's acetylation, which downregulates HDAC6/Hsp90 binding and speeds up the proteasomal breakdown of polyubiquitinated p-tau[1].

| Animal Protocol |
Animal/Disease Models: Triple transgenic (3×Tg-AD) mice (harboring APPSwe and tauP301L mutant transgenes[1]
Doses: 50 mg/kg Route of Administration: Po; daily for 3 months Experimental Results: Dramatically ameliorated the spatial memory impairment. Animal/Disease Models: Female SCID (severe combined immunodeficient) mouse (bearing MDA-MB-231 cells)[2] Doses: 25 mg/kg Route of Administration: Ip; qd; day 73 post-tumor injection Experimental Results: Dramatically diminished numbers of nodules and lung weights. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.52 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
