REM127
Based on 1 Customer Validation
REM127 is an orally active, blood-brain barrier-penetrant septin 6/7 molecular glue degrader. REM127 binds to SEPT6 with high affinity and promotes the assembly of SEPT2/6/7 cortical filaments, thereby normalizing cytoplasmic calcium levels, cerebrospinal fluid hyperphosphorylated tau protein levels, synaptic function and cognitive function. REM127 can be used in research related to Alzheimer's disease.

Descripciòn
In Vitro
REM127 restores calcium homeostasis, improves synaptic function, reduces Alzheimer's disease-related tau and Aβ pathology, and rescues survival of neuronal cells challenged with pathological tau or Aβ[1].
REM127 (15-19 nM) potently reduces tauP301L-induced toxicity and restores calcium homeostasis in neuronally differentiated human neuroblastoma cells with EC50 values of 15 nM and 19 nM, respectively[2].
REM127 restores dendritic spine density and rescues primary rat hippocampal neurons from ADDL-induced cell death[2].
REM127 selectively normalizes tauP301L-induced aberrant SOCE and elevated basal cytoplasmic calcium levels in human neuroblastoma cells without affecting physiological calcium signaling in control cells[2].
REM127 selectively normalizes elevated SOCE in patient iPSC-derived tauP301L-expressing glutamate-releasing neurons without affecting physiological SOCE in isogenic control neurons[2].
REM127 reduces tauP301L-induced increases in ER-PM contact area in human neuroblastoma cells[2].
REM127 normalizes calcium2+-dependent NFAT signaling by inhibiting tauP301L-induced NFAT nuclear translocation in human neuroblastoma cells[2].
REM127 restores cortical septin filament organization disrupted by tauP301L expression in human neuroblastoma cells[2].
REM127 fully rescues hyperexcitability in patient iPSC-derived tauP301L-expressing glutamate-releasing neurons over 20 days of treatment[2].

In Vivo
REM127 (20 mg/kg; p.o.; once daily; for 7-14 consecutive days) restores hippocampal long-term potentiation in APP-Ln transgenic mice, and normalizes brain oscillatory activity after 14 days of administration[2].
REM127 (20 mg/kg; p.o.; once daily; for 3 months) reduces Aβ plaque burden and microglial inflammation levels in double-transgenic mice[2].
REM127 (25 mg/kg; p.o.; once daily; for 3 months) reduces dense-core amyloid plaques, Aβ42 production, and phosphorylated tau protein aggregation in APP-SAA knock-in mice[2].

Solvente y solubilidad
In Vitro:
DMSO : 50 mg/mL (119.23 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.25 mg/mL (2.98 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 1.25 mg/mL (2.98 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1.25 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
