SLD1121
Based on 1 Customer Validation
SLD1121 is an agonist of the Wnt/β-catenin signaling pathway that enhances Wnt signaling by targeting LRP6 (Kd: 4.52-7.49 nM). SLD1121 interacts with the intracellular domain of LRP6, stabilizes LRP6, promotes its nuclear translocation, and facilitates its binding to β-catenin, TCF4 or LEF1 in the nucleus, thereby inducing the expression of Wnt-regulated genes and stem cell-related genes. SLD1121 induces the transition of hair follicles from telogen to anagen in the mouse hair growth cycle and promotes hair growth in mice. SLD1121 is applicable to hair loss-related research.

Description
In Vitro
SLD1121 (0-2 μM; 24 h) activates the LRP6-mediated Wnt/β-catenin signaling pathway in HEK293T cells, with an EC50 of approximately 0.21 μM[1].
SLD1121 (1-2 μM; 24 h) activates the Wnt/β-catenin signaling pathway in HaCaT cells[1].
SLD1121 (0.25-2 μM; 4-24 h) dose- and time-dependently increases the levels of total LRP6 protein, phosphorylated LRP6 protein, as well as ABC and β-catenin in HEK293T and HaCaT cells, without altering the mRNA expression level of LRP6[1].
SLD1121 (2 μM; 24 h) directly interacts with LRP6 in HEK293T cells and increases the thermal stability of both endogenous and exogenous LRP6[1].
SLD1121 (0-2 μM; 12-24 h) promotes the nuclear translocation of LRP6 and increases the nuclear β-catenin level in HaCaT cells[1].

Increased anagen-phase hair follicle numbers and dermal thickness compared to vehicle-treated mice (remained in telogen) via histological H&E staining.
Upregulated protein levels of phosphorylated LRP6, total LRP6, ABC, β-catenin, cytokeratin 15, and cytokeratin 17 significantly via western blotting.
Increased expression of LRP6, β-catenin, ABC, cytokeratin 15, cytokeratin 17, and proliferative marker Ki67 in skin tissues confirmed via immunohistochemical staining.
Increased expression of Sox2 and Snail in hair follicles shown via immunofluorescence staining.

Solvent & Solubility
In Vitro:
DMSO : 14.29 mg/mL (34.40 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 (stored under nitrogen). 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: ≥ 1.43 mg/mL (3.44 mM); Suspended solution
This protocol yields a suspended solution of ≥ 1.43 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 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.
