RN277
Based on 1 Customer Validation
RN277 is a selective LRRK2 inhibitor with an IC50 of 135 nM against LRRK2RCKW kinase. RN277 inhibits LRRK2-mediated phosphorylation of Rab8a. RN277 rescues the motor activity of kinesin inhibited by LRRK2RCKW in vitro, and its mechanism of action may involve preventing LRRK2 from forming filamentous structures on microtubules. RN277 can be used in studies related to Parkinson's disease.

Biological Activity
RN277 (4 h) inhibits LRRK2RCKW-mediated phosphorylation of its physiological substrate Rab8a in vitro, with an IC50 of 70 nM[1].
RN277 (0.25-5 µM; 4 h) dose-dependently inhibits LRRK2-mediated Rab8a phosphorylation in 293T cells, reducing the phosphorylation level to near background at 5 µM, without affecting the S935 phosphorylation of LRRK2[1].
RN277 (5 µM; 10 min pre-incubation with LRRK2RCKW, 5 min incubation with microtubules) restores the microtubule motility of K560-GFP kinesin inhibited by LRRK2RCKW[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Concentration:0.25, 0.5, 1, 2.5, 5, 250, 500, 1, 2.5, 5 µM
-
Incubation Time:4 h
-
Result:Reduced Rab8a phosphorylation in a dose-dependent manner.
Reduced phosphorylated Rab8a to near background levels at 5 µM, comparable to the positive control MLi-2.
Did not significantly reduce phosphorylation of the LRRK2 biomarker site S935.

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: ≥ 2.5 mg/mL (4.27 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: 2.5 mg/mL (4.27 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 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 (25.0 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.
