RGLS4326
Based on 1 publication(s) in Google Scholar
RGLS4326 (RG4326) is a microRNA-17 (miR-17) oligonucleotide inhibitor with an EC50 of 28.3 nM. RGLS4326 antagonizes AMPAR and inhibits ligand binding. RGLS4326 relieves the inhibition of Pkd1/Pkd2 by miR-17 and upregulates PC1/PC2. RGLS4326 preferentially distributes to the kidney and cysts, attenuates cyst progression and improves survival in mouse models of autosomal dominant polycystic kidney disease (ADPKD) in a miR-17 binding motif-dependent manner. RGLS4326 can be used in ADPKD-related research.

In Vitro
RGLS4326 inhibits the function of GluA2-homotetrameric AMPARs in HEK293 cells[1].
RGLS4326 (200 µM; 30 min) binds GluA2-γ2 LBD via 3’G, stabilizes the open clamshell/closed pore state, and provides the structural basis for competitive AMPAR inhibition[1].
RGLS4326 (5-10 μM; 24-72 h) derepresses miR-17 PD-Sig in isolated mouse kidney slices and shows low pro-inflammatory gene induction in rat tissue slices[3].
RGLS4326 (8 days) derepresses miR-17 targets, increasing PC1 by approximately 2-fold and PC2 by approximately 4-fold, and reduces cyst growth in primary human ADPKD cyst cultures[3].
RGLS4326 is metabolically stable in mouse, monkey, and human tissue lysates[3].
RGLS4326 (10 μM; 24 h) inhibits miR-17 and derepresses the miR-17 luciferase sensor in HeLa cells with an EC50 of 28.3 nM[3].

RGLS4326 (25 mg/kg; s.c.; QW or Q4W; 25 weeks) reduces cyst burden in Pcy/CD1 mice when administered early, whereas late intervention is ineffective[3].
RGLS4326 (1-25 mg/kg; s.c.; QW; 9 weeks) dose-dependently reduces kidney weight-to-body weight ratio and cyst index in Pcy/DBA mice, whereas monthly dosing is ineffective[3].
