LRRK2-IN-1

Research use only, not for human use.

A potent LRRK2 inhibitor with IC50s of 13 nM/6 nM for wild-type/G2019S mutant LRRK2 repectively (0.1 mM ATP in the assay).

A potent LRRK2 inhibitor with IC50s of 13 nM/6 nM for wild-type/G2019S mutant LRRK2 repectively (0.1 mM ATP in the assay); shows modest activity against LRRK2 A2016T (IC50=2.45 uM) and LRRK2 A2016T+G2019S mutant (IC50=3.08 uM); also inhibits DCLK1 (IC50=2.61 nM) and 2 (IC50=45 nM); induces dephosphorylation of Ser910 and Ser935 of LRRK2 and alters the cytoplasmic localisation of LRRK2.

Wild-type and G2019S transduction results in 2.5 fold higher TR-FRET signal which can be inhibited by LRRK2-IN-1 in a dose-dependent manner with IC50 values of 0.08 μM and 0.03 μM, respectively. LRRK2-IN-1 possessed an IC50 of 45 nM for inhibition of DCLK2 and exhibits an IC50 of greater than 1 μM when evaluated in biochemical assays for AURKB, CHEK2, MKNK2, MYLK, NUAK1, and PLK1. LRRK2-IN-1 is confirmed to inhibit MAPK7 with an EC50 of 160 nM. LRRK2-IN-1 induces a dose dependent inhibition of Ser910 and Ser935 phosphorylation accompanied by loss of 14-3-3 binding to both wild type LRRK2 and LRRK2[G2019S] stably transfected into HEK293 cells. LRRK2-IN-1 is moderately cytotoxic with IC50 of 49.3 μM in HepG2 cells. LRRK2-IN-1 exhibits genotoxicity in the presence and absence of S9 at 15.6 and 3.9 μM, respectively. LRRK2-IN-1 inhibits proliferation, migration, and induces cell death with hallmarks of apoptosis of HCT116 and AsPC-1 cells.

LRRK2-IN-1 (100 mg/kg, i.p.) induces dephosphorylation of LRRK2 in the kidney of the mice. Peritumoral injection of LRRK2-IN-1 (100 mg/kg) results in a significant decrease in tumor volume and weight of AsPC-1 tumor xenografts.
