INDY is a selective inhibitor of Dyrk1A and Dyrk1B with IC50 values of 0.23 and 0.24 μM, respectively [1].

Dual-specificity tyrosine-(Y) -phosphorylation-regulated kinase 1A (Dyrk1A) is a serine/threonine kinase expressed in adult brains as well as fetal and phosphorylates myriad proteins. DYRK1B regulates nuclear functions mainly expressed in muscle and testis [1].

INDY is a selective Dyrk1A and Dyrk1B inhibitor. INDY inhibited Dyrk1A against ATP with Km and Ki of 37 and 0.18 μM, respectively. INDY (10 μM) exhibited > 90% inhibition on CLK1, CLK4, DYRK2, DYRK3, casein kinase 1 (CSNK1D) and PIM1. In COS7 cells, INDY (3 μM) inhibited tau-phosphorylation induced by Dyrk1A. In HEK293 cells, Dyrk1A inhibited the nuclear accumulation of NFATc1, while INDY relocated NFATc1 into the nucleus [1]. In EGFR-expressing glioblastomas tumor-initiating cells (GBM-TICs), INDY impaired cells self-renewal capacity and inhibited tumor growth and survival [2].

In X. laevis embryo overexpressed xDyrk1A, deformity was observed in the head and the eye of stage 40/41 tadpoles. While proINDY rescued the morphological abnormalities [1].
