DCLK1-IN-1, also known as OUN35154, is a selective, oral bioavailability in vivo-compatible chemical probe of the doublecortin like kinase 1 (DCLK1 kinase) domain. CLK1-IN-1 inhibits DCLK1 and DCLK2 kinases (IC50: DCLK1=9.5/57.2 nM and DCLK2=31/103 nM in binding and kinase assay, respectively). DCLK1-​IN-​1 will serve as a versatile tool to study DCLK1 biol. and establish its role in cancer.

How to use

In Vitro:

DCLK1-IN-1 shows no significant activity against ERK5, ACK, and LRRK2. DCLK1-IN-1 potently binds DCLK1 in HCT116 cells (IC50 = 279 nM). DCLK1-IN-1 significantly inhibited DCLK1, and weakly inhibited ERK5, in PATU-8988T cell lysates and live cells.

In Vivo:

DCLK1-IN-1 has a favorable pharmacokinetic profile in mice, with a half-life of 2.09 hours, an area under the curve of 5, 506 h/ng ml and 81% oral bioavailability.
