Description

PKMYT1-IN-9 is a highly selective and orally active PKMYT1 inhibitor (IC50: 4.4 nM). PKMYT1-IN-9 shows more selective for PKMYT1 than WEE1 (IC50: 32.4 μM). PKMYT1-IN-9 exhibits antitumor activity[1].

IC50 & Target[1]

PKMYT1

4.4 nM (IC50)

In Vitro

PKMYT1-IN-9 (Compound 36) (7 d) has strong antiproliferative effect on the HCC1569 cell lines (CC50: 0.31 μM) and weak antiproliferative effect on the KYSE30 cell lines (CC50: >30 μM)[1].
PKMYT1-IN-9 inhibits EPHA1 kinase (IC50: 10.1 nM), but is less potent on the other six kinases (ABL1, ABL2, BRAF, CSF1R, LCK, and SRC) (IC50: >60 nM)[1].
PKMYT1-IN-9 is non-GSH-reactive, non-hERG-inhibitory, has low CYP inhibition (<50%), and has high clearance in human and mouse liver microsomes (77.3 mL/min/kg at 1 mg/kg IV)[1].

In Vivo

PKMYT1-IN-9 (Compound 36) (15 mg/kg, p.o., twice daily for 21 d) can inhibit tumor growth (53%) in NOD-SCID female mice in the HCC1569-derived tumor xenograft (CDX) mouse model[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
