Chemical Structure
ML281
- CAS No.: 1404437-62-2
- Formula:C22H19N3O2S
- Molecular Weight:389.47
IUPAC Name: N-(4-isopropyl-2-(3-oxo-3,4-dihydroquinoxalin-2-yl)phenyl)thiophene-2-carboxamide
InChIKey: HWOYIOLMBQSTQS-UHFFFAOYSA-N
SMILES: O=C1NC2=CC=CC=C2N=C1C3=CC(C(C)C)=CC=C3NC(C4=CC=CS4)=O
Biological Activity: ML281 is a highly selective inhibitor of serine/threonine kinase 33 (STK33) with an IC50 value of 14 nM. ML281 shows 700-fold selectivity over PKA and 550-fold over AurB. ML281 exerts core mechanism by inhibiting STK33: in small cell lung cancer, ML281 downregulates RPS6/BAD signaling phosphorylation, induces apoptosis, and suppresses proliferation, invasion[1]. ML281 reduces STK33-mediated 4-hydroxyphenylpyruvate dioxygenase (HPD) phosphorylation in tyrosinemia [4]. ML281 is suitable for research on STK33 function, KRAS mutation-related cancers (pancreatic cancer, colon cancer, lung adenocarcinoma, etc.), small cell lung cancer, and tyrosinemia-related damage[1][2][4]
