Chemical Structure
GPS167
- CAS No.: 3034312-19-8
- Formula:C17H13N5OS
- Molecular Weight:335.38
InChIKey: CYVGSDYVNUNREA-UHFFFAOYSA-N
SMILES: O=C(C1=CSC(NC2=CC=CC=C2)=N1)NC3=CC4=C(NN=C4)C=C3
Biological Activity: GPS167 is a CLK kinase inhibitor that potently and selectively inhibits recombinant human CLK1, CLK2 and CLK4. By inhibiting CLK-mediated phosphorylation of SRSF10, GPS167 upregulates the protein-binding ability of CLK1 and CLK4 with SRSF10, downregulates oncogenic BCLAF1-L and upregulates tumor-suppressive BCLAF1-S, regulates alternative splicing of genes such as MDM2 and MDM4, stabilizes p53 protein and induces DNA damage, ultimately triggering tumor cell apoptosis. GPS167 can block the epithelial-mesenchymal transition process of tumors, activate intracellular double-stranded RNA-mediated antiviral immune responses, and produce synergistic cytotoxicity when combined with microtubule-targeting drugs. GPS167 can be used in research related to various cancers including colorectal cancer[1][2][3].
