Chemical Structure
BBO-10203
- CAS No.: 2971769-60-3
- Formula:C34H30F2N6O3S
- Molecular Weight:640.70
InChIKey: CHKHXOHYIIZDNQ-LJQANCHMSA-N
SMILES: CN(N=C1)C(C=C2)=C1C=C2C3=NC(C4=NN5C([C@@H](C)N(C(C=C)=O)CC5)=C4)=[C@]([C@]6=C(F)C=C(F)C=C6OCCOC)C7=C3C=CS7
Biological Activity: BBO-10203 is a potent inhibitor of PI3Kα and KRASG12C, selectively and covalently binding to Cys242 in the RAS-Binding Domain of PI3Kα, and inhibiting both the GTP-bound and GDP-bound states of KRASG12C with an IC50 of 0.031 nM and an EC50 of 0.02 nM. BBO-10203 disrupts the interaction between RAS isoforms and PI3Kα, leading to the inhibition of RAS-mediated PI3Kα activation, and reduces pERK expression, cell growth, and induces G1 arrest and apoptosis. BBO-10203 can be used for the research of breast cancer, colorectal cancer, and non-small cell lung cancer[1][2].
