Chemical Structure
DCAI
- CAS No.: 299165-92-7
- Formula:C11H12Cl2N2
- Molecular Weight:243.13
IUPAC Name: 2-(4,6-dichloro-2-methyl-1H-indol-3-yl)ethan-1-amine
InChIKey: JCTJISIFGZHOFY-UHFFFAOYSA-N
SMILES: CC(NC1=C2C(Cl)=CC(Cl)=C1)=C2CCN
Biological Activity: DCAI is a KRas inhibitor with a Kd value of 1.1 mM. DCAI directly binds to the Ras protein and competitively inhibits SOS-mediated nucleotide release (IC50 = 155 μM) and exchange reaction (IC50 = 342 μM). DCAI binds to the pocket at the Ras-SOS interface and blocks the formation of the Ras-SOS complex intermediate by impeding salt bridge formation through steric hindrance and the induction of Ras conformational changes. DCAI is used in the study of wild-type and mutant Ras tumors[1][2].
