IUPAC Name: pentanoic-2,2-d2 acid
InChIKey: DOOBEITVZIIXPE-XJGHKLLTSA-N
SMILES: O=P(O)(OC[C@@H]1[C@@H](O)[C@@H](O)[C@H](N2C=NC3=C2NC(N)=NC3=O)O1)OP(OP(OC[C@@H]4[C@@H](O)[C@@H](OC)[C@H](N5C(NC(N)=N6)=C([N+](C)=C5)C6=O)O4)([O-])=O)(S)=O
Biological Activity: β-S-ARCA (3'-O-Me-m7G(5')ppp(5')G) is a mRNA 7-methylguanosine (m7G) cap analog carrying a phosphorothioate (PS) moiety. β-S-ARCA binds eIF4E via electrostatic interactions between its β-sulfur atom and positively charged Arg and Lys residues in the protein binding site. β-S-ARCA prevents the decapping by Dcp2, increases the mRNA half-life, enhances cap-dependent translation, and increases protein expression in cells. β-S-ARCA has been applied in researching experimental mRNA-based anticancer vaccines[1][2].
