9-Decyn-1-ol is an alkyl ether-based PROTAC linker suitable for synthesizing PROTACs. It serves as a conjugation agent to combine GDC-0068 and Lenalidomide, resulting in the formation of INY-03-041. INY-03-041 is a potent and highly selective pan-Akt degrader that operates through the PROTAC mechanism. It effectively inhibits Akt1, Akt2, and Akt3 with IC50 values of 2.0 nM, 6.8 nM, and 3.5 nM, respectively[1].
Ipatasertib-NH2 (GDC-0068-NH2;RG7440-NH2) is a ligand for the target protein AKT used in PROTAC, binding to lenalidomide, a ligand of ubiquitin E3 ligase cereblon (CRBN), via a ten-hydrocarbon linker to form INY-03-041 for AKT degradation[1].
Divarasib (GDC-6036) adipate is a selective and highly potent KRAS G12C inhibitor with an impressively low IC 50 value of <0.01 μM, designed for oral administration. It covalently attaches to the switch II (SW-II) pocket in KRAS G12C, irreversibly maintaining the protein in its inactive GDP-bound state [1] [2].
