MS-39 Chemical Properties, Uses, Production
Uses
MS39 (compound 6) is a PROTAC targeting EGFR. MS39 is composed of PROTAC target protein ligand N-(3-Chloro-4-fluorophenyl)-7-methoxy-6-(3-(piperazin-1-yl)propoxy)quinazolin-4-amine (HY-W109039) (red part), E3 ligase ligand (S,R,S)-AHPC (HY-125845) (blue part) and PROTAC Linker Undecanedioic acid (HY-W014125) (black part), among which the conjugate of E3 ubiquitin ligase ligand + Linker is (S,R,S)-AHPC-CO-C9-acid (HY-139345). MS39 reduces the expression of EGFR and downstream signaling in HCC-827 and H3255 cells. MS39 inhibits the proliferation of H3255 cells[1].
