体外研究 (In Vitro) | PROTAC SOS1 degrader-1 (compound 9d) (0.1, 1 μM) shows SOSI degradation activity with an SOS1 protein degradation of 56.2 and 92.5% at 0.1 and 1 μM, respectively[1]. PROTAC SOS1 degrader-1 (0-2000 nM; 24 h) exhibits SOS1 degradation activity with an DC50of 98.4 nM in a dose- and time-dependent manner in NCI-H358 cells[1]. PROTAC SOS1 degrader-1 (0-2500 nM; 24 h) dose-dependently reduced the SOS1 protein level but showed no effect on SOS2 and KRAS up to 2.5 μM in NCI-H358 and AsPc-1 cells[1]. PROTAC SOS1 degrader-1 (0-2000 nM; 24 h) reduces the expression of KRAS-GTP, induced ERK phosphorylation with an IC50value of 72.3 nM, and significantly increases the pERK level after 6-24 h[1].
