IC50& Target[1] | |
体外研究 (In Vitro) | MRTX0902 (compound 32) (1 μM; 0, 2, 4, 8, 15, and 30 minutes) shows a moderate Clintvalue of 195 mL/min/kg in human liver microsome and a low lipophilicity with cLogP of 3.4[1]. MRTX0902 displays high selectivity on SOS1 (Ki=2 nM) over SOS2 and EGFR (both Kivalues >10,000 nM), MRTX0902 inhibits MKN1 cells with an IC50value of 29 nM[1].
