產(chǎn)品描述: | Selitrectinib (LOXO-195, BAY 2731954) 是一種具有口服活性、高度有效的、選擇性TRK激酶抑制劑,對TRKA G595R、TRKC G623R和TRKA G667C的IC50值為2-9.8 nM。它對靶點的選擇性是對其他98%所檢測的非TRK激酶的1000倍以上 |
靶點: |
WT TRKA(Celll-free assay):0.6 nM; TRKA G595R(Cell-free assay):2 nM; TRKC G623R(Cell-free assay):2.3 nM; WT TRKC(Cell-free assay):2.5 nM; TRKC G696A(Cell-free assay):2.5 nM;TRKA G667C:9.8 nM;Trkreceptor |
體外研究: |
LOXO-195在體外能有效地抑制不同的活化TRK激酶。在濃度為1 μM時,LOXO-195對目標靶點的選擇性比對98%其他檢測激酶(庫中包含228種激酶)高1000倍以上。在包含TRK融合的KM12、CUTO-3和O-91細胞系中,LOXO-195能有效地抑制其細胞增殖(IC50 ≤ 5 nmol/L)。而在不包含TRK融合的84種細胞系中,濃度即使高達10 μM的LOXO-195對細胞生長也沒有抑制作用 |
體內(nèi)研究: |
在由ΔTRKA驅(qū)動的腫瘤中,LOXO-195有效地減少磷酸化TRKA水平。在四種依賴于TRKA的腫瘤模型中(通過接種包含NIH 3T3 ΔTRKA, ΔTRKA G595R, ΔTRKA G667C和TPM3-NTRK1融合的KM12細胞構(gòu)建的腫瘤模型),LOXO-195可引起腫瘤生長抑制作用 |
