(Cell-free assay)
10-19 nM(EC50)
시험관 내(In vitro)
Birabresib (OTX015)는 92에서 112 nM 범위의 IC50으로 BRD2, BRD3 및 BRD4의 AcH4 결합을 억제하고, 60에서 200 nM 범위의 GI50으로 다양한 인간 암세포주의 성장을 억제합니다. 이는 c-MYC 발현의 급격한 하향 조절을 유도하며, ALKpos ALCL 세포주에서 ALK 억제제와 병용 시 시너지 항증식 효과를 보입니다.
키나아제 분석
TR-FRET 분석
Birabresib (OTX015)의 BRD2, BRD3 및 BRD4 결합을 평가하기 위해, BRD 발현 CHO 세포 용해물(Flag-태그된 BRD2, BRD3 또는 BRD4 발현 플라스미드 또는 벡터만으로 형질감염된 CHO 세포에서 유래), 유로퓸-접합된 Anti-Flag 항체, XL-665-접합된 스트렙타비딘 및 비오틴화된 이들을 실온에서 0.2에서 2시간 동안 배양합니다. 형광은 EnVision 2103 Multilabel Reader를 사용하여 TR-FRET로 측정하며, 결합에 대한 EC50은 PRISM 버전 5.02를 사용하여 비선형 회귀로 계산됩니다.
생체 내(In vivo)
Birabresib (OTX015)는 경구 투여(p.o.) 시 누드 마우스에서 Ty82 BRD-NUT 중간선 암종 종양의 성장을 100 mg/kg qd에서 79%, 10 mg/kg bid에서 61% 유의하게 억제합니다.
