작용 메커니즘

특징	Stattic is the first non-peptide small molecule with inhibitory activity against STAT3 SH2 domain regardless of the STAT3 phosphorylation state in vitro.
Targets/IC₅₀/Ki	STAT3 (Cell-free assay) 5.1 μM
시험관 내(In vitro)	Stattic은 gp130 수용체에서 유래한 포스포티로신 함유 펩타이드가 STAT3 SH2 도메인에 결합하는 것을 강력한 온도 의존적인 방식으로 억제한다. 이 화합물은 티로신 인산화된 펩타이드가 티로신 키나아제 Lck의 SH2 도메인에 결합하는 데 매우 약한 영향만을 미친다. 그리고 다른 두 가지 이량체 전사 인자(c-Myc/Max 및 Jun/Jun)의 이량체화를 억제하지 않는다. 또한 플루오레세인 표지된 포스포펩타이드가 STAT1 및 STAT5b의 SH2 도메인에 결합하는 것을 억제한다. 이 화학물질은 10 μM 농도에서 STAT3 동종이량체의 DNA 결합을 선택적으로 억제한다. STAT3의 Tyr705에서의 세포 인산화를 억제하는 것으로 나타났으며, STAT1의 Tyr701에서의 인산화(HepG2 세포에서) 또는 JAK1, JAK2 및 c-Src의 인산화(MDA-MB-231 및 MDA-MB-235S 세포에서)에는 거의 영향을 미치지 않는다. 이 화합물은 STAT3 의존성 유방암 세포주의 아팝토시스 비율을 증가시킨다.
키나아제 분석	고속 스크리닝 및 형광 편광 분석
키나아제 분석	스크리닝은 약 30 °C에서 수행됩니다. 스크리닝 히트의 특이성은 STAT1, STAT5 및 Lck의 SH2 도메인에 대한 시험 화합물의 결합에 대한 유사 분석에서 검증됩니다. 모든 FP 분석에 사용되는 완충액 성분의 최종 농도는 10 mM HEPES (pH 7.5), 1 mM EDTA, 0.1% Nonidet P-40, 50 mM NaCl 및 10% DMSO입니다. Dithiothreitol의 부재는 억제 활성에 필수적입니다. 펩타이드 서열은 다음과 같습니다: STAT3, 5-carboxyfluorescein-GY(PO₃H₂)LPQTV-NH₂; STAT1, 5-carboxyfluorescein-GY(PO₃H₂)DKPHVL; STAT5, 5-carboxyfluorescein-GY(PO₃H₂)LVLDKW; 및 Lck, 5-carboxyfluorescein-GY(PO₃H₂)EEIP. 30 °C에서의 특이성 분석을 위해 단백질은 150 nM (STAT1, STAT3 및 STAT5)으로 사용됩니다. 37 °C에서의 특이성 분석을 위해 단백질은 370 nM (STAT3) 또는 100 nM (Lck)으로 사용됩니다. 단백질은 에펜도르프 튜브에서 시험 화합물과 지정된 온도에서 60분 동안 배양한 후 해당 5-카르복시플루오레세인 표지된 펩타이드를 첨가합니다 (최종 농도: 10 nM). 실온에서 측정하기 전에 혼합물은 최소 30분 동안 평형을 이루도록 합니다. 시험 화합물은 DMSO에 20배 희석된 재고 용액에서 지정된 농도로 사용됩니다. 결합 곡선 및 억제 곡선은 SigmaPlot으로 피팅됩니다. 모든 경쟁 곡선은 독립적인 실험에서 세 번 반복됩니다.
