生物活性

RET-IN-32 is an orally active RET inhibitor with IC50 values of 0.285, 4.602 and 103.5 nM against wild-type, V804M and G810S mutant forms, respectively. RET-IN-32 inhibits the autophosphorylation of Tyr1062. RET-IN-32 completely suppresses tumor growth induced by BAF3-KIF3B-RET-WT xenografts. RET-IN-32 can be used in the research of thyroid cancer and lung cancer[1].

体外研究
(In Vitro)

RET-IN-32 (Compound 9) (72 h) 可抑制 BAF3-KIF5B-RET-WT 细胞的增殖,其 IC50 为 1.2 nM;同时可抑制 BAF3-KIF5B-RETV804M 细胞的增殖,其 IC50 为 212 nM[1]
RET-IN-32 (1-100 nM; 12 h) 可在 BAF3-KIF5B-RET-WT 细胞中呈剂量依赖性降低 SPRY4 和 DUSP6 的 mRNA 表达,但对 GSK3B 的 mRNA 表达无影响[1]
RET-IN-32 (1-1000 nM; 1 h) 可在 10 nM 浓度下显著抑制 BAF3-KIF5B-RET-WT 细胞中 RET Tyr1062 的自磷酸化,在 100 nM 浓度下则几乎实现完全抑制[1]
RET-IN-32 (1-1000 nM; 12 h) 可在 BAF3-KIF5B-RET-WT 细胞中诱导剂量依赖性 G0/G1 期阻滞并减少 S 期细胞群[1]
RET-IN-32 (10-1000 nM; 12 h) 可在 100 nM 和 1000 nM 浓度下诱导 BAF3-KIF5B-RET-WT 细胞发生细胞凋亡[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
