生物活性

KG-FP-003 is a highly potent, selective, and durable TEAD PROTAC degrader (TEAD1 DC50 = 6 ± 4 nM, TEAD2 DC50 = 68 ± 15 nM, TEAD3 DC50 = 12 ± 5 nM, TEAD4 DC50 = 7 ± 5 nM). KG-FP-003 promotes ubiquitination and degradation of TEAD. KG-FP-003 exhibits anticancer activity against mesothelioma and ovarian cancer[1].

KG-FP-003 以 591 ± 21 nM 的 IC50 结合重组 CRBN-DDB1ΔBPB 蛋白[1]
KG-FP-003 (以 10 μM 的浓度进行 3 倍梯度稀释; 2 h) 在过表达 NanoLuc-CRBN 的 HEK293T 细胞中与 CRBN 结合,在细胞结合实验中的 IC50 为 962 ± 86 nM[1]
KG-FP-003 (6 h) 可在处理 6 h 后强效且选择性地降解 HiBiT 标记 HEK293T 细胞中的全部四种 TEAD 亚型 (TEAD1 DC50 = 6 ± 4 nM, TEAD2 DC50 = 68 ± 15 nM, TEAD3 DC50 = 12 ± 5 nM, TEAD4 DC50 = 7 ± 5 nM)[1]
KG-FP-003 (72 h) 可强效抑制 NCI-H226 间皮瘤细胞的增殖,处理 72 h 后的 IC50 为 27 ± 7 nM[1]

Real Time qPCR[1]

Cell Line: MSTO-211H mesothelioma cells
Concentration: 300 nM
Incubation Time: Unclear
Result: Induced dramatic upregulation of the pro-apoptotic gene BMF and downregulation of the TEAD target gene CTGF.

Cell Cycle Analysis[1]

Cell Line: MSTO-211H mesothelioma cells
Concentration: 100-1000 nM
Incubation Time: 24 h
Result: Increased the percentage of cells in G1 phase from 54.3% to 62.1% at 100 nM, and to 65.2% at 1000 nM, indicating G1 phase cell cycle arrest.

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.
