Tyrphostin A51 是一种有效的蛋白酪氨酸激酶 (PTK) 抑制剂。Tyrphostin A51 以剂量依赖性方式抑制 [3H]牛磺酸的体积依赖性释放。Tyrphostin A51 显着降低细胞酪氨酰磷酸化水平。Tyrphostin A51 抑制基础和 EGF 诱导的人骨细胞增殖。- 高纯度，全球文献引用。

2015年7月1日 · A simple fluorescent iodide ion sensor was fabricated. Ag+ was found to specifically induce the aggregation of perylene–3, 4, 9, 10–tetracarboxylate tetrapotassium salt (PTK) in water ...

This study reports that the PTK inhibitor AG 879 inhibits proliferation of human breast cancer cells through an effect involving inhibition of MAP kinase activation, but which cannot be explained by effects of AG 879 on its known PTK targets. Instead, AG 879 markedly inhibits expression of the RAF-1 gene, which encodes an upstream MAP kinase ...

Ag + was found to specifically induce the aggregation of perylene–3, 4, 9, 10–tetracarboxylate tetrapotassium salt (PTK) in water, simultaneously, fluorescence of PTK was quenched. The resultant PTK–Ag + aggregates showed a "turn–on" fluorescence response for halide ion, especially I - , and excellent selectivity toward possible ...
