approved CML drug that is active against the ABL1(T315I) mutation. However, ponatinib has severe cardiovascular toxicities; hence, there have been efforts to find safer CML drugs that work against ABL1 secondary mutations. We reveal that isoquinoline‐ or naphthyridine‐based compounds, such as HSN431, HSN576, HSN459, and HSN608 potently inhibit the enzymatic activities of ABL1, ABL1(T315I), and ABL1(E255K)
伊马替尼引入临床彻底改变了慢性粒细胞白血病(CML)的治疗。 CML 的总体八年生存率已从 20 世纪 70 年代的约 6% 提高到伊马替尼时代的 90% 以上。然而,约 20% 的 CML 患者对酪氨酸激酶抑制剂具有原发性或获得性耐药性。 BCR-ABL1 融合蛋白中的 ABL1 点突变(例如 ABL1(T315I))通常在长期激酶抑制剂治疗后出现。 Ponatinib (AP24534) 是目前唯一批准的对 ABL1(T315I) 突变具有活性的 CML 药物。然而,ponatinib有严重的心血管毒性;因此,人们一直在努力寻找针对 ABL1 二次突变的更安全的 CML 药物。我们发现异喹啉或萘啶基化合物,如 HSN431、HSN576、HSN459 和 HSN608 有效抑制 ABL1、ABL1(T315I) 和 ABL1(E255K) 的酶活性。这些化合物抑制 ABL1 驱动的 CML
