A focused set of heterocyclic quinones based on the benzothiazole, benzoxazole, benzimidazole, indazole and isoindole was prepared and screened with respect to the inhibition of the phosphatase activity of CDC25C. Benzoxazole- and benzothiazole-diones were at least 50 times more potent in inhibiting CDC25C than their benzimidazole-indazole- or isoindole-dione counterparts. These in vitro activities
制备了一组基于苯并噻唑,苯并恶唑,苯并咪唑,吲唑和异吲哚的杂环醌,并就抑制CDC25C的磷酸酶活性进行了筛选。苯并恶唑和苯并噻唑二酮在抑制CDC25C方面的功效至少是苯并咪唑-吲唑-或异吲哚-二酮类似物的50倍以上。这些体外活性与用Mia PaCa-2和DU-145人肿瘤细胞培养物观察到的抗增殖作用高度相关。通过WST-1比色测定获得的IC(50)值范围对于苯并恶唑或苯并噻唑二酮为0.10至0.50 microM,而对于其他杂环二酮则为10 microM以上。
