the mechanism of anticancer activity of the studied compounds PASS software was used and these compounds were assayed for the inhibition of CK1γ and CK2α kinases. The reported series of 1,2,4-triazolin-5-thiones inhibits CK1γ and CK2α kinases in micromolar range. The most active compound shows activity against isoform γ3 which at concentration of 50 μM reduced the kinase activity by 69% while at 100
新的CK2和CK1抑制剂的优化和合成是开发新的治疗策略的基础,用于治疗与这些酶的过表达和功能异常相关的癌症和神经退行性疾病。三唑衍生物作为潜在的激酶抑制剂似乎特别令人感兴趣。在这种情况下,我们合成了一系列1,2,4-三唑啉-5-硫酮衍生物作为CK1γ激酶抑制剂。评估了合成化合物对癌细胞的抗增殖活性:人肺腺癌(A549),人肝癌(HepG2)和人乳腺腺癌(MCF-7)。化合物1表现出针对A549癌细胞的抗增殖能力,并且其特征在于选择性的抗增殖作用。此外,该化合物对A549,HepG2,在这些细胞系中,MCF-7细胞仅诱导少量坏死细胞。为了解释所研究化合物的抗癌活性机理,使用了PASS软件,并测定了这些化合物对CK1γ和CK2α激酶的抑制作用。报道的一系列1,2,4-三唑啉-5-硫酮在微摩尔范围内抑制CK1γ和CK2α激酶。最具活性的化合物显示出对同工型γ3的活性,当浓度为50μM时,其激酶活
