Two series of inhibitors of type III phosphatidylinositol-4-kinase were identified by high throughput screening and optimised to derive probe compounds that independently and selectively inhibit the alpha- and the beta-isoforms with no significant activity towards related kinases in the pathway. In a cellular environment, inhibition of the alpha- but not the beta-subtype led to a reduction in phos
通过高通量筛选鉴定了两个系列的III型磷脂酰肌醇4-激酶抑制剂,并对其进行了优化,以衍生出能够独立,选择性地抑制α-和β-同工型而对路径中相关激酶没有明显活性的探针化合物。在细胞环境中,抑制α-亚型而不抑制β-亚型会导致4-磷酸磷脂酰肌醇和-4,5-磷酸二磷酸肌醇浓度的降低,从而导致肌醇-1-磷酸形成的抑制和增殖的抑制。一组癌细胞系。
