A cell-permeable pyridinylbutanone compound that inhibits cellular autophosphorylation of both the wild-type Jak2 and the constitutively active V167F mutant (IC₅₀ = 15 & 28 µM, respectively, with WT- & V617F-transfected BSC-40 cells), while exhiting no effect against cellular Tyk2 autophosphorylation in COS cells or c-Src kinase in cell-free kinase assays. Z3 suppresses the Jak2-V167F-dependent proliferation of the erythroleukemia cell line HEL by blocking the G1-S transition and is shown to effectively reduce the cytokine-stimulated growth of both Jak2-V617F-positive and Jak2-F537I-positive primary hematopoietic progenitor cells from myeloproliferative disorder patients.，官网链接：https://www.sigmaaldrich.cn/product/mm/420141 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
