生物活性

ICI 198583 is a thymidylate synthase (TS) inhibitor with a Ki value of 10 nM for both mouse and human TS. ICI 198583 serves as a substrate for folylpolyglutamate synthetase (FPGS) with a Km of 40 μM. ICI 198583 exerts persistent, dose-dependent inhibition on thymidylate synthase flux in mice. ICI 198583 is applicable to relevant research on leukemia[1].

体外研究
(In Vitro)

ICI 198583 可强效抑制部分纯化的小鼠胸苷酸合成酶 (TS) 和人源胸苷酸合成酶 (TS),其 Ki 为 10 nM[1]
ICI 198583 可作为部分纯化的小鼠肝脏 FPGS 的底物,其 Km 为 40 μM[1]
ICI 198583 可在体外强效抑制 L1210 细胞 (IC50 = 0.085 μM) 和 W1L2 细胞 (IC50 = 0.056 μM) 的增殖,对过量表达 DHFR 的 L1210:R7A 细胞仍具有活性,而对还原型叶酸转运缺陷型 L1210:1565 细胞的活性降低 96 倍[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
