RD0448 是一种 DYRK1ADYRK1BDYRK2 抑制剂。RD0448 可选择性靶向 DYRK1A 和 DYRK1B 的非天然 (折叠中间体) 状态。RD0448 其结合位点在 DYRK1A 和 DYRK1B 天然状态下处于隐藏状态,并且作为一种稳定结合剂,可与 DYRK1A 和 DYRK1B 紧密结合,形成非快速解离的稳定复合物。RD0448 靶向 DYRK2 的天然状态,对 DYRK2 的天然状态与非天然状态无选择性,并且作为一种弱结合剂,与 DYRK2 的结合作用较弱,形成的复合物会快速解离[1]

生物活性

RD0448 is a potent inhibitor of DYRK1A, DYRK1B, and DYRK2. RD0448 selectively targets the non-native (folded intermediate) state of DYRK1A and DYRK1B. The binding site of RD0448 is hidden in the native state of DYRK1A and DYRK1B, and as a stabilizing binder, it binds tightly to both DYRK1A and DYRK1B, forming a stable complex with slow dissociation kinetics. In contrast, RD0448 targets the native state of DYRK2 without selectivity between its native and non-native states, acting as a weak binder with weaker binding affinity to DYRK2 and forming a rapidly dissociating complex[1].

体外研究
(In Vitro)

RD0448 (20 s 瞬时加热) 可选择性靶向 DYRK1A 的非天然构象,在瞬时加热条件下其 IC50 从 >64 μM 降低到 38 μM,且与 DYRK1A 结合紧密[1]
RD0448 (20 秒瞬时加热处理) 可选择性靶向 DYRK1B 的非天然构象,在瞬时加热条件下其 IC50 从 52 μM 降低到 16 μM,且能与 DYRK1B 紧密结合[1]
RD0448 (54°C 下瞬时加热 20 秒) 未选择性靶向 DYRK2 的非天然构象 (瞬时加热未提升抑制效力),其未加热和瞬时加热条件下的 IC50 分别为 31 μM 和 43 μM,且未与 DYRK2 紧密结合[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.
