Leucettinibs are substituted 2-aminoimidazolin-4-ones (inspired by the marine sponge natural product Leucettamine B) developed as pharmacological inhibitors of DYRK1A (dual-specificity, tyrosine phosphorylation-regulated kinase 1A), a therapeutic target for indications such as Down syndrome and Alzheimer’s disease. Leucettinib-21 was selected as a drug candidate following extensive structure/activity studies and multiparametric evaluations. We here report its physicochemical properties (X-ray powder diffraction, differential scanning calorimetry, stability, solubility, crystal structure) and drug-like profile. Leucettinib-21’s selectivity (analyzed by radiometric, fluorescence, interaction, thermal shift, residence time assays) reveals DYRK1A as the first target but also some “off-targets” which may contribute to the drug’s biological effects. Leucettinib-21 was cocrystallized with CLK1 and modeled in the DYRK1A structure. Leucettinib-21 inhibits DYRK1A in cells (demonstrated by direct catalytic activity and phosphorylation levels of Thr286-cyclin D1 or Thr212-Tau). Leucettinib-21 corrects memory disorders in the Down syndrome mouse model Ts65Dn and is now entering safety/tolerance phase 1 clinical trials.

唐氏综合症和阿尔茨海默病候选药物 Leucettinib-21 的化学、生化、细胞和生理学表征



Leucettinib 是取代的 2-氨基咪唑啉-4-酮(受海绵天然产物 Leucettamine B 启发)开发为 DYRK1A(双特异性、酪氨酸磷酸化调节激酶 1A)的药理学抑制剂,DYRK1A 是唐氏综合症和糖尿病等适应症的治疗靶点。阿尔茨海默氏病。经过广泛的结构/活性研究和多参数评估后,Leucettinib-21被选为候选药物。我们在此报告其理化性质(X 射线粉末衍射、差示扫描量热法、稳定性、溶解度、晶体结构)和药物样特征。 Leucettinib-21 的选择性(通过辐射、荧光、相互作用、热位移、停留时间分析进行分析)表明 DYRK1A 是第一个靶点,但也有一些“脱靶”可能有助于药物的生物效应。 Leucettinib-21 与 CLK1 共结晶并以 DYRK1A 结构建模。 Leucettinib-21 抑制细胞中的 DYRK1A(通过 Thr286-cyclin D1 或 Thr212-Tau 的直接催化活性和磷酸化水平证明)。 Leucettinib-21 可纠正唐氏综合症小鼠模型 Ts65Dn 的记忆障碍,目前正进入安全性/耐受性 1 期临床试验。
