  Discovery of the Novel Potent and Selective FLT3 Inhibitor 1-{5-[7-(3- Morpholinopropoxy)quinazolin-4-ylthio]-[1,3,4]thiadiazol-2-yl}-3-p-tolylurea and Its Anti-Acute Myeloid Leukemia (AML) Activitiesin Vitroandin Vivo

  摘要：

  Structure-activity relationship (SAR) studies of 2-(quinazolin-4-ylthio)thiazole derivatives, which are for optimizing the in vitro and in vivo antiacute myeloid leukemia (AML) activity of a previously identified FLT3 inhibitor 2-(6,7-dimethoxyquinazolin-4-ylthio)thiazole (1), are described. SAR studies centering around the head (thiazole) and tails (6- and 7-positions) of the quinazoline moiety of 1 led to the discovery of a series of compounds that exhibited significantly dincreased potency against FLT3-driven AML MV4-11 cells. Preliminary in vivo assays were carried out on three highly active compounds, whose results showed that 1-{5-[7-(3-morpholinopropoxy)quinazolin-4-ylthio]-[1,3,4]thiadiazol-2-yl}-3-p-tolylurea (20c) had the highest in vivo activity. Further in vitro and in vivo anti-AML studies were then performed on 20c; in an MV4-11 xenograft mouse model, a once-daily dose of 20c at 100 mg/kg for 18 days led to complete tumor regression without obvious toxicity. Western blot and immunohistochemical analysis were carried out to illustrate the mechanism of action of 20c.

  The present disclosure relates to bifunctional compounds, which find utility as modulators of FLT3 (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hppel-Lindau, cereblon, ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds the target protein FLT3, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of the target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

  本公开涉及双功能化合物，它们可用作 FLT3（靶蛋白）的调节剂。特别是，本公开涉及双功能化合物，其一端含有与 E3 泛素连接酶结合的 Von Hppel-Lindau（脑龙）配体，另一端含有与靶蛋白 FLT3 结合的分子，从而将靶蛋白置于泛素连接酶附近，以实现对靶蛋白的降解（和抑制）。本公开物具有与降解/抑制靶蛋白相关的广泛药理活性。本公开的化合物和组合物可以治疗或预防因目标蛋白聚集或积聚而导致的疾病或失调。
