  Design and Synthesis of Novel DFG-Out RAF/Vascular Endothelial Growth Factor Receptor 2 (VEGFR2) Inhibitors. 1. Exploration of [5,6]-Fused Bicyclic Scaffolds

  摘要：

  To develop RAF/VEGFR2 inhibitors that bind to the inactive DFG-out conformation, we conducted structure-based drug design using the X-ray cocrystal structures of BRAF, starting from an imidazo[1,2-b]pyridazine derivative. We designed various [5,6]-fused bicyclic scaffolds (ring A, 1-6) possessing an anilide group that forms two hydrogen bond interactions with Cys532. Stabilizing the planarity of this anilide and the nitrogen atom on the six-membered ring of the scaffold was critical for enhancing BRAF inhibition. The selected [1,3]thiazolo[5,4-b]pyridine derivative 6d showed potent inhibitory activity in both BRAF and VEGFR2. Solid dispersion formulation of 6d (6d-SD) maximized its oral absorption in rats and showed significant suppression of ERK1/2 phosphorylation in an A375 melanoma xenograft model in rats by single administration. Tumor regression (T/C = -7.0%) in twice-daily repetitive studies at a dose of 50 mg/kg in rats confirmed that 6d is a promising RAF/VEGFR2 inhibitor showing potent anticancer activity.

  N-methylation of the amine linker could control the twisted molecular conformation leading to improved solubility. These approaches produced N-methyl thiazolo[5,4-b]pyridine-5-amine derivative 5. To maximize the in vivo efficacy, we attempted salt formation of 5. Our result indicated that the besylate monohydrate salt form (5c) showed significant improvement of both solubility and oral absorption. Owing to

  我们的目的是发现具有强活性和足够口服吸收的RAF /血管内皮生长因子受体2（VEGFR2）抑制剂，因此，我们选择了5-氨基连接的噻唑并[5,4- d ]嘧啶衍生物作为前导物化合物具有潜在的激酶抑制活性和所需的溶解性。根据BRAF的X射线共晶体结构数据，设计了新颖的1-氰基-1-甲基乙氧基叔取代基，以占据BRAF“后袋”的疏水区域。另外，我们发现胺连接基的N-甲基化可以控制扭曲的分子构象，从而导致溶解度的提高。这些方法产生了N-甲基噻唑并[5,4 - b ]吡啶-5-胺衍生物5。为了使体内功效最大化，我们尝试了5的成盐作用。我们的结果表明，苯磺酸盐一水合物盐形式（5c）在溶解度和口服吸收方面均表现出显着改善。由于改善的理化特性，化合物5c在HT-29异种移植模型中显示出了抗肿瘤退行的功效。

  the oral absorption of thiazolo[5,4-b]pyridine 1, we investigated novel N-acyl imide prodrugs of 1 as RAF/vascular endothelial growth factor receptor 2 (VEGFR2) inhibitors. Introducing N-acyl promoieties at the benzanilide position gave chemically stable imides. N-tert-Butoxycarbonyl (Boc) introduced imide 6 was a promising prodrug, which was converted to the active compound 1 after its oral administration
