  Discovery of New Benzothiazole-Based Inhibitors of Breakpoint Cluster Region-Abelson Kinase Including the T315I Mutant

  摘要：

  The existence of drug resistance caused by mutations in the break-point cluster region-Abelson tyrosine kinase (Bcr-Abl) kinase domain remains a clinical challenge due to limited effective treatment options for chronic myeloid leukemia (CML). Herein we report a novel series of benzothiazole-based inhibitors that are effective against wild-type and T315I mutant Bcr-Abl kinases. The original hit compound, nocodazole, was extensively modified through a structure-based drug design strategy, especially by varying the groups at the C2 and C6 positions of the scaffold. In addition, the introduction of water-solubilizing groups at the terminal ethyl group resulted in enhanced physicochemical properties and potency in cellular inhibition. Several compounds inhibited the kinase activity of both wild-type Bcr-Abl and the T315I mutant with IC50 values in the picomolar range and exhibited good antiproliferative effects on Ba/F3 cell lines transformed with either wild-type or T315I mutant Bcr-Abl.

  this study addresses the critical need for novel therapeutic approaches. We have identified the sodium-coupled citrate transporter (NaCT or SLC13A5) as a target for intervention. Utilizing rational drug design, we developed a new class of SLC13A5 inhibitors, anchored by the hydroxysuccinic acid scaffold, refining the structure of PF-06649298. Among these, LBA-3 emerged as a standout compound, exhibiting

  面对主要由现代生活方式因素驱动的代谢性疾病患病率不断上升，这项研究满足了对新型治疗方法的迫切需求。我们已确定钠偶联柠檬酸转运蛋白（NaCT 或 SLC13A5）作为干预目标。利用合理的药物设计，我们开发了一类新型SLC13A5抑制剂，以羟基琥珀酸支架为锚定，完善了PF-06649298的结构。其中， LBA-3成为一种突出的化合物，表现出显着的效力，IC 50值为 67 nM，显着优于PF-06649298 。体外试验证明了LBA-3在降低 OPA 诱导的 HepG2 细胞中甘油三酯水平方面的功效。此外， LBA-3在不同的小鼠模型（PCN 刺激和饥饿诱导）中表现出优异的药代动力学特性，并有效降低甘油三酯和总胆固醇水平，且没有可检测到的毒性。这些发现不仅凸显了LBA-3作为高脂血症治疗的有希望的候选者，而且还证明了靶向分子设计在推进代谢性疾病治疗方面的潜力。
