While proteasome inhibitors such as bortezomib showed satisfactory clinical benefits in the initial treatment of multiple myeloma (MM), drug resistance and relapse are unavoidable. Recent studies suggested inhibition of histone deacetylases (HDACs) restored sensitivity of bortezomib-resistant MM. Hence, we designed dual inhibitors targeting both HDACs and proteasomes to address the resistance of bortezomib
尽管蛋白酶体抑制剂(如硼替佐米)在多发性骨髓瘤(MM)的初始治疗中显示出令人满意的临床益处,但耐药性和复发是不可避免的。最近的研究表明,抑制组蛋白脱乙酰基酶(HDACs)可恢复耐硼替佐米的MM的敏感性。因此,我们设计了针对HDAC和蛋白酶体的双重抑制剂,以解决硼替佐米的耐药性。最有效的抑制剂ZY-2和ZY-13对蛋白酶体表现出优异的抑制作用,并对HDAC具有良好的选择性。特别是ZY-2不仅对MM细胞系RPMI-8226,U266和KM3表现出良好的抗增殖活性(IC50值为6.66、4.31和10.1 nM,
