Recent studies revealed that MALT1 is a promising therapeutic target for the treatment of ABC-DLBCL. Among several reported MALT1 inhibitors, MI-2 as an irreversible inhibitor represents a new class of ABC-DLBCL therapeutics. Due to its inherent potential cross-reactivity, further structure–activity relationship (SAR) study is imperative. In this work, five focused compound libraries based on the chemical
最近的研究表明,MALT1是ABC-DLBCL的有希望的治疗靶标。在几种报道的MALT1抑制剂中,作为不可逆抑制剂的MI-2代表了一类新的ABC-DLBCL治疗剂。由于其固有的潜在交叉反应性,必须进行进一步的结构-活性关系(SAR)研究。在这项工作中,基于MI-2的化学结构,设计并合成了五个重点化合物库。系统的SARs显示2-甲氧基乙氧基的侧链对活性几乎没有影响,可以被其他官能团取代,从而提供具有保留或增强效力的新MI-2类似物。化合物81 – 83带有末端羟基的侧链显示出对MALT1的增强活性。用吡唑代替三唑核心也是可以容忍的,而其他位点的结构修饰是有害的。这些发现将促进小分子MALT1抑制剂的进一步开发。
