stability in aqueous media. 2-Morpholinobenzoic acids were recently identified using vHTS as a potential class of lead compounds, with improvements over D609. In this work 129 analogues in this class were prepared and their PC-PLC inhibitory activity was assessed. It was found that the majority of these novel compounds had improved activity when compared to D609 with the most potent inhibitors completely inhibiting
磷脂酶是参与磷脂的酰基和磷酸酯水解的酶,产生二级信使,这些信使对包括增殖,分化和运动性在内的各种细胞过程都有影响。因此,已经广泛研究了磷脂酶抑制剂作为抗癌治疗剂的用途。磷脂酰胆碱特异性磷脂酶C(PC-PLC)与许多癌细胞系的发展有关,包括侵袭性三阴性乳腺癌。目前在PC-PLC上进行的大多数研究都将D609用作标准抑制剂,但是已知它有多个缺点,包括在水性介质中的稳定性较差。最近使用vHTS将2-Morpholinobenzoic酸鉴定为潜在的先导化合物,与D609相比有所改进。在这项工作中,制备了此类的129个类似物,并评估了其对PC-PLC的抑制活性。发现与最有效抑制剂完全抑制酶活性的D609相比,这些新型化合物大多数具有改善的活性。已确定最佳化合物包含吗啉代和2-取代的N-苄基部分,这些发现通过分子建模得到了解释。本文报道的化合物将有助于改善PC-PLC活性的研究。已确定最佳化合物包含吗
