来那度胺是一种主要通过在抗血管生成中表达而具有抗肿瘤活性的免疫调节剂。为了增强来那度胺的药理活性,设计了一系列来那度胺衍生物作为肿瘤血管生成抑制剂。使用反向对接方法在Auto-Dock 4.0上虚拟筛选来那度胺衍生物的潜在抗血管生成靶标。选择血管内皮生长因子受体,表皮生长因子受体,成纤维细胞生长因子受体,BCR-ABL酪氨酸激酶,p38丝裂原活化蛋白激酶和金属蛋白激酶这六个靶蛋白作为靶标。来那度胺衍生物是通过烷基化,酰化或磺酰化来那度胺合成的,并通过1 H NMR验证,13C NMR和LC-MS。通过在食管癌细胞系EC9706中使用CCK-8检测其抗癌活性。结果表明来那度胺衍生物的抑制活性高于来那度胺。

The present invention provides a means to modulate gene expression in vivo in a manner that avoids problems associated with CRISPR endogenous protein knock-out or knock-in strategies and strategies that provide for correction, or alteration, of single nucleotides. The invention includes inserting into the genome a nucleotide encoding a heterobifunctional compound targeting protein (dTAG) in-frame with the nucleotide sequence of a gene encoding an endogenously expressed protein of interest which, upon expression, produces an endogenous protein-dTAG hybrid protein. This allows for targeted protein degradation of the dTAG and the fused endogenous protein using a heterobifunctional compound.
