制备方法与用途

生物活性

PROTAC RAR Degrader-1 包含 cIAP1 配体结合基团、linker 和 RAR 配体结合基团。在 HT1080 细胞中，PROTAC RAR Degrader-1 降低 RAR 水平，在 30 μM 浓度时达到最大降解程度。同样地，基于 cIAP1 的降解剂也被称为 SNIPER。

  Design, synthesis and biological evaluation of nuclear receptor-degradation inducers

  摘要：

  Compounds that regulate the function(s) of nuclear receptors (NRs) are useful for biological studies and as candidate therapeutic agents. Most such compounds are agonists or antagonists. On the other hand, we have developed specific protein degradation inducers, which we designated as SNIPERs (Specific and Nongenetic IAPs-dependent Protein ERasers), for selective degradation of target proteins. SNIPERs are hybrid molecules consisting of an appropriate ligand for the protein of interest, coupled to a ligand for inhibitor of apoptosis proteins (IAPs), which target the bound protein for polyubiquitination and proteasomal degradation. We considered that protein knockdown with SNIPERs would be a promising alternative approach for modulating NR function. In this study, we designed and synthesized degradation inducers targeting retinoic acid receptor (RAR), estrogen receptor (ER), and androgen receptor (AR). These newly synthesized RAR, ER, and AR SNIPERs, 9, 11, and 13, respectively, were confirmed to significantly reduce the levels of the corresponding NRs in live cells. (C) 2011 Elsevier Ltd.

  Compounds that regulate the function(s) of nuclear receptors (NRs) are useful for biological studies and as candidate therapeutic agents. Most such compounds are agonists or antagonists. On the other hand, we have developed specific protein degradation inducers, which we designated as SNIPERs (Specific and Nongenetic IAPs-dependent Protein ERasers), for selective degradation of target proteins. SNIPERs are hybrid molecules consisting of an appropriate ligand for the protein of interest, coupled to a ligand for inhibitor of apoptosis proteins (IAPs), which target the bound protein for polyubiquitination and proteasomal degradation. We considered that protein knockdown with SNIPERs would be a promising alternative approach for modulating NR function. In this study, we designed and synthesized degradation inducers targeting retinoic acid receptor (RAR), estrogen receptor (ER), and androgen receptor (AR). These newly synthesized RAR, ER, and AR SNIPERs, 9, 11, and 13, respectively, were confirmed to significantly reduce the levels of the corresponding NRs in live cells. (C) 2011 Elsevier Ltd.
