The azatryptophan-based fluorescent platform for in vitro rapid screening of inhibitors disrupting IKKβ-NEMO interaction
摘要:
The nuclear factor-kappa B (NF-kappa B) plays an important role in inflammatory and immune responses. Aberrant NF-kappa B signaling is implicated in multiple disorders, including cancer. Targeting the regulatory scaffold subunit I kappa B kinase gamma (IKK gamma/NEMO) as therapeutic interventions could be promising due to its specific involvement in canonical NF-kappa B activation without interfering with non-canonical signaling. In this study, the use of unnatural amino acid substituted IKK beta with unique photophysical activity to sense water environment changes upon interaction with NEMO provides a powerful in vitro screening platform that would greatly facilitate the identification of compounds having the potential to disrupt IKK beta-NEMO interaction, and thus specifically modulate the canonical NF-kappa B pathway. We then utilized a competitive binding platform to screen the binding ability of a number of potential molecules being synthesized. Our results suggest that a lead compound (-)-PDC-099 is a potent agent with ascertained potency to disrupt IKK beta-NEMO complex for modulating NF-kappa B canonical pathway.

on a “folded π” formula, 12 compounds with two or three folding π planes were designed and synthesized. We found that folded π molecules tend to form well-aligned 1D molecular columns of patterns (“box”, “braid”, or “stair”) with high packing energy, which is mainly contributed by numerous weak π interactions. As a result of effective suppression of molecular motion, all the compounds show very high
