Small-Molecule Activator of UNC-51-Like Kinase 1 (ULK1) That Induces Cytoprotective Autophagy for Parkinson’s Disease Treatment
摘要:
UNC-51-like kinase 1 (ULK1), the yeast Atg1 ortholog, is the sole serine-threonine kinase and initiating 1, enzyme in autophagy, which may be regarded as a target in Parkinson's disease (PD). Herein, we discovered a small molecule 33i (BL-918) as a potent activator of ULK1 by structure-based drug design. Subsequently, some key amino acid residues (Arg18, Lys50, Asn86, and Tyr89) were found to be crucial to the binding pocket between ULK1 and 33i by site-directed mutagenesis. Moreover, we found that 33i induced autophagy via the ULK complex in SH-SYSY cells. Intriguingly, this activator displayed a cytoprotective effect on MPP+-treated SH-SYSY cells, as well as protected against MPTP-induced motor dysfunction and loss of dopaminergic neurons by targeting ULK1-modulated autophagy in mouse models of PD. Together, these results demonstrate the therapeutic potential to target ULK1, and 33i, the novel activator of ULK1, may serve as a candidate drug for future PD treatment.

A series of diamidederivatives containing α-amino acids were designed and synthesized. These compounds were evaluated for their insecticidalactivities against Plutella xylostella, Mythimna separate, Myzus persicae, and Tetranychus cinnabarinus. Most of the title compounds containing an l-phenylglycine skeleton were endowed with good activities at the concentration of 500 mg·L−1. Compounds (R)-A6
