NZ-66
NZ-66 is a ULK1-Recruiting Chimera (ULKREC) and heterobifunctional chimeric molecule composed of a BL-918-derived ULK1 agonist linked to a mitochondrial outer membrane-targeting TSPO ligand via a six-carbon hexane linker. NZ-66 is a mitophagy inducer recruits ULK1 to mitochondria to induce ULK1-dependent mitophagy, enhanced by mitochondrial insult, independently of the PRKN/PINK axis. NZ-66 can be used for the research of parkinson’s disease.

In Vitro
NZ-66 exhibits ULK1 agonist activity comparable to that of BL-918 (HY-124729 ) in cell-free in vitro kinase assays[1].
NZ-66 (1 μM; 18 h) retains ULK1 agonist activity and induces functional autophagy in PANC-1 cells, as evidenced by increased phosphorylation level of ULK1, altered LC3 processing, decreased p62 level, and enhanced formation of autophagosomes/autolysosomes[1].
NZ-66 (1 μM; 18 h) recruits ULK1 to the outer mitochondrial membrane in PANC-1 cells. This process depends on free TSPO receptors and is enhanced by CCCP-induced mitochondrial damage[1].
NZ-66 (1.25-10 μM; 1-18 h) induces mitophagy in SH-SY5Y cells in a TSPO-dependent manner, and its activity is enhanced by mitochondrial damage without relying on mitochondrial membrane depolarization[1].
NZ-66 (1 μM; 18 h)-induced mitophagy depends on the activity of ULK1/2, which is evidenced by the absence of Mfn2 degradation and the lack of LC3-mitochondria colocalization in ULK1/2 double-knockout mouse embryonic fibroblasts (ULK1/2 DKO MEFs)[1].
NZ-66 (1 μM; 18 h) induces mitophagy in fibroblasts from Parkinson's disease patients with PINK gene knockout, and this process is independent of the PINK1/PARKIN pathway; this is evidenced by the degradation of Mfn2 without activation of phosphorylated ubiquitin (Ser65) and the colocalization of ULK1 with mitochondria[1].

Cell Line:PANC-1 human pancreatic ductal adenocarcinoma cells
-
Concentration:1 μM
-
Incubation Time:18 h
-
Result:Induced a strong increase in phospho-ULK1 (Ser317) levels.
Increased the LC3I:LC3II ratio and caused significant reductions in p62/SQSTM1 levels.
Caused statistically significant 1.3-fold increase in mCherry puncta (autolysosomes) and increases in EGFP puncta (autophagosomes).
Showed that the increase in mCherry puncta was reversed by co-treatment with bafilomycin A1, confirming intact autophagic flux.

Result:Increased colocalisation of ULK1 with TOM20.
Enhanced ULK1-TOM20 colocalisation upon co-treatment with CCCP.
Showed that co-treatment with excess free TSPO ligand prevented ULK1-TOM20 colocalisation.

Mitophagy Solutions
Mitophagy is the selective autophagic degradation of mitochondria and functions as a mitochondrial quality-control pathway that removes damaged, depolarized, excess, or developmentally programmed mitochondria. The pathway links mitochondrial damage recognition, autophagosome recruitment, lysosomal delivery, and mitochondrial turnover to phenotypes such as mitochondrial homeostasis, oxidative-stress control, metabolic remodeling, differentiation, and neurodegeneration-related mitochondrial fidelity. The best-characterized damage-induced pathway is the PINK1-Parkin axis. Parkin is recruited selectively to impaired mitochondria and promotes their autophagic elimination, while mitochondrial depolarization stabilizes PINK1 on damaged mitochondria, recruits Parkin, and activates Parkin-dependent mitophagy. PINK1 also phosphorylates ubiquitin to activate Parkin E3 ubiquitin ligase activity, and PINK1-driven ubiquitin phosphorylation creates a feed-forward signal for recruiting autophagy machi
