PBA-1105 TFA
PBA-1105 TFA is an autophagy-targeting chimera (AUTOTAC) that induces p62 self-oligomerization. PBA-1105 TFA selectively binds to exposed hydrophobic regions of misfolded proteins, facilitating their degradation via the autophagic pathway. PBA-1105 TFA increases the autophagic flux of Ub-conjugated aggregates.

Description
In Vitro
PBA-1105 TFA induces autophagic degradation of stably expressed mutant tau at DC50 of 0.71 nM and Dmax,24 hr of 100 nM, followed by a hook effect at higher concentrations[1].
PBA-1105 (0.1-10 μM; 24 hours) TFA induces the autophagic degradation of misfolded proteins and aggregates at nanomolar concentrations. PBA-1105 TFA leads to significant degradation of mutant tau and misfolded proteins[1].

-
Animal Model:hTauP301L-BiFC transgenic mice[1]
-
Dosage:20 mg/kg or 50 mg/kg (PBS containing 30% polyethylene glycol (PEG))
-
Administration:Intraperitoneal injection; three times per week; for 4 weeks
-
Result:Effectively cleared tau aggregates in a dose-dependent manner, significantly reducing insoluble tau species in the brain while leaving soluble tau species unaffected.
Resulted in increased levels of autophagic markers like LC3, confirming the activation of autophagic degradation pathways.
Immunohistochemical analysis showed a marked reduction in tau oligomers and phosphorylated tau in both cortical and hippocampal regions.
