PQK7
PQK7 is an α-synuclein (α-synuclein) binder with a Kd value of 4 μM. PQK7 binds to key residues in the NAC region of ⍺-Syn, enhances the fluctuation of ⍺-Syn, reduces β-sheet content, maintains the solubility of ⍺-Syn monomers, and preserves the normal function of the protein. PQK7 reduces the toxicity of ⍺-Syn aggregates, restores cell cycle progression, decreases apoptosis (apoptosis), and inhibits ROS production. PQK7 can be used for the research of Parkinson's disease.

生物活性
PQK7 (2.5-70 μM; 7-32 h) inhibits α-Syn fibril formation, reduces ThT fluorescence by approximately 40% after 30 h, and exhibits sustained inhibitory activity over time, but does not disrupt pre-formed fibrils[1].
PQK7 (2-20 μM; 24 h) reduces β-sheet formation of α-Syn monomers and induces the transition of this protein to a random coil conformation[1].
PQK7 (2.5 μM; 0-48 h) reduces the number and size of α-Syn aggregates[1].
PQK7 (2.5 μM; 12-32 h) maintains α-Syn in a soluble state during the fibrosis process[1].
PQK7 (2.5-70 μM; ~48 h) reduces the seeding activity of α-Syn fibrillation products; additionally, at concentrations of 2.5-30 μM for 30 h, it inhibits preformed fibril-induced secondary α-Syn fibrillation[1].
PQK7 (2 μM; 24 h) reduces the nucleation of α-Syn monomers on preformed α-Syn fibrils[1].
PQK7 (2 μM; 24 h) reduces α-Syn aggregate-induced cytotoxicity in SH-SY5Y cells and restores cell viability after 24 h of treatment[1].
PQK7 (2 μM; 36 h fibril formation, 24 h cell treatment) restores normal cell cycle progression in SH-SY5Y cells treated with 36 h-aged α-Syn fibrils, reverses the decrease in the proportion of G1-phase cells, and reduces the proportion of cells entering the apoptotic sub-G1 phase after 24 h of treatment[1].
PQK7 (2-70 μM; 6 h) reduces intracellular ROS levels induced by α-Syn aggregates in SH-SY5Y cells[1].
PQK7 (2 μM; 36 h fibril formation, 24 h cell treatment) significantly reduces late apoptosis and necrosis induced by α-Syn fibril treatment for 24 h in SH-SY5Y cells, while slightly increasing the level of early apoptosis[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
