Arg-PEG1-Tαsyn

Arg-PEG1-Tαsyn is an α-syn PROTAC degrader with a DC₅₀ of 0.28 μM in U251 cells. Arg-PEG1-Tαsyn employs the amino acid arginine (Arg) as the E3 ligase UBR1 ligand and a benzothiazole-aniline variant as the warhead for α-syn. Arg-PEG1-Tαsyn significantly reduces α-syn aggregates and improves the dopaminergic neuronal impairment and the locomotion with safety profile in vivo.Arg-PEG1-Tαsyn shows the high degradation effect in mammalian cells for both wild-type α-syn and the α-syn (A53T) mutant. Arg-PEG1-Tαsyn can be used for Parkinson’s disease research.

In Vitro

Arg-PEG1-Tα-syn (0-10 μM, 48 h) significantly promotes the reduction of α-syn^A53T in U251 cells with a DC₅₀ of 0.28 μM, and a D_max of 90.5% at 5 μM^[1].
Arg-PEG1-Tα-syn (1 μM,0-72 h) time-dependently exerts α-syn^A53T degradation in U251/α-syn^A53T cells^[1].
Arg-PEG1-Tα-syn (1 μM, 48 h) exhibits consistent degradation effects on α-syn in U251/α-syn^WT, U251/α-syn^A53T, 293/α-syn^WT, 293/α-syn^A53T, SH-SY5Y/α-syn^WT and SH-SY5Y/α-syn^A53T cells^[1].
Arg-PEG1-Tα-syn induces α-syn^A53T reduction, an effect that is reversed by MG132 (HY-13259) but not by Chloroquine (HY-17589A)^[1].
Arg-PEG1-Tα-syn (1 μM, 48 h) mediates the regulation of α-syn^WT andα-syn^A53T via the E3 ubiquitin ligase UBR1 in U251 (knocked down UBR1, UBR2, UBR4, and UBR5 separately using shRNA) cells^[1].
Arg-PEG1-Tα-syn (0-5 μM, 48 h) protects cells from the toxicity induced by α-syn WT or α-syn A53T overexpression in SH-SY5Y cells (overexpressing α-syn^WT or α-syn^A53T) by reducing α-syn^A53T aggregation^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Arg-PEG1-Tα-syn (mixed with OP50 bacteria at varying concentrations for feeding, p.o., from the L1 larval stage to day-5 adulthood) decreases α-syn aggregates, significantly improves the morphology of neuronal cell bodies and synapses and partially restore the dopaminergic neuronal functional deficits induced by α-syn pathology in C. elegans NL5901^[1].
Arg-PEG1-Tα-syn (0-10 μM were mixed with OP50 bacteria for feeding, p.o., from the L1 larval stage to day-5 adulthood) effectively ameliorates locomotor dysfunction induced by α-syn pathology in a dose-dependent manner in C. elegans overexpressing human α-syn A53T. with safety profile (5 μM) in C. elegans UM0020 and C. elegans (W.T.) ^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
