Pegsebrenatide
Based on 1 Customer Validation
Pegsebrenatide (NLY01) is a blood-brain barrier-penetrant GLP-1R agonist. Pegsebrenatide alleviates retinal inflammation and neuronal death secondary to ocular hypertension. Pegsebrenatide significantly delays onset and reduces disease severity in experimental autoimmune encephalomyelitis. Pegsebrenatide inhibits the formation of A1 reactive astrocytes in nerve cells and reduces the loss of retinal ganglion cells and dopaminergic neurons. Pegsebrenatide exerts neuroprotective effects in a mouse model of Parkinson's disease by directly preventing microglia-mediated conversion of astrocytes to the A1 neurotoxic phenotype. Pegsebrenatide can be used for research on glaucoma, Parkinson's disease, and multiple sclerosis.

Biological Activity
Pegsebrenatide (2 h) is a potent GLP1R agonist that induces cAMP production in GLP1R-transfected HEK293 cells[4].
Pegsebrenatide (1 μM) inhibits the increased expression levels of pro-inflammatory activation marker genes (Il1a, Il1b, Tnf, C1qa, Il6) and the elevated secretion of pro-inflammatory cytokines (IL-1α, TNFα, C1q) induced by α-syn PFF in mouse primary microglia, blocks α-syn PFF-induced conversion of mouse primary astrocytes to neurotoxic A1 reactive astrocytes, and thereby prevents α-syn PFF-ACM-induced death of mouse primary cortical neurons and dopaminergic neurons[4].

| Species | Dose | Route | T1/2 | Cmax | Tmax | MRT | AUCinf |
|---|---|---|---|---|---|---|---|
| Monkey[4] | 32 μg/kg | s.c. | 88 h | 52.7 ng/mL | 72 h | 114 h | 6833.5 ng·h/mL |
Pegsebrenatide (10 mg/kg; s.c.; twice weekly; 42 days) significantly delays EAE onset, attenuates disease severity, suppresses peripheral and CNS inflammation, and prevents RGC loss in chronic EAE[3].
Pegsebrenatide (NLY01) (3 mg/kg; s.c.; twice weekly; 5 months) exerts robust neuroprotective and behavioral rescue effects in the α-syn PFF mouse model of Parkinson's disease by inhibiting microglial activation and subsequent A1 astrocyte formation[4].
Pegsebrenatide (3 mg/kg; s.c.; twice weekly; until endpoint (10 months of age or death)) significantly extends survival and reduces neuropathological abnormalities in hA53T transgenic mice with familial α-synucleinopathy[4].
