BIIB042 is a potent, orally active, brain-penetrant, and selective γ-secretase modulator (GSM). BIIB042 reduces Aβ42 and increases Aβ38 levels in cells. BIIB042 significantly reduces brain Aβ42 levels in CF-1 mice and Fischer rats, as well as plasma Aβ42 levels in cynomolgus monkeys. BIIB042 reduces Aβ42 levels and Aβ plaque burden in Tg2576 mice. BIIB042 can be used for alzheimer's disease (AD) research[1][2].

Description

BIIB042 is a potent, orally active, brain-penetrant, and selective γ-secretase modulator (GSM). BIIB042 reduces Aβ42 and increases Aβ38 levels in cells. BIIB042 significantly reduces brain Aβ42 levels in CF-1 mice and Fischer rats, as well as plasma Aβ42 levels in cynomolgus monkeys. BIIB042 reduces Aβ42 levels and Aβ plaque burden in Tg2576 mice. BIIB042 can be used for alzheimer's disease (AD) research[1][2].

In Vitro

BIIB042 (compound 10a) inhibits COX1 and COX2 very weakly (IC50 = 35 and 27 μM, respectively) and exhibits weak inhibition of the hERG channel (IC50 = 15 μM)[1].
BIIB042 exhibits good cellular permeability and is not a substrate for efflux transporters[1].
BIIB042 demonstrates good metabolic stability in liver microsomes and does not inhibit major cytochrome P450 enzymes[1].
BIIB042 (3-30 μM, 20 h) has no effect on HES-1 protein levels in MC-IXC cells, indicating its selective action on amyloid precursor protein processing without impacting Notch signaling[2].
BIIB042 (20 h) reduces the levels of Aβ42 (IC50 = 64.3 nM), increased the levels of Aβ38 (EC50 = 146 nM) and has little effect on the levels of Aβ40 in H4-APP cells[2].

Incubation Time: 20 h
Result: Did not alter HES1 protein levels.
In Vivo

BIIB042 (0-60 mg/kg, p.o. (in diet), daily for 65 days) significantly increases Aβ38 levels and decreases Aβ42 levels in brain of Tg2576 mice[2].
BIIB042 (0.3-30 mg/kg, p.o. (in diet), daily for 6 months) significantly decreases Aβ42 levels in brain, and reduces parenchymal amyloid plaque burden of Tg2576 mice[2].
BIIB042 (0-100 mg/kg, i.g., single dose) dose-dependently lowers Aβ42 and elevates Aβ38 in the brain and plasma of CF-1 mice, demonstrating a potent and brain-penetrant GSM profile[2].

Showed a trend towards increased Aβ levels at 0.3 and 1 mg/kg.
Animal Model: CF-1 mice[2]
Dosage: 0, 3, 10, 30 and 100 mg/kg

Result: Induced significant and dose-dependent decreases in Aβ42 at all tested doses.
Showed a dose-dependent increases in Aβ38 at 10, 30 and 100 mg/kg.
Induced Aβ pharmacodynamic responses in plasma, with similar effects as in brain with decreases in Aβ42, increases in Aβ38 and small changes in Aβ40 at higher doses.
Brain concentrations were approximately 80% of plasma concentrations at the 4 h time point across all doses.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
