Avagacestat (BMS-708163) Usage And Synthesis

Uses

Avagacestat acts as a γ-secretase inhibitor allowing for treatment of ALzheimer’s disease. On addition it has seen uses targeting embryonic signaling pathways, which control stem cell and cellular development process in cancer therapy.

Definition

ChEBI: Avagacestat is an oxadiazole and a ring assembly.

Biological Activity

bms-708163 is a potent selective and orally bioavailable inhibitor of γ-secretase with ic50 value of 0.3nm [1].the cleavage of amyloid precusor protein app by γ-secretase causes the production of aβ40 and aβ42, which are cytotoxic and cause ad. in vitro assay shows bms-708163 inhibits the formation of aβ40 and aβ42 in h4-8sw cells. it also inhibits the human recombinant cyps in vitro with ic50 value of 20μm. notch receptor is another substrate of γ-secretase. the inhibition of notch signal pathway results in some side effects. it is shown that the activity of bms-708163 to inhibit notch is 190-fold weaker than to app. in female rats, oral administration of bms-708163 significantly reduces the production of aβ in plasma and brain at 10mg/kg and 100mg/kg. in addition, bms-708163 also reduces aβ in brain and csf in male beagle dogs [1].
