 Use of Ac-Tyr-Val-Ala-Asp-aldehyde (pseudo acid)


Ac-YVAD-CHO (L-709049) is a potent, reversible, specific tetrapeptide interleukin-lβ converting enzyme (ICE) inhibitor with mouse and human Ki values of 3.0 and 0.76 nM. Ac-YVAD-CHO can suppress the production of mature IL-lβ[1].

In Vitro Ac-YVAD-CHO inhibits IL-1β in a dose-dependent manner, with mouse and human IC50 values of 2.5 and 0.7 μM. Ac-YVAD-CHO (0.01~100 μM) reduces the elevations of IL-lβ in the plasma and peritoneal fluid treated with LPS in a dose-related manner[1].
In Vivo Ac-YVAD-CHO (10 mg/kg; i.p.; 1 hour) is absorbed from the peritoneal cavity, as well as cleared from the blood rapidly[1]. Ac-YVAD-CHO (50 mg/kg; i.p.; 1 hour) drops precipitously to approximately 1 and 0.2 μM at 30 and 60 minutes after injection[1]. Ac-YVAD-CHO (30 mg/kg; i.p.; 6 hours) suppresses IL-1β levels[1]. Animal Model: CD1 female mice Dosage: 10 mg/kg (Pharmacokinetic Analysis) Administration: I.p.; 1 hour Result: Absorbed from the peritoneal cavity, as well as cleared from the blood rapidly. Animal Model: CD1 female mice Dosage: 50 mg/kg (Pharmacokinetic Analysis) Administration: I.p.; 1 hour Result: Dropped precipitously to approximately 1 and 0.2 μM at 30 and 60 minutes after injection. Animal Model: P. acnes-sensitized mice Dosage: 30 mg/kg Administration: I.p.; 6 hours Result: Suppressed IL-1β levels.
