Usage And Synthesis

Description

Ac-YVAD-CHO is an inhibitor of caspase-1/interleukin-1β converting enzyme (ICE; K_i = 0.76 nM) and an acetylated form of the caspase-1 inhibitor YVAD-CHO . It is selective for caspase-1 over caspase-4, -5, -8, -9, and -10 (K_is = 163-970 nM), as well as over caspase-2, -3, -6, and -7 (K_is = >10,000 nM for all). It inhibits activation of caspase-1 and IL-1β in a cell-free assay using LPS-treated THP-1 cell homogenates when used at a concentration of 5 μM. Ac-YVAD-CHO (12.5 μmol/kg) reduces pancreatic levels of IL-18 and serum levels of IL-1β, as well as reduces pyroptosis of pancreatic cells, in a mouse model of cerulein-induced acute pancreatitis but does not decrease pancreatic expression of NOD-like receptor protein 3 (NLRP3). It increases susceptibility to lethal E. coli infection but prevents LPS-induced death in C3H/HeN mice when administered at doses of 5 and 10 mg/kg, respectively.

Uses

A potent, specific, and reversible inhibitor of caspases-1, -4 and -5

in vivo

Ac-YVAD-CHO (30 mg/kg; i.p.; 6 hours) suppresses IL-1β levels in blood of P. acnes-sensitized mice^[1].
Ac-YVAD-CHO (2-8 μg, intrastriatal infusion) attenuates Quinolinic acid (QA)-induced apoptosis in rat striatum^[2].
Ac-YVAD-CHO (10 and 50 mg/kg; i.p.; 1 hour) is cleared from the blood rapidly, and drops precipitously to approximately 1 and 0.2 μM at 30 and 60 minutes after injection^[1].

Animal Model:	P. acnes-sensitized mice^[1]
Dosage:	50 mg/kg
Administration:	I.p.;
Result:	Suppressed IL-1β levels in blood.

Animal Model:	Quinolinic acid-treated Rats^[2]
Dosage:	2-8 μg
Administration:	Intrastriatal infusion.
Result:	Attenuated Quinolinic acid (QA)-induced increases in p53 and apoptosis in rat striatum. Inhibited QA-induced increases in caspase-1 activity and p53 protein levels, with no effect on QA-induced IκB-α degradation, NF-κB or AP-1 activation.

IC 50

IL-1β; Caspase-1
