Boc-Leu-Gly-Arg-AMC is a fluorogenic AMC substrate for the convertases. Boc-Leu-Gly-Arg-AMC can be used in enzymatic assays[1][2].
体外研究 (In Vitro)
To demonstrate the presence in the abdominal gland of proteolytic enzymes capable of generating Sodefrin, an enzymatic assay was developed using Boc-Leu-Gly-Arg-AMC as synthetic substrate. A crude extract of the abdominal gland hydrolyzed Boc-Leu-Gly-Arg-AMC to liberate 7-amino-4- methylcoumarin, suggesting that enzymes that generate sodefrin from its precursor molecule are present in the gland. The activity in the extract for cleaving Boc-Leu-Gly-Arg-AMC is optimal at pH 9.0 and 45 ℃[1].

Ac-DEVD-AMC is the caspase-3 substrate and could be used to monitor intracellular caspase-3 activity[1].The AMC moiety is highest at 2 h (area =5.6±1.8), the AMC peak area for Ac-DEVD-AMC incubated without lung specimen (substrate alone) for 6 h is relatively small[2].

Cell Assay [2]
Lung fragments (about 20 mg each) are collected from rats and mice. The samples are incubated at 37°C in 50 mL KH buffer or MEM (continuously gass with 95% O2 : 5% CO2) for up to 6 h. At specific time points, samples are incubated in oxygenated KH buffer or MEM with 32 μM zVAD-fmk or 15 μL DMSO for 20 min (f/v=1.0 mL). Ac-DEVD-AMC (37 μM) is then added and the incubation continues for additional 20 min. At the end of incubation, the tissue is disrupted by vigorous homogenization for 2 min, sonication for 3 min and 10 passages through a 27-G needle. This disruption procedure quenches the Ac-DEVD-AMC cleavage reaction due to dilution. The supernatants are collected by centrifugation (~6,300g for 90 min) through microcentrifuge filter, separateed on HPLC, and analyzed for the fluorogenic AMC moiety[2].
