生物活性

PL553 is a specific and high-affinity fluorigenic substrate of Leukotriene A4 hydrolase, with a λmax of 210 nm and λem of 410 nm.

体外研究
(In Vitro)

PL553 is a specific and high-affinity fluorigenic substrate of Leukotriene A4 hydrolase (LTA4H), with a maximum absorption (λmax) of 210 nm and maximum emission (λem) of 410 nm. PL553 is a better LTA4H substrate than (l)-Ala-β-naphthylamide, and resistant to cleavage by other aminopeptidases, but can be cleaved by FAAH. PL553 (40 μM) is used to evaluate the potencies of known inhibitors toward LTA4H[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Kinase Assay
[1]

The ability of PL553 to discriminate LTA4H from APN enzymatic activity is tested using the (l)-Ala-β-naphthylamide and PL553 peptide substrates at 40 μM with either APN from porcine kidney (0.33 mU/mL) or recombinant human LTA4H (0.6 μg/mL). The enzymatic reactions proceeds for 1 h at 37°C in a final volume of 100 μL of 50 mM Tris-HCl (pH 7.4) or 50 mM Tris-HCl (pH 7.4) and 100 mM NaCl for APN or LTA4H, respectively[1].

体外研究
(In Vitro)

Hoechst 34580 prefers to locate near hydrophobic regions with binding affinity with the inhibition constant IC50 of 0.86±0.05 μM for Hoechst 34580. Hoechst 34580 is a good candidate for treating the Alzheimer’s disease by inhibiting Aβ formation. 50 μM Aβ42 solutions co-incubated with 100, 25, 12.5, 3.125, 0.78, and 0.1, 0.01 μM Hoechst 34580 at 37 °C for 70 h. Hoechst 34580 can inhibit the aggregation of Aβ42 in a dose-dependent manner. And the half-maximal concentration (IC50) is examined. The IC50 is obtained by measuring the concentration of Hoechst 34580 while maintaining the Aβ42 concentration which gave 0.86±0.05 μM for Hoechst 34580[1].
