InSolution g-Secretase <strong>Inhibitor</strong><br />
XIX<br />
565787 {(2S,3R)-3-(3,4-Difluorophenyl)-2-(4-fluorophenyl)-4-hydroxy-N-<br />
((3S)-2-oxo-5-phenyl-2,3-dihydro-1H-benzo[e][1,4]diazepin-3-yl)butyramide}<br />
Supplied as a 5 mM ( 00 mg/37 ml) solution in DMSO. A cell-permeable,<br />
highly potent g-secretase inhibitor (IC 50 = 60 pM towards Ab 40<br />
secretion in SH-SY5Y cells overexpressing spbA4CTF).<br />
N g-Secretase <strong>Inhibitor</strong> XX 565789 A cell-permeable, potent g-secretase inhibitor. Significantly lowers<br />
both the brain and plasma Ab 40 levels by ~72% in Tg2576 mutant APP<br />
transgenic mouse model ( 00 mM/kg, b.i.d.). Also potently inhibits<br />
Notch processing (IC 50 = .7 nM in SupT cells), and induces conversion<br />
of proliferative crypt cells into post-mitotic goblet cells in both<br />
C57BL/6 and APC Min mouse model ( 0 mM/kg, i.p.).<br />
N g-Secretase <strong>Inhibitor</strong> XXI 565790 A cell-permeable, potent, and selective peptidomimetic and nontransition-state<br />
analog inhibitor of g-secretase and Notch processing<br />
(IC 50 = 300 pM for Ab 40 in CHO cells overexpressing wild type bAPP;<br />
240 pM for Ab 40 , 370 pM Ab 42 and 320 pM for NICD, respectively, in<br />
HEK293 cells stably transfected with bAPP 695 and mNotchDE(M 727V);<br />
00 pM for both Ab 40 and Ab 42 in SH-SY5Y cells stably transfected<br />
with SPA4CT). Also lowers Ab levels in several APP transgenic mouse<br />
model. Reported to bind to presenilins and suppress the proteolytic<br />
ability to cleave several transmembrane protein substrates, including<br />
APLP and APLP2, CD44, ErbB4, E-cadherin, low density lipoprotein<br />
receptor-related proteins, Notch ligands, and p75 NTR . Yet, at higher<br />
concentrations (200-400 mM) only weakly affects presenilin activity.<br />

g -Secretase <strong>Inhibitor</strong> I 40 565765 [N-trans-3,5-Dimethoxycinnamoyl)-Ile-leucinal; t-3,5-DMC-IL-CHO]<br />
A potent, cell-permeable, reversible inhibitor of g-secretase that<br />
preferentially inhibits the secretion of Ab (>90%) vs. Ab (~ 5%).<br />
-40 -42<br />
IC = ~ 5 mM for Ab , ~22 mM for Ab , and >50 mM for Ab in<br />
50 total -40 -42<br />
CHO cells stably transfected with cDNA encoding bAPP695. Reported<br />
to be be about 0-fold more potent than Z-Val-Phe-CHO (MDL 28 70;<br />
Cat. No. 208722).<br />
g -Secretase <strong>Inhibitor</strong> II 40 565766 (N-tert-Butyloxycarbonyl-Gly-Val-Valinal)<br />
A cell-permeable, substrate-based (g -site) g-secretase inhibitor that<br />
40<br />
is reported to preferentially (> 90%) inhibit Ab cleavage at site 40 vs.<br />
42, in a dose-dependent fashion, in transiently transfected 293T cells<br />
over-expressing APP695NL.<br />

InnoZyme TACE Activity Kit<br />
The InnoZyme TACE Activity Kit is a specific and sensitive assay kit<br />
designed to measure human TACE activity in cell lysates and biological<br />
samples and for screening enzyme inhibitors. An anti-human TACE<br />
monoclonal antibody pre-coated on a 96-well plate captures human<br />
TACE. The activity of captured TACE is measured using an internally<br />
quenched fluorescent substrate, MCA-KPLGL-Dpa-AR-NH 2 . Cleavage<br />
of the scissile amide bond, G-L, releases the fluorophore from the<br />
quenching molecule, Dpa, resulting in an increase in fluorescence.<br />
The level of fluorescence is directly related to the enzyme activity.<br />
