Biological Activity

Description

DBZ (Dibenzazepine) is a dipeptidic γ-secretase inhibitor with IC50 of 2.6 nM and 2.9 nM in cell-free assays for APPL and Notch cleavage, respectively.

Targets

γ secretase ^[1] (Cell-free assay)	Notch ^[1] (Cell-free assay)
2.6 nM	2.9 nM

In vitro
In vitro	YO-01027 interacts directly with theγ-secretase complex and targets the N-terminal Presenilin fragment. Increasing concentrations of YO-01027 administered to APPL- or Notch-expressing cells leads to the progressive accumulation of APPL CTF fragments and a decrease in NICD production in a strictly dose-dependent manner. ^[1] 10 μM of YO-01027 reduces breast cancer stem cells (BCSC) number and activity. ^[2] A recent research indicates YO-01027 impairs mucin protein MUC16 biosynthesis in a concentration-dependent manner in undifferentiated cells at both preconfluent and confluent stages through Notch inhibition, but not in postmitotic stratified cells. ^[3]
Kinase Assay	Pharmacological Inhibition of γ-secretase Activity
Kinase Assay	For YO-01027, pilot experiments are performed with different drug concentrations ranging from 0.1 nM to 250 nM to determine the effective linear range and maximal inhibition dose for YO-01027. YO-01027 is added at the required concentrations to the S2 cell medium upon induction of Notch or APPL expression, 6 hours before protein harvesting. For each sample, YO-01027 is also included at the corresponding concentration in the lysis buffer for protein extraction and immunoblot analysis.
Cell Research	Cell lines	BCSC
	Concentrations	10 μM
	Incubation Time	3 days
	Method	Cells are resuspended at ≤1 × 10⁶ in 100 μL sorting buffer (PBS containing 0.5% bovine serum albumin, 2 mM EDTA) and incubated with preconjugated primary antibodies BEREP4-FITC (1:10), CD44-APC (1:20), and CD24-PE (1:10) for 10 minutes at 4 °C. The cells are washed in PBS and centrifuged at 800 × g for 2 minutes. For analysis, cells are resuspended in 500 μL of sorting buffer and fluorescence is measured using FACSCalibur and analyzed using WinMIDI 2.8. For sorting, cells are resuspended in 1× HBSS after incubation with the primary antibodies. Cells are sorted, with HBSS as sheath fluid, at 16 p.s.i. using FACSAria. The CD24_low cell population gated by FACS is the lowest quintile of CD24-positive cells plus all the CD24-negative cells.

In Vivo
In vivo	YO-01027, which is delivered 1 mg/mL by i.p. injection on the day of cell injection and every subsequent 3 days, YO-01027 significantly, decreases MCF7 but not MDA-MB-231 tumors and increases latency compared with control mice (18-28 days). YO-01027-treated MCF7 tumors that did form had significantly reduced tumor volumes. ^[2] Treatment of YO-01027 into C57BL/6 mice inhibits epithelial cell proliferation and induces goblet cell differentiation in intestinal adenomas in a dose-dependent manner. ^[4]
Animal Research	Animal Models	C57BL/6 mice
	Dosages	0, 3, 10, 30 μmol/kg
	Administration	Injected daily intraperitoneally
