YO-01027 (Dibenzazepine;DBZ) is a potent γ-secretase inhibitor with IC₅₀ values of 2.92 and 2.64 nM for Notch and APPL cleavage, respectively.

IC50: 2.92±0.22 (Notch), 2.64±0.30 (APPL) nM^[1]

Increasing concentrations of DBZ 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]. The molecular targets of CE and DBZ are the N-terminal fragment of presenilin 1 within the γ-secretase complex^[2].

DBZ blocks activated Notch1 signaling in abdominal aortic aneurysm (AAA) tissue from both Ang II-infused Apo E^-/- mice and human undergoing AAA repair. DBZ markedly prevents Ang II-stimulated accumulation of macrophages and CD4+ T cells, and ERK-mediated angiogenesis, simultaneously reverses Th2 response, in vivo^[3]. Administration of DBZ markedly attenuates renal fibrosis and expression of fibrotic markers, including collagen 1α1/3α1, fibronectin, and α-smoothmuscle actin. DBZ significantly inhibits ureteral obstruction -induced expression of transforming growth factor (TGF)- β, phosphorylated Smad 2, and Smad 3^[4].

DBZ (0.1, 1, 2.5, 5, 7.5, 10, 25, 50, 100, 250 nM) are added to the S2 cell medium upon induction of Notch or APPL expression, 6 h before protein harvesting. For each sample, the same inhibitor is also included at the corresponding concentration in the lysis buffer for protein extraction and immunoblot analysis^[1].

Mice: Male wild-type (WT) C57BL/6J and Apo E^-/- mice are used in the study. Ang II-treated mice are received an intraperitoneal injection of either saline vehicle or γ-secretase inhibitor, dibenzazepine (DBZ) (1 mg/kg/d, dissolved in saline) 1 day before mini-pump implantation, and the treatment continued daily for 4 weeks. The blood pressure is measured in conscious mice using a computerized tail-cuff system. All mice are anesthetized. The aortic tissues are removed and prepared for further histological and molecular analysis^[3].
