Application

Deshydroxy LY-411575 has been used in dibenzazepine (DBZ) treatment and chemical treatment.

Biochem/physiol Actions

Deshydroxy LY-411575 is a cell-permeable γ-secretase inhibitor and inhibtor of Notch processing. Deshydroxy LY-411575 significantly lowers both brain and plasma Aβ40 levels by ~72% in Tg2576 mutant APP transgenic mouse model and potently blocks Notch processing, with an IC50 of 1.7 nM in SupT1 cells.
LY411575 prevents SPP (signal peptide peptidase) dependent cleavage of HCV (hepatitis C virus) core protein.

Development (Cambridge, England), 149(10) (2022-05-04)
The earliest hematopoietic stem and progenitor cells (HSPCs) are generated from the ventral wall of the dorsal aorta, through endothelial-to-hematopoietic transition during vertebrate embryogenesis. Notch signaling is crucial for HSPC generation across vertebrates; however, the precise control of Notch during

During development, hematopoietic stem cells (HSCs) undergo a rapid expansion in the fetal liver (FL) after their emergence in the aorta-gonad-mesonephros (AGM) region. We recently reported that the endolysosomal trafficking factor BLOS2, encoded by the Bloc1s2 gene, regulates HSC/hematopoietic progenitor

Expansion of pulmonary neuroendocrine cells (PNECs) is a pathological feature of many human lung diseases. Human PNECs are inherently difficult to study due to their rarity (<1% of total lung cells) and a lack of established protocols for their isolation.
