Biological Activity

Description NGP 555 is a small-molecule modulator of γ-secretase and has been successful in achieving good oral absorption, brain penetration, CNS activity, and specificity for a lipid-based membrane target preclinically.
Targets
γ secretase [1]
(Cell-free assay)
In vivo NGP 555 has very good brain penetration/absorption, distribution, metabolism, and excretion (ADME) properties. It efficiently crosses the blood-brain barrier, has a brain:plasma ratio of 0.93 (in Tg2576 mice) and shows in vivo efficacy for lowering the biomarker Aβ42 in rodent studies for brain and plasma. Chronic administration of NGP 555 (milled into chow) to Tg2576 mice results in a significant reduction of amyloid plaques[1].

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    SH-SY5Y-APP cells

  • Concentrations

    10 nM-100 μM

  • Incubation Time

    18 h

  • Method

    SH-SY5Y-APP cells are treated with various concentrations of NGP 555 or NGP 328, in triplicate wells, for 18 hours. Media is collected and analyzed for Aβ peptides using Meso Scale triplex ELISA (Aβ38, Aβ40, and Aβ42) and total Aβ ELISA.
Animal Study:

[1]
  • Animal Models

    Sprague-Dawley male rats

  • Dosages

    0-37.5 mg/kg

  • Administration

    oral administration
