CA77.1 is a potent, brain-penetrant and orally active chaperone-mediated autophagy (CMA) activator with favorable pharmacokinetics. CA77.1 is a derivative of AR7 (HY-101106) and can increase the expression of the lysosomal receptor LAMP2A in?lysosomes. CA77.1 improves behavior and neuropathology in PS19 mice model and can be used for alzheimer's?disease research.

    Description

    CA77.1 is a potent, brain-penetrant and orally active chaperone-mediated autophagy (CMA) activator with favorable pharmacokinetics. CA77.1 is a derivative of AR7 (HY-101106) and can increase the expression of the lysosomal receptor LAMP2A in?lysosomes. CA77.1 improves behavior and neuropathology in PS19 mice model and can be used for alzheimer's?disease research[1].

    In Vitro

    CA77.1 (0-30 μM; 16 hours) activates CMA in a dose-and time-dependent manner to NIH 3T3 cells stably expressing the KFERQ-PS-Dendra reporter. The CMA activity is quantified as the average of fluorescent puncta per cell[1].
    CA77.1 (20 μM; 6 hours) does not alter on LC3-II expression, and does not effects autophagic flux in NIH 3T3 cells[1].

    In Vivo

    CA77.1 (oral gavage; 10 mg/kg;single dose) demonstrates brain penetrance with favorable pharmacokinetics. The Cmax, AUClast, Tmax and T1/2 are 3534 ng/g, 8338 h*ng/g, 1 hour and 1.89 hour, respectively[1].
    CA77.1 (oral gavage; 30 mg/kg; 6 months) normalizes the previously described locomotor hyperactivity of PS19 mice to control levels. And it reduces the levels and number of neurons containing pathogenic tau conformations in the hippocampus, amygdala, and piriform cortex. And the higher number of microglial cells and presence of large Iba1-positive cells with rod-like dystrophic morphology in vehicle-treated PS19 mice are reduced upon CA77.1 treatment[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
