Biochem/physiol Actions

CRANAD-3, a curcumin analog, is a brain barrier penetrant smart NIRF (near-infrared) probe for both soluble and insoluble Aβ (amyloid beta) species in vivo. CRANAD-3 could be used to monitor the decrease in Aβs after drug treatment in transgenic AD (APP/PS1) mice. CRANAD-3 is suitable for in vivo dually-amplify signal via chemiluminescence resonance energy transfer (DAS-CRET) with ADLumin-1 a brain blood barrier penetrant smart chemiluminescence probe for Aβs

Near-infrared fluorescence (NIRF) molecular imaging has been widely applied to monitoring therapy of cancer and other diseases in preclinical studies; however, this technology has not been applied successfully to monitoring therapy for Alzheimer's disease (AD). Although several NIRF probes for

Abnormal deposition of brain amyloid is a major hallmark of Alzheimer's disease (AD). The toxic extracellular amyloid plaques originating from the aberrant aggregation of beta-amyloid (Aβ) protein are considered to be the major cause of clinical deficits such as memory

Turn-on fluorescence imaging is routinely studied; however, turn-on chemiluminescence has been rarely explored for in vivo imaging. Herein, we report the design and validation of chemiluminescence probe ADLumin-1 as a turn-on probe for amyloid beta (Aβ) species. Two-photon imaging indicates
