Q134R, a neuroprotective hydroxyquinoline derivative that suppresses nuclear factor of activated T cell (NFAT) signaling. Q134R can across blood-brain barrier. Q134R has the potential for Alzheimer’s disease (AD) and aging-related disorders research[1]. Q134R (1-10 μM) suppresses NFAT signaling, without inhibiting calcineurin activity. Q134R partially inhibits NFAT activity in primary rat astrocytes, but does not prevent calcineurin-mediated dephosphorylation of a non-NFAT target, either in vivo, or in vitro[1]. Q134R (4 mg kg; orally gavage; twice per day; for 7 days) treatment improves cognitive function in rodent models of AD‐like pathology[1]. [1]. Pradoldej Sompol, et al.
