long-term memory

TTK21 is an activator of CBP p300 histone acetyltransferase activity.

CaMKIIα-PHOTAC is a photochemically targeted chimera (PHOTAC) that specifically targets Ca2+ calmodulin-dependent protein kinase II α (CaMKIIα), facilitating its ubiquitination and subsequent proteasome-mediated degradation when exposed to specific light wavelengths. Under illumination, CaMKIIα-PHOTAC diminishes synaptic functions and weakens evoked field excitatory postsynaptic potentials in the mouse hippocampus, impacting physiological responses and sustaining long-term potentiation and memory functions within dendritic domains [1].

(-)-L-threo-PDMP is an enhancer of ganglioside biosynthesis. The (-)-L-threo-PDMP (1S,2S) isomer is the active stimulatory component of DL-threo-PDMP in contrast to (+)-D-threo-PDMP , which is an inhibitor of glucosylceramide synthetase. (-)-L-threo-PDMP upregulates GM3, GD3, and GQ1b synthase levels, which are glycosyltransferases involved in ganglioside biosynthesis, and increases ganglioside levels in cells. It increases neurite outgrowth and synapse formation in vitro and improves retention of a long-term memory learned prior to forebrain ischemia in rats when administered following ischemia at a dose of 40 mg/kg per day.

BGC20-761 is a selective 5-HT6 and dopamine receptor antagonist (human receptor K i values: 5-HT6 (20 nM), 5-HT2A (69 nM), D2 (140 nM)), and a tryptamine analog with a high affinity for 5-HT(6) receptors, that can enhance long-term memory, with potential utility as an antipsychotic agent [1].

MK-0952 is a selective PDE4 inhibitor used to treat long-term memory loss and mild cognitive impairment. It is an intrinsically potent inhibitor and has shown limited whole blood activity.
