Lycoramine hydrobromide
Lycoramine hydrobromide is a blood-brain barrier-penetrating Acetylcholinesterase inhibitor and Galanthamine (HY-76299) derivative. Lycoramine hydrobromide induces Amyloid-beta plaque clearance. Lycoramine hydrobromide induces reversal of cognitive decline and memory improvement. Lycoramine hydrobromide can be used for research on Alzheimer's disease and myasthenia gravis.

In Vitro
Lycoramine hydrobromide produces weaker AChE inhibition than Galanthamine (HY-76299) in the HPLC-IMER-MS bioanalytical system[1].
Lycoramine hydrobromide exhibits 42% higher acetylcholinesterase inhibitory activity than galantamine under in vitro conditions[3].

Result:Decreased escape latency in the acquisition phase of the Morris water maze test.
Increased time spent in the target quadrant during the probe phase.
Detected in all dissected brain regions (cortex, cerebellum, hippocampus, and remaining regions), confirming blood-brain barrier passage.
Caused a dramatic decrease in Aβ load, greater than galantamine.
Identified 2556 proteins in the cortex, with 145 proteins showing significant changes (fold change ≥ 1.3; q < 0.05).
Decreased cortical protein levels of clusterin (fc = 0.71, q = 0.00), apolipoprotein E (fc = 0.74, q = 0.009), microtubule-associated protein tau (fc = 0.49, q < 0.000), MAP1A (fc = 0.69, q < 0.000), MAP2 (fc = 0.44, q < 0.000), α-synuclein (fc = 0.49, q < 0.000), Tppp/25 (fc = 0.63, q < 0.000), GFAP (fc = 0.69, q = 0.004), Gja-1 (fc = 0.6, q = 0.007), AK-1 (fc = 0.67, q = 0.002), EHD3 (fc = 0.75, q = 0.019), and Synaptotagmin-5 (fc = 0.44, q = 0.006).
Increased cortical protein levels of GABRB2 (fc = 1.3, q = 0.011), Neurobeachin (fc = 1.3, q = 0.006), heat shock 70 kDa protein 1-like (fc = 1.35, q < 0.000), AT2B4/PMCA4 (fc = 1.81, q = 0.001), OSBP-1 (fc = 1.37, q = 0.018), and SRBS-1 (fc = 1.9, q = 0.004).
Increased cortical protein levels of Vimentin (fc = 1.43) and Gap junction alpha-1 protein (fc = 1.68).
