Description

SIB-1553A is an orally bioavailable nicotinic acetylcholine receptors (nAChRs) agonist, with selectivity for β4 subunit-containing nAChRs. SIB-1553A is also a selective neuronal nAChR ligand. SIB-1553A is a cognitive enhancer, and has therapeutic potential for the symptomatic treatment of Alzheimer’s disease and other cognitive disorders[1][2].

In Vitro

SIB-1553A displaces the binding of [H]nicotine (NIC) to the rat brain nAChRs with an IC50 value of 110 nM[1].
In calcium flux assays, SIB-1553A (0.1-5 μM), shows a greater selectivity for beta4-subunit containing recombinant hnAChRs (alpha2beta4, alpha3beta4 and alpha4beta4) vs. beta2-subunit containing nAChRs (alpha4beta2 and alpha3beta2) both in terms of efficacy and potency[2].

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.
