Background

ST101 is an azaindolizinone derivative that likely has diverse effects. It has been shown to induce APP cleavage at a novel site novel site, generating a 17 kDa C-terminal fragment. This cleavage event precludes  Aβ generation (Green et al., 2011). ST101 has also been shown to activate a number of intracellular signaling pathways such as ERK1/2 following stimulation with dopamine D1 and NMDA receptors (Ito et al., 2007). 

Findings

ST101 has been shown to improve the memory deficits observed in mice following olfactory bulbectomy (Han et al., 2008).
