Lobetyol is a natural compound that can be isolated from Lobelia chinensis. Lobetyol induces apoptosis and cell cycle arrest in MKN45 cells. Lobetyol shows anti-virus, anti-inflammation and anti-tumor activity. Lobetyol is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Sodium metatungstate is a potent inhibitor of ecto-nucleoside triphosphate diphosphohydrolase (NTPDase)(Ki values of 2.58 μM, 3.26 μM, and 28.8 μM for NTPDase 1, NTPDase 3 and NTPDase 2 respectively).

EH-201 is a low MW inducer of erythropoietin. EH-201 induces expression of erythropoietin PPAR-γ coactivator 1α (PGC-1α) and haemoglobin in astrocytes and PC12 neuronal-like cells. In vivo EH-201 treatment restores memory impairment as assessed by the passive avoidance test in SD Aβ and KA mouse models.
