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.

RGD peptide (GRGDNP) (TFA) promote apoptosis through activation of conformation changes that enhance pro-caspase-3 activation and autoprocessing.

Robustaflavone is a biflavonoid isolated from Doradilla that has natriuretic properties.
