Travoprost is an isopropyl ester prodrug and a high-affinity, selective FP prostaglandin receptor agonist.

Rotundine is an antagonist of dopamine D1, D2 and D3 receptors.

Agrostemmoside E is a patented compound by Aktin and is an acetylated triterpene saponin isolated from Agrostemma githago L.as an intracellular gene-delivery enhancer, demonstrating substantially increased transfection efficiency of gene-loaded nanoplexes together with high cellular tolerance. These properties make Agrostemmoside E a promising candidate for next-generation nucleic-acid and gene-delivery systems.
