Pescidic acid is a component of AquaCacteen elixir from organic cactus. AquaCacteen blocks the release of stress markers from sensory nerve cells in the skin and calms irritated skin. Pescidic acid as a part of this elixir acts as an iron chelator, which binds free Fe2+/Fe3+ ions. In skin tissue, Fe2+ is normally bound to ferritin, but UV can decompose this complex leading to the liberation of Fe ions. These ions initiate the formation of OH radicals, thus pescidic acid prevents the formation of ROS by complexing Fe2+. Recent studies showed that the ability of a piscidic acid to inhibit HMG-CoA reductase, an enzyme participated in the biosynthesis of cholesterol, could be useful in the development of new functional foods and pharmaceutical products.

(1'S,2'S)-nicotine-1'-N-oxide is a stereoisomer of nicotine-1'-N-oxide, an oxidation product of S-(-)-nicotine. N-1'-oxidation of nicotine is mediated via flavin-containing monooxygenase. A marked stereoselectivity has been observed in the formation of N-1'-oxide metabolites from nicotine. Mammal hepatic preparations generally produce more the N-1'R,2'S-cis diastereoisomer than N-1'S,2'S-trans diastereoisomer after incubation with S-(-)-nicotine. (1'S,2'S)-nicotine-1'-N-oxide was reported to bind alpha3beta4 neuronal nicotinic acetylcholine receptor. cis- and trans-nicotine-N'-oxides modulate the development of tumors in rats initiated with N-[4-(5-nitro-2-furyl)-2-thiazolyl]formamide.

Aurodox is an antibiotic obtained from a streptomyces variant considered as possibly effective against streptococcus pyogenes infections. It may promote growth in poultry. Aurodox inhibits protein biosynthesis by binding to elongation factor Tu (EF-Tu). Aurodox has being shown to possess the ability to inhibit the secretion of type III-secreted proteins without affecting bacterial growth.

Bisbenzimide ethoxide is a fluorescent nucleic acid stain useful for DNA labeling in fluorescence microscopy and flow cytometry. It appears to bind to AT-rich regions containing at least four such basepairs. Bisbenzimide ethoxide seems to bind relatively poorly to nucleotide sequences containing the alternating step TpA. Bisbenzimide ethoxide induced apoptosis in the HL-60 cells in a time- and dose-dependent manner. Endogenous nuclear topoisomerase I activity in HL-60 cells was inhibited by treatment with Bisbenzimide ethoxide.
