(Z)-1-Methyl-2-(undec-6-enyl)quinolin-4(1H)-one shows strong inhibitory activity on leukotriene biosynthesis in human polymorphonuclear granulocytes, and it is very effective against mycobacteria.

Egg-laying hormone (ELH) is a neuropeptide synthesized by the bag cell neurons, Egg-laying hormone (ELH) induces egg laying and its correlated behavior in Aplysia californica. Egg-laying hormone (ELH) has been purified to homogeneity and Egg-laying hormone (ELH)'s primary structure has been determined. Egg-laying hormone (ELH) have 36 amino acid residues with a Mr of 4385 and a calculated isoelectric point of 9.7. Egg Laying Hormone of Aplysia induces a voltage-dependent slow inward current carried by Na+ in an identified motoneuron.

4-Azido-L-phenylalanine (p-Azido-L-phenylalanine) is an amino acid derivative that acts as a photoaffinity marker and can be used to detect localized protein environments.
