Albizziin is a glutamase inhibitor and is a glutaminyl-tRNA synthetase inhibitor.

Pyridoxal 5′-phosphate the active form of vitamin B6 is a cofactor for many different enzymes involved in transamination reactions including mitochondrial cysteine desulfurase cystathionine γ-synthase various aminotransferases and a d-serine dehydratase.

Humanin, an anti-apoptotic peptide of 24 amino acids, is a Bax inhibitor. Humanin prevents the translocation of Bax from cytosol to mitochondria, blocks Bax from the inactive to active conformation. Humanin is a mitochondria-associated peptide with a neuroprotective effect against AD-related neurotoxicity. Humanin also improves overall insulin sensitivity in animal. Humanin are related to aging. Humanin analogue, in which the serine at position 14 is replaced by glycine, names HNG.
