S6 peptide is a potentially important lamin kinase. S6 peptide is involved in the process of cardiac hypertrophy induced by mechanical loading. S6 peptide can be activated by many kinds of growth factors.

Etiprednol dicloacetate (BNP-166) is a corticosteroid with anti-inflammatory activity.

Aminomalonic acid (Ama) was first detected in alkaline hydrolysates of proteins in 1984. Ama has been isolated from proteins of Escherichia coli and human atherosclerotic plaque. The presence of Ama has important biological implications because the malonic acid moiety potentially imparts calcium binding properties to protein.
