Imazapic has a broad herbicidal spectrum and controls a variety of annual grass weeds.

D-proline is an isomer of the naturally occurring amino acid L-Proline. D-amino acids have been found in relatively high abundance in human plasma and saliva. These amino acids may be of bacterial origin but there is also evidence that they are endogenously produced through amino acid racemase activity.

Defensin HNP-3 human is a cytotoxic antibiotic peptide known as "defensin". Defensin HNP-3 human has inhibitory activity against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. Defensin HNP-3 human is initially synthesized as the 94 amino acids preproHNP(1-94), which is hydrolyzed to proHNP(20-94) and converted to mature HNP(65-94) after the removal of anion precursors.
