d-proline is also contained in Trapoxin B (9), Chlamydocin (10), and Apicidin B (11) (), naturally occurring tetrapeptides that show a potent antiprotozoal activity by inhibiting histone deacetylase (HDAC), an enzyme that plays a key role in inducing or reversing gene transcription [33,34].].

Proline

Proline (symbol Pro or P) is an organic acid classed as a proteinogenic amino acid (used in the biosynthesis of proteins), although it does not contain the amino group-NH 2 but is rather a secondary amine.The secondary amine nitrogen is in the protonated NH 2 + form under biological conditions, while the carboxy group is in the deprotonated −COO − form.
