A homodetic cyclic peptide is a cyclic peptide in which the ring consists solely of amino-acid residues in peptide linkages.

| aminocandin | A member of the family of echinocandins that shows broad-spectrum in vitro activity against Aspergillus and Candida spp. | aminocandin |
| astressin | A 30-membered homodetic cyclic peptide comprising the sequence D-Phe-His-Leu-Leu-Arg-Glu-Val-Leu-Glu-Nle-Ala-Arg-Ala-Glu-Gln-Leu-Ala-Gln-Glu-Ala-His-Lys-Asn-Arg-Lys-Leu-Nle-Glu-Ile-Ile-NH2 cyclised by an amide bridge, formed by condensation of the side-chain carboxy group of the Glu residue at position 19 and the side-chain amino group of the Lys residue at position 22. | astressin |
| baci-im | A homodetic cyclic peptide consisting of (4R)-2-[(1S,2S)-1-amino-2-methylbutyl]-4,5-dihydro-1,3-thiazole-4-carboxylic acid attached head-to-tail to L-leucyl,D-glutamyl, L-lysyl, D-ornityl, L-isoleucyl, D-phenylalanyl, L-histidyl. D-aspartyl and L-asparaginyl residues coupled in sequence and cyclised by condensation of the side-chain amino group of the L-lysyl residue with the C-terminal carboxylic acid group. It is the major component of bacitracin. | bacitracin A zwitterion; bacitracin A |
| cyclo(leucyl-prolyl) | A homodetic cyclic peptide composed from leucyl and prolyl residues. | cyclo(L-Leu-L-Pro) |
| cyclosporine | A cyclic nonribosomal peptide of eleven amino acids; an immunosuppressant drug widely used in post-allogeneic organ transplant to reduce the activity of the patient's immune system, and therefore the risk of organ rejection. Also causes reversible inhibition of immunocompetent lymphocytes in the G0- and G1-phase of the cell cycle. | cyclosporin A |
| eptifibatide | A synthetic homodetic cyclic peptide comprising N(alpha)-(3-sulfanylpropanoyl)homoarginyl, glycyl, aspartyl, tryptophyl, prolyl and cysteinamide residues connected in sequence and cyclised via a disulfide bond. Derived from a protein found in the venom of the southeastern pygmy rattlesnake, Sistrurus miliarus barbouri, eptifibatide is an anti-coagulant that inhibits platelet aggregation by selectively blocking the platelet glycoprotein IIb/IIIa receptor, so preventing the binding of fibrinogen, von Willebrand factor, and other adhesive ligands. It is used in the management of unstable angina and in patients undergoing coronary angioplasty and stenting procedures. | eptifibatide |
| gramicidin s | | gramicidin S |
| hc toxin | A homodetic cyclic tetrapeptide made up from L-alanyl, D-alanyl, L-prolyl and 2-amino-8-oxo-9,10-epoxydecanoyl residues. | HC toxin |
| histidyl-proline diketopiperazine | A homodetic cyclic peptide resulting from the formal condensation of both the amino and acid groups of L-histidine with the acid and amino groups of L-proline. It is a metabolite of thyrotropin-releasing hormone (TRH). | cyclo(L-His-L-Pro) |
| lugdunin | A thiazolidine-containing homodetic cyclic peptide that is isolated from human nasal bacteria. Exhibits bactericidal activity against many major pathogens including methicillin-resistant Staphylococcus aureus (MRSA). | lugdunin |
| maculosin | A homodetic cyclic peptide that is a dipeptide composed of L-proline and L-tyrosine joined by peptide linkages. | maculosin |
| pasireotide | A six-membered homodetic cyclic peptide composed from L-phenylglycyl, D-tryptophyl, L-lysyl, O-benzyl-L-tyrosyl, L-phenylalanyl and modified L-hydroxyproline residues joined in sequence. A somatostatin analogue with pharmacologic properties mimicking those of the natural hormone somatostatin; used (as its diaspartate salt) for treatment of Cushing's disease. | pasireotide |
| phallacidin | A homodetic bicyclic heptapeptide having a sulfide bridge. | phallacidin |
| phalloidine | A homodetic bicyclic heptapeptide having a sulfide bridge. | phalloidin |
| sdz psc 833 | | SDZ PSC 833 |
| trapoxin a | A homodetic cyclic tetrapeptide constructed from L-phenylalanyl (x2), D-pipecolinyl and L-2-amino-8-oxo-9,10-epoxydecanoyl residues. | trapoxin A |
| tyrocidine | A homodetic cyclic decapeptide consisting of D-Phe, L-Pro, L-Phe, D-Phe, L-Asn, L-Gln, L-Tyr, L-Val, L-Orn, and L-Leu residues coupled in sequence and cyclised head-to-tail. | tyrocidine A |
