N2  - Three related peptides, caeridins 1.1-1.3, have been isolated from the green tree frog Litoria gilleni. Caeridins 1.1 and 1.2 are dodecapeptides differing only in having &#945; and &#946; Asp at residue 4 [viz. Gly Leu Leu Asp Gly Leu Leu Gly Thr Leu Gly Leu (NH2)]. Caeridin 1.3 is the corresponding cyclic amino succinyl derivative derived formally by cyclization of Asp(4) and Gly (5). Hydrolysis of caeridin 1.3 yields caeridin 1.1 and 1.2 in the ratio 3:1. This constitutes a rare case of the isolation of three such related peptides from a natural system.
