sponge Sponges or sea sponges are primarily marine invertebrates of the animal phylum Porifera (; meaning 'pore bearer'), a basal clade and a sister taxon of the diploblasts. They are sessile filter feeders that are bound to the seabed, and a ...
isolates that inhibit HIV-1 fusion. Variants A to D are known from ''Siliquariaspongia mirabilis'' and E through H are derived from ''Stelletta clavosa''. Mirabamides have a macrocyclic region closed through an ester bond between the C-terminus and a 𝛽-hydroxyl group, and terminated with a polyketide moiety or a more simple branched aliphatic acid. Mirabamide G is a fusion of several amino acids: 2,3 diamino butanoic acid, 3-hydroxyleucine, N-methylthreonine, 2,3-dihydroxy-2,6,8-trimethyldeca-(4''Z'',6''E'')-dienoic acid, 3-methoxy alanine, β-methoxytyrosine, 3,4-dimethylglutamine.
