Mirabamide

Mirabamides are sea sponge isolates that inhibit HIV-1 fusion.^[1] Variants A to D are known from Siliquariaspongia mirabilis and E through H are derived from Stelletta clavosa.^[2] 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.^[3]
