p>Aaptos aaptos and Petrosia sp. sponges are known for their ability to produce potential marine bioactive compound. As a metazoan animal with simple body structure, the morphology and it association with symbiont-bacteria could influence their bioactive

Many natural products have been isolated from the cryptic species of the Indonesian marine sponge. Despite this, it remains unclear how sponges produce such a diverse array of metabolites and their relationship to sponge diversity. During our expedition

Marine sponges, which belong to the phylum Porifera (Metazoa), are considered the single best source of marine natural products. Among them, members of the genus Aaptos are attractive targets for marine natural product research owing to their abundant

A novel heteroaromatic substance, aaptamine possessing an α-adrenoceptor blocking activity has been isolated from the tropical sea sponge Aaptos aaptos and its structure has been determined to be 1 on the basis of spectral data and chemical degradation.
