Images of Axinella verrucosa show a sponge with a typically lobate/rounded, “finger-glove” or cushion-like growth form, with a wrinkled or papillose surface texture and a surface that can appear light to medium beige/tan (sometimes with darker or more orange-brown tones). The overall aspect in photographed observations is of a relatively solid, encrusting-to-lobate body rather than a thin, delicate net-like sponge.
Axinella verrucosa is reported to contain bromopyrrole alkaloids. In a study of a Mediterranean sponge collection, extracts yielded the antibacterial constituent hymenidin and a novel alkaloid, debromo-carteramine A, co-occurring with carteramine A.
In disc-diffusion assays against an environmental marine bacterium (Lysinibacillus sp. strain ESY 9), hymenidin and debromo-carteramine A showed measurable antibacterial activity, whereas carteramine A was reported inactive under the tested conditions. The authors additionally suggest that lack of a bromine substituent at the C-2 position (i.e., a “free position” at C-2) is important for antibacterial activity in this assay context.
