A tetronic acid (5), 5-[13-(furan-3-yl)-2,6,10-trimethyltrideca-2,6,8-trienyl]-4-hydroxy 3-methylfuran-2(5H)-one,* with weak antimicrobial activity has been isolated from the sponge Psammocinia sp. and characterized by analysis of 1H and 13C n.m.r. data including 'H-1H correlation (COSY) experiments. The compound may be identical to a tetronic acid isolated by the Roche group, previously assigned structure (3).

Spectroscopic Characteristics

A new sesterterpene tetronic acid (5) exhibiting antimicrobial activity has been isolated from an Australian marine sponge, Psammocinia sp., and its structure secured by detailed spectroscopic analysis. The tetronic acid (5) possesses almost identical spectroscopic characteristics to, and is a structural isomer of, the known marine natural product (6) previously reported from an Australian sponge.

Lack Of Information

Marine sponge associated fungi are known as potential source of metabolites with various biological activities. Natural pigment is one of metabolite which produced by microorgisms. Several researches reported the antimicrobial activity from natural pigment. Unfortunatelly there are lack of information about marine fungi natural pigment and its producer. The aims of this research were to identify yellow pigmented Indonesian marine sponge-associated fungi, to extract the pigment, and to study the antimicrobial activity of the pigment against clinical MDR bacteria and clinical pathogenic fungi. Sponge associated-fungus isolate MT23 was successfully identified as Trichoderma parareesei. The fungal pigment could be extracted only in methanol with yield 6,22±0,29%. The pigment could inhibitted S. typhi and E. coli MDR strains. The biggest antibacterial activity was shown by concentration 1000µg/mL against S. typhi with inhibition zone was 4.03±0.06 mm.
