A new chlorobenzoate derivative from the red alga Solieria sp.

A new chlorobenzoate derivative, solieriate (1), together with six known compounds (2–7), were isolated from the red alga Solieria sp. The structures of 1–7 were determined by comprehensive spectroscopic methods and X-ray diffraction analysis. Compound 1 is the first example of halogenated derivative isolated from this genus. In addition, 1 exhibited moderate antibacterial activity on A. baumannii with MIC value of 64 μg/ml.
