Chesterford Research Park, UK, 15 September, 2003 - BioFocus plc (AIM: BIO), a
world leader in collaborative drug discovery, today announces that it has

discovery expertise in assay development, high throughput screening, medicinal
chemistry and molecular informatics. In return, BioFocus receives compensation
