* Macclesfield, U.K.-based drug discovery company Proteus International plc, which specializes in applying computer-aided molecular modeling to immunotherapeutics, has formed a collaboration with ChemBridge Corporation Inc., of San Diego. The companies say combining Proteus' computer-aided molecular design with ChemBridge's combinatorial chemistry will enable them to speed up the process of generating novel drug candidates. The two plan to develop and market a service for finding molecules to fit targets specified by pharmaceutical industry partners.
