摘要
Chemokine receptor antagonists that held much promise for the treatment of autoimmune and inflammatory diseases have recently performed poorly in clinical trials, resulting in disappointment for both pharmaceutical companies and patients. This review focuses on the redundancy of the molecular target as one potential reason for the failure of some of these antagonists to fulfil their initial promise, and discusses the use of drugs that are capable of interacting with more than one drug target - so-called promiscuous drugs as possible approaches to overcome this difficulty. Several clinically approved promiscuous drugs, such as aspirin and olanzapine, are already used successfully. This review discusses examples of promiscuous drugs for G-protein-coupled receptors, including progress in developing dual-specific chemokine receptor antagonists, and considers evidence for the possible therapeutic utility of such drugs.
