Abstract
A method for identifying, in vitro, distinct, drug-resistant, biologically-active mutants of a protein that may emerge in vivo in response to a drug targeted against the protein is disclosed. The method involves preparing, by heterologous expression of a library of nucleotide sequences, a complete library of mutant proteins accessible in a single generation. The mutant proteins from the library that are drug resistant are identified. When all the first generation mutants have been identified in the above manner, a combination of drugs can be identified that will block the development of resistance. The same technique allows evaluation of the ultimate clinical efficacy of a drug targeted against the protein by comparing the number of resistant first generation mutants. A preferred protein is an HIV protease.
