Structure-based design of six novel classes of nonpeptide antagonists of the bradykinin B2 receptor.
Six classes of nonpeptide bradykinin antagonists were designed using a template derived from structural studies of peptide antagonists. Several compounds from each class were synthesized and assayed for binding to the human bradykinin B2 receptor. Each family showed compounds active at the level of the smallest template peptide; three classes contained compounds with Kd < 8 microM. These results provide diverse leads for a medicinal chemistry-based optimization program.
