Disclosed are Agonists and Antagonist of bombesin which are derivatives of naturally occurring bombesin possessing a methyl sulfide or a methyl amide bond connecting the two amino acids on he carboxy terminal end. Agonist and antagonist activities are confirmed using conventional competitive binding and biochemical assays as well as conventional physiological tests and the use of these derivatives in a variety of conditions. Use of these peptides include stimulating or antagonizing growth of tissues, especially lung, and a means for effecting treatment for digestional disorders.
