The synthesis and biological properties of two new oxytocin analogs having stable methylenedithioether bonds in place of the S-S bridge, isosteric to the oxytocin trisulfides, are described. The activities of the analogs having -S-carba-S-bridge are decreased in comparison to that of oxytocin in all tests by the factor 10-50. Their activity is about 2 fold lower than the activity of the appropriate trisulfide analogs.
