  <description>Atosiban is an organic compound with the chemical formula C43H67N11O12S2. Atosiban belongs to the amino acids, peptides, and analogues, a subclass of carboxylic acids and derivatives within the organic compounds. With an average molecular weight of 994.19 g/mol, Atosiban is a heavy molecule.

The compound is recorded as being found in or released from two sources: electrical and electronic equipment antennas, and gynecological pharmaceuticals and veterinary products. The recorded route of exposure for this substance is intravenous. Atosiban acts upon four recorded protein targets, serving as an antagonist of the oxytocin receptor (OXTR), the vasopressin V1a receptor (AVPR1A), the vasopressin V1b receptor (AVPR1B), and the vasopressin V2 receptor (AVPR2).</description>
