Ritodrine 102-111 oxytocin/neurophysin I prepropeptide Homo sapiens 12-20 7536662-8 1995 Moreover, 1 microM ritodrine, which is known to relax uterine muscle contraction, attenuated oxytocin-induced MAP kinase activity and phosphorylation. Ritodrine 19-28 oxytocin/neurophysin I prepropeptide Homo sapiens 93-101
