It is believed that odor transduction in the mammalian main olfactory system only involves the cAMP-signaling pathway. Here, we report on odor responsiveness in mice with a disrupted cyclic nucleotide-gated (CNG) channel subunit A2. Several odorants, including putative pheromones, can

Intraperitoneal administration of 2,5-dimethylpyrazine (2,5-DMP) was found to inhibit oxytocin- and prostaglandin F2alpha-induced tetanic uterine contractions in normal or pregnant female rats. This suggests that 2,5-DMP may be used as a countercontraction agent or relaxant for preventing oxytocic agent-induced medical
