The nonpeptide neurotensin (NT) antagonist, SR 48692, was recently shown to inhibit NT binding to the cloned rat and human NT receptor and to antagonize NT effects in a variety of in vitro and in vivo assays. Here, we show that, in contrast to its antagonistic action on NT-induced hypomotility in the rat, SR 48692 failed to antagonize NT-induced hypothermia and analgesia in the mouse and rat. We suggest that these effects might be mediated through a subtype of SR 48692-insensitive NT receptor.
非肽类神经降压素(NT)拮抗剂SR 48692最近被证明可抑制NT与克隆的大鼠和人类NT受体的结合,并在多种体外和体内试验中拮抗NT的作用。在此,我们表明,与它对大鼠NT诱导的运动减退的拮抗作用相反,SR 48692未能拮抗小鼠和大鼠中NT诱导的体温过低和镇痛作用。我们认为这些效应可能是通过一种对SR 48692不敏感的NT受体亚型介导的。
