  Synthesis and structure–activity relationships of new carbonyl guanidine derivatives as novel dual 5-HT2B and 5-HT7 receptor antagonists. Part 2

  摘要：

  We previously reported that the novel dual 5-HT₂B and 5-HT7 receptor antagonist N-(9-hydroxy-9H-fluorene-2-carbonyl)guanidine (4) exerted a suppressing effect on 5-HT-induced dural protein extravasation in guinea pigs. To develop a synthetic strategy, we performed docking studies of lead compound 4 bound to 5-HT₂B and 5-HT₇ receptors, and observed that the carbonyl guanidine group forms a tight interaction network with an active center Asp (D135:5-HT2B, D162:5-HT₇), Tyr (Y370:5-HT₂B, Y374:5-HT₇) and aromatic residue (W131:5-HT2B, F158:5-HT₇). Based on molecular modeling results, we optimized the substituents at the 5- to 8-position and 9-position of the fluorene ring and identified N-(diaminomethylene)-9-hydroxy-9-methyl-9H-fluorene-2-carboxamide (24a) exhibits potent affinity for 5-HT₂B (Ki=4.3 nM) and 5-HT7 receptor (Ki=4.3 nM) with high selectivity over 5-HT₂A, 5-HT₂C, α₁, D₂ and M₁ receptors. Compound 24a reversed the hypothermic effect of 5-carboxamidotryptamine (5-CT) in mice and also showed a suppressing effect on 5-HT-induced dural protein extravasation in guinea pigs when orally administered at 30 mg/kg. Compound 24a is therefore a promising candidate for a novel class of anti-migraine agent without any adverse effects.

  This invention relates to a novel fluorene derivative having a characteristic structure in which guanidino group or the like functional group is linked to the fluorene structure via carbonyl group, or a salt thereof. The compound of the invention has an advantage in that it has high affinity for serotonin receptor subtypes, particularly for 5-HT 2B receptor and 5-HT 7 receptor, and shows excellent pharmacological effects in comparison with the conventional compounds which have only one of the antagonistic activities of 5-HT 2B receptor and 5-HT 7 receptor, this is useful as a prophylactic antimigraine agent having high safety and excellent effect.

  这项发明涉及一种新颖的芴衍生物，其具有特征结构，其中脲基或类似的官能团通过羰基与芴结构连接，或其盐。该化合物具有优点，即它对5-HT2B受体和5-HT7受体等血清素受体亚型具有高亲和力，并与仅具有5-HT2B受体和5-HT7受体拮抗活性之一的传统化合物相比，显示出出色的药理效应，因此可用作具有高安全性和出色效果的预防性抗偏头痛剂。

  The present invention relates to prophylactic antimigraine agents comprising as an active ingredient a dual antagonist for the 5-HT 2B and 5-HT 7 receptors, the antagonist having a binding affinity selective for the 5-HT 2B and 5-HT 7 receptors. Since these prophylactic antimigraine agents show an excellent pharmacological effect in comparison with the cases in which a 5-HT 2B receptor antagonist having a selective binding affinity to the 5-HT 2B receptor or a 5-HT 7 receptor antagonist having a selective binding affinity to the 5-HT 7 receptor is used alone, they are useful as drugs which are excellent in prophylaxis of migraine and in which the side effects found in the existing prophylactic antimigraine agents are reduced.

  本发明涉及预防偏头痛的药物，其作为活性成分包括对5-HT2B和5-HT7受体的双重拮抗剂，该拮抗剂具有选择性结合5-HT2B和5-HT7受体的结合亲和力。由于这些预防性抗偏头痛药物与仅使用具有选择性结合亲和力的5-HT2B受体拮抗剂或5-HT7受体拮抗剂相比，表现出优异的药理作用，因此它们是在预防偏头痛方面优秀的药物，其中减少了现有预防偏头痛药物中发现的副作用。

  The invention relates to a medicament for IBS, which comprises a dual antagonist for 5-HT 2B and 5-HT 7 receptors having selective binding affinities for 5-HT 2B and 5-HT 7 receptors. The pharmaceutical composition of the invention is useful as a drug which is excellent in the therapeutic effect on IBS and shows lessened side effects occurring in the existing remedies for IBS, because it showed good pharmacological actions in comparison with the case of independently using a 5-HT 2B receptor antagonist having selective binding affinity for 5-HT 2B receptor or a 5-HT 7 receptor antagonist having selective binding affinity for 5-HT 7 receptor.

  本发明涉及一种治疗肠易激综合征（IBS）的药物，包括一种对5-HT2B和5-HT7受体具有选择性结合亲和力的双重拮抗剂。本发明的制药组合物作为一种药物对IBS具有优异的治疗效果，并且与现有的IBS治疗药物相比，具有减少副作用的优点，因为与单独使用具有选择性结合亲和力的5-HT2B受体拮抗剂或5-HT7受体拮抗剂相比，它表现出良好的药理作用。
