RS 127445は経口活性で、高い選択性を持つ5-HT2B受容体拮抗剤であり、pKiは9.5であり、5-HT2Bに対する選択性は、5-HT2Aや5-HT2Cなど他の関連受容体よりも1000倍以上高かった[1, 2]。5-HT2B受容体は、中枢と末梢神経系で重要な役割を果たし、心血管効果や神経細胞の感作など様々な生理機能の制御に関与している[3]。RS 127445は側坐核でドーパミン神経伝達を阻害できる[4]。
体内で、RS 127445 (1-30mg/kg)をマウスに腹腔内注射した結果、腸の蠕動運動を著しく阻害し、排便量を用量依存的に減らした[5]。RS 127445 (10mg/kg)は経口投与の場合、実験性内臓過敏症ラットで、拘束ストレスによる内臓過敏症を著しく阻害し、阻害率は74%で、排便をも減らした[6]。

| 動物実験 [1]: | |
動物モデル | 成体した雄C57BL/6Jマウス |
準備方法 | 3mL/kgの最終投与体積で、試験化合物(RS 127445 1、3、10または30mg/kg)または溶媒(10%のエタノール、40%のポリエチレングリコール、50%の蒸留H2O)を動物に腹腔内投与した。投与後、動物をケージに戻した。処理の3時間後、排出された糞便を採取し、量った;ペレットを紙製のトレイライナーに集め、尿または水からの汚染を最小限に抑えた。個体のラットから排泄された糞便ペレットの数と大きさに大きな差がある為、結果を、排泄されたペレットの平均湿重量SEMとして表した。 |
投与形態 | 1、3、10または30mg/kg;腹腔内注射 |
アプリケーション | RS 127445 (1-30 mg/kg)は用量依存的に排便量を減らし、用量が10と30mg/kgの場合は特に著しかった。 |

Calculation results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
