Inosinic acid (IMP)はプリンの代謝で重要な役割を果たすヌクレオチドであり、食物の重要な風味増強剤である[1]。Inosinic acidは更にアデノシン一リン酸(AMP)とグアノシン一リン酸(GMP)に変換し、細胞内のエネルギー代謝プロセスに関与する[2]。Inosinic acidはよく食品添加物(E630)として使われ、グルタミン酸ナトリウム(MSG)と併用する場合、Inosinic acidは食物の旨みを著しく増強し、飼料の添加物に広く使われる[3]。Inosinic acidは、免疫調節と神経保護で、潜在的な研究の価値をも示す[4]。
体外で、Inosinic acid (15mM)でlineage⁻/low骨髄細胞を15-30分間処理した結果、pAktとpS6シグナル伝達経路を活性化し、cKit膜の発見の上方制御を刺激し、顆粒球マクロファージ前駆細胞(GMP)の増殖を促進し、Gr-1⁺顆粒球の生成を促進した[5]。
体内で、Inosinic acid (45mg/kg)をX線の照射の15分後に腹腔内注射し、7Gy全身照射を受けた雄のKv:SHK系統マウスを処理した。Inosinic acidは致死量の照射の後、生存率を著しく増やし、放射線誘発性白血球減少症と血小板減少症を軽減し、骨髄と胸腺細胞におけるDNA損傷のレベルを減らした[6]。Inosinic acid (1000mg/kg)を、敗血症を患う10から12週齢のC57BL/6Jマウスに腹腔内注射した。Inosinic acidは、敗血症におけるTNF-αの産生を著しく阻害し、IL-10のレベルを増強した[7]。

| 細胞実験[1]: | |
細胞株 | 系統的/低骨髄細胞(マウス造血前駆細胞) |
準備方法 | 系統細胞除去キットで、系統的/低骨髄細胞を野生型C57BL/6マウス骨髄から単離した。37°C、5%のCO₂で10ng/mLの幹細胞因子、10ng/mLのトロンボポエチンと10ng/mLのIL-3を転化したSFEM培地で細胞を培養した。0-15mMの濃度で、Inosinic acidで細胞を24-72時間処理した。 |
反応条件 | 0-15mM;24-72時間 |
アプリケーション | Inosinic acidの処理は、顆粒球-単球前駆細胞(GMP)の増殖とGr-1+顆粒球の産生を用量依存的に著しく刺激した。Inosinic acidは、対照細胞と比べて、GMP細胞へのBrdUの取り込みを1.3倍増強させ、Gr-1+細胞の割合を1.4倍増強させた。 |
| 動物実験 [2]: | |
動物モデル | C57BL/6マウス |
準備方法 | LPS (10mg/kg、腹腔内)投与の30分前に、マウスにはInosinic acid (1000mg/kg)を腹腔内投与した。サイトカイン分析の為に、血漿と臓器サンプル(膵臓、肝臓、肺)をLPSの90分後に採取した。細菌敗血症モデルについて、Inosinic acid (1000mg/kg、腹腔内注射)は、盲腸の結紮と穿刺(CLP)、または鼻腔内細菌感染症(肺炎球菌と大腸菌)の1時間前に投与した。 |
投与形態 | 1000mg/kg;腹腔内注射 |
アプリケーション | Inosinic acidは、エンドトキセミアマウスで、TNF-αの産生を著しく抑制し、IL-10のレベルを増やした。 |
