UNC1999は経口投与のEZH2(IC50=2nM)とEZH1(IC50=45nM)の阻害剤である[1-2]。UNC1999は、遺伝子発見の制御、癌の進行と幹細胞の維持におけるEZH2とEZH1のメカニズムの調査に使われることが可能である[3-4]。
体外で、UNC1999(2.5–5μM)でヒト結腸癌細胞(HCT116、LoVo、HCT-15、DLD-1)を24-72時間処理した結果、LC3B遺伝子発見を転写的に上方制御することで、オートファジーを誘発し、小胞体(ER)ストレス、折り畳まれなかったタンパク質反応(UPR)のPERK/eIF2α経路を活性化し、最終的には腫瘍の細胞死を促進した[5]。ヒト膀胱癌細胞株E-Jと5637をUNC1999(0.1–100μM)で24-120時間処理した結果、UNC1999は、EZH2の活性を抑制し、JAK2/STAT3シグナル伝達経路を遮断することで、細胞の増殖、遊離を著しく阻害し、同時にアポトーシスを誘発する[6]。
体内で、MM.1Sヒト多発性黒色腫異種移植片を持つNOGマウスに、UNC1999(15–25mg/kg)を3週間、週に二回腹腔内注射した結果、腫瘍の成長を著しく阻害し、生存期間を延ばす[7]。Y79ヒト網膜芽細胞腫細胞を接種したBALB/cヌードマウスに、UNC1999(25mg/kg)を4週間、週に二回腹腔内注射した結果、皮下の異種移植腫瘍の成長を著しく抑制する[8]。

| 細胞実験[1]: | |
細胞株 | E-Jと5637細胞(ヒト膀胱癌細胞株) |
準備方法 | 37°C、5% CO₂で、10%のウシ胎児血清(FBS)を添加したRPMI 1640培地でE-Jと5637細胞を培養した。濃度が0.1、1、10と100µMのEZH2阻害剤UNC1999で細胞を24、72と120時間処理した。 |
反応条件 | 0.1-100µM;24-120時間 |
アプリケーション | UNC1999は用量と時間依存的に、膀胱癌細胞の増殖を著しく阻害した。UNC1999は著しいアポトーシスを誘発し、細胞の遊離と浸潤を抑制した。機構的に、UNC1999はJAK2とSTAT3のリン酸化レベルを減らし、JAK2/STAT3シグナル伝達経路の阻害を示唆した。 |
| 動物実験 [2]: | |
動物モデル | BALB/cヌードマウス |
準備方法 | Y79網膜芽細胞腫細胞を、雌BALB/cヌードマウスの後腹部に皮下注射した。一週間の腫瘍成長期の後、マウスをランダムに二つのグループに分けた。うち一つのグループには、UNC1999(25mg/kg、腹腔内注射)を3週間、週に二回投与した。対照群には、溶媒(コーン油の中の5%のDMSO)を腹腔内注射した。腫瘍の体積を週に三回測定した。4週後にマウスを殺処分し、更なる分析の為に、腫瘍を採取した。 |
投与形態 | 25mg/kg;腹腔内注射;3週間、週に二回 |
アプリケーション | 溶媒対照物と比べ、UNC1999の投与は、体内で、網膜芽細胞腫異種移植腫瘍の成長を著しく阻害した。UNC1999の処理は、EZH2とリン酸化STAT3(pY-STAT3)のタンパク質レベルを減らし、同時に切除された腫瘍でFoxO1の発見を増やした。 |
