Sample solution is provided at 25 µL, 10mM.
UNC1999 is an orally active inhibitor of EZH2 (IC50=2nM) and EZH1 (IC50=45nM)[1-2]. UNC1999 can be used to investigate the mechanisms of EZH2 and EZH1 in gene expression regulation, cancer development, and stem cell maintenance[3-4].
In vitro, treatment of human colorectal cancer cells (HCT116, LoVo, HCT-15, DLD-1) with UNC1999 (2.5–5μM) for 24–72 hours induces autophagy by upregulating LC3B gene expression transcriptionally, activates endoplasmic reticulum (ER) stress and the PERK/eIF2α pathway of the unfolded protein response (UPR), ultimately promoting tumor cell death[5]. UNC1999 (0.1–100μM) treatment of human bladder cancer cell lines E-J and 5637 for 24–120 hours, UNC1999 significantly inhibits cell proliferation and migration while inducing apoptosis by suppressing EZH2 activity and blocking the JAK2/STAT3 signaling pathway[6].
In vivo, intraperitoneal injection of UNC1999 (15–25mg/kg) twice weekly for 3 weeks in NOG mice bearing MM.1S human multiple myeloma xenografts significantly inhibits tumor growth and prolongs survival[7]. Intraperitoneal injection of UNC1999 (25mg/kg) twice weekly for 4 weeks in BALB/c nude mice inoculated with Y79 human retinoblastoma cells significantly suppresses the growth of subcutaneous xenograft tumors[8].

UNC1999是一种口服活性的EZH2(IC50=2nM)和EZH1(IC50=45nM)抑制剂[1-2]。UNC1999可用于研究EZH2和EZH1在基因表达调控、癌症发生发展以及干细胞维持中的作用机制[3-4]。
在体外,UNC1999(2.5–5μM)处理人结直肠癌细胞(HCT116, LoVo, HCT-15, DLD-1)24–72小时,UNC1999通过转录上调LC3B基因表达诱导细胞自噬,并激活内质网应激(ER stress)及未折叠蛋白反应(UPR)的PERK/eIF2α通路,最终促进肿瘤细胞死亡[5]。UNC1999(0.1–100μM)处理人膀胱癌细胞系E-J和5637 24–120小时,UNC1999通过抑制EZH2活性并阻断JAK2/STAT3信号通路,显著抑制细胞增殖和迁移、诱导细胞凋亡[6]。
在体内,UNC1999(15–25mg/kg)每周2次腹腔注射,用于处理携带MM.1S人多发性骨髓瘤异种移植瘤的NOG小鼠,持续3周,显著抑制了肿瘤生长并延长了小鼠生存期[7]。UNC1999(25mg/kg)每周两次腹腔注射,用于处理接种了Y79人视网膜母细胞瘤细胞的BALB/c裸鼠,持续4周,UNC1999显著抑制了皮下移植瘤的生长[8]。
| Cell experiment [1]: | |
Cell lines | E-J and 5637 cells (human bladder cancer cell lines) |
Preparation Method | E-J and 5637 cells were maintained in RPMI 1640 medium supplemented with 10% fetal bovine serum (FBS) at 37°C, 5% CO₂. Cells were treated with the EZH2 inhibitor UNC1999 at concentrations of 0.1, 1, 10, and 100µM for 24, 72, and 120 hours. |
Reaction Conditions | 0.1-100µM; 24-120h |
Applications | UNC1999 significantly inhibited the proliferation of bladder cancer cells in a dose- and time-dependent manner. UNC1999 induced significant apoptosis and suppressed cell migration and invasion. Mechanistically, UNC1999 reduced the phosphorylation levels of JAK2 and STAT3, indicating inhibition of the JAK2/STAT3 signaling pathway. |
| Animal experiment [2]: | |
Animal models | BALB/c nude mice |
Preparation Method | Y79 retinoblastoma cells were subcutaneously injected into the posterior flank of female BALB/c nude mice. After one week of tumor growth, mice were randomly divided into two groups. One group was treated with UNC1999 (25mg/kg, i.p.) twice a week for 3 weeks. The control group received intraperitoneal injections of vehicle (5% DMSO in corn oil). Tumor volume was measured three times per week. Mice were sacrificed after 4 weeks, and tumors were collected for further analysis. |
Dosage form | 25mg/kg; i.p.; Twice per week for 3 weeks |
Applications | UNC1999 administration significantly inhibited the growth of retinoblastoma xenograft tumors in vivo compared to the vehicle control. UNC1999 treatment reduced the protein levels of EZH2 and phosphorylated STAT3 (pY-STAT3) while increasing the expression of FoxO1 in the excised tumors. |
