Meisoindigo (Dian III) 是 Indirubin (HY-N0117) 的衍生物，可以造成急性髓细胞性白血病 (AML) 细胞周期在 G0/G1 期停滞，并诱导凋亡。Meisoindigo 具有很高的抗肿瘤活性。
| 生物活性 | Meisoindigo (Dian III), a derivative of Indirubin (HY-N0117), halts the cell cycle at the G0/G1 phase and inducesapoptosisin primary acute myeloid leukemia (AML) cells. Meisoindigo exhibits high antitumor activity[1][2]. |
体外研究
(In Vitro) | Meisoindigo (Dian III; 5-20 μM; for 24 hours) inhibits growth of the AML cell lines[1].
Meisoindigo (10 μM; for 24 hours) induces apoptosis of acute myeloid leukemia[1].
Meisoindigo (5-10 μM; for 24 hours) causes cell-cycle arrest[1].
Meisoindigo (5-10 μM; for 24 hours) increases the cleaved caspase-3 and pro-apoptotic Bak, and decreases Bcl-2 and Bcl-xL levels in HL-60 cells[1].
Meisoindigo (10, 30, 50, 100, 150 μM; 24 hours) interdicts LPS-induced (1 μg/mL) NLRP3 inflammasome activation and M1/M2 polarization through down-regulation of TLR4 pathways after OGD/R in HT-22 and BV2 cells[2].
Cell Viability Assay[1] | Cell Line: | HL-60, NB4, U937 leukemic cell lines | | Concentration: | 5, 10, 15, 20 μM | | Incubation Time: | For 24 hours | | Result: | Inhibited growth of the AML cell lines in a dose- and time-dependent manner. |
Apoptosis Analysis[1] | Cell Line: | HL-60 cells | | Concentration: | 10 μM | | Incubation Time: | For 24 hours | | Result: | Induced apoptosis of acute myeloid leukemia. |
Cell Cycle Analysis[1] | Cell Line: | HL-60 cells | | Concentration: | 5, 10 μM | | Incubation Time: | For 24 hours | | Result: | Caused cell-cycle arrest, with more cells in sub-G1 and G0/G1 phases and fewer cells in the S phase, in a dose-dependent manner. |
Western Blot Analysis[1] | Cell Line: | HL-60 cells | | Concentration: | 5, 10 μM | | Incubation Time: | For 24 hours | | Result: | Increased the cleaved caspase-3 and pro-apoptotic Bak, and decreased Bcl-2 and Bcl-xL levels in HL-60 cells. |

体内研究
(In Vivo) | Meisoindigo (Dian III; 50-150 mg/kg; IP; daily; for 14 days) has anti-leukemic activity in vivo[1].
Meisoindigo (2, 4, 8, 12 mg/kg; IP; before MCAO and 2 h after reperfusion) significantly reduces infarct volume, ameliorates neurological deficits 3 days after middle cerebral artery occlusion (MCAO) in Wild-type C57BL/6J mice (25-30 g). Meisoindigo reduces edema and lowers AQP4 expression in the brain[2].
| Animal Model: | NOD/SCID mice, 6-8 weeks old, with HL-60 leukemic cells[1] | | Dosage: | 50, 100, 150 mg/kg | | Administration: | IP; daily; for 14 days | | Result: | Had anti-leukemic activity in vivo. |
