DHI1
DHI1 is an anti-leukemia agent with high selectivity for Jurkat (IC50 = 21.83 μM) and HL-60 (IC50 = 19.14 μM) leukemia cells and has low toxicity to non-cancerous cells. DHI1 can induce G2/M phase cell arrest in Jurkat and HL-60 leukemia cells, as well as S phase arrest in HL-60 cells, and has significant effects on cell cycle signaling molecules Wee1, cyclin B1, cdc2 on Tyr15, and Chk1. DHI1 inhibits the migration and invasion of Jurkat and HL-60 cells by disrupting cytoskeletal actin filaments. DHI1 can be used to study hematological malignancies.

Biological Activity
|
Chk1 |
DHI1 (Compound 4a) (3-100 μM, 24-72 h) shows inhibitory viability against Jurkat and HL-60 cells, with IC50s of 21.83 and 19.14 μM, but has weak inhibitory viability against HCT-116, HeLa, MCF-7, U87,Hep G2, A549, A2780, BJ-5ta, MCF-10A cells[1].
DHI1 (19.14-21.83 μM, 24-72 h) induces cell cycle arrest at G2/M phase and affects signaling proteins related to the cell cycle in Jurkat and HL-60 cells[1].
DHI1 (10-40 μM, 3 h) decreases chemotaxis and invasiveness of Jurkat and HL-60 leukemic cells[1].
DHI1 (19.14-21.83 μM, 24-72 h) induces disruption, disorganization, damage to F-actin structures and nuclear fragmentation and membrane blebbing, impacts cytoskeleton of Jurkat and HL-60 leukemic cells[1].
DHI1 (3.125-100 μM, 24 h) enhances PBMC cell viability[1].
