Les-6666
Les-6666 is a β-tubulin inhibitor. Les-6666 exerts antiproliferative, pro-apoptotic, cell cycle arrest and migration-inhibitory effects, and suppresses DNA synthesis. Les-6666 can be used in the research of pancreatic cancer.

Les-6666 potently inhibits the growth of the NCI-60 human tumor cell line panel with a mean GI50 of 0.056 μM, and shows particularly strong activity against K-562, SR, NCI-H522, and MDA-MB-435 cell lines[1].
Les-6666 (0.001-10 μM; 24-72 h) exhibits potent cytotoxicity against multiple cancer cell lines, with the strongest activity against MIA PaCa-2 pancreatic cancer cells (IC50 = 0.08 μM at 72 h), and shows lower toxicity against normal Beas-2B and HDFa cells[1].
Les-6666 (0.1-1 μM; 48 h) inhibits DNA synthesis and proliferation of MIA PaCa-2 pancreatic cancer cells, reducing [3H]-thymidine incorporation to 35-44% of control levels after 48 h of treatment at 0.1-1 μM[1].
Les-6666 (0.1-1 μM; 48 h) potently suppresses clonogenic survival of MIA PaCa-2 pancreatic cancer cells, reducing the surviving fraction to less than 3% after 48 h of treatment at 0.1-1 μM[1].
Les-6666 (0.1-0.5 μM; 24-48 h) strongly inhibits migration of MIA PaCa-2 pancreatic cancer cells, limiting gap closure to 4.7-10.7% after 24-48 h of treatment at 0.1-0.5 μM[1].
Les-6666 (0.1-0.5 μM; 48 h) induces significant early and late apoptosis in MIA PaCa-2 pancreatic cancer cells, with combined apoptotic populations reaching over 74% after 48 h of treatment at 0.1-0.5 μM[1].
Les-6666 (0.1-0.5 μM; 48 h) arrests MIA PaCa-2 pancreatic cancer cells in the G2/M phase of the cell cycle, increasing the G2/M population to over 33% after 48 h of treatment at 0.1-0.5 μM[1].
Les-6666 (0.1-0.5 μM; 48 h) reduces β-tubulin protein concentration in MIA PaCa-2 pancreatic cancer cells, lowering levels to ~50% of control after 48 h of treatment at 0.1-0.5 μM[1].
Les-6666 (0.1-0.5 μM; 48 h) reduces βIII-tubulin protein expression in MIA PaCa-2 pancreatic cancer cells, lowering levels to 71.7-78.7% of control after 48 h of treatment at 0.1-0.5 μM[1].
