MLN0905 Usage And Synthesis

Biological Activity

mln0905 is a potent inhibitor of plk1 with ic50 value ranges from 3 to 24 nm [1].polo-like kinase 1 (plk1) is a family of conserved serine/threonine kinases and plays an important role in regulating cell cycle. it has been revealed that plk1 drives cell cycle progression by triggerting g2/m transition and is considered as a pro-oncogene which overexpressed in tumor cells [2].mln0905 is a selective plk1 inhibitor and has similar effect as rnai hnockdown. when tested with ht-29 cells, mln0905 treatment significantly increased phish3 expression which indicated that cells were arrested in g2/m phase by inhibiting plk1 expression [1].in mouse model with human diffuse large b-cell lymphoma (dlbcl) cell line ocily-19 subcutaneous xenograft, co-administration of mln0905 and rituximab markedly reduced tumor volume and increased survival time through inhibiting plk1 which resulted in mitotic arrest [1]. and the same result was achieved when using nude mice model with human colon tumor ht29 xenograft, mln0905 treatment significantly inhibited tumor growth or progression [3].
