MLN0905
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].
