MELK-8a
Based on 3 publication(s) in Google Scholar
MELK-8a (NVS-MELK8a) is a highly potent and selective maternal embryonic leucine zipper kinase (MELK) inhibitor with IC50 of 2 nM. MELK-8a also inhibits Flt3 (ITD), Haspin, PDGFRα with IC50s of 0.18, 0.19, and 0.42 μM, respectively. MELK plays an essential role in regulating cell mitosis in a subset of cancer cells.

Mass spectrometry-based selectivity profiling identifies a highly selective inhibitor of the kinase MELK that delays mitotic entry in cancer cells. [Abstract]2020 Feb 21;295(8):2359-2374. PMID: 31896573
MELK-8a purchased from MedChemExpress. Usage Cited in: J Biol Chem. 2020 Feb 21;295(8):2359-2374. [Abstract]
HeLaS3 cells treated with 8a complete mitosis and begin the subsequent cell cycle following delayed mitotic entry. HeLaS3 cells are synchronized at G1/S with double thymidine block and released into DMSO or 3 μM 8a. Cells are collected starting at 6h post-release, with subsequent collections completed every 2h over a 20h timecourse. Cells are lysed and immunoblotted with the indicated antibodies. The split in the image indicates that the samples from DMSO and 3 μM 8a conditions are blotted sepa

Delayed mitotic entry caused by 8a is associated with delayed activation of Aurora A, Aurora B, and CDK1. HeLaS3 cells are synchronized at G1/S with double thymidine block and released into DMSO or 3 μM 8a. Cells are collected starting at 6h post-release, with subsequent collections completed every 0.5 or 1h, over a 12h timecourse. Cells are lysed and immunoblotted with the indicated antibodies. The split in the image indicates that the samples from DMSO and 3 μM 8a conditions are blotted sepa.

MELK inhibition with 3 μM 8a causes delayed mitotic entry. HeLaS3 cells are synchronized at G1/S with double thymidine block and released into DMSO, 1 μM, or 3 μM 8a. Cells are collected every 2h over a 12h timecourse. Cells are lysed and immunoblotted with the indicated antibodies. The splits in the image indicate that the samples from DMSO, 1 μM, and 3 μM 8a conditions are immunoblotted separately due to space constraints. Asynchronous HeLaS3 lysate is loaded in the lanes labeled “A” in order
