Actividad biológica
ProTAME prevents anaphase entry in mouse and bovine oocytes and also in mouse 2-cell embryos. proTAME (0-100 μM ) treatment shows dose-dependent metaphase arrest in mammalian oocytes and early cleavage embryos. And the metaphase arrest induced by this drug does not require spindle assembly checkpoint (SAC) activity[1].
ProTAME arrest of meiosis I in mouse oocytes is due to the inhibition of APC/C. In contrast to the somatic cells, the arrest in oocytes and embryos is not reversible[1].
proTAME (0-20 μM) dose-dependently affects morphological parameters of the spindle in oocytes and in embryos[1].
proTAME is efficient in overcoming resistance caused by the hyperphosphorylation of CDH1 in glioblastoma cells, polo-like kinase 1 (PLK1)-based drug resistance in ovarian cancer cells and CDC20-based resistance in diffuse large B-cell lymphoma[1].
proTAME inhibits OVCAR-3 cells growth with an IC50 of 12.5 μM[2].

Preventing internal positioning reduces the risk of premature chromosome separation. 3D-reconstructed images of chromosomes (H2B-SNAP, white), NDC80-NUF2 beads (NDC80-sfGFP, green), and prematurely separated chromosomes (magenta) in proTAME (2.5 μM)-treated aged oocytes. Oocytes were monitored for premature chromosome separation by live imaging for 37 hours. In the plot, each spot corresponds to the data from one experiment. Bars indicate the percentage of oocytes that exhibited premature chromosome separation in four independent experiments. The number of oocytes is shown in parentheses. scale bars, 5 μm (for magnified images, 1.5 μm).

proTAME purchased from MedChemExpress. Usage Cited in: Science. 2024 Jun 7;384(6700):eadk0775. [Abstract]
Immunoblot analysis of APC/C target proteins securin and cyclin B1 as well as ERK activity readouts pERK and pRSK following treatment with proTAME (APC/Ci) (5-10 μM; 24 h) and/or ERKi in Pa16C cells. The results showed that proTAME was verified to prevent the reduction in protein levels of securin and cyclin B1 caused by 24-hour treatment with ERKi.
