proTAME, a cell-permeable prodrug form of TAME, is an anaphase promoting complex/cyclosome (APC/C) inhibitor. proTAME causes cell cycle arrest in metaphase[1][2].

In Vitro

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].
