Taccalonolide E (5 or 10 μM; 18 h) causes an increased density of cellular microtubules in interphase cells and the formation of thick bundles of microtubules in A-10 cells[1].
Taccalonolide E (1 or 5 μM; 18 h) causes the appearance of abnormal multipolar mitotic spindles in A-10 and HeLa cells[1].
Taccalonolide E (5 μM; 6-24 h) arrests cell cycle at G2-M phase[1].
Taccalonolide E (0.5-5 μM; 18 h) initiates micronucleation in interphase A-10 cells[1].
Taccalonolide E (48 h) inhibits cancer cell proliferation[1].
Taccalonolide E (10 μM; 1 h) causes polymerization of tubulin in MDA-MB-435 cells[1].
Taccalonolide E (5 μM; 4-30 h) initiates Bcl-2 phosphorylation, MAPK activation, and apoptosis[1].
