| In vitro | Cemadotin (0-1 μM) significantly enhances the frequency of rescue while exerting minimal impact on the occurrence of catastrophes.[1] Cemadotin (0-100 μM ; 35 min) demonstrates a dose-dependent inhibition of polymerization in Tubulin-treated Strongylocentrotus purpuratus.[1] Cemadotin (0-1000 nM) selectively suppresses the rate and magnitude of tubulin growth excursions, with suppression correlating to drug concentration.[1] Cemadotin (400 pM~300 nM ; 72 h) inhibits the viability of HEK 293, F9, and HL60 cancer cells.[2] |
