Biological Activity

Epothilone B shows better activity than Epothilone A. The EC0.01 of Epothilone B is 1.8 μM. Epothilone B potently inhibits cell proliferation in HCT116 cells, with IC50 of 0.8 nM.Epothilone B induces mitotic arrest and displays cytotoxicity in KB3-1, KBV-1, Hela, and Hs578T cells, with IC50 of 3 nM to 92 nM. Epothilone B competes with Taxol in binding to microtubules, with IC50 of 3.3 μM. In MCF-7 cells overexpressing GFP-α-tubulin, Epothilone B (3.5 nM) efficiently blocks microtubule dynamics. Meanwhile, Epothilone B induces mitotic arrest with IC50 of 3.5 nM. In multiple myeloma (MM) cells, including RPMI 8226, U266, MM.1S, LR5, and MR20, Epothilone B directly suppresses proliferation with IC50 of 1 nM to 10 nM. Similarly, Epothilone B (10 nM) also induces cell cycle arrest and apoptosis.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
