NPPB and neoplasm: In an in vitro model using poly-lysine-coated glass slides, pre-incubation of Epothilone B/BNP on the slide surface significantly reduced suppressed tumor adhesion and growth compared with free Epothilone B at the same dosage in subsequent incubation with USC cells, even though the cytotoxicity of free Epothilone B is higher than Epothilone B/BNP in equivalent dose.
