Popis: | Novel second generation analogs of eribulin mesylate, a tubulin agent recently approved for the treatment of breast cancer, are reported. Our recent efforts have focused on expanding the target indications for this class of compounds to other tumor types. Herein, we describe the design, synthesis and evaluation of eribulin analogs active against brain tumor cell lines in vitro and corresponding brain tumor models in mice. Attenuation of basicity of the amino group(s) in the C32 side-chain region led to compounds with lower susceptibility to P-gp mediated drug efflux, allowing these compounds to permeate through the blood-brain barrier. In preclinical in vivo studies, these compounds showed significantly higher levels in the brain and cerebrospinal fluid as compared to eribulin. In addition, analogs within this series showed antitumor activity in an orthotopic murine model of human glioblastoma. |
