Article excerpt:
"...we showed that OS cell lines overexpressing ABCB1 and ABCC1 were also crossresistant to vinorelbine, taxotere (docetaxel) and etoposide. Combined treatments with CBT-1 and these three drugs produced some relevant chemosensitization effects, indicating that CBT-1 can increase cellular sensitivity also to some of the agents used in second-line OS treatments, which are ABCB1 and/or ABCC1 substrates. Therefore, drugs which, as CBT-1, target or inhibit these transporters, may significantly enhance the moderate efficacy of the presently used rescue protocols.
Moreover, it has recently been shown that targeting specific protein kinases with tyrosine kinase inhibitors represent an interesting new therapeutic option for OS treatment [5, 6, 38-40]. However, it has to be taken into account that several tyrosine kinase inhibitors are ABC substrates [41-43]. Therefore, CBT-1 treatment may also be considered to increase sensitivity to these drugs in ABC overexpressing patients."
