• molecule to investigate Hsp90 biology, and in fact the attachment of GM to solid support enabled the identification of Hsp90 as the target of its anticancer activity through affinity purification [16]. Biotinylated GM has also been synthesized and has been proposed as a tool to identify proteins other than

• rosamines can confer selective anticancer activity both in vitro and in vivo in animal models [13]. Under nontoxic conditions, rhodamines and mitochondria-targeted fluorescent proteins have been extensively used for imaging and analysis of these organelles in cell culture, enabling studies of dynamic fusion

• the anticancer activity, by focusing on the drug/receptor interaction. Vinblastine and vincristine are “dimeric” molecules, comprising two subunits, i.e., rearranged (+)-catharanthine (T) and (−)-vindoline (D) (Figure 4) [48]. The gas-phase ligand-displacement approach was employed to investigate the

• while the half-disc-shaped curcuminoids (B in Figure 2) self-assemble with the formation of columnar mesophases. Moreover, the presence of biologicaly active fragments (the O,O chelating ligands) induces promising anticancer activity in vitro against two human prostatic cancer cell lines in all these

Although the inhibitor combinations are thought to be effective because they interfere with chromosome separation by two separate microtubule-related mechanisms, there is also evidence that another mechanism of synergy may exist (see Discussion).
