This study aimed at evaluating the antiproliferative, antibacterial, and anti-inflammatory properties of an ethanolic myrtle extract (Myrtacine®) in vitro, characterising its potential active compounds (myrtucommulones A and B') by structural analysis, and evaluating their biological activity. Antiproliferative activity was assessed by the BrdU incorporation assay in HaCat keratinocytes and inh...

The pharmacokinetics and metabolism of Navelbine (NVB) were investigated in 20 patients by a specific high performance liquid chromatographic methodology allowing the monitoring of NVB, deacetyl-NVB, and N-oxide NVB. After the i.v. (15 min) administration of 30 mg/m2 of drug, blood and urine samples were collected for, respectively, 144 and 48 h. NVB is characterized by a three compartmental ki...

Chemical compounds that interfere with microtubules such as the vinca alkaloids and taxanes are important chemotherapeutic agents for the treatment of cancer. As our knowledge of microtubule-targeting drugs increases, we realize that the mechanism underlying the anti-cancer activity of these agents may mainly lie in their inhibitory effects on spindle microtubule dynamics, rather than in their ...

PURPOSE Vinorelbine (Navelbine) is an orally absorbable Vinca with broad antitumor activity. It differs from other Vinca in that it is structurally modified on the catharanthine nucleus and has differential actions on tubulin that render it less neurotoxic than other compounds in this class. We conducted a phase I study of vinorelbine given the activity of Vinca alkaloids in many pediatric tumo...

Aberrant expression of beta-tubulin isotypes is frequently described in tumor tissues and tubulin-binding agent (TBA)-resistant cell lines. There is limited understanding of the role of specific beta-tubulin isotypes in cellular sensitivity to TBAs, and to gain insights into the functional role of betaII- and betaIVb-tubulin, we examined these isotypes in lung cancer cell lines NCI-H460 (H460) ...
