abstract = "The presence of inflammatory mediators in the tumor microenvironment,
such as cytokines, growth factors or eicosanoids,
indicate cancer-related inflammatory processes. Targeting these
inflammatory mediators and related signal pathways may offer
a rational strategy for the treatment of cancer. This study
focuses on the incorporation of metabolically stable, sterically
demanding, and hydrophobic dicarba-closo-dodecaboranes
(carboranes) into dual cyclooxygenase-2 (COX-2)/5-lipoxygenase
(5-LO) inhibitors that are key enzymes in the biosynthesis
of eicosanoids. The di-tert-butylphenol derivative tebufelone
represents a selective dual COX-2/5-LO inhibitor. The incorporation
of meta- or para-carborane into the tebufelone scaffold
resulted in eight carborane-based tebufelone analogs that
show no COX inhibition but 5-LO inhibitory activity in vitro. Cell
viability studies on HT29 colon adenocarcinoma cells revealed
that the observed antiproliferative effect of the para-carborane
analogs of tebufelone is enhanced by structural modifications
that include chain elongation in combination with introduction
of a methylene spacer resulting in higher anticancer activity
compared to tebufelone. Hence, this strategy proved to be a
promising approach to design potent 5-LO inhibitors with
potential application as cytostatic agents.",
