Re-design and evaluation of diclofenac-based carborane-substituted prodrugs and their anti-cancer potential [PDF]
In this study, we investigated a novel anti-cancer drug design approach by revisiting diclofenac-based carborane-substituted prodrugs. The redesigned compounds combine the robust carborane scaffold with the oxindole framework, resulting in four carborane-
