Abstract:
The identification of targetable molecules in cellular signaling pathways represents a milestone in the treatment of melanoma. Selective inhibitors of these molecules, known as phosphokinases, allow for individual signaling pathways to be "switched off". This is of particular importance for tumors in which these pathways are constitutively activated by mutations in genes encoding said molecules. Especially patients with BRAF-mutated melanomas significantly benefit from kinase inhibitor therapies, with the current standard of combined BRAF and MEK inhibition providing very good long-term disease control. Such regimens have been shown to achieve a progression-free survival of more than ten months and an overall survival of more than two years, along with good quality of life. Given that the majority of patients develop secondary resistance during long-term kinase inhibitor therapy, current clinical trials are geared towards finding suitable drug combinations including inhibitors of other signaling pathways as well as immune checkpoint inhibitors. The present review highlights targeted therapies for melanoma currently available as well as potential future options presently under clinical investigation.

Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
