Abstract:
Melanoma is the most dangerous skin malignancy due to its strong metastatic potential with high mortality. Activation of crucial signaling pathways enforcing melanoma progression depends on phosphorylation of distinct tyrosine kinases and oxidative stress. We here investigated the effect of a bis-coumarin derivative [3, 3'- ((3″, 5'-Dichlorophenyl) methylene) bis (4-hydroxy-2H-chromen-2-one)] [3, 3'- (3, 5-DCPBC)] on human melanoma cell survival, growth, proliferation, migration, intracellular redox state, and deciphered associated signaling pathways. This derivative is toxic for melanoma cells and non-toxic for melanocytes, their benign counterpart, and fibroblasts. 3, 3'- (3, 5-DCPBC) inhibits cell survival, migration, and proliferation of different metastatic and non-metastatic melanoma cell lines through profound suppression of the phosphorylation of Epidermal Growth Factor receptor (EGFR) and proto-oncogene cellular sarcoma (c-SRC) related downstream pathways. Thus, 3, 3'- (3, 5-DCPBC) endowed with the unique property to simultaneously suppress phosphorylation of multiple downstream kinases, such as EGFR/JAK/STAT and EGFR/SRC and their corresponding transcription factors.

Main Methods:
- Treatment of human melanoma cell lines, melanocytes, and fibroblasts with 3,3'-(3,5-DCPBC).
- Assessment of cell survival, growth, proliferation, and migration.
- Analysis of intracellular redox state and key signaling pathway phosphorylation (EGFR, c-SRC, JAK/STAT).
Main Results:
- 3,3'-(3,5-DCPBC) demonstrated selective toxicity towards melanoma cells, sparing melanocytes and fibroblasts.
- The derivative significantly inhibited melanoma cell survival, migration, and proliferation across various cell lines.
- 3,3'-(3,5-DCPBC) profoundly suppressed the phosphorylation of Epidermal Growth Factor receptor (EGFR) and c-SRC, impacting downstream pathways like JAK/STAT.
Conclusions:
- The bis-coumarin derivative 3,3'-(3,5-DCPBC) exhibits potent anti-melanoma activity.
- This compound selectively targets melanoma cells and inhibits critical pro-survival and pro-metastatic signaling pathways.
- 3,3'-(3,5-DCPBC) represents a promising therapeutic agent for melanoma by simultaneously suppressing multiple kinase pathways.
