NMR Spectroscopic Data of Marine-Derived Bisindole Calcicamide A and Its Analogs as Potential Anti-Breast Cancer Stemness Agents

This dataset encompasses nuclear magnetic resonance (NMR) spectroscopic data (¹H NMR, ¹³C NMR, and additional ¹⁹F NMR for fluorine-containing analogs XQ-29, XQ-30, XQ-58, XQ-59, XQ-61) of marine-derived bisindole Calcicamide A and its synthetic analogs, providing critical structural characterization and purity confirmation for pharmacological research, structure-activity relationship (SAR) analysis, and targeted anti-cancer drug development.
