Cancer-Curative Potential of Novel Coumarins From Watermelon Princess: A Scenario of Their Isolation and Activity

In this research, different types of solvents were used to isolate coumarins from the seeds of watermelon princess, including acetone, ether, chloroform, and dichloromethane. isolation is accomplished by utilizing three approaches: thermodynamic-, ultrasound-, and microwave-corroborative extractions. these approaches are done in three modalities: non-sequential, sequential rising polarity, and sequential dropping polarity. based on the findings gathered from the phytoconstituents’ assessments, one of the thirty isolates was selected to identify its content of coumarins. six novel fruit-derived natural coumarins, abbreviated here as re1-re6, have been identified, and their respective molecular backbones are deduced by comparing their spectral data and physical attributes to those previously published. these natural coumarins were tested in vitro for two biopotentials. the first is oxidation-protective potential, which was measured by evaluating the ability of our natural coumarins to ambush hydroxyl and dpph drastic brands. the second is cancer-curative potential, which was investigated via a mtt test against six cancer cell lines. besides, the undamaging effect of these coumarins on normal cells was investigated using one healthy cell line. from the findings, the authors concluded that product re4 could provide a valuable structural template for synthesizing a potent oxidation-protective agent with significant safety. furthermore, product re6 can serve as a foundation stone for the development of potent cancer-curing medications with minimal toxicity to normal tissue.
