Inappropriate activation of the Epidermal growth factor receptor (EGFR) group of kinases has been identified in a variety of tumour cells, either due to mutation or overexpression. Although the tumour is a fatal disease, significant therapy discoveries have lately been made. The human EGFR and this family of kinases have emerged as promising targets for cancer therapy. In this molecular docking study, Natural marine toxins are employed to regulate the activity of the human EGFR tyrosine kinase domain (EGFRtkd) in the molecular docking investigation (PDB ID5JEB). Marine biotoxins can cause neurological, gastrointestinal, and cardiovascular problems, as well as severe mortality and long-term morbidity in some situations. Because there is no antidote for any of the natural marine poisons, supportive care is the mainstay of treatment. Paralytic shellfish poisoning, in particular, and puffer fish poisoning, in particular, can result in death within hours of exposure to the poisons and may require immediate medical intervention. However, this research found that marine biotoxins can modulate EGFRtkd. Furthermore, homoyessotoxin was anticipated to be an EGFRtkd modulator with a binding affinity as -9.584 kcal/mol. To employ the homoyessotoxin in tumour therapies, further knowledge of natural marine biotoxins and further toxicological research is required.

Cancer is the world’s second leading cause of death, accounting for nearly 10 million deaths and 19.3 million new cases in 2020. Curcumin analogs are gaining popularity as anticancer agents currently. We reported herein the isolation, molecular engineering, molecular docking, antiproliferative, and anti-epidermal growth factor receptor (anti-EGFR) activities of curcumin analogs. Three curcumin analogs were prepared and docked against the epidermal growth factor receptor (EGFR), revealing efficient binding. Antiproliferative activity against 60 NCI cancer cell lines was assessed using National Cancer Institute (NCI US) protocols. The compound 3b,c demonstrated promising antiproliferative activity in single dose (at 10 µM) as well as five dose (0.01, 0.10, 1.00, 10, and 100 µM). Compound 3c inhibited leukemia cancer panel better than other cancer panels with growth inhibition of 50% (GI50) values ranging from 1.48 to 2.73 µM, and the most promising inhibition with GI50 of 1.25 µM was observed against leukemia cell line SR, while the least inhibition was found against non-small lung cancer cell line NCI-H226 with GI50 value of 7.29 µM. Compounds 3b,c demonstrated superior antiproliferative activity than curcumin and gefitinib. In molecular docking, compound 3c had the most significant interaction with four H-bonds and three π–π stacking, and compound 3c was found to moderately inhibit EGFR. The curcumin analogs discovered in this study have the potential to accelerate the anticancer drug discovery program.
