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.

Abstract Background The discovery of epidermal growth factor receptor (EGFR) inhibitors for the treatment of lung cancer, most especially non-small cell lung cancer (NSCLC), was one of the major challenges encountered by the medicinal chemist in the world. The treatment of EGFR tyrosine kinase to manage NSCLCs becomes an urgent therapeutic necessity. NSCLC was the foremost cause of cancer mortality worldwide. Therefore, there is a need to develop more EGFR inhibitors due to the development of drug resistance by the mutation. This research is aimed at designing new EGFR inhibitors using a structure-based design approach. Structure-based drug design comprises several steps such as protein structure retrieval and preparation, ligand library preparation, docking, and structural modification on the best hit compound to design new ones. Result Molecular docking virtual screening on fifty sets of quinazoline derivatives/epidermal growth factor receptor inhibitors against their target protein (EGFR tyrosine kinase receptor PDB entry: 3IKA) and pharmacokinetic profile predictions were performed to identify hit compounds with promising affinities toward their target and good pharmacokinetic profiles. The hit compounds identified were compound 6 with a binding affinity of − 9.3 kcal/mol, compounds 5 and 8, each with a binding affinity of − 9.1 kcal/mol, respectively. The three hit compounds bound to EGFR tyrosine kinase receptor via four different types of interactions which include conventional hydrogen bond, carbon-hydrogen bond, electrostatic, and hydrophobic interactions, respectively. The best hit (compound 6) among the 3 hit compounds was retained as a template and used to design sixteen new EGFR inhibitors. The sixteen newly designed compounds were also docked into the active site of EGFR tyrosine kinase receptor to study their mode of interactions with the receptor. The binding affinities of these newly designed compounds range from − 9.5 kcal/mol to − 10.2 kcal/mol. The pharmacokinetic profile predictions of these newly designed compounds were further examined and found to be orally bioavailable with good absorption, low toxicity level, and permeable properties. Conclusion The sixteen newly designed EGFR inhibitors were found to have better binding affinities than the template used in the designing process and afatinib the positive control (an FDA approved EGFR inhibitor). None of these designed compounds was found to violate more than the permissible limit set by RO5. More so, the newly designed compounds were found to have good synthetic accessibility which indicates that these newly designed compounds can be easily synthesized in the laboratory.

The article is an overview and contains up-to-date information on the use of tetracycline antibiotics in the prevention of acne-like rash in patients receiving therapy with epidermal growth factor receptor inhibitors. According to studies, prevention of skin toxicity is necessary to maintain the effectiveness of the antitumor effect of EGFR inhibitors and to minimize the negative effect of adverse effects from the skin on the quality of life of patients. The use of tetracycline antibiotics in combination with topical therapy and photoprotection for the prevention of acne-like rash against the background of the use of EGFR inhibitors is a fairly safe method for long-term use. Of the antibacterial drugs for the prevention of acne-like rash, the most advisable is the appointment of doxycycline at a dose of 100 mg per day from the first day of taking EGFR inhibitors.

It is presumed that antiproliferative activity of anthocyanidin has interaction with Epidermal Growth Factor Receptor (EGFR) which has effect on lung cancer cell growth. This study aimed to observe the interaction between anthocyanidin and EGFR and to find out prediction, absorption, distribution activities as well as anthocyanidin toxicity compared to Gefitinib, an EGFR inhibitor. All test compounds were optimized with Autodock Tools®, then molecular docking simulations and predictions of absorption, distribution and toxicity were carried out. Malvidin was stated to meet the Lipinski's Rule of Five, indicating good bioavailability. Result of molecular docking simulation showed that malvidin had better affinity against EGFR than Gefitinib. Molecular docking visualization result showed that malvidin had interaction with amino acid residue such as Met793, Gln791, Leu718, Thr854, Asp855 and Lys745. Absorption and distribution predictions included percentage scores of Human Intestinal Absorption (HIA), human colon adenocarcinoma (Caco-2), and Plasma Protein Binding. Toxicity test revealed that malvidin was mutagenic compound but not carcinogenic one. The findings indicated that malvidin was potential to be an anti lung cancer candidate through EGFR inhibition.Keywords: Antiproliferative, Anthocyanidin, Epidermal Growth Factor Receptor, Molecular Docking
