Cytotoxicity and anti-small cell lung cancer potential of 3-methoxy-5-nitrosalicylaldehyde: an analog for treatment of diabetes mellitus with considerable binding affinity to α-amylase enzyme

Abstract

IntroductionAlpha-amylase inhibitors are present in plants and are thought to be produced by plants to strengthen their defenses against predators. It contains plant components, polyphenolic compounds and glycoproteins with enzymatic inhibitory activity.Material and methodsThe molecular docking investigation was accomplished as a versatile method for the evaluation of the biological activities of 3-Methoxy-5-nitrosalicylaldehyde in the presence of alpha amylase. MTT test was used on normal (HUVEC) and small cell lung cancer (SBC-3, DMS273, and DMS114) cell lines.ResultsIn this study, inhibition result of metabolic enzyme was obtained IC50: 95.14 µM. The compound exhibited a considerable binding affinity to the enzyme with a docking score of -7.676 kcal/mol. The results of the molecular docking revealed that 3-Methoxy-5-nitrosalicylaldehyde is able to construct hydrophobic contacts with crucial residues of the catalytic domain of the enzyme. According to these findings, the compound has the potential to be an inhibitor for alpha amylase. 3-Methoxy-5-Nitrosalicylaldehyde had high cell death and anti-small cell lung cancer effects against SBC-3, DMS273, and DMS114 cell lines. Among the above cell lines, the best result of anti-small cell lung cancer properties of molecule was gained in the cell line of DMS273.ConclusionsThe results of this study indicated the excellent anti-small cell lung cancer potentials of 3-Methoxy-5-Nitrosalicylaldehyde in the in vitro condition. After confirming the above results in the clinical trial researches, this formulation may be administrated for the treatment of several types of small cell lung cancer in humans.
