Abstract
One of the cost-effective alternative methods to find new inhibitors has been the repositioning approach of existing drugs. The advantage of computational drug repositioning method is saving time and cost to remove the pre-clinical step and accelerate the drug discovery process. Hence, an ensemble computational-experimental approach, consisting of three steps, a machine learning model, simulation of drug-target interaction and experimental characterization, was developed. The machine learning type used here was a different tree classification method, which is one of the best randomize machine learning model to identify potential inhibitors from weak inhibitors. This model was trained more than one-hundred times, and forty top trained models were extracted for the drug repositioning step. The machine learning step aimed to discover the approved drugs with the highest possible success rate in the experimental step. Therefore, among all the identified molecules with more than 0.9 probability in more than 70% of the models, nine compounds, were selected. Besides, out of the nine chosen drugs, seven compounds have been confirmed to inhibit EGF in the published articles since 2019. Hence, two identified compounds, in addition to gefitinib, as a positive control, five weak-inhibitors and one neutral, were considered via molecular docking study. Finally, the eight proposed drugs, including gefitinib, were investigated using MTT assay and In-Cell ELISA to characterize the drugs' effect on A431 cell growth and EGF-signaling. From our experiments, we could conclude that salicylic acid and piperazine could play an EGF-inhibitor role like gefitinib.

Abstract
Salicylanilides are pharmacologically active compounds with a wide spectrum of biological effects. Halogenated salicylanilides, which have been used for decades in human and veterinary medicine as anthelmintics, have recently emerged as candidates for drug repurposing in oncology. The most prominent example of salicylanilide anthelmintic, that is intensively studied for its potential anticancer properties, is niclosamide. Nevertheless, recent studies have discovered extensive anticancer potential in a number of other salicylanilides. This potential of their anticancer action is mediated most likely by diverse mechanisms of action such as uncoupling of oxidative phosphorylation, inhibition of protein tyrosine kinase epidermal growth factor receptor, modulation of different signaling pathways as Wnt/β-catenin, mTORC1, STAT3, NF-κB and Notch signaling pathways or induction of B-Raf V600E inhibition. Here we provide a comprehensive overview of the current knowledge about the proposed mechanisms of action of anticancer activity of salicylanilides based on preclinical in vitro and in vivo studies, or structural requirements for such an activity.

Abstract
The present study aimed to investigate the effects of a gefitinib derivative, LPY-9, on the proliferation, apoptosis and migration of human glioma cell line U251-MG by CCK8, Transwell or flow cytometry, and the effect of LPY-9 on the activity of caspase-3 enzyme and related proteins in the vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) pathways by western blot and ELISA. It was found that LPY-9 exhibited higher a inhibitory effect on the proliferation of U251-MG cell lines compared with gefitinib and it also exhibited a certain dose-dependence. Following LPY-9 treatment, typical apoptotic morphology was observed under the microscope after Giemsa staining. LPY-9 induced apoptosis at low concentration, and the activity of caspase-3 enzyme increased with the increase in drug concentration, significantly inhibiting the secretion of VEGF in a dose-dependent manner. The effect was notably more evident compared with gefitinib at the same concentration. The expression level of caspase-3 and cleaved caspase-3 increased with the increase in LPY-9 concentration; however, expression levels of VEGF, EGFR, phosphorylated AKT and PI3K decreased with the increase of LPY-9 concentration and no change was observed in the expression level of AKT. LPY-9 inhibited the proliferation of the human glioma cell line U251-MG, promoted apoptosis and effectively inhibited the migration of U251-MG cells. The effect of LPY-9 was more noticeable compared with gefitinib. The results of the present study may provide a foundation for further study and clinical research of this as an anti-tumor drug in animal models.

Ring-Substituted 1-Hydroxynaphthalene-2-Carboxanilides Inhibit Proliferation and Trigger Mitochondria-Mediated Apoptosis. Int J Mol Sci 2020; 21:ijms21103416.

Abstract
Ring-substituted 1-hydroxynaphthalene-2-carboxanilides were previously investigated for their antimycobacterial properties. In our study, we have shown their antiproliferative and cell death-inducing effects in cancer cell lines. Cell proliferation and viability were assessed by WST-1 assay and a dye exclusion test, respectively. Cell cycle distribution, phosphatidylserine externalization, levels of reactive oxygen or nitrogen species (RONS), mitochondrial membrane depolarization, and release of cytochrome c were estimated by flow cytometry. Levels of regulatory proteins were determined by Western blotting. Our data suggest that the ability to inhibit the proliferation of THP-1 or MCF-7 cells might be referred to meta- or para-substituted derivatives with electron-withdrawing groups -F, -Br, or -CF3 at anilide moiety. This effect was accompanied by accumulation of cells in G1 phase. Compound 10 also induced apoptosis in THP-1 cells in association with a loss of mitochondrial membrane potential and production of mitochondrial superoxide. Our study provides a new insight into the action of salicylanilide derivatives, hydroxynaphthalene carboxamides, in cancer cells. Thus, their structure merits further investigation as a model moiety of new small-molecule compounds with potential anticancer properties.

Abstract
A systematic study on sulfonamide derivatives with salicylamide core is presented for possible use in pharmaceutical applications. The molecular structure of eight different compounds has been investigated by FTIR in the frequency range 4000-400 cm-1 to recognize the possible geometrical shape of the molecules needed to uniquely identify the activity of molecule in cancer cell. The electronic charge distribution of these different compounds is further illustrated by UV-Vis spectroscopy in the frequency range 190-1100 nm. The theoretical results obtained from molecular modeling calculations showed that the hydrogen bonds between the OH, CO, NH, and/or CH groups vary from one compound to the other regarding their number and bond length. This confirms the experimental FTIR results regarding the position and broadening of the OH and NH groups due to free rotation of the amide group because of changing the compounds structure by adding different groups to the last phenyl ring. The hydrogen bonds take different directions and values from one compound to the other, which seems to be the most important factor regarding the activity of these different compounds in cancer cell. Both theoretical molecular modeling calculations and FTIR experimental results have strongly evaluated the relation between the chemical structure of 5-chloro-N (4-sulfamoylbenzyl) salicylamide derivatives and their biological activities.
