A new series of flurbiprofen derivatives containing thiosemicarbazide moiety (3-7)  was  synthesized from flurbiprofen as parent nucleus by  esterification, hydrazide formation, and  heating with different  aryl isothiocyanate substituents, respectively. Flurbiprofen was also treated with thiosemicarbazide in the  presence POCl3 as  a catalyst,   to produce 1,3,4 -thiadiazole -2-amine (8). Treatment of (8) with different aryl isothiocyanates  produced thiourea derivatives (9-12).  Also, the reaction of  (8)  with different benzoyl chloride substituents produced benzamide compounds (13-15). Eventually , treatment of (8)  with  ethyl acetoacetate(EAA) produced [1,3,4]thiadiazolo[3,2-a]pyrimidin-7-one (16) .The new compounds were  characterized by spectroscopic techniques :FTIR,  1HNMR, and CHNS analysis. A molecular docking  study for  the  synthesized compounds (3-16), against the Vascular Endothelial Growth Factor receptor (VEGFR-2) was applied   and  it  indicated  that compounds 4,7,13, and 15,exhibited the optimum binding energy of     -6.77, -6.12,-6.68, and -6.43 kcal/mol, respectively. Target compounds were  also assessed  for their  in vitro anticancer effects  in a cell-line study. All  of the compounds tested  showed  the most plausible anticancer activity, compared to a positive control(Sorafenib), using in vitro  MTT cytotoxic assay ,against human breast tumor (MCF-7), and normal WRL-68 cell line. The in vitro results revealed that compounds 4,5,10,11,13, and 15 exhibited the highest inhibitory activity at their IC50 concentrations, against MCF-7 cell lines, as follows (122.7,113.9,95,7. 109.1,40.32 and 112.29µg/mL, respectively. While their cytotoxic effect against normal WRL-68 cell line at  their IC50 concentrations, as follow 210.2, 181.3 ,151.7,278.7,80.28, and 236 µg/mL, respectively, therefore,  such compounds were considered more selective toward MCF-7 than normal WRL-68,and their selectivity index (SI): 1.71,1.59,1.59 ,2.55 ,1.99 , and 2.10,respectively . Among the synthesized compounds, the compound 15 was chosen to screen its effect in vitro through multi-parameter cytotoxic assay against MCF-7 breast cancer implemented in High Content Screening (ArrayScan XTI, Thermo Scientific),which  could be taken in consideration as a starting point for the  development  of new anticancer drugs

In connection with our research program concerning development of novel effective benzimidazole-based anticancer candidates, herein we describe a new unexpected synthetic route to obtain a series of 2–((imidazole/benzimidazol2–yl)thio)1–arylethanones endowed with promising anti-breast cancer and Cyclin-dependent kinase 2 (CDK2) inhibitory activities. Contrary to expectations, products for the reaction of 2–mercaptoimidazole/benzimidazole 2a,b with β–keto esters 6a–c were unambiguously assigned as 2–((imidazol/benzimidazol2–yl)thio)1–arylethanones 10a–f based on NMR spectroscopy and single-crystal X-ray crystallographic analyses. In vitro anticancer activities for herein reported imidazole/benzimidazoles 10a–f were assessed through a cell-based assay against human breast cancer T4–7D and MCF–7 cell lines. Benzimidazoles 10d–f exerted better anti-proliferative action towards T4–7D and MCF–7 cell lines than their corresponding imidazole counterparts 10a–c. Furthermore, a molecular docking study suggested CDK2 kinase as a potential enzymatic target for benzimidazoles 10d–f, and investigated their possible binding pattern and interactions within CDK2 active site. Thereafter, benzimidazoles 10d–f were in vitro examined for their CDK2 inhibitory action, where they exerted good activity. Finally, several key ADME and druglikeness properties were predicted by the SwissADME online tool. Interestingly, benzimidazoles 10d–f were found to have no violations in all druglikeness rules (Veber, Lipinski, Ghose, Muegge, and Egan). In addition, they had neither PAINS nor structural alerts (Brenks). In conclusion, benzimidazoles 10d–f demonstrated not only a promising anticancer activities but also an acceptable ADME and physicochemical properties especially benzimidazole 10e.

Abstract A new series of urea and thiourea derivatives containing benzimidazole group as potential anticancer agents have been designed and synthesized. The structures of the synthesized compounds were characterized and confirmed by spectroscopic techniques such as 1H NMR, 13C NMR, and mass spectrometry. In vitro anticancer assay against two breast cancer (BC) cell lines, MDA-MB-231ER(−)/PR(−) and MCF-7ER(+)/PR(+), revealed that the cytotoxicity of 1-(2-(1H-benzo[d]imidazol-2-ylamino)ethyl)-3-p-tolylthiourea (7b) and 4-(1H-benzo[d]imidazol-2-yl)-N-(3-chlorophenyl)piperazine-1-carboxamide (5d) were higher in MCF-7 with IC50 values of 25.8 and 48.3 µM, respectively, as compared with MDA-MB-231 cells. Furthermore, 7b and 5d were assessed for their apoptotic potential using 4′,6-diamidino-2-phenylindole, acridine orange/ethidium bromide staining, and Caspase-3/7. After incubation with MCF-7, the compounds 7b and 5d induced apoptosis through caspase-3/7 activation. In conclusion, the compounds 7b and 5d are potential candidates for inducing apoptosis in different genotypic BC cell lines.

Protein tyrosine kinases (PTKs) are the most potential therapeutic targets for cancer. Herein, we present a sound rationale for synthesis of a series of novel 2-(methylthio), 2-(substituted alkylamino), 2-(heterocyclic substituted), 2-amino, 2,4-dioxo and 2-deoxo-5-deazaalloxazine derivatives by applying structure-based drug design (SBDD) using AutoDock 4.2. Their antitumor activities against human CCRF-HSB-2, KB, MCF-7 and HeLa have been investigated in vitro. Many 5-deazaalloxazine analogs revealed high selective activities against MCF-7 tumor cell lines (IC50: 0.17–2.17 µM) over HeLa tumor cell lines (IC50 > 100 µM). Protein kinase profiling revealed that compound 3h induced multi- targets kinase inhibition including −43% against (FAK), −40% against (CDKI) and −36% against (SCR). Moreover, the Annexin-V/PI apoptotic assay elucidate that compound 3h showed 33% and potentially 140% increase in early and late apoptosis to MCF-7 cells respectively, compared to the control. The structure-activity relationship (SAR) and molecular docking study using PTK as a target enzyme for the synthesized 7-deazaalloaxazine derivatives were investigated as potential antitumor agents. The AutoDock binding affinities of the 5-deazaalloxazine analogs into c-kit PTK (PDB code: 1t46) revealed reasonable correlations between their AutoDock binding free energy and IC50.

New pyridine, pyrazoloyridine, and furopyridine derivatives substituted with naphthyl and thienyl moieties were designed and synthesized starting from 6-(naphthalen-2-yl)-2-oxo-4-(thiophen-2-yl)-1,2-dihydropyridine-3-carbonitrile (1). The chloro, methoxy, cholroacetoxy, imidazolyl, azide, and arylamino derivatives were prepared to obtain the pyridine-−C2 functionalized derivatives. The derived pyrazolpyridine-N-glycosides were synthesized via heterocyclization of the C2-thioxopyridine derivative followed by glycosylation using glucose and galactose. The furopyridine derivative 14 and the tricyclic pyrido[3′,2′:4,5]furo[3,2-d]pyrimidine 15 were prepared via heterocyclization of the ester derivative followed by a reaction with formamide. The newly synthesized compounds were evaluated for their ability to in vitro inhibit the CDK2 enzyme. In addition, the cytotoxicity of the compounds was tested against four different human cancer cell lines (HCT-116, MCF-7, HepG2, and A549). The CDK2/cyclin A2 enzyme inhibitory results revealed that pyridone 1, 2-chloro-6-(naphthalen-2-yl)-4-(thiophen-2-yl)nicotinonitrile (4), 6-(naphthalen-2-yl)-4-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridin-3-amine (8), S-(3-cyano-6-(naphthaen-2-yl)-4-(thiophen-2-yl)pyridin-2-yl) 2-chloroethanethioate (11), and ethyl 3-amino-6-(naphthalen-2-yl)-4-(thiophen-2-yl)furo[2,3-b]pyridine-2-carboxylate (14) are among the most active inhibitors with IC50 values of 0.57, 0.24, 0.65, 0.50, and 0.93 µM, respectively, compared to roscovitine (IC50 0.394 μM). Most compounds showed significant inhibition on different human cancer cell lines (HCT-116, MCF-7, HepG2, and A549) with IC50 ranges of 31.3–49.0, 19.3–55.5, 22.7–44.8, and 36.8–70.7 μM, respectively compared to doxorubicin (IC50 40.0, 64.8, 24.7 and 58.1 µM, respectively). Furthermore, a molecular docking study suggests that most of the target compounds have a similar binding mode as a reference compound in the active site of the CDK2 enzyme. The structural requirements controlling the CDK2 inhibitory activity were determined through the generation of a statistically significant 2D-QSAR model.

Recent drug discovery efforts are highly focused towards identification, design, and synthesis of small molecules as anticancer agents. With this aim, we recently designed and synthesized novel compounds with high efficacy and specificity for the treatment of breast tumors. Based on the obtained results, we constructed a Volsurf+ (VS+) model using a dataset of 59 compounds able to predict the in vitro antitumor activity against MCF-7 cancer cell line for new derivatives. In the present paper, in order to further verify the robustness of this model, we report the results of the projection of more than 150 known molecules and 9 newly synthesized compounds. We predict their activity versus MCF-7 cell line and experimentally verify the in silico results for some promising chosen molecules in two human breast cell lines, MCF-7 and MDA-MB-231.

Epidermal growth factor receptor (EGFR) and cyclooxygenase-2 (COX-2) are crucial targetable enzymes in cancer management. Therefore, herein, new 2-[(5-((1H-indol-3-yl)methyl)-1,3,4-oxadiazol-2-yl)thio]-N-(thiazol/benzothiazol-2-yl)acetamides (2a–i) were designed and synthesized as EGFR and COX-2 inhibitors. The cytotoxic effects of compounds 2a–i on HCT116 human colorectal carcinoma, A549 human lung adenocarcinoma, and A375 human melanoma cell lines were determined using MTT assay. 2-[(5-((1H-Indol-3-yl)methyl)-1,3,4-oxadiazol-2-yl)thio]-N-(6-ethoxybenzothiazol-2-yl)acetamide (2e) exhibited the most significant anticancer activity against HCT116, A549, and A375 cell lines with IC50 values of 6.43 ± 0.72 μM, 9.62 ± 1.14 μM, and 8.07 ± 1.36 μM, respectively, when compared with erlotinib (IC50 = 17.86 ± 3.22 μM, 19.41 ± 2.38 μM, and 23.81 ± 4.17 μM, respectively). Further mechanistic assays demonstrated that compound 2e enhanced apoptosis (28.35%) in HCT116 cells more significantly than erlotinib (7.42%) and caused notable EGFR inhibition with an IC50 value of 2.80 ± 0.52 μM when compared with erlotinib (IC50 = 0.04 ± 0.01 μM). However, compound 2e did not cause any significant COX-2 inhibition, indicating that this compound showed COX-independent anticancer activity. The molecular docking study of compound 2e emphasized that the benzothiazole ring of this compound occupied the allosteric pocket in the EGFR active site. In conclusion, compound 2e is a promising EGFR inhibitor that warrants further clinical investigations.

Luvunga scandens belongs to the family of Rutaceae which usually inhabit tropical and moist environment. This plant is known as ‘Mengkurat Jakun’ among locals and used traditionally to treat fever and fatigue via decoction. The aim of this study was to investigate the cytotoxic activity of the leaves and stems extracts of L. scandens extract. Extracts of the leaves and stems were obtained from sequential extraction procedures by various organic solvents. All extracts were subjected to cytotoxic study by 3-(4, 5-dimethylthaizol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. In in vitro cytotoxicity assay, all L. scandens extracts exhibited cytotoxicity against human breast adenocarcinoma (MCF-7) and human lung adenocarcinoma (A549) cell lines. The IC50 values of dichloromethane and methanol extracts from the leaves of L. scandens against MCF-7 cell line were 62.5 µg/mL and 88.0 µg/mL, respectively, whereas IC50 of methanol extract from stem was 81.0 µg/mL. All extracts were less active against A549 cell line where IC50 value were not be determined. The present findings revealed the potential of L. scandens as a cytotoxic agent against MCF-7 cell line. However, further studies should be planned to evaluate role of the plant in cytotoxic activity.
