Introduction: This study aimed to evaluate the antioxidant property of silymarin (SM) extracted from the seed of Silybum marianum and its anticancer activity on KB and A549 cell lines following 24, 48, and 72 h of treatment. Methods: Ten grams of powdered S. marianum seeds were defatted using n-hexane for 6 hours and then extracted by methanol. The silymarin extracted of extraction components The extracted components of silymarin were measured by spectrophotometric assay and HPLC analysis. 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, phenol content, total flavonoid content, and total antioxidant capacity were measured to detect the antioxidant properties of SM. The anticancer activity of the SM on cell lines evaluated by MTT. Results: In HPLC analysis, more than 50% of the peaks were related to silibin A and B. SM was reducedDPPH (the stable free radical) with a 50% inhibitory concentration (IC50) of 6.56 μg/ ml in comparison with butylated hydroxyl toluene (BHT), which indicated an IC50 of ~3.9 μg/ ml.The cytotoxicity effect of SM on the cell lines was studied by MTT assay. The cytotoxicity effect of the extracted silymarin on KB and A549 cell lines was observed up to 80 and 70% at 156 and 78 µg/ml, respectively. The IC50 value of the extracted SM on KB and A549 cell lines after 24 hours of treatment was seen at 555 and 511 µg/ml, respectively. Conclusion: Due to the good antioxidant and anticancer properties of the isolated silymarin, its use as an anticancer drug is suggested.

Background: Cancer is a disease illustrated by a shift in the controlled mechanisms that control both cell proliferation and differentiation. It is regarded as a prime health problem worldwide, leading cause of human death-rate exceeded only by cardiovascular diseases. Many reported work was concerned with the discovery of new antitumor compounds this encourage us to synthesis new anticancer agents. Objective: In this work, we are aiming to synthesize target molecules from 1,3-dicarbonyl compounds through many heterocyclization reactions. Method: The reaction of either 4-methylaniline (1a) or 1-naphthylamine (1b) with diethyl malonate (2) gave the anilide derivatives 3a and 3b, respectively. The latter products underwent a series of heterocyclization reactions to give the pyridine, pyran andthiazole derivatives which confirmed with the required spectral data. Results: Thein-vitro antitumor evaluations of the newly synthesized products against four cancer cell lines MCF-7, NCI-H460, SF-268 and WI 38 as normal cell line were screened and the data revealed that compounds 11a, 18b, 18c and 20d showed high antitumor activity and 20dindividualize with potential antitumor activity towards cell lines with lowest cytotoxicity effect. Both EGFR and PIM-1 enzyme inhibition were investigated for the compound 20d and his inhibition effect was promising for each enzyme showing IC50=45.67 ng and 553.3 ng for EGFR and PIM-1, respectively. Conclusion: Molecular docking results of compound 20d showed a strong binding interactions on both enzymes, where, good binding modes obtained on case of EGFR, which closely similar to the binding mode of standard Erlotinib. While, 20d showed complete superimposition binding interactions with VRV-cocrystallized ligand of PIM-1 that may expounds the in-vitro antitumor activity.

Background: Cancer disease is making a serious concern globally. Global cancer occurrence is steadily increasing every year. There is always a persistent need to develop new anticancer drugs with reduced side effects or act synergistically with the existing chemotherapeutics. Objective: Benzoxazoles are fused bicyclic nitrogen and oxygen-containing heterocyclic compounds and are considered biologically privileged scaffolds. We designed a synthetic route to link the benzoxazoles with oxadiazoles resulting in a better pharmacophore for anticancer activity. Methods: A series of novel amide derivatives of benzoxazole linked 1,3,4-oxadiazoles (10a-j) were synthesized and characterized by 1H NMR, 13C NMR, and mass spectroscopic techniques. The biological properties of the compounds were screened in vitro against four different tumor cell lines. Results: The results suggest that the compound 10b having 3,4,5-trimethoxy substitution on the phenyl ring exhibited potent anticancer activity in three cell lines (A549 = 0.13 ± 0.014 µM, MCF-7 = 0.10 ± 0.013 µM and HT-29 = 0.22 ± 0.017 µM). Notably, among the synthesized derivatives, compounds 10b, 10c, 10f, 10g, and 10i exhibited potent anticancer activity than the control IC50 in the range of 0.11 ± 0.02 to 0.93 ± 0.034 µM. Molecular docking simulation results showed compounds were stabilized by hydrogen bond and π-π interactions with the protein. Conclusion: The molecules showed comparable binding affinities with standard Combretastatin-A4. The present research work is preliminary and needs further studies to take the synthesized compounds to the next level in the cancer research field.

In this work, some 2-phenyl quinoline-4-carboxamide derivatives (5a-j) were synthesized via base catalyzed Pfitzinger reaction of isatin and acetophenone followed by C-N coupling reaction using POCl3 and assessed them for their in vitro antimicrobial and anticancer activity. The structure of newly synthesized compound were established by FT-IR, 1H & 13C NMR and Mass spectrometric analysis. The synthesized carboxamides were subjected to preliminary in vitro antibacterial activity as well as for antifungal activity. Results of antibacterial activity were compared with standard antibacterial (ciprofloxocin) and antifungal (fluconozole). Among the tested compounds, 5d, 5f and 5h exhibited promising activity with zone of inhibition ranging from 10 to 25 mm. Further, the anticancer activity determined using MTT assay against two cancer cell lines. Compounds 5b, 5d, 5f and 5h showed good anticancer activity among all the other derivatives. In order to correlate the in vitro results, in silico ADME and Molecular docking studies were carried out for (5a-j). ADME properties results showed that all the compounds obey rule of Five rule except 5a, 5e and 5g compound. Molecular docking studies of the synthesized compounds showed good binding affinity through hydrogen bond interactions with key residues on active sites as well as neighboring residues within the active site of chosen target proteins viz. antibacterial, antifungal and anticancer. Comparison of both results of in silico as well as in vitro investigation suggests that the synthesized compounds may act as potential antimicrobial as well as anticancer agents.

Nowadays, hybrid drugs have gained a significant role in the treatment of different health problems. Most of the hybrid molecules with different heterocyclic moieties were proved to be potent anti-tumor agents in cancer chemotherapy. Hence, the present study is aimed at the evaluation of in vitro anticancer activity of novel hybrid molecules (pyrazolyl benzoxazole conjugates) and to investigate their anticancer activity by molecular docking studies. Designed, synthesized and characterized the novel pyrazolyl benzoxazole conjugates. Anticancer activity of these compounds was determined by SRB assay. Then molecular docking studies were carried out against proto-oncogene tyrosine-protein kinase (ATP-Src, PDB: 2BDF), a putative target for cancer. All the synthesized compound derivatives were evaluated against MCF-7, KB, Hop62 and A549 cancer cell lines. Compounds 9b and 9c exhibited excellent anticancer activities with GI50 values of <0.1 µM against MCF-7 and A549 cell lines. Compound 9e exhibited good antitumor activity on MCF-7 and A-549 with GI50 values of 0.12 µM and 0.19 µM respectively. Compound 9g showed better anticancer activity on A-549 cancer cell line with GI50 of 0.34 µM. The two-hybrid molecules 9b and 9c are found to be comparably potent with the standard drug doxorubicin and may act as drug lead compounds in medicinal chemistry aspect. The present docking investigation proved that having benzoxazole of compound 9c at the position of benzofuran of reference compound (N-acetyl pyrazoline derivative) might be valid for contributing to anti-cancer activity.
