Heterocyclic compounds have a large spectrum of biological activities including antitumor activity. The present study describes the cytotoxic effect of newly synthesized thiazole derivative (TD2) that can prove effective antitumor activity on both in vivo and in vitro studies. Objective: the essential objective of this research is to prove the cytotoxic effect of newly synthesized thiazole derivative (TD2) up on EAC bearing mice and many kinds of human cell lines. Materials and Methods: Antitumor activity of TD2 was examined on EAC in Swiss albino Mice at dose of 2.5 mg/kg. TD2 was injected for 10 following days after transplantation of tumor. After one day of last dose and 18 hours of fasting, 7 Mice were sacrificed and the remaining was kept to evaluate ILS %. Antitumor activity of TD2 was assessed by inspecting tumor volume, tumor weight, viable cell count and nonviable cell count, hematological, biochemical and antioxidant parameters of mice. Results: TD2 demonstrated an inhibitory effect on both cancer cell lines in vitro and Ehrlich ascites cells in vivo.TD2 increased in life span of Ehrlich–bearing mice compared to control. Cell cycle and flow cytometric analysis revealed that TD2 directed Ehrlich cells toward apoptosis by increasing of P53 expression. Conclusion: It was concluded that TD2 have a potent antitumor activity against Ehrlich ascites carcinoma in mice beside a cytotoxic effect on MCF-7, PC3, HepG2 and HCT-116.

Background: Thiazole nucleus–containing compounds have an antitumor efficiency against various types of cancer. Purpose: The present study was designed to determine the cytotoxic effect of newly synthesized thiazole derivative (TD1) on human cancer cell lines, in addition to evaluate its antitumor activity against Ehrlich ascites carcinoma (EAC) in mice. Materials and Methods: TD1 was synthesized and investigated for its cytotoxic effect on HCT116 (colon cancer), HepG2 (liver cancer), PC3 (prostate cancer) and MCF7 (breast cancer). The effect of TD1 on cell viability, tumor volume, and percent of increase in life span (% ILS) in Ehrlich–bearing mice was studied. Hematological parameters, liver and kidney function tests were evaluated. The activity of superoxide dismutase (SOD) and catalase (CAT), as well as malondialdehyde (MDA) and reduced glutathione levels were determined in liver and kidney tissues. The expression of P53 in EAC was analyzed by flow cytometry. Results: TD1 demonstrated an inhibitory effect on both cancer cell lines in vitro and Ehrlich ascites cells in vivo. TD1 increased in life span of Ehrlich–bearing mice compared to control. Cell cycle and flow cytometric analysis revealed that TD1 directed Ehrlich cells toward apoptosis by increasing of P53 expression. Conclusion: It was concluded that TD1 have a potent antitumor activity against Ehrlich ascites carcinoma in mice beside a cytotoxic effect on MCF-7, PC3, HepG2 and HCT-116.

A series of new phenanthrene-based tylophorine derivatives (PBTs) were synthesized in good yield and their structures were characterized by 1H-NMR spectroscopy and ESI MS. In vitro antitumor activity of these compounds against five human carcinoma cell lines, including HCT116 (colorectal), BGC-823 (gastric), HepG-2 (hepatic), Hela (cervical) and H460 (lung) cells, was evaluated by MTT assay. Among these PBTs, compound 6b showed the highest antitumor activities against HCT116 and HepG-2 cell lines with IC50 values of 6.1 and 6.4 μM, respectively, which were comparable to that of adriamycin hydrochloride. The structure-activity relationship of these compounds was also discussed based on the results of their antitumor activity.

Background: Spirocyclic indoline compounds widely exist in numerous natural products with good biological activities and some drug molecules in many aspects. In recent years, it has attracted extensive attention as potent anti-tumor agents in the fields of pharmacology and chemistry. Objective: In this study, we focused on designing and synthesizing a set of novel 1'-H-spiro[indole-3,4'-piperidine] derivatives, which were evaluated by preliminary bioactivity experiment in vitro and molecular docking. Method: The key intermediate 1'-methylspiro[indoline-3,4'-piperidine] (B4) reacted with benzenesulfonyl chloride with different substituents under alkaline condition to obtain its sulfonyl derivatives (B5-B10). We evaluated their antiproliferative activities against A549, BEL-7402 and HeLa cells by MTT assay. We performed the CDOCKER module in Discovery Studio 2.5.5 software for molecular modeling of compound B5, and investigated the binding of compound B5 with the target proteins from PDB database. Results: The results indicated that compounds B4-B10 exhibited good antiproliferative activities against the above three types of cells, in which compound B5 with chloride atom as electron-withdrawing substituent on a phenyl ring showed the highest potency against BEL-7402 cells (IC50=30.03±0.43 μg/mL). By binging of the prominent bioactive compound B5 to CDK, c-Met, EGFR protein crystals, The binding energy of B5 with these three types receptors are -44.3583 kcal/mol, - 38.3292 kcal/mol, -33.3653 kcal/mol respectively. Conclusion: Six 1'-methylspiro[indoline-3,4'-piperidine] derivatives were synthesized and evaluated against BEL-7402, A- 549, HeLa cell lines. Compound B5 showed significant inhibition on BEL-7402 cell lines. Molecular docking revealed that B5 showed good affinity by the good fitting between B5 and these three targets with amino acid residues in active sites which encourage us to conduct further evaluation such as the kinase experiment.

Background: Chemotherapy is one of the mainstays of cancer treatment, despite the serious side effects of the clinically available anticancer drugs. In recent years increasing attention has been directed towards novel agents with improved efficacy and selectivity. Compounds with chalcone backbone have been reported to possess various biological activities such as anticancer, antimicrobial, anti-inflammatory, analgesic, antioxidant, etc. It was reported that aminomethylation of hydroxy chalcones to the corresponding Mannich bases increased their cytotoxicity. In this context, our interest has been focused on the design and synthesis of the so-called multi-target molecules, containing two or more pharmacophore fragments. Methods: A series of Mannich bases were synthesized by the reaction between 6-[3-(3,4,5- trimethoxyphenyl)-2-propenoyl]-2(3Н)-benzoxazolone, formaldehyde, and a secondary amine. The structures of the compounds were confirmed by elemental analysis, IR and NMR spectra. The new Mannich bases were evaluated for their in vitro cytotoxicity against a panel of human tumor cell lines, including BV-173, SKW-3, K-562, HL-60, HD-MY-Z and MDA-MB-231. The effects of selected compounds on the cellular levels of glutathione (GSH) were determined. Results: The new compounds 4a-e exhibited concentration-dependent cytotoxic effects at micromolar concentrations in MTT-dye reduction assay against a panel of human tumor cell lines, similar to those of starting chalcone 3. The tested agents led to concentration - dependent depletion of cellular GSH levels, whereby the effects of the chalcone prototype 3 and its Mannich base-derivatives were comparable. Conclusion: The highest chemosensitivity to the tested compounds was observed in BV- 173followed by SKW-3 and HL-60 cell lines.

Background: Natural plant metabolites and their semisynthetic derivatives have been used for years in cancer therapy. Xanthones are oxygenated heterocyclic compounds produced as secondary metabolites by higher plants, fungi or lichens. Xanthone core may serve as a template in the synthesis of many derivatives that have broad biological activities. Objective: This study synthesized a series of 17 new xanthones, and their anticancer potential was also evaluated. Methods: The anticancer potential was evaluated in vitro using a highly invasive T24 cancer cell line. Direct cytotoxic effects of the xanthones were established by IC50 estimation based on XTT assay. Results: 5 compounds of the total 17 showed significant cytotoxicity toward the studied cancer cultures and were submitted to further detailed analysis, including studies examining their influence on gelatinase A and B expression, as well as on the cancer cells migration and adhesion to an extracellular matrix. These analyses were carried out on five human tumor cell lines: A2780 (ovarian cancer), A549 (lung cancer), HeLa (cervical cancer), Hep G2 (liver cancer), and T24 (urinary bladder cancer). All the compounds, especially 4, showed promising anticancer activity: they exhibited significant cytotoxicity towards all the evaluated cell lines, including MCF-7 breast cancer, and hindered migration-motility activity of cancer cells demonstrating more potent activity than α-mangostin which served as a reference xanthone. Conclusion: These results suggest that our xanthone derivatives may be further analyzed in order to include them in cancer treatment protocols.

Scaffolds hybridization is a well-known drug design strategy for antitumor agents. Herein, series of novel indolyl-pyrimidine hybrids were synthesized and evaluated in vitro and in vivo for their antitumor activity. The in vitro antiproliferative activity of all compounds was obtained against MCF-7, HepG2, and HCT-116 cancer cell lines, as well as against WI38 normal cells using the resazurin assay. Compounds 1–4 showed broad spectrum cytotoxic activity against all these cancer cell lines compared to normal cells. Compound 4g showed potent antiproliferative activity against these cell lines (IC50 = 5.1, 5.02, and 6.6 μM, respectively) comparable to the standard treatment (5-FU and erlotinib). In addition, the most promising group of compounds was further evaluated for their in vivo antitumor efficacy against EAC tumor bearing mice. Notably, compound 4g showed the most potent in vivo antitumor activity. The most active compounds were evaluated for their EGFR inhibitory (range 53–79 %) activity. Compound 4g was found to be the most active compound against EGFR (IC50 = 0.25 µM) showing equipotency as the reference treatment (erlotinib). Molecular modeling study was performed on compound 4g revealed a proper binding of this compound inside the EGFR active site comparable to erlotinib. The data suggest that compound 4g could be used as a potential anticancer agent.
