Background and Objective: Due to the well-documented anti-proliferative activity of 2-thiohydantoin incorporated with pyrazole, oxadiazole, quinazoline, urea, β-naphthyl carbamate and Schiff bases, they are noteworthy in pharmaceutical chemistry. Methods: An efficient approach for the synthesis of a novel series of 2-thiohydantoin derivatives incorporated with pyrazole and oxadiazole has proceeded via the reaction of the acyl hydrazide with chalcones and/or triethyl orthoformate. Schiff bases were synthesized by the reaction of the acyl hydrazide with different aromatic aldehydes. Moreover, Curtius rearrangement was applied to the acyl azide to obtain the urea derivative, quinazoline derivative, and carbamate derivative. Results: The synthesized compounds structures were discussed and confirmed depending on their spectral data. The anticancer activity of these heterocyclic compounds was evaluated against the breast cancer cell line (MCF-7), where they showed variable activity. Compound 5d found to have a superior anticancer activity, where it has (IC50 = 2.07 ± 0.13 μg/mL) in comparison with the reference drug doxorubicin that has (IC50 = 2.79 ± 0.07 μg / mL). Then compound 5d subjected to further studies such as cell cycle analysis and apoptosis. Apoptosis was confirmed by the upregulation of Bax, downregulation of Bcl-2, and the increase of the caspase 3/7percentage. Conclusion: Insertion of pyrazole, oxadiazole and, quinazoline moieties with 2-thiohydantoin moiety led to the enhancement of its anti-proliferative activity. Hence they can be used as anticancer agents.

Abstract Novel nineteen compounds based on a 4-aminoquinoline scaffold were designed and synthesized as potential antiproliferative agents. The new compounds were N-substituted at the 4-position by aryl or heteroaryl (1-9), quinolin- 3-yl (10), 2-methylquinolin-3-yl (11), thiazol-2-yl (12), and dapsone moieties (13, 14 and 18). Bis-compounds 15, 16 and 19 were also synthesized to assess their biological activity. All the newly synthesized comounds were tested for in vitro antiproliferative activity against the MCF-7 breast cancer cell line. Seventeen of the novel compounds showed higher activity than the reference drug doxorubicin. The corresponding 7-(trifluoromethyl)-N-(3,4,5-trimethoxyphenyl)quinolin-4- amine 1, N-(7-(trifluoromethyl)quinolin-4-yl)quinolin- 3- amine (10), 2-methyl-N-(7-trifluorome-thyl)quinolin-4-yl) quinolin-3-amine (11) and N-(4-(4-aminophenylsulfonyl) phenyl)-7-chloroquinolin-4-amine (13) were almost twice to thrice as potent as doxorubicin. Biological screening of the tested compounds could offer an encouraging framework in this field that may lead to the discovery of potent anticancer agents.

Aims and Objective: A series of novel phthalazine derivatives was synthesized with versatile, readily accessible electrophilic and nucleophilic reagents. The newly synthesized compounds were confirmed by the results of spectroscopic measurements. Hence, their potential clinical application investigated in particular for cancer treatment. Materials and Methods: The newly synthesized compounds were characterized by spectroscopic measurements and were tested for their in vitro anticancer activity by MTT assay against human liver cancer cell line. Docking study of all the synthesized compounds was performed within the active site of the enzyme VEGFR-2 (Vascular Endothelial Growth Factor Receptor-2). Results: The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 µM. Docking study showed that the synthesized compounds were fit in the VEGFR-2 active site almost at the same position of sorafenib and vatalanib with comparable docking scores (-15.20 to -8.92 was kcal/mol). Conclusion: we have synthesized a novel series of phthalazine derivatives and evaluated their potential anticancer activity against HEPG2 cell line. The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 µM. The SAR and docking studies pointed out that rigidification of the structure resulted in better activity and better binding within the active site of VEGFR-2 as in compounds 3, 5, 6 and 12. These results introduced new phthalazine derivatives having promising activity which could lead to the development of more potent anticancer agents.

Background: Hydrazones, one of the important classes of organic molecules, are pharmaceutical agents comprising –CO-NH-N=CH- group in the structure therefore and exhibiting significant biological activity. Methods: 5-Chloro-N’-[(substituted)methylidene] pyrazine-2-carbohydrazide (3a-g) and their Pd(II) complexes (4a-h) were synthesized and investigated in vitro anticancer activity on A549, Caco2 cancer and normal 3T3 fibroblast cell lines, using the MTT assay. Results: Anticancer activity screening results revealed that some compounds showed remarkable cytotoxic effect. Among them, 5-chloro-N'-[(4-hydroxyphenyl)methylidene] pyrazine-2-carbohydrazide (3c) displayed higher cytotoxic activity against A549 cancer cell line than the reference drug cisplatin. Conclusion: Compound 3c showed high cytotoxic activity against A549 cancer cell line but it showed low cytotoxic effect against normal 3T3 fibroblast cell line. Antiproliferative and antimetastatic effects of 3c were determined by the real-time monitoring of cell proliferative system (RTCA DP). The cell proliferation, metastatic and invasive activities of A549 cells were decreased due to increased concentration of 3c.

Abstract Background Cancer is one of the most considerable concerns because of increasing the death rate all over the world. Recent studies have disclosed that plant extracts exhibit anticancer activity through various mechanisms. Xanthium strumarium has been used by Vietnamese in herbal medicines to support the medication of infirmities. This study is to consider the secondary metabolites, antioxidant and anticancer capacities of extract from the aerial parts (stems and leaves) of X. strumarium (AP-XS). Methods AP-XS was analyzed for the presence of phytochemicals via qualitative chemical tests and determined total polyphenol and flavonoid contents. DPPH (1,1-diphenyl-2-picrylhydrazyl) quenching assay and sulforhodamine B (SRB) assay were selected to investigate antioxidant capacity and anti-proliferative activity, respectively. Besides, acridine orange-ethidium bromide (AO-EB) dual staining was applied to evaluate the ability to induce apoptosis on HepG2 cancer cells. Results Results of present study indicated that AP-XS contains the main phytochemicals such as flavonoids, tannins, saponins, alkaloids, and triterpenes. Ethanol extract had highest content of polyphenol (84.86 mg gallic acid equivalent/g dry mass), and exhibited the great total antioxidant property (IC50 = 184.13 μg/mL) and anti-proliferative activity on HepG2 cancer cells (IC50 = 81.69 μg/mL). Furthermore, the characteristics of apoptosis including shrinkage of the cell and apoptotic bodies were found following 60 h of AP-XS extract treatment through AO-EB dual staining. Conclusion The data suggest that AP-XS extract had antioxidant potential and anti-proliferative effect. The anti-proliferative property was considered to have an association with a rising of apoptosis. These results were reliable for further research on X. strumarium as a source of phytochemicals with anticancer activity potential for cancer therapeutics.

A series of trans-6-phenylethenyl substituted pyridoxine derivatives, novel bioisosteric analogs of drugs based on trans-stilbene scaffold, were synthesized using the Wittig reaction of a bis-triphenylphosphonium pyridoxine derivative with various aromatic aldehydes. Two compounds demonstrated high activity against the estrogen-dependent MCF-7 (breast cancer) cell line with IC50 in the range of 1.9–7.9 µM and very good selectivity for other studied normal and tumor cells, including the estrogen receptor negative MDA-MB-231 breast cancer cells. The active compounds possessed an intense blue fluorescence, and this feature allowed us to effectively visualize them in cytoplasm and in nucleus. The obtained results make the described chemotype a promising starting point for the development of new anticancer agents for the therapy of estrogen-dependent malignancies.

Based on World Health Organization (WHO) report, it was estimated that one in five people before age 75 will suffer from cancer during their lifetime, and more than 13 million cancers death will happen in 2030. Chemotherapy is a basic approach for the treatment of cancer diseases. However, because of drug resistance and considerable side effects drug-induced toxicity, the discovery of new metal analogs with promising activity and high therapeutic index is an urgent need. The fundamental role of copper and the recognition of its complexes as important bioactive compounds in vitro and in vivo aroused an ever-increasing interest in these agents as potential drugs for therapeutic intervention in various diseases. Schiff bases are a critical class of compounds in medical chemistry that have demonstrated significant chemotherapeutic and antibacterial application. Schiff base Cu(II) complexes revealed great potential for antiproliferative, antibacterial, and gastroprotective activity. Coumarins are a wide class of natural and synthetic compounds that showed diverse pharmacological activities including anticancer activity. Among the wide variety of coumarins, 7-hydroxycoumarin derivatives have been shown to possess desirable antiproliferative activities. In particular, their antibacterial, antifungal and anticancer activities make the compounds attractive for further derivatization and screening as novel therapeutic agents. Taking these compounds as lead, we have designed and synthesized a series of new copper(II) complexes with coumarin-derived Schiff base ligands. Two series of Schiff bases were prepared by condensation of 8-formyl-7-hydroxy-4-methylcoumarin and 8-acetyl-7-hydroxy-4-methylcoumarin with p-substituted aniline derivatives. These compounds were used as ligands in the synthesis of copper(II) complexes. The obtained Schiff bases as well as copper complexes are mostly novel molecules. Only the products of condensation 8-formyl-7-hydroxy-4-methylcoumarin with p-toluidine and 8-acetyl-7-hydroxy-4-methylcoumarin with p-toluidine and its copper(II) complex were synthesized, but the anticancer activity of these compounds was not determined. The assay of their cytotoxic activity is in progress. Preliminary, we have identified two copper(II) coordination compounds of 7-hydroxy-8-[1-(4-methoxyphenyl imino)ethyl]-4-methyl-2H-chromen-2-one and 7-hydroxy-8-[1-(4-hydroxyphenyloimino)ethyl]-4-methyl-2H- chromen-2-one having dose-dependent antiproliferative activity on HeLa cancer cell line. Additionally, the Schiff bases – derivatives of substituted salicylaldehydes and 2-hydroxyacetophenones condensed with appropriate anilines were prepared. Such compounds have been reported in scientific papers, their copper complexes have not been assayed yet, and may serve as an useful tool in QSAR investigation.
