Aim and Objective: Isoxazolines are an important class of nitrogen and oxygen-containing heterocycles, which have gained much importance as the potential biological agents. In order to study structureactivity relationships of isoxazolines, this work has been conducted. Materials and Methods: A series of new piperazine substituted 3, 5-diarylisoxazoline derivatives (6-31) were designed and synthesized, and in vitro anti-inflammatory activity in lipopolysaccharide (LPS)-stimulated RAW-264.7 macrophages and anticancer effect against a panel of human tumor cell lines (Hela, A549 and SGC7901) by MTT assay were evaluated. Results: The substituents of the NH group of piperazine ring had an obvious influence on biological activities. Especially, compounds 5, 7, 8, 10, 11, 13 and 27-showed good inhibitory effect on the generation of NO compared to dexamethasone. Furthermore, derivatives 5, 6, 7, 8, 9, 13 and 26 were found to be potential selectively anticancer activity on human tumor cell lines, which displayed better cytotoxic activity to positive control 5- FU. Conclusion: Piperazine substituted 3, 5-diarylisoxazoline derivatives could be considered as new antiinflammatory and anticancer agents.

Abstract Guanylhydrazones have shown promising antitumor activity in preclinical tumor models in several studies. In this study, we aimed at evaluating the cytotoxic effect of a series of synthetic guanylhydrazones. Different human tumor cell lines, by including HCT-8 (colon carcinoma), MDA-MB-435 (melanoma) and SF-295 (glioblastoma) were continuous exposed to guanylhydrazone derivatives for 72 hours and growth inhibition of tumor cell lines and macrophages J774 was measured using tetrazolium salt (MTT) assay. Compounds 7, 11, 16 and 17 showed strong cytotoxic activity with IC50 values lower than 10 μmol L−1 against four tumor cell lines. Among them, 7 was less toxic to non-tumor cells. Finally, obtained data suggest that guanylhydrazones may be regarded as potential lead compounds for the design of novel anticancer agents.

Anticancer activity of a series of 3-(hetaryl/aryl)amino substituted isoquinolin-1(2H)-ones has been studied within the international scientific program “NCI-60 Human Tumor Cell Lines Screen”. Screening was performed in vitro on 60 cell lines of lungs, kidneys, CNS, ovaries, prostate, and breast cancer, epithelial cancer, leukemia, and melanoma. The most effective compounds were those with thiazolyl or pyrazolyl substituent at 3-amino group and had no substituents at C(4) of the isoquinoline cycle. We identified a new lead compound, 3-(1,3-thiazol-2-ylamino)isoquinolin-1(2H)-one 12, which effectively prevents tumor cell growth (average lg GI50 = -5.18, lg TGI = -4.1, lg LC50 > -4.0) with good selectivity.

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.

Signal transducer and activator of transcription 3 (STAT3) is a transcriptional regulator of a number of biological processes including cell differentiation, proliferation, survival, and angiogenesis, while cyclin-dependent kinases (CDKs) are a critical regulator of cell cycle progression. These proteins appear to play central roles in angiogenesis and cell survival and are widely implicated in tumor progression. In this study, we used the well-characterized US National Cancer Institute 60 (NCI60) human tumor cell lines to screen the in vitro anti-cancer activities of our novel small molecule derivatives (NSC765690 and NSC765599) of salicylanilide. Furthermore, we used the DTP-COMPARE algorithm and in silico drug target prediction to identify the potential molecular targets, and finally, we used molecular docking to assess the interaction between the compounds and prominent potential targets. We found that NSC765690 and NSC765599 exhibited an anti-proliferative effect against the 60 panels of NCI human cancer cell lines, and dose-dependent cytotoxic preference for NSCLC, melanoma, renal, and breast cancer cell lines. Protein–ligand interactions studies revealed that NSC765690 and NSC765599 were favored ligands for STAT3/CDK2/4/6. Moreover, cyclization of the salicylanilide core scaffold of NSC765690 mediated its higher anti-cancer activities and had greater potential to interact with STAT3/CDK2/4/6 than did NSC765599 with an open-ring structure. NSC765690 and NSC765599 met the required safety and criteria of a good drug candidate, and are thus worthy of further in-vitro and in-vivo investigations in tumor-bearing mice to assess their full therapeutic efficacy.

With the ligands 4-phenyl-1-(furan-2-carbaldehyde)thiosemicarbazone, HTSC1, (1), 4-phenyl-1- (5´-phenyl-furan-2-carbaldehyde)thiosemicarbazone, HTSC2 (2), o-methoxy-benzaldehydethiosemicarbazone, HTSC3 (3), and o-cyano-benzaldehydethiosemicarbazone, HTSC4 (4), the corresponding palladium(II) complexes, Pd(TSC1)2 (5), Pd(TSC2)2 (6), Pd(TSC3)2 (7), and Pd(TSC4)2 (8) were synthesized and characterized by elemental analysis and spectroscopic techniques. The crystal structure of Pd(TSC3)2 (7) was determined by single-crystal X-ray diffraction. Complex 7 shows a squareplanar geometry, where two deprotonated ligands are coordinated to the PdII center through the nitrogen and sulfur atoms in a trans arrangement. In vitro antitumor studies against different human tumor cell lines have revealed that the palladium(II) complexes 5- 8 are more cytotoxic (IC50 values in the range of 0.21 - 3.79 μM) than their corresponding ligands (1 - 4) (> 60 μM). These results indicate that the antiproliferative activity is enhanced when thiosemicarbazone ligands are coordinated to the metal. Among the studied palladium(II) complexes, 8 exhibits high antitumor activity on K562 chronic myelogenous leukemia cells with a low value of the inhibitory concentration (IC50 = 0.21 μM).
