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.

A series of norcantharidin (NCTD) analogues have been synthesized by [3+2]1,3-dipolar cycloaddition reaction of norcantharidin derivatives of substituted aromatic amines with four nitrile oximes. All analogues have been screened for their antiproliferative activity in vitro against a panel of tumor cell lines: KB, SGC-7901, HL60, Bel-7402, HO-8910, and ECA109, producing IC50 values from 0.36 µmol/L to >100 µmol/L. Compound 9d showed potency for the treatment of hepatoma, with IC50 value to Bel-7402 cell line comparable to that of norcantharidin.Key words: norcantharidin analogues, isoxazoline, growth inhibition.

Background: Dimedone and thiazole moieties are privileged scaffolds (acting as primary pharmacophores) in many compounds that are useful to treat several diseases, mainly tropical infectious diseases. Thiazole derivatives are a very important class of compounds due to their wide range of pharmaceutical and therapeutic activities. On the other hand, dimedone is used to synthesize many therapeutically active compounds. Therefore, the combination of both moieties through a single molecule to produce heterocyclic compounds will produce excellent anticancer agents. Objective: The present work reports the synthesis of 47 new substances belonging to two classes of compounds: Dimedone and thiazoles, with the purpose of developing new drugs that present high specificity for tumor cells and low toxicity to the organism. To achieve this goal, our strategy was to synthesize a series of 4,5,6,7-tetrahydrobenzo[d]-thiazol-2-yl derivatives using the reaction of the 2-bromodimedone with cyanothioacetamide. Methods: The reaction of 2-bromodimedone with cyanothioacetamide gave the 4,5,6,7-tetrahydrobenzo[d]- thiazol-2-yl derivative 4. The reactivity of compound 4 towards some chemical reagents was observed to produce different heterocyclic derivatives. Results: A cytotoxic screening was performed to evaluate the performance of the new derivatives in six tumor cell lines. Thirteen compounds were shown to be promising toward the tumor cell lines which were further evaluated toward five tyrosine kinases. Conclusion: The results of antitumor screening showed that many of the tested compounds were of high inhibition towards the tested cell lines. Compounds 6c, 8c, 11b, 11d, 13b, 14b, 15c, 15g, 21b, 21c, 20d and 21d were the most potent compounds toward c-Met kinase and PC-3 cell line. The most promising compounds 6c, 8c, 11b, 11d, 13b, 14b, 15c, 15g, 20c, 20d, 21b, 21c and 21d were further investigated against tyrosine kinase (c-Kit, Flt-3, VEGFR-2, EGFR, and PDGFR). Compounds 6c, 11b, 11d, 14b, 15c, and 20d were selected to examine their Pim-1 kinase inhibition activity the results revealed that compounds 11b, 11d and 15c had high activities.

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.
