Abstract
Background:
A wide range of thiazole, pyrazole and pyran derivatives gained special
attention due to pharmacological activities especially therapeutic activities. Many pharmacological
drugs containing the thiazole and pyrazole nuclei are known in the market.
Methods:
The 2-arylidencyclohexan-1,3-dione 3a-c were the key starting compounds for many
heterocyclic reactions to produce substituted heterocyclic derivatives.
Results:
Antiproliferative activities of the produced compounds against six cancer cell lines A549,
HT-29, MKN-45, U87MG, SMMC-7721 and H460 were measured in which the compounds showed
high inhibition. The most promising compounds were tested against tyrosine kinases (c-Kit, Flt-3,
VEGFR-2, EGFR, and PDGFR). Structure-Activity Relationship (SAR) was rationalized by
assessing the varying structural features of the molecules. In addition, the most active compounds
were selected for Pim-1 inhibition.
Conclusion:
Thirty compounds were synthesized. Ten of them (3a, 3c, 5a, 5c, 7a, 10f, 11a, 13c, 16a
and 16c) were the most active compounds for selected cancer cell lines. Compounds 3c, 5c, 7a, 10f,
13c and 16c showed high inhibition toward the tyrosine kinases while compounds 3c, 5c and 10f
were the most potent to inhibit Pim-1.

Anticancer Agents Med Chem 2020; 19:1438-1453. [PMID: 31038076 DOI: 10.2174/1871520619666190416102144] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Revised: 02/01/2019] [Accepted: 03/28/2019] [Indexed: 11/22/2022]
Abstract
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
Herein, a novel DABCO-based dicationic ionic liquid (bis-DIL) was easily prepared from the sonication of DABCO with 1,3-dichloro-2-propanol and then characterized by several techniques. Thereafter, under the ultimate green conditions, the performance of the bis-DIL was examined for the sono-synthesis of a new library of bis-2-amino-5-arylidenethiazol-4-ones via one-pot pseudo-five-component Knoevenagel condensation reaction of appropriate dialdehydes, rhodanine and amines. This protocol is tolerant towards several mono- and dialdehydes, excellently high yielding and affording access to the desired products in a single step within a short reaction time. Compared with the conventional methodologies, the proposed method displayed several remarkable merits such as milder reaction conditions without any side product, green solvent media, recording well in a variety of green metrics and applicability in gram-scale production. The recyclability of the bis-DIL was also investigated with an average recovered yield of 97% for six sequential cycles without any significant loss of the activity.

Abstract
Knoevenagel condensation was employed to generate a set of molecules potentially capable of inhibiting the RNA polymerase-σ70/σA interaction in bacteria. Synthesis was achieved via reactions between a variety of indole-7-carbaldehydes and rhodanine, N-allylrhodanine, barbituric acid or thiobarbituric acid. A library of structurally diverse compounds was examined by enzyme-linked immunosorbent assay (ELISA) to assess the inhibition of the targeted protein-protein interaction. Inhibition of bacterial growth was also evaluated using Bacillus subtilis and Escherichia coli cultures. The structure-activity relationship studies demonstrated the significance of particular structural features of the synthesized molecules for RNA polymerase-σ70/σA interaction inhibition and antibacterial activity. Docking was investigated as an in silico method for the further development of the compounds.
