Abstract
A novel catalyst has been afforded by attaching of a Cu(proline)2 complex to magnetic nanoparticles through cheap, simple, and readily available chemicals. This catalyst was characterized by Fourier transform infrared, energy-dispersive X-ray, X-ray diffraction, vibrating-sample magnetometry, transmission electron microscopy, scanning electron microscopy, and inductively coupled plasma analyses. The catalytic activity of the Fe3O4@NH2@TCT@HProCu nanocatalyst was investigated in a green and effective synthesis of pyran derivatives in high yields by applying three-component reactions of malononitrile, dimedone, and aldehydes in ethanol. Conversion was high under optimal conditions. The obtained nanocatalyst could be easily separated from the mixture of the reaction and was recyclable nine times via a simple magnet without considerable reduction of its catalytic efficiency. Operational simplicity, high product yields, environmental friendliness, ecofriendliness, economical processing, and easy workup are the features of this methodology.

Abstract
Thiazole-substituted pyrazole is an important structural feature of many bioactive compounds, including antiviral, antitubercular, analgesic and anticancer agents. Herein we describe an efficient and facile approach for the synthesis of two series of 36 novel N-bridged pyrazole-1-phenylthiazoles. The antiproliferative activity of a set of representative compounds was evaluated in vitro against different human cancer cell lines. Among the identified compounds, compound 18 showed potent anticancer activity against the examined cancer cell lines. The in silico molecular docking study revealed that compound 18 possesses high binding affinity toward both SK1 and CDK2. Overall, these results indicate that compound 18 is a promising lead anticancer compound which may be exploited for development of antiproliferative drugs.

Abstract
Pyrazolothiazole-substituted pyridine conjugates are an important class of heterocyclic compounds with an extensive variety of potential applications in the medicinal and pharmacological arenas. Therefore, herein, we describe an efficient and facile approach for the synthesis of novel pyrazolo-thiazolo-pyridine conjugate 4, via multicomponent condensation. The latter compound was utilized as a base for the synthesis of two series of 15 novel pyrazolothiazole-based pyridine conjugates (5-16). The newly synthesized compounds were fully characterized using several spectroscopic methods (IR, NMR and MS) and elemental analyses. The anti-proliferative impact of the new synthesized compounds 5-13 and 16 was in vitro appraised towards three human cancer cell lines: human cervix (HeLa), human lung (NCI-H460) and human prostate (PC-3). Our outcomes regarding the anti-proliferative activities disclosed that all the tested compounds exhibited cytotoxic potential towards all the tested cell lines with IC50 = 17.50-61.05 µM, especially the naphthyridine derivative 7, which exhibited the most cytotoxic potential towards the tested cell lines (IC50 = 14.62-17.50 µM) compared with the etoposide (IC50 = 13.34-17.15 µM). Moreover, an in silico docking simulation study was performed on the newly prepared compounds within topoisomerase II (3QX3), to suggest the binding mode of these compounds as anticancer candidates. The in silico docking results indicate that compound 7 was a promising lead anticancer compound which possesses high binding affinity toward topoisomerase II (3QX3) protein.

Abstract
Aims & Objective:
In this work, pyran derivatives were synthesized via a multicomponent
reaction of ninhydrin, α-haloketones, dialkyl acetylenedicarboxylate, and triphenylphosphine in the
presence of iron oxide magnetic nanoparticles (Fe3O4-MNPs) as efficient nanocatalyst in ethanol at
room temperature.
Materials & Methods:
The biosynthesis of Fe3O4-MNPs was performed by Clover Leaf water
extract. In addition, antioxidant activity was examined for the prepared compounds employing
DPPH radical scavenging and ferric reduction activity potential (FRAP) experiment and comparing
results with synthetic antioxidants (TBHQ and BHT).
Results:
Compound 5b showed excellent radical trapping activity and good reducing activity
relative to standards (BHT and TBHQ).
Conclusion:
Some advantages of this procedure are: the workup of reaction is easy and the
products can be separated easily by filtration. Fe3O4-MNPs display a good improvement in the
yield of the product and showed significant reusable activity.

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.
