Pyrazole Incorporated New Thiosemicarbazones: Design, Synthesis and Investigation of DPP-4 Inhibitory Effects

Dipeptidyl peptidase-4 (DPP-4) inhibition has been recognized as a promising approach to develop safe and potent antidiabetic agents for the management of type 2 diabetes. In this context, new thiosemicarbazones (2a-o) were prepared efficiently by the reaction of aromatic aldehydes with 4-[4-(1H-pyrazol-1-yl)phenyl]thiosemicarbazide (1), which was obtained via the reaction of 4-(1H-pyrazol-1-yl)phenyl isothiocyanate with hydrazine hydrate. Compounds 2a-o were evaluated for their DPP-4 inhibitory effects based on a convenient fluorescence-based assay. 4-[4-(1H-pyrazol-1-yl)phenyl]-1-(4-bromobenzylidene)thiosemicarbazide (2f) was identified as the most effective DPP-4 inhibitor in this series with an IC50 value of 1.266 +/- 0.264 nM when compared with sitagliptin (IC50 = 4.380 +/- 0.319 nM). MTT test was carried out to assess the cytotoxic effects of compounds 2a-o on NIH/3T3 mouse embryonic fibroblast (normal) cell line. According to cytotoxicity assay, compound 2f showed cytotoxicity towards NIH/3T3 cell line with an IC50 value higher than 500 mu M pointing out its favourable safety profile. Molecular docking studies indicated that compound 2f presented pi-pi interactions with Arg358 and Tyr666 via pyrazole scaffold and 4-bromophenyl substituent, respectively. Overall, in vitro and in silico studies put emphasis on that compound 2f attracts a great notice as a drug-like DPP-4 inhibitor for further antidiabetic research.

Enamines and Dimethylamino Imines as Building Blocks in Heterocyclic Synthesis: Reactions of DMF-DMA Reagent with Different Functional Groups

N,N-Dimethylformamide dimethyl acetal (DMF-DMA) reagent can react with different functional groups of organic compounds. Enamines and dimethylamino imines are obtained, when the DMF-DMA reagent is reacted with methylene, methyl and amino groups. These products are formed in the intermediate step in the synthesis of many hetero rings. These compounds are especially used as a starting material in the synthesis of heterostructures such as pyrimidine, pyridine, pyrazole, etc. Therefore, DMF-DMA has been particularly prominent as a reagent in targeted synthesis and designs of many heterocyclic compounds. Herein, the reactions of DMF-DMA reagent with different functional groups are categorized in four classes (methylene, methyl, amino, other groups) and the reactions of obtained enamine and dimethylamino imine compounds are investigated in detail such as nucleophilic addition, intramolecular cyclization or condensation reactions. The synthesis and continuation reactions of the enamine and dimethylamino imine compounds are also examined in terms of experimental conditions and reagents used.

Improving iodine adsorption performance of porous organic polymers by rational decoration with nitrogen heterocycle

Four kinds of porous aminal-linked organic polymers (PAOPs) were synthesized via one-step condensation between cheap melamine and respective aldehydes decorated with different nitrogen heterocycle, to evaluate the influence of nitrogen heterocycle on the adsorption performance of target polymer toward iodine. Though having the smallest surface area of 209.9 m(2)/g, PAOP-4 decorated with pyridine group exhibits an adsorption capacity of 108 wt% (iodine/adsorbent weight%), surpassing other three PAOPs with Brunauer-Emmett-Teller area varying from 305.8 to 533.0 m(2)/g. Based on Raman spectral analyses, the characteristic band of I(3)(-)and I(5)(-)was used to evaluate the electronic interaction between iodine and the nitrogen heterocycle, giving an order of pyridine > tetrazole > pyrazole > imidazole. This manifests the vital role of chemical interaction playing in the iodine adsorption by PAOP-4, which is much helpful for designing high-performance organic adsorbent toward iodine.

Synthesis of New Polyheterocyclic Ring Systems Derived from 3-Amino-5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridine

3-Amino-5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridine (2) was utilized as a precursor for the construction of new polyheterocyclic ring systems. It reacted with 4-substituted arylidene malononitriles and/or ethyl acetoacetate to furnish the corresponding pyrido[2′,3′:3,4]pyrazolo[1,5-a]pyrimidine derivatives 4a-c and 6, respectively. Diazotization of the precursor 2 followed by coupling with ethyl cyanoacetate was the route for the formation of pyrido[2′,3′:3,4]pyrazolo[5,1-c]triazine derivative 8. The synthesized N-(5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridin-3-yl)-2-cyanoacetamide (10) was utilized for the synthesis of 6-amino-4-aryl-1-(pyrazolo[3,4-b]-pyridin-3-yl)-1,2-dihydropyridines derivatives 12a-c via its treatment with three types of arylidene malononitrile. N-(5-Bromopyrazolo[3,4-b]pyridinyl)-2-(4-oxothiazolidin-2-ylidene)acetamide 13 and N-(5-bromopyrazolo[3,4-b]pyridinyl)-2-cyano-2-(4-oxo-3-phenylthiazolidin-2-ylidene)acetamide 15 were picked up through the reactions of 10 with 2-mercaptoacetic acid and/or Ph-N = C = S with BrCH2COOEt. The tricyclic ring system, 9-bromo-3-cyano-2-oxo-pyrido[2′,3′:3,4]pyrazolo[1,5-a]-pyrimidine derivative 18, was used as building block for the construction of new tetra- and penta-heterocyclic compounds 19, 20, and 21 through its reaction with some bis-nucleophilic reagents; hydrazine hydrate, malononitrile and 4-(4-anisylazo)-1H-pyrazole-3,5-diamine. The newly synthesized pyrazolo[3,4-b]pyridine-based heterocycles were characterized by the IR and H-1 NMR spectral techniques and their in vitro antibacterial properties were evaluated.

Synthesis, Biological Evaluation, and 3D-QSAR Studies of N-(Substituted pyridine-4-yl)-1-(substituted phenyl)-5-trifluoromethyl-1H-pyrazole-4-carboxamide Derivatives as Potential Succinate Dehydrogenase Inhibitors

A series of new fungicides that can inhibit the succinate dehydrogenase (SDH) was classified and named as SDH inhibitors by the Fungicide Resistance Action Committee in 2009. To develop more potential SDH inhibitors, we designed and synthesized a novel series of N-(substituted pyridine-4-yl)-1-(substituted phenyl)-5-trifluoromethyl-1H-pyrazole-4-carboxamide derivatives, 4a-4i, namely, 5a-5h, 6a-6h, and 7a-7j. The bioassay results demonstrated that some title compounds exhibited excellent antifungal activity against four tested phytopathogenic fungi (Gibberella zea, Fusarium oxysporum, Cytospora mandshurica, and Phytophthora infestans). The EC50 values were 1.8 mu g/mL for 7a against G. zeae, 1.5 and 3.6 mu g/mL for 7c against F. oxysporum and C mandshurica, respectively, and 6.8 mu g/mL for 7f against P. infestans. The SDH enzymatic activity testing revealed that the IC so values of 4c, 5f, 7f, and penthiopyrad were 12.5, 135.3, 6.9, and 223.9 mu g/mL, respectively. The molecular docking results of this series of title compounds with SDH model demonstrated that the compounds could completely locate inside of the pocket, the body fragment formed H bonds, and the phenyl ring showed a pi-pi interaction with Arg59, suggesting that these novel 5-trifluoromethyl-pyrazole-4-carboxamide derivatives might target SDH. These results could provide a benchmark for understanding the antifungal activity against the phytopathogenic fungus P. infestans and prompt us to discover more potent SDH inhibitors.

Synthesis and biological evaluation of novel pyrazoline derivatives containing indole skeleton as anti-cancer agents targeting topoisomerase II

In order to develop potent anticaner agents, a novel series of 3-(1H-indol-3-yl)-2,3,3a,4-tetrahydrothiochromeno[4,3-c]pyrazole derivatives were synthesized. Structures of all compounds were confirmed. MTT assay has been employed to study antiproliferative activity of these compounds with four human cancer cell lines (MGC-803, Hela, MCF-7 and Bel-7404) and a normal cell line L929. Most of these compounds showed potential anticancer activity and low cytotoxicity on normal cell in vitro. 7d and 7f showed the best anticancer activity, whose IC50 value is 15.43 mu M and 20.54 mu M towards MGC-803, respectively. Most of them exhibited topoisomerase II selective inhibitory. Cleavage reaction assay and DNA unwinding assay showed that 7f was a nonintercalative Topo II catalytic inhibitor, which was consistent with the docking results. Laser scanning confocal microscopy system tracks the location of representative compounds 7d and 7f which can be abundantly entering the nucleus. In particular, the most potent compounds 7d and 7f were shown to be able to induce G2/M cell cycle arrest and apoptosis in MGC-803 cells. (C) 2020 Elsevier Masson SAS. All rights reserved.

Anti-inflammatory and antinociceptive activity profile of a new lead compound-LQFM219

LQFM219 is a molecule designed from celecoxibe (COX-2 inhibitor) and darbufelone (inhibitor of COX-2 and 5-LOX) lead compounds through a molecular hybridisation strategy. Therefore, this work aimed to investigate the antinociceptive and anti-inflammatory activities of this new hybrid compound. The acute oral systemic toxicity of LQFM219 was evaluated via the neutral red uptake assay. Acetic acid-induced abdominal writhing and CFA-induced mechanical hyperalgesia were performed to evaluate the antinociceptive activity, and the anti-oede-matogenic activity was studied by CFA-induced paw oedema and croton oil-induced ear oedema. Moreover, the acute anti-inflammatory activity was determined by carrageenan-induced pleurisy. In addition, cell migration, myeloperoxidase enzyme activity, and TNF-alpha and IL-1 beta levels were determined in pleural exudate. Moreover, a redox assay was conducted using electroanalytical and DPPH methods. The results demonstrated that LQFM219 was classified as GHS category 4, and it showed better free radical scavenger activity compared to BHT. Besides, LQFM219 decreased the number of writhings induced by acetic acid and the response to the mechanical stimulus in the CFA-induced mechanical hyperalgesia test. Furthermore, LQFM219 reduced oedema formation, cell migration, and IL-1 beta and TNF-alpha levels in the pleural cavity and inhibited myeloperoxidase enzyme activity. Thus, our study provides that the new pyrazole derivative, LQFM219, demonstrated low toxicity, antinociceptive and anti-inflammatory potential in vitro and in vivo.
