New lead discovery of insect growth regulators based on the scaffold hopping strategy

Insect growth regulators (IGRs), which can interrupt or inhibit pest life cycles, are low-toxicity pesticides widely used in integrated pest management (IPM). Ecdysone analogues and chitinase inhibitors are familiar IGRs that have attracted considerable attention because of their unique modes of action and low toxicity to non-target organisms. To find new and highly effective candidate IGRs with novel mechanisms, D-08 (N-(4-(tert-butyl) phenyl)-2-phenyl-2,4,5,6,7,8-hexahydrocyclohepta[c]pyrazole-5-carboxamide) was chosen as a lead compound, and a series of novel heptacyclic pyrazolamide derivatives were designed and synthesized using the scaffold hopping strategy. The bioassay showed that 111-27 (N-(2-methylphenethyl)-1-phenyl-1,4,5,6,7,8-hexahydrocyclohepta[c]pyrazole-5-carboxamide) had excellent activity against Plutella xylostella. Protein verification and molecular docking indicated that III-27 could act on both the ecdysone receptor (EcR) and Ostrinia furnacalis chitinase (Of ChtI) and is a promising new lead IGRs. The interaction mechanism of 111-27 with EcR and Of ChtI was then studied by molecular docking. These results provide important guidance for the study of new dual-target IGRs.

Fluorinated hydrazonoyl chlorides as precursors for synthesis of antimicrobial azoles

Hydrazonoyl halides have been known for their ability to react with different reagents to afford wide range of bioactive heterocyclic systems as thiazoles and imidazopyrazoles. This research work focused on the synthesis of two new fluorinated hydrazonoyl chlorides and used them in synthesis of novel series of thiazole derivatives and two imidazopyrazole systems. The mechanistic pathways and the structures of all synthesized derivatives were discussed and assured based on the available spectral data. The results of antimicrobial activity of the tested thiazoles and imidazopyrazoles showed that some derivatives have moderate to no activity against tested fungi and bacteria strains. Only one derivative namely 2-(2-(3-fluoro-4-methylphenyl)hydrazono)-7-(2-oxoindolin-3-ylidene)-2,7-dihydro-3H-imidazo[1,2-b]pyrazole-3,6(5H)-dione is the most active against Candida albicans (CA) with IZD = 20 mm, which was equipotent to ketoconazole. Furthermore, docking simulation was carried out to predict the binding pattern of the new compounds in the ATP binding site of the DNA gyrase B enzyme. The results of the docking simulation revealed that compounds 9a-e, 12, and 13a,b fit well in the ATP binding site of DNA gyrase B with docking score values ranging from -5.883 to -6.833 kcal/mol.

Cyclocondensation of 2-Hydroxyimino-1-(naphthalen-1-yl)butane-1,3-dione with Alkyl Hydrazines Leading to Substituted 4-Nitrosopyrazoles

Cyclocondensation of 2-(hydroxyimino)-1-(naphthalen-1-yl)butane-1,3-dione with alkyl hydrazines leading to new 1-alkyl-3(5)-methyl-5(3)-(naphthalene-1-yl)-4-nitrosopyrazoles is described. 8 previously unknown N-alkyl-4-nitrosopyrazoles with a 1-naphthalene substituent at the 3 or 5 position of the pyrazole ring were obtained as a result. It was found that yields of naphthyl-substituted pyrazoles with N-alkyl groups near the naphthalene substituent were significantly lower than for 3-(naphthalen-1-yl)-substituted pyrazoles. Particular yields of pairwise formed isomeric nitrosopyrazoles were associated with the different electrophilicity of the two carbonyl groups of the initial diketone. Using quantum chemical calculations by the DFT method B3LYP-D3/6-311G(d,p), the potential energies of the various conformers were estimated to draw a conclusion about the preferred attack of alkyl hydrazine on the carbonyl group, associated with the naphthalene ring.H-1 NMR and 2D(1)H-C-13 HSQC spectra of the compounds confirmed this direction of the reaction. The crystal structures of the synthesized compounds were established by X-ray powder diffraction technique. Crystal structure data were in agreement with quantum chemical calculations.

Synthesis, structural, molecular docking and spectroscopic studies of (E)-N’-(4-methoxybenzylidene)-5-methyl-1H-pyrazole-3-carbohydrazide

(E)-N’-4-methoxybenzylidene-5-methyl-1H-pyrazole-3-carbohydrazide (E-MBPC) has been synthesized and characterized by FT-IR, H-1 & C-13 NMR and ESI-MS spectroscopic methods. The (E)-configuration of hydrazonoic group was confirmed by single-crystal X-ray diffraction. Theoretical structures of E-MBPC in both gas phase and aqueous solution have been optimized by using hybrid B3LYP/6-311++G** calculations. Calculations in solution have shown that dipole moment increases from 7.97 D in the gas phase to 13.68 D in solution with solvation energy of -131.34 kJ/mol. Atomic charges have evidenced that the protonation of E-MBPC in solution could occur only in the N28 atom because those charges on this atom show negative values. Mapped MEP surfaces show that the nucleophilic sites is located on the O21 and N28 atoms including the N16 atom while the electrophilic sites are observed on the N24-H27 and N18-H19 bonds. NBO calculations support the high stability of E-MBPC in solution while frontier orbitals studies suggest low reactivity of E-MBPC in both media, as compared with the (E)-N’-(4-(dimethylamino)benzylidene)-5-methyl-1H-pyrazole-3-carbohydrazide derivative. The vibrational assignments of 93 vibration modes expected for E-MBPC were reported together with the corresponding force fields and force constants in both media. The predicted Raman and Ultraviolet-visible spectra were also reported for E-MBPC at the same level of theory. Good correlations were obtained between the predicted H-1- and C-13 NMR spectra and the corresponding experimental ones. In addition, molecular docking studies between the title ligand and 4AMJ protein were performed. Docking results revealed that the title compound can be designed as a potential anti-diabetic agent.

Copper-Catalyzed Aerobic Cyclization of ss,gamma-Unsaturated Hydrazones with Concomitant C=C Bond Cleavage

A Cu-catalyzed aerobic oxidative cyclization of ss,gamma-unsaturated hydrazones for the preparation of pyrazole derivatives has been developed. The hydrazonyl radical promoted the cyclization, along with a concomitant C=C bond cleavage of ss,gamma-unsaturated hydrazones. This process has been verified via several control experiments, including a radical-trapping study, an 18O-labeling method, and the identification of the possible byproducts. The advantages of this reaction include operational simplicity, a broad reaction scope, and a mild selective reaction process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 4233-33-4. Formula: C8H5N3O2.

Synthesis and antimycobacterial screening of new 4-(4-(1-benzyl-1H-1,2,3-triazol-4-yl)-1-phenyl-1H-pyrazol-3-yl)quinoline derivatives

A new series of 4-(4-(1-benzyl-1H-1,2,3-triazol-4-yl)-1-phenyl-1H-pyrazol-3-yl)quinoline (6a-t) have been synthesized by a click reaction of 4-(4-ethynyl-1-phenyl-1H-pyrazol-3-yl)quinoline (4a-d) with a substituted benzyl azide (5a-e). The starting alkyne derivatives4a-dare obtained from Bestmann-Ohira reaction of 1-phenyl-3-(quinolin-4-yl)-1H-pyrazole-4-carbaldehyde and dimethyl(1-diazo-2-oxopropyl)phosphonate. The newly synthesized compounds are screened againstM. tuberculosisH37Ra dormant and active,Escherichia coli,Pseudomonas fluorescence,Staphylococcus aureusandBacillus subtilisstrains at 30 mu g/mL concentration. Most of the screened compounds showed good to moderate antibacterial activity againstS. aureus,B. subtilis, andMycobacterium tuberculosisH37Ra strains. The synthesized derivatives of quinolinyl-pyrazole-4-carbaldehyde and quinolinyl-pyrazole-4-ethyne reportd good to moderate activity against both strains ofM. tuberculosisH37Ra. Ten derivatives of quinolinyl-pyrazole presented good activity againstB. subtilis. These results suggested that further optimization and development of quinolinyl-pyrazolyl-1,2,3-triazole moeity could serve as lead compounds for antimycobacterial activity.

Novel heterocyclic disazo dyes containing pyrazole and phenylpyrazole. part 1: Synthesis, characterization, solvent polarity and acid-base sensitive characteristics

A series of diazotised aniline and aniline derivative compounds were reacted with solution of malononitrile in pyridine at 0-5 degrees C were obtained 1a-1m compounds. Then 4-arylazo-3,5-diamino-1H-pyrazole (2a-2m) derivatives were synthesized by coupling arylazo malononitrile compounds with hydrazine. Finally, the synthesized pyrazole derivative 2a-2m compounds were again diazotised. By reacting these diazotised compounds with 3-amino-5-hydroxy-1-phenylpyrazole, the new thirteen heterocyclic disazo dyes (3a-3m) were joined the dye literature and the dye industry. The structures of these newly synthesized compounds were characterized using elemental analysis and spectroscopic methods such as Fourier transform infrared spectroscopy-Attenuated total reflectance (FT-IR-ATR), H-1-Nuclear magnetic resonance (H-1 NMR) spectroscopy and mass spectroscopy. Then solvatochromic properties and solvent effect in dimethyl sulfoxide, dimethyl formamide, acetonitrile, acetic acid, methanol and chloroform were investigated.

Roflumilast attenuates cognitive deficits in estrogen insufficient rats

Estrogen replacement therapy including specific estrogen receptor alpha (ER alpha) agonist, 4,4 ‘,4 ”-(4-propyl-[1H] pyrazole-1,3,5-triyl) trisphenol (PPT), improves cognitive function in the females with estrogen insufficiency condition. It is well suggested that the cyclic nucleotides are considered as one of the downstream mediators to ER alpha receptor activity and they can be hypothesized as a potential target in the management of estrogen insufficiency condition. Roflumilast, a phosphodiesterase-4 inhibitor, increases the level of cyclic adenosine monophosphate (cAMP) in most of the tissues including the brain, and is reported to have procognitive activity in the experimental animals. Hence, the present study evaluated the therapeutic effect of roflumilast with or without PPT in rats with experimentally-induced estrogen insufficiency. Estrogen insufficiency was induced in female rats through bilateral ovariectomy on day-1 (D-1) of the experimental schedule. Roflumilast (0.3 and 1.0 mg/kg; p.o.) and PPT (333 mu g/kg; i.p.) attenuated ovariectomy-induced cognitive deficits in the rodents during behavioral tests. Roflumilast and PPT increased the cholinergic function and cAMP level in the rat hippocampus and prefrontal cortex. Further, ovariectomy-induced decrease in the extent of phosphorylation of ER alpha in both the brain regions was attenuated with the monotherapy of either roflumilast or PPT. Interestingly, the combination of 1.0 mg/kg roflumilast and PPT exhibited better therapeutic effectiveness than their monotherapy. In addition, roflumilast facilitated PPT-induced increase in the level of expression of phosphorylated protein kinase-B (Akt) in both the rat brain regions. Hence, it can be assumed that the combination of roflumilast and PPT could be a therapeutic option in the management of estrogen insufficiency-induced disorders.

2-Aminobenzaldehyde, a common precursor to acridines and acridones endowed with bioactivities

By starting from a common substrate, 2-aminobenzaldehyde, both acridines and acridones were prepared. The former were generated in high yields by copper-catalyzed N-arylation followed by acid-mediated cyclization while the latter were obtained by double copper-catalyzed N-arylation followed by cyclization under the same reaction conditions. Moreover, acridine was subjected to deprotometalation by recourse to a lithium-zinc base and converted to the corresponding 4-iodo derivative, which was involved in copper-catalyzed couplings with pyrrolidinone and pyrazole. Finally, addition of pyrazole, indole and carbazole onto the 9 position of bare acridine was improved. While moderate biological activity was noticed in melanoma cells growth inhibition, the newly prepared compounds feature interesting photophysical properties which were evaluated in a preliminary study.

Synthesis of new pyrazolone and pyrazole-based adamantyl chalcones and antimicrobial activity

Chalcones and their derivatives are becoming increasingly popular due to their various pharmacological effects. Chalcone molecules may be extracted from natural resources, entirely synthesised, or biosynthesised by modifying the natural ones. In the present study, five pyrazole-based adamantyl heterocyclic compounds were synthesised by condensation of 1-adamantyl chalcone with substituted phenylhydrazine. The products were characterised by using H-1 NMR, C-13 NMR and FT-IR spectroscopy. The microbiological activity of these compounds was investigated against bacteria and fungi. The new compounds showed good to moderate activity against the microbial species used for screening. All developed molecules showed antibacterial activity against Gram-negative and Gram-positive. These molecules showed antifungal activities against Fusarium oxysporum fungus and in a dose-dependent manner, apart from RS-1 molecules which showed compromised antifungal activity and even at a high dose.
