Discovery and SAR study of piperidine-based derivatives as novel influenza virus inhibitors

A series of piperidine-based derivatives were identified as novel and potent inhibitors of the influenza virus through structural modification of a compound that was selected from a high-throughput screen. Various analogues were synthesized and confirmed as inhibitors. The structure-activity relationship (SAR) studies suggested that the ether linkage between the quinoline and piperidine is critical for the inhibitory activity. The optimized compound tert-butyl 4-(quinolin-4-yloxy)piperidine-1-carboxylate 11e had an excellent inhibitory activity against influenza virus infection from a variety of influenza virus strains, with EC50values as low as 0.05 muM. The selectivity index value (SI = MLD50/EC50) of 11e is over 160 000 based on cytotoxicity, measured by MTT assays of three cell lines. We carried out a time-of-addition experiment to delineate the mechanism of inhibition. The result indicates that 11e interferes with the early to middle stage of influenza virus replication.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Safety of 3-Hydroxytetrahydrofuran, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 453-20-3

Characterization of Secondary Metabolites from Various Solvent Extracts of Saffron Floral Waste

Isolation of secondary metabolites from saffron flower waste (stamens), and their identification using chromatographic techniques was carried out. Extraction was carried out with solvents (methanol, ethanol, ethyl acetate, diethylether and hexane) with different polarity. Gas chromatography?mass spectroscopy (GC?MS) technique was used for identification and structure elucidation of secondary metabolites obtained from saffron flower stamens. Chromatogram of ethanol showed higher peak area as compared to other solvents. Ethanol extract showed maximum number of peaks while chromatogram of hexane extract showed minimum number of peaks indicating that polarity of the solvent plays an important role in the extraction process. GC?MS analysis confirmed presence of many important compounds in saffron stamens such as alpha-tocopherol or vitamin E, dibutyl para-cresol, hydroquinone, and certain esters.

Difluorocyclobutylacetylenes as positive allosteric modulators of mGluR5 with reduced bioactivation potential

Schizophrenia is a serious illness that affects millions of patients and has been associated with N-methyl-D-aspartate receptor (NMDAR) hypofunction. It has been demonstrated that activation of metabotropic glutamate receptor 5 (mGluR5) enhances NMDA receptor function, suggesting the potential utility of mGluR5 positive allosteric modulators (PAMs) in the treatment of schizophrenia. Herein we describe the optimization of an mGluR5 PAM by replacement of a phenyl with aliphatic heterocycles and carbocycles as a strategy to reduce bioactivation in a biaryl acetylene chemotype. Replacement with a difluorocyclobutane followed by further optimization culminated in the identification of compound 32, a low fold shift PAM with reduced bioactivation potential. Compound 32 demonstrated favorable brain uptake and robust efficacy in mouse novel object recognition (NOR) at low doses.

Novel selective PDE4 inhibitors. 1. Synthesis, structure-activity relationships, and molecular modeling of 4-(3,4-dimethoxyphenyl)-2H-phthalazin-1-ones and analogues

A number of 6-(3,4-dimethoxyphenyl)-4,5-dihydro-2H-pyridazin-3-ones and a novel series of 4-(3,4-dimethoxyphenyl)-2H-phthalazin-1-ones were prepared and tested on the cGMP-inhibited phosphodiesterase (PDE3) and cAMP-specific phosphodiesterase (PDE4) enzymes. All tested compounds were found to specifically inhibit PDE4 except for pyridazinone 3b, which showed moderate PDE4 (pIC50 = 6.5) as well as PDE3 (pIC50 = 6.6) inhibitory activity. In both the pyridazinone and phthlazinone series it was found that N-substitution is beneficial for PDE4 inhibition, whereas in the pyridazinone series it also accounts for PDE4 selectivity. In the phthalazinone series, the cis-4a,5,6,7,8,8a-hexahydrophthalazinones and their corresponding 4a,5,8,8a-tetrahydro analogues showed potent PDE4 inhibitory potency (10/11c,d: pIC50 = 7.6-8.4). A molecular modeling study revealed that the cis-fused cyclohexa(e)ne rings occupy a region in space different from that occupied by the other fused (un)saturated hydrocarbon rings applied; we therefore assume that the steric interactions of these rings with the binding site play an important role in enzyme inhibition.

A series of halogenated Phenstatin analogs were designed as microtubule destabilizing agent by docking study. It was synthesized within three steps starting from 2-chloro-5-iodobenzoic acid and substituted benzene. All the products were characterized by 1H NMR and 13C NMR spectral analysis, and the stereochemical structure was also confirmed by a single crystal X-ray diffraction crystallographic analysis. The microtubule destabilizing activities were evaluated in vitro with human liver cancer Huh-7 cell line and human lung cancer A549 cell line. Some of the HPAs were achieved IC50 about 5.0 muM against human liver cancer Huh-7 cells. [Figure not available: see fulltext.].

Fenbufen, a new anti inflammatory analgesic: synthesis and structure activity relationships of analogs

100 analogs of fenbufen were prepared and tested using the carrageenan, polyarthritis, and UV erythema anti inflammatory tests and the 2 phenyl 1,4 benzoquinone writhing and inflamed paw pressure analgesic tests. Only 3 retained the same full spectrum of activity as fenbufen: dl 4 (4 biphenylyl) 4 hydroxybutyric acid, dl 4 (4 biphenylyl) 1,4 butanediol, and 4 biphenylacetic acid. Fenbufen had the same spectrum of activity as aspirin, phenylbutazone, and indomethacin in the 5 tests. In addition, dose response derived potencies show fenbufen more potent than aspirin and at least as potent as phenylbutazone in all 5 tests. Two related compounds were generally similar.

Construction of perhydro indol-2-ones by a methoxide catalyzed deacetylation-Michael-aldol cascade

An efficient, stereoselective Michael-aldol cascade for the one-pot construction of the perhydro indol-2-one bicyclic ring system using an acetate protected doubly-activated pyrrole-2-one pro-nucleophile and alpha,beta-unsaturated carbonyl compounds has been developed. Initiated by a methoxide deacetylation in methanol at room temperature, the cascade is easy to perform, stereoselective, efficient and broad in scope to this synthetically relevant structure.
