Microreactor Technology as a Tool for the Synthesis of a Glitazone Drug Intermediate

One of the bottlenecks in the pharmaceutical industry is drug production scale-up, which can be performed by microreactor technology. Such an approach was applied to the synthesis of (Z)-5-(4-hydroxybenzylidene)thiazolidine-2,4-dione, a bioactive aromatic heterocyclic compound belonging to the class of glitazones. n-Propanol was the best solvent and piperidine the best catalyst for the batch reaction, which was completed in only 5.5h. In the microreactor, the productivity was almost independent of solvent. The microreactor behaved as a plug-flow reactor and operated at a steady state for ten hours without efficiency loss. The results suggest that microreactors may replace batch reactors in scaling up drug production.

Hyperpolarized long-lived nuclear spin states in monodeuterated methyl groups

Monodeuterated methyl groups may support a long-lived nuclear spin state, with a relaxation time exceeding the conventional spin-lattice relaxation time T-1. Dissolution-DNP (dynamic nuclear polarization) may be used to hyperpolarize such a long-lived spin state. This is demonstrated for the CH2D groups of a piperidine derivative. The polarized sample is manipulated in the ambient magnetic field of the laboratory, without destruction of the hyperpolarized singlet order. Strongly enhanced CH2D signals are observed more than one minute after dissolution, even in the presence of paramagnetic radicals, by which time the NMR signal from the hyperpolarized proton magnetization has completely disappeared.

An Ultrasound-assisted Nanocatalysis: Ag NPs/rGO Nanocomposite Catalyzed One-pot Diastereoselective Synthesis of Functionalized Tetrahydropyridines

Ag NPs decorated reduced graphene oxide (Ag NPs/rGO) composite was synthesized through one-pot protocol involving simultaneous reduction of GO and AgNO3 and characterized by X-ray diffraction, transmission electron microscope, scanning electron microscopy, ultraviolet-visible, Fourier transform infrared, Raman, CV, and energy dispersive X-ray analyses. Results indicated that Ag NPs (similar to 30 nm) were unvaryingly distributed onto the surface of rGO with good dispersion capability that usually lacks in Ag NPs alone. These nanocomposites were exploited to study their catalytic activities toward the one-pot diastereoselective synthesis of functionalized tetrahydropyridines under ultrasonic irradiation (US). The catalytic activity of Ag NPs/rGO was about 22-fold higher under US as compared to conventional method. Antiselectivity, shorter reaction time, excellent yields, simple work-up procedure, and purification of products by non-chromatographic methods were inherent advantages of the protocol. The catalyst was reused up to four runs without an appreciable loss of catalytic activity. [GRAPHICS] .

Appliance of the piperidinyl-hydrazidoureido linker to benzenesulfonamide compounds: Synthesis, in vitro and in silico evaluation of potent carbonic anhydrase II, IX and XII inhibitors

Herein we report on a new series of hydrazidoureidobenzensulfonamides investigated as inhibitors of the cytosolic human (h) hCA I and II isoforms, as well as the transmembrane, tumor-associated enzymes hCA IX and XII. The reported derivatives contain a 4-substituted piperidine fragment in which the hydrazidoureido linker has been involved as spacer between the benzenesulfonamide fragment which binds the zinc ion from the active site, and the tail of the inhibitor. Depending on the substitution pattern at the piperidine ring, low nanomolar inhibitors were detected against hCA II, hCA IX and hCA XII, making the new class of sulfonamides of interest for various pharmacologic applications.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 13925-07-0, you can contact me at any time and look forward to more communication. Product Details of 13925-07-0.

Synthesis, cytotoxic activity, ADMET and molecular docking study of quinoline-based hybrid compounds of 1,5-benzothiazepines

Some alpha,beta-unsaturated ketones 4a-g of 3-acetyl-4-hydroxyquinolin-2(1H)-one were prepared by its reaction with (hetero)aromatic aldehydes with yields of 61-87% using piperidine as a catalyst. These ketones reacted with o-aminothiophenol in the presence of acetic acid to afford a series of new hybrid compounds, quinoline-benzothiazepine, 6a-g. The yields of benzothiazepines 6a-g were 62-85%. All the synthesized compounds 6a-g were screened for their in vitro anticancer activity against human hepatocellular carcinoma HepG2 and squamous cell carcinoma KB cancer lines. Compounds 6d and 6g had the best activity in the series, with IC50 values of 0.25 and 0.27 mu g mL(-1), respectively, against HepG2, and of 0.26 and 0.28 mu M, respectively, against KB cell lines. ADMET properties showed that compounds 6c and 6g possessed drug-likeness behavior. Cross-docking results indicated that residues GLN778(A), DA12(F), and DG13(F) in the binding pocket were potential ligand binding hot-spot residues for compounds 6c and 6g.

Microwave-Assisted Three-Component Domino Synthesis of Polysubstituted 4H-Pyran Derivatives and Their Anticancer Activity

An efficient microwave-assisted one-pot procedure has been proposed for the synthesis of new 4-aryl-6-(methylamino)-5-nitro-2-(1H-pyrrol-2-yl)-4H-pyran-3-carbonitriles by condensation of 3-oxo-3-(1H-pyrrol-2-yl)propanenitrile with (E)-N-methyl-1-(methylsulfanyl)-2-nitroethenamine and substituted benzaldehydes in the presence of a catalytic amount of piperidine using ethanol as a solvent. The transformation occurs via successive Knoevenagel condensation, Michael addition, and intramolecular cyclization. The proposed procedure is advantageous due to its one-pot mode, short reaction time, simple purification by recrystallization, and excellent yields. The product structure was confirmed using various spectroscopic techniques, including IR,H-1 and C-13 NMR, LC/MS, elemental analysis, and single crystal X-ray diffraction study. The synthesized compounds were evaluated for their anticancer activity against 60 different human cancer cell lines in nine cancer panels, and two compounds were found to be potent against different cell lines.

Nonacidic Chemotype Possessing N-Acylated Piperidine Moiety as Potent Farnesoid X Receptor (FXR) Antagonists

Famesoid X receptor (FXR) plays a major role in the control of cholesterol metabolism. Antagonizing transcriptional activity of FXR is an effective means to treat the relevant metabolic syndrome. Some of antagonists so far have the charged functions; however, they may negatively affect the pharmacokinetics. We describe herein a structure activity relationship (SAR) exploration of nonacidic FXR antagonist 6 focusing on two regions in the structure and biological evaluation of nonacidic 10 with the characteristic N-acylated piperidine group obtained from SAR studies. As the robust affinity to FXR is feasible with our nonacidic analogue, 10 is among the most promising candidates for in vivo testing.

Synthesis, characterization and evaluation of novel benzothiazole clubbed chromene derivatives for their anti-inflammatory potential

A series of chromene derivatives (5a-f) were prepared by multistep synthesis process using 2-[3-phenyl prop-2-ene nitrile] 1,3-benzothiazole and dimedone using piperidine as catalyst in ethanol. The reaction was found to proceed via Knoevenagel condensation of aldehydes with benzothiazole, followed by the elimination to afford the 2-(benzo[d]thiazol-2-yl)-3-(aryl)acrylonitrile, which then undergoes Michael addition with 5,5-dimethyl-1,3-cyclohexanedione, followed by intramolecular O-cyclization to give the products. The structures of all novel constructed derivatives were corroborated by elemental analysis and spectral data (FT-IR, H-1-NMR, C-13-NMR and Mass). Subsequently, the compounds were tested for their in-vivo anti-inflammatory activity. This study revealed that these synthesized derivatives tend to have significantly anti inflammatory activity and shall prove as structural templates in the design and development of new anti inflammatory drugs.
