Four-component stereoselective synthesis of tetracyano-substituted piperidines

A novel four-component stereoselective synthesis of polysubstituted piperidines is reported. The Knoevenagel-Michael-Mannich cascade of two equivalents of aromatic aldehydes, formaldehyde, two equivalents of malononitrile and ammonium acetate provides convenient access to the 2,6-diaryl-3,3,5,5-tetracyanopiperidines in good to excellent yields Ammonium acetate plays a role both as a catalyst and as a nitrogen source. The formation of products is highly stereoselective. Structures of the synthesized compounds were confirmed by H-1 NMR, C-13 NMR, IR, elemental analysis and mass spectral studies. 2,6-diphenylpiperidine-3,3,5,5-tetracarbonitrile was characterized by X-ray diffraction.

Preparation of 3-hydroxyisoquinoline-1,4-dione and piperidine-2,5-dione under cerium photocatalysis from alkyne-tethered N-alkoxylamide with O-2

A facile preparation of 3-hydroxylisoquinolin-1, 4-diones and piperidine-2,5-dione from alkyne-tethered amide is reported under cerium photocatalysis and O-2 balloon. The reaction works well with a broad reaction scope and reaction efficiency. Mechanism studies indicate that 3-hydroxylpyrrolidin-2-one-containing alpha-ketol radical species serves as a possible key intermediate, and the final product is attributed to a formal N-centered radical initiated [2 + 2] cyclization and alpha-ketol rearrangement. Interestingly, divergence towards C-N bond migration and C-C bond migration is reached in this radical a-ketol rearrangement.

Complete inhibition of fetal movement in the day 40 pregnant goat model by the piperidine alkaloid anabasine but not related alkaloids

Four chemically similar alkaloids, anabasine, anabaseine, epibatidine and dimethylphenylpiperazinium (DMPP), are potent nicotinic acetylcholine receptor agonists of fetal muscle nicotinic acetylcholine receptors in human TE-671 cells. Based on results with these cells, we hypothesized that the alkaloids would completely inhibit ultrasound-monitored fetal movement in a goat model. Different, single doses of anabasine, anabaseine, epibatidine, DMPP, or saline control were administered I.V. to pregnant goats on day 40 of gestation and the number of fetal movements per 5 min sample was measured by ultrasound at times 0, 0.5, 1, 2, 4 and 8 h. The differences among does in fetal movements were more consistent at dosing and following recovery for doses of anabasine above 0.125 mg/kg compared to the other compounds and dosages. Anabasine actions were dose-dependent with an IC50 value of similar to 0.1 mg/kg, and, at a dose of 0.8 mg/kg, completely inhibited fetal movement for 1.5 h after dosing. Anabaseine, epibatidine, and DMPP failed to completely inhibit fetal movement in day 40 pregnant goats at doses predicted to be effective. These results suggest that while experiments with TE-671 cells provide valuable information and predictions of the actions of plant alkaloids on fetal movement, in vivo experiments are still required in order to determine the ability of an alkaloid to inhibit fetal movement in livestock species. Moreover, other pharmacological properties such as receptor differences between mammalian species and differences in the pharmacokinetic properties of the alkaloids also are likely to weaken teratologic predictions based solely on the in vitro data.

Advances in Spirocyclic Hybrids: Chemistry and Medicinal Actions

The present review deals with the progress in medicinal chemistry of spirocyclic compounds, a wider class of natural and synthetic organic molecules, defined as a hybrid of two molecular entities covalently linked via a unique tetrahedral carbon. This spiro central carbon confers to the molecules a tridimensional structurally oriented framework, which is found in many medicinally relevant compounds, a well-known example is the antihypertensive spironolactone. Various bioactive natural products possess the privileged spiro linkage and different chemo-types thereof become synthetically accessible since the 20th century. Actually, there has been a growing interest in the synthesis of heterocyclic hybrids gathered via a spiro carbon. Most of these combinations are two moieties in one scaffold being able to interfere with biological systems through sequential mechanisms. Spirocyclic hybrids containing indole or oxindole units are compounds exhibiting higher interaction with biological receptors by protein inhibition or enzymatic pathways and their recognition as promising anticancer agents in targeted chemotherapy is foreseen. These specific, low-weight and non-complex spirocyclic hybrids are potent inhibitors of SIRT1, Mdm2-p53 and PLK4, showing affinity for anaplastic lymphoma kinase (ALK) receptor. They are also known as excellent DNA binders, acting on cellular division by arresting the cell cycle at different phases and inducing apoptotic cell death. A structural diversity of spirocyclic hybrids has proved neuroprotective effects, anti-HIV, antiviral and antibacterial activities. Hundred of papers are mentioned in this review underlying chemical issues and pharmacological potencies of spiro compounds, which render them impressive synthetic hits for innovative drug conception.

2D & 3D-QSAR Study on Novel Piperidine and Piperazine Derivatives as Acetylcholinesterase Enzyme Inhibitors

Introduction: Acetylcholinesterase enzyme (AChE) is the main target in Alzheimer’s disease therapy and designing of novel AChE inhibitors is a great deal of attention. Methods: In this study, 2D-QSAR and 3D-QSAR models were generated using stepwise multiple linear regressions (SW-MLR) and comparative molecular field analysis (CoMFA) respectively. Results: It was found that CoMFA model with r(2) of 0.947 for the training set and r(2) of 0.816 for the test set is more favorable than model which is established by SW-MLR method with r(2) = 0.825 and r2pred = 0.778 in 2D-QSAR. Conclusion: In addition, obtaining models were validated by cross validation with cut off values of q(2) > 0.5 and r(2) pred > 0.6.

Chlorination of 2-substituted 1-hydroxyindoles

Chlorination of 1-hydroxyindole-5,6-dicarbonitriles and 1-hydroxypyrrolo[3,4-f]indole-5,7(1H,6H)-diones with N-chlorosuccinimide afforded previously unknown 3,3-dichloro-3Hindole 1-oxides instead of the expected 3-chloro-1-hydroxyindoles. The latter, however, were prepared in good yields by treatment of the above 3,3-dichloro-3H-indole 1-oxides with piperidine in ethanol. Reduction of 3,3-dichloro-5,6-dicyano-3H-indole 1-oxides with Zn in AcOH yielded the corresponding 3-chloroindole-5,6-dicarbonitriles.
