Hydrogen bond mediated partially miscible poly(N-acryloyl piperidine)/poly(acrylic acid) blend with one glass transition temperature

In this work, we have systematically studied the miscibility and phase structure of a hydrogen-bonded polymer blend composed of short rigid poly(N-acryloyl piperidine) (PAP) and long flexible poly(acrylic acid) (PAA). Ultrathin PAP/PAA blend films with various compositions were prepared by solution-casting method. It was found that the spin-coated blend films had distinct surface features with many protuberant domains that can be extracted by toluene. Composition analysis of the isolated protrusion domains and matrix domains revealed that PAP/PAA blend is a partially miscible system with PAP-rich protrusion phase (dispersed phase) and PAA-rich matrix phase. The hydrogen-bonding interaction between the amide carbonyl of PAP and hydroxyl of PAA (O = C center dot center dot center dot H-O) was found to account for the partial miscibility of these two components. Interestingly, only one positively shifted glass transition temperature (T-g) was detected for this blend. This behavior is very different from other reported partially miscible polymer blends, in which two inward shifted TgS are usually observed. Thermal analysis further disclosed that TgS of PAP-rich dispersed phase and PAA-rich matrix phase are very close to each other, thus merged into one broad T-g presented in the blend. The close TgS of these two phases is attributed to the strong hydrogen-bonding interaction between PAP and PAA, which surpasses the compositional difference between them. At high PAP concentrations (above 60 mol percent), the separation of excess PAP in dispersed phase contributed to the appearance of a second T-g that corresponds to that of PAP. Such phase behavior was further confirmed in the free-standing films of PAP/PAA blends.

Synthesis of some new propanamide derivatives bearing 4-piperidinyl-1,3,4-oxadiazole, and their evaluation as promising anticancer agents

Purpose: To sequentially synthesize piperidine-4-carboxylic acid ethyl ester-appended 1,3,4-oxadiazole hybrids and to evaluate them as anticancer agents. Methods: Ethyl 1-[(4-methylphenyl)sulfonyl]-4-piperidinecarboxylate (1) was synthesized from 4-methylbenzenesulfonylchloride (a) and ethyl 4-piperidinecarboxylate (b) Compound (1) was converted into ethyl 1-[(4-methylphenyl)sulfonyl]-4-piperidine carbohydrazides (2) and 5-{1-[(4-methylphenyl)sulfonyl]-4-piperidinyl}-1,3,4-oxadiazole-2-thiol (3) respectively. A variety of aryl amine (4a-l) were treated with 2-bromopropionylbromide to synthesize an array of propanamide (5a-l). Finally, 5-{1-[(4-methylphenyl)sulfonyl]-4-piperidinyl}-1,3,4-oxadiazole-2-thiol (3) and propanamides (5a-l) were reacted to synthesize target compounds (6a-l) Purity compounds 6a-l was confirmed by spectroscopic techniques like (H-1-NMR), (C-13-NMR) and EI-MS. To determine their anticancer potential, the change in absorbance of mixture and cell line before and after incubation was determined Results: All the compounds 6a-l were successfully synthesized in 73-85 % yield. Compounds 6h, 6j and 6e have low ICso (+/- SD) values of 20 12 +/- 6 20, 10 84 +/- 4 2 and 24 57 +/- 1.62 mu M to act as strong anticancer agents relative to doxorubicin (0.92 +/- 0.1 mu M) used as a reference. Conclusion: The synthesized propanamide derivatives bearing 4-piperidinyl-1,3,4-oxadiazole are potential anticancer agents, but further studies, especially in vivo, are required to ascertain their therapeutic usefulness.

Synthesis of alpha-hydroxyalkyl dehydroazepanes via catalytic enantioselective borylative migration of an enol nonaflate

A Pd-catalyzed borylative migration methodology for cyclic enol perfluorosulfonates was applied to the synthesis of the corresponding 7-membered, azepane ring system. Throughout the optimization, it was shown that the reaction is sensitive to the nitrogen protecting group as well as the type of base and solvent. The resulting cyclic allylboronate reacts stereoselectively with aldehydes for the synthesis of novel alpha-hydroxyalkyl dehydroazepanes in good yield and enantioselectivity over two steps. We highlight the utility of this methodology with an efficient synthesis of the de novo 7-membered ring analogue of the piperidine alkaloid beta-conhydrine. (C) 2018 Elsevier Ltd.

The heterocyclic compound Tempol inhibits the growth of cancer cells by interfering with glutamine metabolism

Tempol (4-hydroxy-2,2,6,6-Tetramethylpiperidine-1-oxyl, TPL), a nitroxide compound, inhibits proliferation and increases the vulnerability of cancer cells to apoptosis induced by cytotoxic agents. However, the molecular mechanism of TPL inhibiting cancer cell proliferation has not been fully understood. In this study, we evaluated the metabolic effect of TPL on cancer cells and explored its cancer therapeutic potential. Extracellular flow assays showed that TPL inhibited cellular basal and maximal oxygen consumption rates of mitochondrial. C-13 metabolic flux analysis showed that TPL treatment had minimal effect on glycolysis. However, we found that TPL inhibits glutamine metabolism by interfering with the oxidative tricarboxylic acid cycle (TCA) process and reductive glutamine process. We found that the inhibitory effect of TPL on metabolism occurs mainly on the step from citrate to alpha-ketoglutarate or vice versa. We also found that activity of isocitrate dehydrogenase IDH1 and IDH2, the key enzymes in TCA, were inhibited by TPL treatment. In xenograft mouse model, TPL treatment reduced tumor growth by inhibiting cellular proliferation of xenograft tumors. Thus, we provided a mechanism of TPL inhibiting cancer cell proliferation by interfering with glutamine utilization that is important for survival and proliferation of cancer cells. The study may help the development of a therapeutic strategy of TPL combined with other anticancer medicines.

Spiro-oxindole Piperidines and 3-(Azetidin-3-yl)-1H-benzimidazol-2-ones as mGlu(2) Receptor PAMs

Starting from two weak mGlu(2) receptor positive allosteric modulator (PAM) HTS hits (4 and 5), a molecular hybridization strategy resulted in the identification of a novel spiro-oxindole piperidine series with improved activity and metabolic stability. Scaffold hopping around the spiro-oxindole core identified the 3(azetidin-3-yl)-1H-benzimidazol-2-one as bioisoster. Medicinal chemistry optimization of these two novel chemotypes resulted in the identification of potent, selective, orally bioavailable, and brain penetrant mGluR(2) PAMs.
