Novel hydroxyl-substituted double Schiff-base 4-piperidone/cyclohexanone derivatives, and , were synthesized and fully characterized by 1H NMR, IR and elemental anal. The cytotoxicity against human carcinoma cell lines A549, SGC7901, HePG2, HeLa, K562, THP-1 and non-malignant LO2 cell lines were evaluated. The results showed 4-piperidinone derivatives displayed better cytotoxicity than cyclohexanone derivatives, especially for 3,4,5-trihydroxyphenyl-substituted BAP . The western blot and flow cytometry results proved can effectively promote cell apoptosis through up-regulating Bax protein and down-regulating Bcl-2 protein expression. Mol. docking modes showed that could reasonably bind to the active site of Bcl-2 protein through strong intermol. hydrogen bonds and significant hydrophobic effect. In vivo, can effectively suppress the growth of HepG2 xenografts without apparent body weight changes.

The article was titled 《Self-aggregating cationic-chains enable alkaline stable ion-conducting channels for anion-exchange membrane fuel cells》, and you may find the article in Journal of Materials Chemistry A: Materials for Energy and Sustainability.Computed Properties of C6H11NO The information in the text is summarized as follows:

Precise manipulation of the polyelectrolyte self-assembly process, to form the desired microstructure with ion-conducting channels, is of fundamental and technol. importance to many fields, such as fuel cells, flow batteries and electrodialysis. To fabricate anion exchange membranes (AEMs) with highly conductive and alk. stable ion-conducting channels, we hereby report a strategy for designing self-aggregating side chains with optimized alk. stability, by inserting dipolar ethylene oxide (EO) spacers in the cationic side chain. Simulation and nano-scale microscopy analyses verify the self-assembly process of the flexible side chain with cation-dipole interaction to construct interconnected ionic highways for fast water and ion transportation. The resulting O-PDQA AEM exhibits higher hydroxide conductivity (106 mS cm-1 at 80 °C) and a competitive peak power d. (1.18 W cm-2 at 70 °C) in alk. H2/O2 single-cell fuel cells. Moreover, O-PDQA shows excellent alk. stability with over 96% conductivity retention after storage in 2 M NaOH solution at 80 °C for 1080 h. This new concept of introducing dipolar moieties in the cationic side chain can accelerate the development of technologies that involve polyelectrolytes.

Safety of 1-Methyl-4-piperidoneIn 2020 ,《Construction and bioimaging application of novel indole heptamethine cyanines containing functionalized tetrahydropyridine rings》 appeared in Journal of Materials Chemistry B: Materials for Biology and Medicine. The author of the article were Ma, Xiaoxie; Zhang, Chen; Feng, Lan; Liu, Sheng Hua; Tan, Ying; Yin, Jun. The article conveys some information:

IR780 as a com. available dye with near-IR emission has been extensively applied in fluorescent probes and bioimaging. In this work, to further intensify the optical behavior, a tetrahydropyridine ring was used to replace the cyclohexene ring at the center of IR780, forming a cyanine dye Cy-NH with near-IR emission. Photophys. properties demonstrated that Cy-NH exhibits good optical performance. In particular, Cy-NH contains two functional reaction sites (e.g. Cl and NH sites on the tetrahydropyridine ring) and can be used to construct functional cyanine dyes. Investigation on imaging showed that these cyanines can be used as near-IR fluorescent imaging agents in living cells and in vivo. In addition to this study using 1-Methyl-4-piperidone, there are many other studies that have used 1-Methyl-4-piperidone(cas: 1445-73-4Safety of 1-Methyl-4-piperidone) was used in this study.

The article was written by Abdallah, Muhammad Salihu; Mustafa, Muskhazli; Nallappan, Meenakshii A. P.; Choi, Sangho; Paik, Jin-Hyub; Rusea, Go. The article contains the following contents:

Gallic acid and catechin are the most abundant phenolic and flavonoid contents found in all plant extracts The contents and the bioassay-guided fractionating substances of the Sclerocarya birrea (A. Rich) Hochst (Anacardiaceae) fraction played vital roles. The goals of the study were to determine the contents of some useful medicinal plants and the bioassay guided fractionation substances of S. birrea fraction compounds capable of acting against Salmonella isolate using LC-MS/LC-HRMS (Dionex ultimate 3000 RS UPLC with Thermo Scientific Q Exactive Orbitrap Hybrid Tandem Mass Spectrometer). The Folin-Ciocalteu reagent procedure and flavonoid content determination were conducted spectrophotometrically. Bioassay-guided fractionation, chronol. partitioning, and screening of the antibacterial action against Salmonella typhi were performed. The Et acetate fraction extracts of S. birrea stem (bark) extract were analyzed using LC-MS/LCHRMS. The gallic acid content increased tremendously in Vachellia nilotica (L.) P.J.H. Hurter and Mabb (Fabaceae) pod extracts with curve fitting (R2 = 0.9958). Catechin content increase was significantly increased in S. birrea stem (bark) extracts followed by that of V. nilotica pod extracts with curve fitting (R2 = 0.9993); they were all significantly different in the Guiera senegalensis J.F. Gmel. and the Leptadenia lanceolata (Poir.) Goyder leaves extracts at p value <0.0001. Subsequently, 10 mg/mL of S. birrea stem (bark) Et acetate fraction extract was the MIC, where no MBC was recorded and susceptible to the pos. control with the highest inhibition zone, followed by the Et acetate fraction extract at 10 mg/mL (9.7 ± 0.0) at Turkey's p < 0.0001. Vidarabine is one of the novel compounds, specifically having antimicrobial actions, found in the S. birrea stem (bark).

《HDAC6 inhibitor accelerates wound healing by inhibiting tubulin mediated IL-1β secretion in diabetic mice》 was written by Karnam, Kalyani; Sedmaki, Kavitha; Sharma, Pravesh; Routholla, Ganesh; Goli, Sriharshini; Ghosh, Balaram; Venuganti, Venkata Vamsi Krishna; Kulkarni, Onkar Prakash. Application of 1445-73-4 And the article was included in Biochimica et Biophysica Acta, Molecular Basis of Disease in 2020. The article conveys some information:

Delayed wound healing in diabetes is characterized by sustained activation of inflammasome and increased expression of IL-1β in macrophages. Identification and validation of novel pathways to regulate IL-1β expression will provide therapeutic targets for diabetic wounds. Here we report sustained over-expression of histone deacetylase 6 (HDAC6) in wounds of diabetic mice and its role in delayed wound healing. Topical application of HDAC6 inhibitor; Tubastatin A (TSA) gel promoted the wound healing in diabetic mice. TSA hydrogel reduced the infiltration of neutrophils, T-cells and macrophages in the early phase of wound healing. TSA treatment promoted the wound healing by inducing collagen deposition, angiogenesis (CD31) and fibrotic factors (TGF-β1) in the late phase of healing. Protein anal. of the diabetic wounds treated with TSA showed increased acetylated α-tubulin and decreased levels of mature IL-1β with no significant effect on the expression of pro-IL-1β, pro-caspase-1 and active caspase-1. In in vitro assays, macrophages exhibited upregulation of HDAC6, IL-1β and downregulation of IL-10 upon stimulation with high glucose and LPS. TSA inhibited the IL-1β secretion and promoted IL-10 in stimulated macrophages with high glucose and LPS. Further investigations showed that TSA inhibits IL-1β release by inhibiting tubulin dependent lysosomal exocytosis without affecting its transcription and maturation. Nocodazole (known acetylation inhibitor) pre-treatment inhibited TSA effect on IL-1β secretion in high glucose stimulated macrophages. Overall, our findings indicate that sustained HDAC6 expression in diabetic wounds contributes to impaired healing responses and HDAC6 may represent a new therapeutic target for diabetic wounds.

In 2019,Journal of Organometallic Chemistry included an article by Lahiji, Fatemeh Khadem; Ariafard, Alireza. Category: piperidines. The article was titled 《Revisiting the mechanism of acetylenic amine N-Oxide rearrangement catalyzed by Gold(I) complexes from a DFT perspective》. The information in the text is summarized as follows:

In this study, we used d. functional theory (DFT) to reinvestigate the mechanism proposed by Houk and Zhang et al. (J. Am. Chem. Soc. 2012, 134, 1078) for piperidinone formation through rearrangement of an acetylenic amine N-oxide catalyzed by phosphine gold(I) complexes. For this rearrangement, the C-C coupling was proposed to be the rate-determining step with activation energy as high as 35.8 kcal/mol. Such a barrier seems inconsistent with the fact that the actual reaction proceeds under very mild conditions (0 °C, 1 h, in CH2Cl2). In the original report, it was proposed that the C-C coupling takes place via a mechanism which we called “”front-side addition””. Interestingly, we found that the C-C coupling step becomes energetically more favorable if it occurs via another mechanism called “”back-side addition””. We explored the effect of different phosphine ligands on all conceivable steps of the catalytic reaction and found that while the other steps are not highly sensitive to the phosphine identity, the C-C coupling one shows a considerable degree of dependency; the more electron-donating the phosphine ligand, the lower the rate-limiting step barrier.

Breast cancer is the most common cancer of women-it affects more than 2 million women worldwide. PTP1B phosphatase can be one of the possible targets for new drugs in breast cancer therapy. In this paper, we present new curcumin derivatives featuring a 4-piperidone ring as PTP1B inhibitors and ROS inducers. We performed cytotoxicity anal. for twelve curcumin derivatives against breast cancer MCF-7 and MDA-MB-231 cell lines and the human keratinocyte HaCaT cell line. Furthermore, because curcumin is a known antioxidant, we assessed antioxidant effects in its derivatives For the most potent cytotoxic compounds, we determined intracellular ROS and PTP1B phosphatase levels. Moreover, for curcumin and its derivatives, we performed real-time microscopy to observe the photosensitizing effect. Finally, computational anal. was performed for the curcumin derivatives with an inhibitory effect against PTP1B phosphatase to assess the potential binding mode of new inhibitors within the allosteric site of the enzyme. We observed that two tested compounds are better anticancer agents than curcumin. Moreover, we suggest that blocking the -OH group in phenolic compounds causes an increase in the cytotoxicity effect, even at a low concentration Furthermore, due to this modification, a higher level of ROS is induced, which correlates with a lower level of PTP1B.
