Discovery of 5-Phenoxy-2-aminopyridine Derivatives as Potent and Selective Irreversible Inhibitors of Bruton’s Tyrosine Kinase

As a member of the tyrosine protein kinase Tec (TEC) family, Bruton’s tyrosine kinase (BTK) is considered a promising therapeutic target due to its crucial roles in the B cell receptor (BCR) signaling pathway. Although many types of BTK inhibitors have been reported, there is an unmet need to achieve selective BTK inhibitors to reduce side effects. To obtain BTK selectivity and efficacy, we designed a novel series of type II BTK inhibitors which can occupy the allosteric pocket induced by the DFG-out conformation and introduced an electrophilic warhead for targeting Cys481. In this article, we have described the structure-activity relationships (SARs) leading to a novel series of potent and selective piperazine and tetrahydroisoquinoline linked 5-phenoxy-2-aminopyridine irreversible inhibitors of BTK. Compound 18g showed good potency and selectivity, and its biological activity was evaluated in hematological tumor cell lines. The in vivo efficacy of 18g was also tested in a Raji xenograft mouse model, and it significantly reduced tumor size, with 46.8% inhibition compared with vehicle. Therefore, we have presented the novel, potent, and selective irreversible inhibitor 18g as a type II BTK inhibitor.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 111974-74-4 help many people in the next few years. HPLC of Formula: C17H19Cl2N3S.

The piperazine compound ASP activates an auxin response in Arabidopsis thaliana

BackgroundAuxins play key roles in the phytohormone network. Early auxin response genes in the AUX/IAA, SAUR, and GH3 families show functional redundancy, which makes it very difficult to study the functions of individual genes based on gene knockout analysis or transgenic technology. As an alternative, chemical genetics provides a powerful approach that can be used to address questions relating to plant hormones.ResultsBy screening a small-molecule chemical library of compounds that can induce abnormal seedling and vein development, we identified and characterized a piperazine compound 1-[(4-bromophenoxy) acetyl]-4-[(4-fluorophenyl) sulfonyl] piperazine (ASP). The Arabidopsis DR5::GFP line was used to assess if the effects mentioned were correlated with the auxin response, and we accordingly verified that ASP altered the auxin-related pathway. Subsequently, we examined the regulatory roles of ASP in hypocotyl and root development, auxin distribution, and changes in gene expression. Following ASP treatment, we detected hypocotyl elongation concomitant with enhanced cell elongation. Furthermore, seedlings showed retarded primary root growth, reduced gravitropism and increased root hair development. These phenotypes were associated with an increased induction of DR5::GUS expression in the root/stem transition zone and root tips. Auxin-related mutants including tir1-1, aux1-7 and axr2-1 showed phenotypes with different root-development pattern from that of the wild type (Col-0), and were insensitive to ASP. Confocal images of propidium iodide (PI)-stained root tip cells showed no detectable damage by ASP. Furthermore, RT-qPCR analyses of two other genes, namely, Ethylene Response Factor (ERF115) and Mediator 18 (MED18), which are related to cell regeneration and damage, indicated that the ASP inhibitory effect on root growth was not attributable to toxicity. RT-qPCR analysis provided further evidence that ASP induced the expression of early auxin-response-related genes.ConclusionsASP altered the auxin response pathway and regulated Arabidopsis growth and development. These results provide a basis for dissecting specific molecular components involved in auxin-regulated developmental processes and offer new opportunities to discover novel molecular players involved in the auxin response.

Advancement of ammonia-based post-combustion CO(2 )capture technology: Process modifications

Aqueous ammonia (NH3)-based capture process has the potential to simultaneously remove NOx/SO2/CO2 pollutants at low cost, but conventional NH3-based process suffers high NH3 slip, high energy consumption and high capital investment. The present study aims to advance the NH3-based scrubbing technology to overcome these technical issues. We used inter-cooled CO2 absorber to mitigate the NH3 emission and enhance CO2 absorption, while employed advanced flash stripper configuration to significantly decrease the absorbent regeneration duty. We also proposed an effective NOx/SO2 removal process by utilizing the slipped NH3 for multi-pollutant emission control. A validated model was used to gain insight into the techno-economic performance of this advanced NH3-based NOx/SO2/CO2 removal process, and important process parameters such as absorption temperature, NH3 concentration and flue gas NOx/SO2 concentrations were investigated in detail. The results indicate that the advanced NH3 process enabled great capital saving by 23% and energy saving by 42%, resulting in a low CO2-avoided cost of USS44.3/t CO2, which is 42.8% lower than the baseline NH3 process.

Design and synthesis of purine connected piperazine derivatives as novel inhibitors of Mycobacterium tuberculosis

A series of novel purine linked piperazine derivatives were synthesized to identify new, potent inhibitors of Mycobacterium tuberculosis. The compounds were designed to target MurB disrupting the biosynthesis of the peptidoglycan and exert antiproliferative effects. The first series of purine-2,6-dione linked piperazine derivatives were synthesized using an advanced intermediate 1-(3,4-difluorobenzyl)-7-(but-2-ynyl)-3-methyl-8-(piperazin-1-yl)-1H-purine-2,6(3H,7H)-dione hydrochloride (6) which was coupled with varied carboxylic acid chloride derivatives. Following this piperazine linked derivatives were also synthesized from 6 using diverse isocyanate partners. The anti-mycobacterial activity of the analogues was tested against Mycobacterium tuberculosis H37Rv which revealed a cluster of six analogues (11, 24, 27, 32, 33 and 34), possessed promising activity. In comparison, a set of these new compounds possessed greater potencies relative to current drugs used in the clinic such as Ethambutol. These results were also correlated with computational molecular docking analysis, providing models for strong interactions of the inhibitors with MurB providing a template for the future development of preclinical agents against Mycobacterium tuberculosis.

Enhanced oxidative degradation of norfloxacin using peroxymonosulfate activated by oily sludge carbon-based nanoparticles CoFe2O4/OSC

In this study, oily sludge (OS) was pyrolyzed into an environmentally friendly OS carbon (OSC) material, which was used as the carrier of CoFe2O4 nanoparticles to prepare a heterogeneous catalyst CoFe2O4/OSC, and it was used to catalyze the degradation of norfloxacin (NFC) by peroxymonosulfate (PMS). X-ray diffraction (XRD) and transmission electron microscope (TEM) characterization results show that CoFe2O4/OSC had a spinel structure under high temperature pyrolysis conditions. The effects of initial pH, PMS dosage, catalyst dosage, and temperature on NFC degradation efficiency were also studied. Under a temperature of 25 degrees C, an initial pH of 7, a catalyst amount of 0.5 g/L, and a PMS dosage of 0.8 mM, the reaction rate constant reached 0.051 min(-1), and the degradation efficiency and total organic carbon of NFC reached 90.8% and 62%, respectively, within 60 min. Trace amounts of Co and Fe ions were leached from the system (both less than 30 mu g/L). After ten cycles, the degradation efficiency of NFC decreased to 69.8%. Radical quenching experiments, electron paramagnetic resonance, and X-ray fluorescence spectroscopy characterization proved that free-radical ((OH)-O-center dot, SO4 center dot-, and O-2(center dot-)) and nonradical (O-1(2)) active species were present in the system. Moreover, the CoFe2O4/OSC/PMS system involved the participation of two pairs of redox couples (Fe(II)/Fe(III) and Co(III)/Co(II)). Results from matrix-assisted laser desorption ionization time-of-flight mass spectrometry and ion chromatography proved that the main oxidation pathways of NFC were formed through the fragmentation of heterocycles, defluorination of benzene rings, decarboxylation reactions, and piperazine ring-opening process. At the same time, NFC was eventually oxidized to fluoride. This study provides potential for the resource utilization of OS and the application of sludge-type catalysts in PMS-activated oxidation systems.

A simple thermodynamic tool for assessing energy requirements for carbon capture using solid or liquid sorbents

Carbon capture and sequestration is known to be energy intensive and will result in 20-30 % reduction in net output of a power plant. However, a simple thermodynamic tool is currently unavailable for assessing the work of CO2 separation using a given solid or liquid sorbent. This paper provides rigorous yet simple framework of equivalent work to assess the energy requirement for CO2 capture using liquid amines or solid adsorbents. First, the theoretical minimum work is determined by assuming that each step in the sorption – desorption cycle is thermodynamically reversible. Then, irreversible heat transfer losses are added to calculate total work for the actual process. The model provides useful insights into the sorbent and process selection. The minimum work for reversible separation can be calculated merely from CO2 sorption equilibria at ambient temperature without requiring laborious data or complex models. A sorbent with low ab/adsorption heat does require less thermal energy, but this thermal energy is required at a higher temperature. Thus, contrary to conventional thinking, the equivalent work is not reduced. The irreversible heat transfer losses for the amines are mostly dictated by the amine’s circulation rate which will be minimized by using amines with the highest CO2 capacity. On an energy requirement basis, the solid adsorbent based processes cannot compete with amines because practical methods of heat recuperation from the hot regenerated adsorbent are unavailable. Without heat recuperation, the solid adsorbent processes will be attractive only if their capital advantage outweighs their higher energy use.

Novel piperazine-2,5-dione analogs bearing 1H-indole: Synthesis and biological effects

In this work, a series of novel piperazine-2,5-dione derivatives bearing indole analogs (2a-2q) was designed and synthesized. The synthesized compounds were characterized by IR, H-1 NMR, C-13 NMR spectroscopy, and ESI-MS. They were then evaluated for their anti-depressant, anti-inflammatory, and analgesic activities in vivo. The experimental results revealed that all the compounds showed clear anti-depressant, anti-inflammatory, and analgesic effects at a dose of 10 mg/kg. Among them, compounds 2e and 2q exhibited the best anti-depressant effects (the percent decreases in the duration of immobility were 70.2% and 71.2%, respectively), which were similar to that of fluoxetine (67.9%) in the forced swim test. Additionally, compounds 2e and 2q also displayed good anti-inflammatory and analgesic activities. Literature reports have highlighted the anti-inflammatory and analgesic effects of anti-depressant drugs, suggesting that they may have a similar mechanism of action. Therefore, further studies to investigate the possible mechanisms of action of compounds 2e and 2q are warranted.

Activating Chalcogen Bonding (ChB) in Alkylseleno/Alkyltelluroacetylenes toward Chalcogen Bonding Directionality Control

Activation of a deep electron-deficient area on chalcogen atoms (Ch=Se, Te) is demonstrated in alkynyl chalcogen derivatives, in the prolongation of the (C equivalent to)C-Ch bond. The solid-state structures of 1,4-bis(methylselenoethynyl)perfluorobenzene (1Se) show the formation of recurrent chalcogen-bonded (ChB) motifs. Association of1Seand the tellurium analogue1Tewith 4,4 ‘-bipyridine and with the stronger Lewis base 1,4-di(4-pyridyl)piperazine gives 1:1 co-crystals with 1D extended structures linked by short and directional ChB interactions, comparable to those observed with the corresponding halogen bond (XB) donor, 1,4-bis(iodoethynyl)-perfluorobenzene. This alkynyl approach for chalcogen activation provides the crystal-engineering community with efficient, and neutral ChB donors for the elaboration of supramolecular 1D (and potentially 2D or 3D) architectures, with a degree of strength and predictability comparable to that of halogen bonding in iodoacetylene derivatives.

p-Phenylenediamine-grafted multi-walled carbon nanotubes as a hydrophilic modifier in thin-film nanocomposite membrane

In this paper, an efficient thin-film nanocomposite (TFN) membrane was synthesized by interfacial polymerization and used for water desalination. Piperazine (PIP) and trimesoyl chloride were used as monomers, andp-phenylenediamine-grafted multi-walled carbon nanotube (p-PDA-MWCNT) was used as a hydrophilic modifier to enhance the performance of the polysulfone nanofiltration membrane. In order to characterize the synthesizedp-PDA-MWCNTs, Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis and electron-dispersive spectroscopy were used. In order to enhance the performance of the membrane, different concentrations ofp-PDA-MWCNTs (0.01, 0.02, 0.04, 0.05 and 0.075 wt%) were added to the PIP solution to preparep-PDA-MWCNTs-embedded membranes. To check the performance of the modified membrane, solutions of 1000 mg L-1Na2SO4, MgSO4, NaCl and CaCl(2)were tested. The results show that TFN-modified membrane provides excellent water permeability and also salt rejection in the presence of 0.02 wt%p-PDA-MWCNTs which shows superior improvement in TFN membrane.
