Sever, Belgin;Altintop, Mehlika Dilek;Ciftci, Gulsen Akalin;Ozdemir, Ahmet research published 《 A New Series of Triazolothiadiazines as Potential Anticancer Agents for Targeted Therapy of Non-Small Cell Lung and Colorectal Cancers: Design, Synthesis, In silico and In vitro Studies Providing Mechanistic Insight into Their Anticancer Potencies》, the research content is summarized as follows. Targeted therapies acting on specific mol. targets in cancer cells with better curative efficacy and lower toxicity have come into prominence for the management of nonsmall cell lung cancer (NSCLC) and colorectal cancer (CRC). COX-2 stands out as a plausible target for anticancer agents due to its pivotal role in tumor initiation, progression and invasion. Due to the importance of triazolothiadiazine scaffold in targeted anticancer drug discovery, the aim of this work is the design of new triazolothiadiazines as potential anticancer agents for the targeted therapy of NSCLC and CRC. New triazolo[3,4-b]-1,3,4-thiadiazines (2a-g) were synthesized via the ring closure reactions of 2-bromo-1-arylethanones with 4-amino-5-((5-methoxy-2-methyl-1H-indol-3-yl)methyl)-2,4- dihydro-3H-1,2,4-triazole-3-thione (1), which was obtained via the solvent-free reaction of 5- methoxy-2-methyl-3-indoleacetic acid with thiocarbohydrazide. MTT assay was performed to determine their cytotoxic effects on A549 human lung adenocarcinoma, Caco-2 human colorectal adenocarcinoma and CCD-19Lu human lung fibroblast cells. The most potent compounds were evaluated for their effects on apoptosis, caspase-3, mitochondrial membrane potential, cell cycle, ultrastructural morphol. changes and COX-2 in A549 and Caco-2 cells. In silico docking and Absorption, Distribution, Metabolism and Excretion (ADME) studies were also performed using Schrodinger′s Maestro mol. modeling package. 6-(4-Chlorophenyl)-3-[(5-methoxy-2-methyl-1H-indol-3-yl)methyl]-7H-[1,2,4]triazolo[3,4- b][1,3,4]thiadiazine (2e) was the most potent and selective anticancer agent in this series against A549 and Caco-2 cell lines. Compound 2e induced early apoptosis, caused mitochondrial membrane depolarization and arrested cell cycle at G₀/G₁ phase in A549 cells. On the other hand, compound 2e triggered intrinsic apoptotic pathway involving caspase-3 activation in Caco-2 cells. Compound 2e caused apoptotic morphol. changes in both cancer cell lines. The cytotoxic and apoptotic effects of this compound on CRC were found to be related to its selective COX-2 inhibitory activity. According to mol. docking studies, compound 2e showed good affinity to the active site of COX-2 (PDB code: 4COX). Based on in silico ADME studies, the compound is predicted to possess a favorable ADME profile. According to in vitro and in silico studies, compound 2e was identified as a potential orally bioavailable anticancer agent for COX-2-targeted therapy of CRC.

Sen, Partha Pratim;Roy, Vishal Jyoti;Raha Roy, Sudipta research published 《 Metal-free regioselective bromination of imidazo-heteroarenes: the dual role of an organic bromide salt in electrocatalysis》, the research content is summarized as follows. An electrochem. transformation was represented by demonstrating the dual role of an organic bromide salt, i.e., tetra-n-butylammonium bromide (TBAB), as a brominating agent and as an electrolyte for the regioselective bromination of several imidazo heteroaromatic motifs, e.g., I. Instead of using a transition metal/external oxidant, this methodol. utilized electron holes and electrons by means of anodic oxidation and cathodic reduction to form the desired products in good to excellent yields at ambient temperature The method was simple, environment friendly and compatible with various functional groups. The significance of this sustainable greener bromination technique relies on the fact that the readily available cost-effective electrodes (C(+)/C(-)) could be reused up to forty times without loss of any electrochem. activities. The electro-oxidative method could efficiently be scaled up and can be extended to chlorination as well. Moreover, this electro-synthetic strategy was extrapolated to the domino organo-electrochem. bromination technique for the synthesis of a brominated imidazo heteroaromatic moiety directly starting from substituted 2-bromoacetophenone and 2-aminopyridine by using catalytic amounts of electrolyte.

New push-pull N(9)-alkylated 6-piperidino-2-triazolylpurine and 2-piperidino-6-triazolylpurine derivatives are synthesized, and their optical and optoelectronic properties are comprehensively characterized with exptl. and computational methods. The compounds possess intense violet or blue fluorescence with fluorescence quantum yields of up to 91% in solution and 40% in host-free films. Depending on their structural composition, the compounds have ionization energy in the range of 5.25-6.04 eV, electron affinity of 2.18-3.15 eV, and triplet energy of 2.52-2.95 eV. Due to the presence of hole-transporting purine and electron-transporting triazole fragments, compounds exhibit bipolar charge-transportation ability. Despite the favorable emissive properties of the studied push-pull purines, their electroluminescence in thin films is quenched owing to large current densities that are present even at a moderate driving voltage. This marks application directions related to a predominantly charge-transportation functionality as the most suitable for this compound class.

The profound efficacy, yet associated toxicity of pan-BET inhibitors is well documented. The possibility of an ameliorated safety profile driven by significantly selective (>100-fold) inhibition of a subset of the eight bromodomains is enticing, but challenging given the close homol. Herein, we describe the X-ray crystal structure-directed optimization of a novel weak fragment ligand with a pan-second bromodomain (BD2) bias, to potent and highly BD2 selective inhibitors. A template hopping approach, enabled by our parallel research into an orthogonal template (15, GSK046, I), was the basis for the high selectivity observed This culminated in two tool mols., 20 (GSK620) and 56 (GSK549), which showed an anti-inflammatory phenotype in human whole blood, confirming their cellular target engagement. Excellent broad selectivity, developability, and in vivo oral pharmacokinetics characterize these tools, which we hope will be of broad utility to the field of epigenetics research.

The retinoid X receptors (RXR) are ligand-activated transcription factors involved in multiple regulatory networks as universal heterodimer partners for nuclear receptors. Despite their high therapeutic potential in many pathologies, targeting of RXR has only been exploited in cancer treatment as the currently available RXR agonists suffer from exceptional lipophilicity, poor pharmacokinetics (PK), and adverse effects. Aiming to overcome the limitations and to provide improved RXR ligands, we developed a new potent RXR ligand chemotype based on the nonsteroidal anti-inflammatory drug oxaprozin. Systematic structure-activity relationship anal. enabled structural optimization toward low nanomolar potency similar to the well-established rexinoids. Cocrystal structures of the most active derivatives demonstrated orthosteric binding, and in vivo profiling revealed superior PK properties compared to current RXR agonists. The optimized compounds were highly selective for RXR activation and induced RXR-regulated gene expression in native cellular and in vivo settings suggesting them as excellent chem. tools to further explore the therapeutic potential of RXR.

The synthetic potential of tetrazolo[1,5-a]pyrimidines to obtain new pyrimidine derivatives via click chem. and hydrogenation was reported. Click chem. reactions of trifluoromethyl-tetrazolo[1,5-a]pyrimidines with terminal acetylenes produced unprecedented trifluoromethylated triazolylpyrimidines at excellent yields (84-98%), and one of them was active against all tested microorganisms, with moderate min. inhibitory concentration values (62.5-15.62μg/mL). Hydrogenation was performed using Pd/C-H₂ in MeOH under conventional, photochem., and pressure (5 bar) conditions. Hydrogenation was an excellent method for obtaining 2-amino-6-aryl-4-trifluoromethylpyrimidines and/or 2-amino-6-aryl-4-trifluoromethyltetrahydropyrimidines with a preference for 2-aminopyrimidine formation. Photochem. hydrogenation was the only pathway for reducing aryl-brominated substrates without dehalogenation. The reduction of trifluoromethyl-substituted tetrazolo[1,5-a]pyrimidines furnished 2-amino-6-aryl-4-trifluoromethylpyrimidines instead of the corresponding tetrahydropyrimidines. However, the hydrogenation of non-trifluoromethylated tetrazolo[1,5-a]pyrimidines showed a preference for tetrahydropyrimidine formation.
