Pachl, Petr published the artcileStructure-Based Optimization of Bisphosphonate Nucleoside Inhibitors of Human 5′(3′)-deoxyribonucleotidases, Application of Diethyltrichloromethylphosphonate, the publication is European Journal of Organic Chemistry (2018), 2018(37), 5144-5153, database is CAplus.

Cellular 5′-nucleotidases, enzymes regulating nucleotide/nucleoside pools, are capable of dephosphorylating phosphomonoesters of important nucleoside analog drugs, thus decreasing their therapeutic efficacy. Human cytosolic (cdN) as well as mitochondrial (mdN) variants of this enzyme represent interesting targets for development of inhibitory compounds In this work, bisphosphonate nucleoside derivatives were designed by using a structure-based approach. A second phosphonate group was attached onto a base moiety and by optimization of the linker an increased inhibitor potency towards mdN and cdN was attained. The best compound exhibited inhibition of both enzymes in a nanomolar range, making it the most potent inhibitor of these enzymes prepared to date. In addition, the compounds showed selectivity towards the cdN variant. A series of crystal structures were solved for several inhibitors in the complex with mdN or cdN that provided a structural basis for understanding the inhibition profile of bisphosphonate compounds

Yuan, Hai published the artcileStructural modifications of (1S,3S)-3-amino-4-difluoromethylenecyclopentanecarboxylic acid, a potent irreversible inhibitor of GABA aminotransferase, Quality Control of 866-23-9, the publication is Bioorganic & Medicinal Chemistry Letters (2007), 17(6), 1651-1654, database is CAplus and MEDLINE.

Low brain levels of the inhibitory neurotransmitter γ-aminobutyric acid (GABA) lead to convulsions. Inhibition of GABA aminotransferase increases the concentration of GABA and can terminate the convulsions. Earlier we reported the synthesis of (1S,3S)-3-amino-4-difluoromethylenecyclopentanecarboxylic acid (2), which is 186 times more potent an inactivator of GABA aminotransferase than the epilepsy drug S-vigabatrin. The corresponding dichloromethylene analog of 2 (compound 3) has been made, but it shows only weak reversible inhibition of GABA aminotransferase. However, the tetrazole isostere of 2 (compound 4) has been found to be a time-dependent inactivator of GABA aminotransferase. Although it is 20 times less potent than carboxylic acid 2, it is 2.5 times more potent than S-vigabatrin. A calculation of the Clog P values indicates that 4 is the most lipophilic of the three, being 69 times more lipophilic than 2 and 55 times more lipophilic than S-vigabatrin, indicating potential for improved bioavailability.

Sousa-Pereira, Danilo published the artcileSynthetic (E)-3-phenyl-5-(phenylamino)-2-styryl-1,3,4-thiadiazol-3-ium chloride derivatives as promising chemotherapy agents on cell lines infected with HTLV-1, Product Details of C7H7ClN2S, the publication is Molecules (2020), 25(11), 2537, database is CAplus and MEDLINE.

Synthesis of four compounds belonging to mesoionic class, (E)-3-phenyl-5-(phenylamino)-2-styryl-1,3,4-thiadiazol-3-ium chloride derivatives (5a-d) and their biol. evaluation against MT2 and C92 cell lines infected with human T-cell lymphotropic virus type-1, which causes adult T-cell leukemia/lymphoma (ATLL), and non-infected cell lines (Jurkat) are reported. The compounds were obtained by convergent synthesis under microwave irradiation and the cytotoxicity was evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays. Results showed IC50 values of all compounds in the range of 1.51-7.70μM in HTLV-1-infected and non-infected cells. Furthermore, it was observed that 5b could induce necrosis after 24 h for Jurkat and MT2 cell lines. The exptl. (fluorimetric method) and theor. (mol. docking) results suggested that the mechanism of action for 5b could be related to its capacity to intercalate into DNA. Moreover, the preliminary pharmacokinetic profile of the studied compounds (5a-d) was obtained through human serum albumin (HSA) binding affinity using multiple spectroscopic techniques (CD, steady-state and time-resolved fluorescence), zeta potential and mol. docking calculations The interaction HSA:5a-d is spontaneous and moderate (Ka ~104 M-1) via a ground-state association, without significantly perturbing both the secondary and surface structures of the albumin in the subdomain IIA (site I), indicating feasible biodistribution in the human bloodstream.

A highly effective method to synthesize dialkyl peroxides from alkyl hydroperoxides and alkyl bromides in a liquid-liquid-liquid system using tetraalkylammonium salts as phase-transfer catalysts is reported. This process was conducted in the presence of highly concentrated aqueous KOH solutions and cyclohexane as an organic solvent. In a liquid-liquid-liquid system, the phase-transfer catalyst forms an insoluble third-liquid phase between the organic and aqueous phases that enables the catalyst to be recycled multiple times. Dialkyl peroxides were obtained in high yields and with 100% selectivity.

A reproducible and highly accurate spectrophotometric determination of decamethoxine (I) [38146-42-8] consisted of adding eosin  [17372-87-1] 0.5 (10^-3 mol/L), EtOH 3, and pH 2.8 citrate buffer 5 mL to 75-100 μg I and making the volume to 25 mL with H₂O. The absorbance is measured at 555 nm. NaCl does not interfere with I determination in diluted solutions (0.01-0.05%) containing 0.9% NaCl. The Beer’s law was observed at 0.3-4 μg I/mL. Eosin and I form a 1:2 complex (5-10 min). The addition of 10-20% EtOH increased the stability of the solutions and also the absorbance. At >20% EtOH, the absorbance of the complex decreased. The absorbance is stable for >1 h. At pH 2-3.5 the solution has the highest stability.
