We report here structural development of N-(4-phenoxyphenyl)benzamide derivatives as novel SPAK (STE20/SPS1-related proline/alanine-rich kinase) inhibitors. Abnormal activation of the signal cascade of with-no-lysine kinase (WNK) with OSR1 (oxidative stress-responsive kinase 1)/SPAK and NCC (NaCl cotransporter) results in characteristic salt-sensitive hypertension, and therefore inhibitors of the WNK-OSR1/SPAK-NCC cascade are candidates for antihypertensive drugs. Based on the structure of lead compound 2, we examined the SAR of N-(4-phenoxyphenyl)benzamide derivatives, and developed compound 20l as a potent SPAK inhibitor. Compounds 201 is a promising candidate for a new class of antihypertensive drugs.

Fujii, Shinya published the artcileStructural Development of Salicylanilide-Based SPAK Inhibitors as Candidate Antihypertensive Agents, Recommanded Product: 3-Chloro-4-fluoronitrobenzene, the publication is ChemMedChem (2021), 16(18), 2817-2822, database is CAplus and MEDLINE.

Hypertension is an important target for drug discovery. We have focused on the with-no-lysine kinase (WNK)-oxidative stress-responsive 1 (OSR1) and STE20/SPS1-related proline-alanine-rich protein kinase (SPAK)-NaCl cotransporter (NCC) signal cascade as a potential target, and we previously developed a screening system for inhibitors of WNK-OSR1/SPAK-NCC signaling. Herein we used this system to examine the structure-activity relationship (SAR) of salicylanilide derivatives as SPAK kinase inhibitors. Structural design and development based on our previous hit compound, aryloxybenzanilide derivative I, and the veterinary anthelmintic closantel (II) led to the discovery of compound III as a potent SPAK inhibitor with reduced toxicity. Compound III decreased the phosphorylation level of NCC in mouse kidney in vivo, and appears to be a promising lead compound for a new class of antihypertensive drugs.

Sergeev, Pavel G. published the artcileConstruction of 6-Aminopyridazine Derivatives by the Reaction of Malononitrile with Dichloro-Substituted Diazadienes, Recommanded Product: 1-(2-Chloro-5-(trifluoromethyl)phenyl)hydrazine, the publication is European Journal of Organic Chemistry (2020), 2020(31), 4964-4971, database is CAplus.

The reactions of 4,4-dichloro-1,2-diazabuta-1,3-dienes with malononitrile resulted in an efficient approach to highly functionalized 6-aminopyridazine derivatives isolated in up to 98%. The process was found to provide straightforward access to the interesting type of nitrogen-containing heterocycles with an exocyclic double bond. Furthermore, the possibility of subsequent functionalization of the obtained compounds via intramol. cyclization was demonstrated. As a result, condensed azaheterocycles can be prepared very efficiently in one-pot and tandem versions. Finally, the influence of structural features of all synthesized compounds on their absorption characteristics in the UV/Vis-range is also investigated.

Balinge, Kamlesh Rudreshwar published the artcileFacile access to polymer supported zinc-salen complex: highly efficient heterogeneous catalyst for synthesizing hydantoins, thiohydantoins and Schiff bases in aqueous medium, Application In Synthesis of 3696-23-9, the publication is Research on Chemical Intermediates (2018), 44(3), 2075-2097, database is CAplus.

The synthesis of polymer supported zinc-salen complex (PS-Zn-salen) is described. The mononuclear zinc(II)-salen complex was characterized by Fourier-transform NMR spectroscopy, energy-dispersive X-ray spectroscopy, Fourier transform IR spectrophotometry (FT-IR), thermogravimetric anal., SEM, surface area and pore size distribution by Brunauer-Emmett-Teller. The synthesized PS-Zn-salen complex used as a recyclable heterogeneous catalyst for the efficient synthesis of hydantoins, thiohydantoins and Schiff bases in an aqueous medium. The isolated yields of hydantoins, thiohydantoins and Schiff bases achieved up to 89, 95 and 94%, resp. In spite of conventional heterogeneous catalysts, current PS-Zn-salen complex shows thermal stability up to 280 °C. Moreover, the catalyst could be recovered easily by simple filtration and reused for next run with slightly declining its activity up to six successive runs. The FT-IR spectrum of recycle catalyst after 6th run confirmed that the catalyst was stable during the course of a reaction. The leaching of metal from the PS-Zn-salen is negligible, which was confirmed by AAS and hot filtration test.

Two series of Et 2-[2-anilino-4-(2-thienyl)thiazol-5-yl]acetates I [R = 3-MeC₆H₄, 4-MeOC₆H₄, 4-BrC₆H₄, etc.] and Et 2-[2-(2-benzylidenehydrazino)-4-(2-thienyl)thiazol-5-yl]acetates II [R¹ = 2-HOC₆H₄, 4-ClC₆H₄, 4-Me₂NC₆H₄] were synthesized and screened for their anti-inflammatory, analgesic and antioxidant activities. In-vivo test results showed that the compounds I [R¹ = 4-FC₆H₄, 4-ClC₆H₄, 3-Cl-4-FC₆H₃, 2,4-Cl₂C₆H₃, 4-BrC₆H₄] exhibited good anti-inflammatory and analgesic activities, similar to that of indomethacin and aspirin, resp. Compounds II showed better anti-oxidant activity than compounds I when compared to ascorbic acid. Further, a mol. docking study was performed to predict the possible binding modes on cyclooxygenase-1 (COX-1) and COX-2 for compounds I and II. Good correlation was observed between the anti-inflammatory activity of the compounds I and II and the results of the binding modes in COX-2.

Transformations of anionic Cu^II chlorocomplexes have been studied under conditions of catalytic exchange reactions between carbon tetrachloride and n-alkanes. It was shown that chlorocuprates are just precursors and are easily reduced to the genuine catalysts, i.e., to the resp. Cu^I complexes. Both the composition and the geometric structure of the precursor (CuCl₄^2-) and, probably, the active site (CuCl₃^2-) have been investigated by several techniques (UV-vis spectroscopy, ESR, extended X-ray absorption fine structure (EXAFS), X-ray absorption near-edge structure (XANES), and static magnetic measurements). The dependence of the metathesis velocity on the [Cl^–]/[Cu] ratio was found to exhibit a maximum most likely corresponding to the highest content of trichlorocuprite CuCl₃^2-.

Nadirova, Maryana A. published the artcileCascade of the Hinsberg / IMDAF reactions in the synthesis 2-arylsulfonyl-3a,6-epoxyisoindoles and 4a,7-epoxyisoquinolines in water, Name: 4-Chloro-3-(trifluoromethyl)benzenesulfonyl Chloride, the publication is Tetrahedron (2021), 132032, database is CAplus.

N-Furfuryl allylamines, readily accessible from corresponding furfurals or furfuryl amines, react with a broad range of aryl sulfonyl chlorides with the formation of a 3a,6-epoxyisoindoles I [Ar = Ph, 2-thienyl, Ts, etc.; R¹ = H, I, Et, etc.; R² = H, Br, Me] in one synthetic stage was reported. Usually, in boiling water, the interaction sequence involved two consecutive steps: the Hinsberg reaction and the intramol. Diels-Alder furane (IMDAF) reaction. The scope and limitations of the proposed method were thoroughly investigated, and it was revealed that the key [4+2] cycloaddition step proceeded through an exo-transition state, giving rise to the exclusive formation of a single diastereomer of the target heterocycle. The method allowed the ability to obtain N-sulfaryl-substituted 3a,6-epoxyisoindoles I and 4a,7-epoxyisoquinolines, which were potentially useful substrates for further transformations and subsequent bioscreening, in particular antimicrobial activity.
