The phospholipase A and acyltransferase (PLAAT) family of cysteine hydrolases consists of five members, which are involved in the Ca2+-independent production of N-acylphosphatidylethanolamines (NAPEs). NAPEs are lipid precursors for bioactive N-acylethanolamines (NAEs) that are involved in various physiol. processes such as food intake, pain, inflammation, stress, and anxiety. Recently, we identified α-ketoamides as the first pan-active PLAAT inhibitor scaffold that reduced arachidonic acid levels in PLAAT3-overexpressing U2OS cells and in HepG2 cells. Here, we report the structure-activity relationships of the α-ketoamide series using activity-based protein profiling. This led to the identification of LEI-301(I), a nanomolar potent inhibitor for the PLAAT family members. LEI-301 reduced the NAE levels, including anandamide, in cells overexpressing PLAAT2 or PLAAT5. Collectively, LEI-301 may help to dissect the physiol. role of the PLAATs.

For the first time, using PCl3, a range of tert-Bu esters is chlorinated successfully, allowing access of both aromatic acid chlorides and aliphatic acid chlorides RCOCl (R = Ph, 4-FC6H4, 4-MeC6H4, etc.) in good yields. The method features simple reaction conditions and wide substrate scope. Various tert-Bu esters including aryl esters, alkenyl esters, and alkyl esters were tolerated well in the reaction. A plausible mechanism is proposed.

The synthesis of a series of new sorbicillinoid I [R1 = R2 = R3 = H, 3-methylbut-2-enoyl, (2E,4E)-hexa-2,4-dienoyl, (E)-3-(4-chlorophenyl)prop-2-enoyl, etc.; R2 = R3 = Me] analogs was reported and assessed their anti-inflammatory activities. Results reveal that side chain substitution with (E)-2-butenoyl, (E)-3-(4-fluorophenyl)-2-propenoyl, and (E)-3-(3,4,5-trimethoxyphenyl)-2-propenoyl significantly enhanced the inhibitory effects of the derivatives on nitric oxide (NO) production and inducible NO synthesis (iNOS) expression stimulated by lipopolysaccharides (LPS) in mouse macrophage. Further chem. derivatization showed that the monomethylresorcinol skeleton worked better than the dimethylresorcinol skeleton in inhibiting LPS-induced inflammatory response in cultured cells. Among the synthesized sorbicillinoid analogs, compounds I [R1 = (E)-but-2-enoyl, R2 = R3 = Me; R1 = (E)-3-(3,4,5-trimethoxyphenyl)prop-2-enoyl, R2 = R3 = Me] exhibited the strongest anti-inflammatory activities, holding the promise of being developed into lead compounds that was explored as potent anti-inflammation agents.

Anderson, Marc O.; Sherrill, John; Madrid, Peter B.; Liou, Ally P.; Weisman, Jennifer L.; DeRisi, Joseph L.; Guy, R. Kiplin published the artcile< Parallel synthesis of 9-aminoacridines and their evaluation against chloroquine-resistant Plasmodium falciparum>, SDS of cas: 22717-55-1, the main research area is synthesis antimalarial aminoacridine derivative.

A parallel synthetic strategy to the 9-aminoacridine scaffold of the classical antimalarial drug quinacrine is presented. The method features a new route to 9-chloroacridines that utilizes triflates of salicylic acid derivatives, which are com. available in a variety of substitution patterns. The route allows ready variation of the 2 diversity elements present in this class of mols.: the tricyclic aromatic heterocyclic core, and the disubstituted diamine side-chain. In this study, a library of 175 compounds was designed, although only 93 of the final products had purities acceptable for screening. Impurity was generally due to incomplete removal of 9-acridones, a degradation product of the 9-chloroacridine synthetic intermediates. The library was screened against two strains of P. falciparum, including a model of the drug-resistant parasite, and 6 novel compounds were found to have IC50 values in the low nanomolar range.

The discovery of novel succinate dehydrogenase inhibitors (SDHIs) has attracted great attention worldwide. Herein, a fragment recombination strategy was proposed to design new SDHIs by understanding the ligand-receptor interaction mechanism of SDHIs. Three fragments, pyrazine from pyraziflumid, diphenyl-ether from flubeneteram, and a prolonged amide linker from pydiflumetofen and fluopyram, were identified and recombined to produce a pyrazine-carboxamide-diphenyl-ether scaffold as a new SDHI. After substituent optimization, compound 6y was successfully identified with good inhibitory activity against porcine SDH, which was about 2-fold more potent than pyraziflumid. Furthermore, compound 6y exhibited 95% and 80% inhibitory rates against soybean gray mold and wheat powdery mildew at a dosage of 100 mg/L in vivo assay, resp. The results of the present work showed that the pyrazine-carboxamide-diphenyl-ether scaffold could be used as a new starting point for the discovery of new SDHIs.

The vapor-phase chlorination of phthalic anhydride (I), 4-chlorophthalic anhydride (II), and 3-chlorophthalic acid (III) at 390° to 600° is highly selective. Chlorination of I at 390°-450° gave high yields of monochlorinated products accompanied by only small amounts of dichlorination with a high degree of regioselectivity favoring the formation of II. Chlorination of III by this method has provide the first direct synthesis of 3,5-dichlorophthalic anhydride from I via chlorination.

Prothioconazole is a fungicide that has a wide number of applications in agriculture, and it can ensure the safety of crops, users, and the environment. Prothioconazole, as a suppressor of copper dissolution in 0.5 M H2SO4 solution, has been evaluated using electrochem. experiments, weight loss tests, quantum chem. calculations, and SEM (SEM). The electrochem. test results showed that prothioconazole was an excellent inhibitor, and the anticorrosion ability increased with the inhibitor concentration The interaction of prothioconazole with copper is a spontaneous adsorption process accompanied by typical chemisorption. The number of water mols. (X) displaced by one prothioconazole mol. was obtained using diverse substitutional adsorption models based on electrochem. impedance spectroscopy (EIS) data. In addition, the Fukui functions indicate that the triazole and benzene rings and the -C=S atoms were the main active sites for the adsorption process.
