Human African trypanosomiasis (HAT), caused by the parasitic protozoa Trypanosoma brucei, is one of the fatal diseases in tropical areas and current medicines are insufficient. Thus, development of new drugs for HAT is urgently needed. Leucyl-tRNA synthetase (LeuRS), a recently clinically validated antimicrobial target, is an attractive target for development of antitrypanosomal drugs. In this work, we report a series of α-phenoxy-N-sulfonylphenyl acetamides as T. brucei LeuRS inhibitors. The most potent compound 28g showed an IC50 of 0.70 μM which was 250-fold more potent than the starting hit compound 1. The structure-activity relationship was also discussed. These acetamides provided a new scaffold and lead compounds for the further development of clinically useful antitrypanosomal agents.

In order to develop a novel herbicide containing the β-triketone motif, a series of 4-hydroxyl-3-(2-phenoxyacetyl)-pyran-2-one derivatives were designed and synthesized. The bioassay results showed that compound II15 had good pre-emergent herbicidal activity even at a dosage of 187.5 g ha-1. Moreover, compound II15 showed a broader spectrum of weed control when compared with a commercial herbicide 2,4-dichlorophenoxyacetic acid (2,4-D), and displayed good crop safety to Triticum aestivum L. and Zea mays Linn. when applied at 375 g ha-1 under pre-emergence conditions, which indicated its great potential as a herbicide. More importantly, studying the molecular mode of action of compound II15 revealed that the novel triketone structure is a proherbicide of its corresponding phenoxyacetic acid auxin herbicide, which has a herbicidal mechanism similar to that of 2,4-D. The present work indicates that the 4-hydroxyl-3-(2-phenoxyacetyl)-pyran-2-one motif may be a potential lead structure for further development of novel auxin-type herbicides.

The paper presents the activity trends for a novel series of phenoxyacetyl amides as human TRPM8 receptor agonists. This series encompasses in vitro activity values ranging from the micromolar to the picomolar levels. Sensory evaluation of these molecules highlights their relevance as cooling agents for oral applications. The positive outcome of the complete evaluation of N-(1H-pyrazol-3-yl)-N-(thiophen-2-ylmethyl)-2-(p-tolyloxy)acetamide resulted in its approval for Generally Recognized As Safe (GRAS) status by the Flavor & Extract Manufacturer Association (FEMA) as FEMA 4809.

Based on the structure of the previously identified leads, new series of compounds containing 1,2,4-oxadiazole core was designed. A small, diverse library of 51 compounds including both 2-(acylamino)ethyl and 2-ureidoethyl side chains was synthesized using parallel chemistry and tested for antiproliferative activity against prostate cancer DU-145 cell line. Four hit compounds - all belonging to 2-ureidoethyl series - were identified and three compounds were confirmed as 10-20 μM inhibitors. The similarity in compounds' periphery and the data obtained previously suggest a similar mode of action for these compounds which was postulated as tubulin inhibition and was confirmed by in silico docking. These data provide further evidence for the privileged character of 1,2,4-oxadiazoles in antiproliferative compound design.

(Chemical Equation Presented) A series of novel ethyl 4-(methyl or trifluoromethyl)-2-(2-(substituted phenoxy)acetamido)thiazole-5-carboxylates 7a, 7b, 7c, 7d, 7e and 8f, 8g, 8h, 8i, 8j, 8k, 8l, 8m, 8n, 8o, 8p, 8q, 8r were synthesized, and their structures were confirmed by IR, 1H-NMR, MS spectra and elemental analysis. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal activities. Compared with the fluorine free compounds 7a, 7b, and 7e, the compounds bearing fluorine 8g, 8j, and 8q showed higher herbicidal activities with 70-100% inhibition against Capsella bursa-pastoris, Amaranthus restroflexus, and Eclipta prostrata at the dosage of 150 g/ha, which indicated that the trifluoromethyl on the thiazole ring was beneficial for the herbicidal activity. Furthermore, compounds 8f, 8g, 8h, 8i, 8j, 8k, 8l, 8m, 8n, 8o, 8p, 8q, 8r were tested for fungicidal activity against Pseudoperonospora cubensis at 500 μg/mL. Compounds 8f and 8q showed the best fungicidal activity with more than 80% inhibition.

A series of new aryloxyacetamide derivatives 10a-s and 14a-m are designed and synthesized. Their protective activities against the glutamate-induced cell death were investigated in differentiated rat pheochromocytoma cells (PC12 cells). Most compounds exhibited neuroprotective effects, especially for 10m, 10r, 14b and 14c, which showed potential protection of PC12 cells at three doses (0.1, 1.0, 10 μM). MTT assay, Hoechst 33342/PI double staining, and high content screening (HCS) revealed that pretreatment of the cells with 10m, 10r, 14b and 14c has significantly decreased the extent of cell apoptosis in a dose-dependent manner. The results of western blot analysis demonstrated these compounds suppressed apoptosis of glutamate-induced PC12 cells via caspase-3 pathway. These compounds can be lead compounds for further discovery of neuroprotective agents for treating cerebral ischemic stroke. Basic structure-activity relationships are also presented.

A new method was developed for the photoinduced dearomatization of arenes through an intramolecular cycloaddition with aza-o-xylylenes generated by excited-state intramolecular proton transfer (ESIPT) in the readily available photoprecursors. The [2+4] topology of this cycloaddition is unprecedented for photo-dearomatizations of benzenoid aromatic carbocycles. It provides rapid access to novel heterocycles, cyclohexadieno-oxazolidino-quinolinols, as valuable synthons for a broad range of post-photochemical transformations. I'm so excited: Photoinduced dearomatization of arenes was achieved through intramolecular cycloaddition with aza-o-xylylenes generated by excited-state intramolecular proton transfer in the readily available photoprecursors. The [2+4] topology of this cycloaddition is unprecedented for photo-dearomatizations of benzenoid aromatic carbocycles and produces the novel heterocycles cyclohexadieno-oxazolidino-quinolinols.
