Discovery, synthesis and biological characterization of a series of: N -(1-(1,1-dioxidotetrahydrothiophen-3-yl)-3-methyl-1 H -pyrazol-5-yl)acetamide ethers as novel GIRK1/2 potassium channel activators

The present study describes the discovery and characterization of a series of N-(1-(1,1-dioxidotetrahydrothiophen-3-yl)-3-methyl-1H-pyrazol-5-yl)acetamide ethers as G protein-gated inwardly-rectifying potassium (GIRK) channel activators. From our previous lead optimization efforts, we have identified a new ether-based scaffold and paired this with a novel sulfone-based head group to identify a potent and selective GIRK1/2 activator. In addition, we evaluated the compounds in tier 1 DMPK assays and have identified compounds that display nanomolar potency as GIRK1/2 activators with improved metabolic stability over the prototypical urea-based compounds.

Design and Synthesis of Novel 4-Hydroxyl-3-(2-phenoxyacetyl)-pyran-2-one Derivatives for Use as Herbicides and Evaluation of Their Mode of Action

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.

An Efficient One-Pot Synthesis of 2-(Aryloxyacetyl)cyclohexane-1,3-diones as Herbicidal 4-Hydroxyphenylpyruvate Dioxygenase Inhibitors

4-Hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) is an important target for new bleaching herbicides discovery. As a continuous work to discover novel crop selective HPPD inhibitor, a series of 2-(aryloxyacetyl)cyclohexane-1,3-diones were rationally designed and synthesized by an efficient one-pot procedure using N,N′-carbonyldiimidazole (CDI), triethylamine, and acetone cyanohydrin in CH2Cl2. A total of 58 triketone compounds were synthesized in good to excellent yields. Some of the triketones displayed potent in vitro Arabidopsis thaliana HPPD (AtHPPD) inhibitory activity. 2-(2-((1-Bromonaphthalen-2-yl)oxy)acetyl)-3-hydroxycyclohex-2-en-1-one, II-13, displayed high, broad-spectrum, and postemergent herbicidal activity at the dosage of 37.5-150 g ai/ha, nearly as potent as mesotrione against some weeds. Furthermore, II-13 showed good crop safety against maize and canola at the rate of 150 g ai/ha, indicating that II-13 might have potential as a herbicide for weed control in maize and canola fields. II-13 is the first HPPD inhibitor showing good crop safety toward canola.

Synthesis and Biological Activity of Ethyl 4-Alkyl-2-(2-(substituted phenoxy)acetamido)thiazole-5-carboxylate

(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.

Synthesis and biological activity of 1-(Substituted phenoxyacetoxy)- 1-(pyridin-2-yl or thien-2-yl)methylphosphonates

A series of novel O,O-dimethyl 1-(substituted phenoxyacetoxy)-1-(pyridin-2-yl or thien-2-yl)methylphosphonates 6a-n and 7a-d were synthesized. Their structures were confirmed by IR, 1H NMR, mass spectroscopy, and elemental analyses. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal and fungicidal activities. For example, the title compounds 6a, 6c, 6l, 6m, and 7d possess 90-100% inhibition against most of the tested plants at the dosage of 1500 g ai/ha, whereas the title compounds 6b, 6g-h and 6n possess 92-100% inhibition against Fusarium oxysporum, Phyricularia grisea, Botrytis cinereapers, Gibberella zeae, Sclerotinia sclerotiorum, and Cercospora beticola at the concentration of 50mg/L.

Design, synthesis and molecular docking of amide and urea derivatives as Escherichia coli PDHc-E1 inhibitors

By targeting the ThDP binding site of Escherichia coli PDHc-E1, two new 'open-chain' classes of E. coli PDHc-E1 inhibitors, amide and urea derivatives, were designed, synthesized, and evaluated. The amide derivatives of compound 6d, with 4-NO2 in the benzene ring, showed the most potent inhibition of E. coli PDHc-E1. The urea derivatives displayed more potent inhibitory activity than the corresponding amide derivatives with the same substituent. Molecular docking studies confirmed that the urea derivatives have more potency due to the two hydrogen bonds formed by two NH of urea with Glu522. The docking results also indicate it might help us to design more efficient PDHc-E1 inhibitors that could interact with Glu522.

Synthesis and herbicidal activity of 2-(substituted phenoxyacetoxy)alkyl-5, 5-dimethyl-1,3,2-dioxaphosphinan-2-one containing fluorine

A series of novel 2-(substituted phenoxyacetoxy)alkyl-5,5-dimethyl-1,3,2- dioxaphosphinan-2-one bearing fluorine 5a-n and fluorine free 5o-q were designed and synthesized. The results of bioassay showed that some of the target compounds exhibited excellent herbicidal activities to Abutilon theophrasti, Brassica juncea, Amaranthus retroflexus and Eclipta prostrata in post-emergence treatment at a dosage of 150 g ai/ha. It could be found that the type and position of fluorine-containing group as X or Y on benzene ring had a very important effect on herbicidal activity. Compound 5l 2-[(2-chloro-4- fluorophenoxy)acetoxy](methyl)methyl-5,5-dimethyl-1,3,2-dioxaphosphinan-2-one showed notable herbicidal activity, with 100% inhibition against A. theophrasti and A. retroflexus; and compound 5m 2-(3-trifluoromethylphenoxyacetoxy)(methyl) methyl-5,5-dimethyl-1,3,2-dioxaphosphinan-2-one with 100% inhibition against A. theophrasti even at a dosage of 75 g ai/ha. Additional crop selectivity testing showed that compounds 5g 2-(3-trifluoromethylphenoxyacetoxy)(phenyl)methyl-5,5- dimethyl-1,3,2-dioxaphosphinan-2-one and 5l are safe to rice, corn, cotton, rape and wheat.
