Experimental and DFT studies on Hexacoordinated acyl(alkyl)and Pentacooordinated Hydroxyalkyl(phosphinite)erhodium(III). Catalytic Hydrolysis of Ammonia Borane

[Rh(nbd)Cl](2) (nbd=norbornadiene) reacts with quinoline-8-carbaldehyde (C9H6NCHO) and pyrazole (Hpz) affording, depending on Rh/Hpz ratio, acyl-alkyl [Rh(mu-Cl)(C9H6NCO)(Hpz)(sigma-C7H9)](2) (1) or [RhCl(C9H6NCO)(Hpz)(2)(sigma-norbornenyl)] (2), stereoselectively as confirmed by DFT calculations. Hydrogen bond between NH-pyrazole and O-acyl occurs. 1 and 2 react with diphenylphosphine oxide (SPO) giving 16e [RhCl(C9H6NC(nbyl))(Ph2PO)(Hpz)] (3) through SPO kappa(1)-P-coordination, C-C bond coupling between acyl and norbornenyl and outer-sphere O(P)-to-O(C) hydrogen transfer. 3 shows distorted trigonal bipyramidal structure with weak intramolecular (C)-OH…O(=P) and NH…Cl hydrogen bonds. DFT calculations indicate this 16e structure being favoured by sigma- and pi-type orbital multi-overlapping between pyrazole and both the OH…O and chlorine and by intermolecular forces in the crystal. Solutions of 3 contain an equilibrium between trigonal bipyramid and a square-planar pyramid with OH interacting with phosphoryl and NH, confirmed by DFT C-13 NMR calculations. 1 is very efficient homogeneous catalyst for H3N-BH3 hydrolysis to release hydrogen under air.

Estrogen Receptor 1 (ESR1) Agonist Induces Ovarian Differentiation and Aberrant Mullerian Duct Development in the Chinese Soft-shelled Turtle, Pelodiscus sinensis

Estrogens play critical roles in ovarian and reproductive organ development, but the molecular signaling pathways in non-mammalian vertebrates are not well understood. Studies of reptiles have indicated that administration of exogenous estrogens during embryonic development causes ovarian differentiation and presumptive male to female sex-reversal. The Chinese soft-shelled turtle, Pelodiscus sinensis, belongs to the family Trionychidae and exhibits genotypic sex determination system with ZZ/ZW sex chromosomes. In order to assess the role of estrogens and their signaling pathway on sex determination and differentiation, P sinensis eggs were given a single administration of endogenous estrogen,1713-estradiol (E2) or a synthetic estrogen receptor 1 (ESR1) agonist, 4,4′,4 ”-(4-propyl-[1H]-pyrazole-1,3,5-triyl) trisphenol (PPT) in ovo during gonadal differentiation, and the subsequent effects were examined during a final developmental stage prior to hatching. The administration of both E2 and PPT induced ovarian differentiation in genetic male embryos. Intriguingly, PPT but not E2 induced the Mullerian duct enlargement and aberrant glandular development. These data suggest that ovarian differentiation and reproductive tract anomalies induced by the exogenous estrogen exposure act through ESR1 in the Chinese soft-shelled turtles.

Iodonium salts as efficient iodine(iii)-based noncovalent organocatalysts for Knorr-type reactions

Hypervalent iodine(iii)-derivatives display higher catalytic activity than other aliphatic and aromatic iodine(i)- or bromine(i)-containing substrates for a Knorr-type reaction of N-acetyl hydrazides with acetyl acetone to give N-acyl pyrazoles. The highest activity was observed for dibenziodolium triflate, for which 10 mol% resulted in the generation of N-acyl pyrazole from acyl hydrazide and acetyl acetone typically at 50 degrees C for 3.5-6 h with up to 99% isolated yields. H-1 NMR titration data and DFT calculations indicate that the catalytic activity of the iodine(iii) is caused by the binding with a ketone.

Soil dissipation of sugarcane billet seed treatment fungicides and insecticide using QuEChERS and HPLC

Chemical treatment of sugarcane seed with fungicides and insecticides prior to planting increases yields of cane and sugar for the perennial, annually harvested crop. However, the fate of the applied chemicals is unknown. Therefore, the purpose of this study was to measure the aerobic dissipation of selected billet seed treatment chemicals in a mineral sugarcane soil from Louisiana. Soil samples from the surface 15 cm were treated with either thiamethoxam, azoxystrobin, fluxapyroxad, propiconazole, or pyraclostrobin and monitored over 100 days under laboratory conditions. Insecticide and fungicide levels were determined by high performance liquid chromatography. Dissipation data were fitted to four kinetic models: simple first-order (SFO), first order multi-compartment (FOMC), double-first order in parallel (DFOP), and hockey-stick (HS). The dissipation half-life (DT50) of thiamethoxam, azoxystrobin, fluxapyroxad, propiconazole, or pyraclostrobin were 275, 100, 144, 74, and 39 d, respectively. Overall, the DT50 for the pesticides in the study indicated medium to long persistence in soil under the conditions of the experiment. This is the first report for several of these pesticides related to the aerobic dissipation in soils used to grow sugarcane.

Mechanism of Action of Novel Pyrazole Carboxamide Containing a Diarylamine Scaffold against Rhizoctonia solani

In the last few decades, Rhizoctonia solani causing rice sheath blight has resulted in a lot of economic losses in the world. Therefore, many novel pyrazole carboxamide fungicides have been intensively researched and employed to fight against it. In this regard, in recent years, our group reported a novel pyrazole carboxamide containing a diarylamine scaffold with good antifungal activity against rice sheath blight in the pot test and field trial. Following this project, the antifungal mechanism of action of the pyrazole carboxamide has been elucidated in this work. The antifungal result showed that compound SCU2028, N-[2-[(3-chlorophenyl)amino]-phenyl]-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide, was equivalent to the commercial fungicide thifluzamide and its EC50 value was 0.022 mg/L against R. solani. Also, the observation results by scanning electron microscopy and transmission electron microscopy showed that it could destroy the fungus’ cell walls or membranes and result in the leakage of contents and increase of the number of mitochondria and abnormal morphology. Meanwhile, the result on the mitochondrial membrane potential (MMP) showed that it could decrease R. solani’s MMP. Furthermore, the results by label-free quantitative proteomic analysis showed that 1153 proteins were found after R. solani was treated with compound SCU2028, including 212 proteins in the control group and 257 proteins in the treatment group. A total of 142 differential proteins were obtained, of which 92 proteins were upregulated and 50 proteins were downregulated. The differentially expressed proteins affected a series of physiological and biochemical pathways in the mitochondria, endoplasmic reticulum, ribosome, and other related GO and KEGG pathways. In particular, the inhibition of the respiratory chain caused by the TCA cycle and oxidative phosphorylation KEGG pathway indicated that complex II (succinate dehydrogenase) and complex IV (cytochrome oxidase) might be compound SCU2028’s main action targets. In addition, multiple experiments of qRT-PCR, enzyme activity detection, and molecular docking confirmed complex II and complex IV as targets. It could be seen that these findings provided a theoretical support for further research and development of the pyrazole carboxamide fungicides.

A New Approach for the Synthesis and Biological Activities of Novel Thiazolyl-Pyrazole Derivatives

According to the encouraging biological activity and low cytotoxicity profile of thiazolyl-pyrazole hybrid, many researchers are making efforts in this research area. 2-(2-(5-Acetyl-4-methylthiazol-2-yl)hydrazono)acenaphthylen-1(2H)-one (3) was synthesized by the reaction of acenaphthenequinone-thiosemicarbazone (1) with 3-chloroacetylacetone (2) and utilized as a precursor for the production of various thiazolyl-pyrazole compounds. The reaction of 3 with DMF-DMA followed by treating the produced enaminone 4 with hydrazines furnished the corresponding thiazolyl-pyrazoles 5 a-c. In addition, 1,3-dipolar cycloaddition of enaminone 4 with alpha-ketohydrazonyl chlorides 6 through a regioselective manner gave thiazolyl-pyrazoles 7 a-c. The reaction of 3 with arylhydrazines yielded the corresponding hydrazones 8 a-c, which were subjected to Vilsmeier formylation reaction and furnished the thiazolyl-pyrazoles 9 a-c. Meanwhile, the synthesized thiazolyl-pyrazoles were screened to discover their antibacterial, antifungal, antioxidant, and antitumor activities. The antibacterial screening revealed that derivatives 7 a-c, 8 a-c, and 9 a-c demonstrated minimal inhibition concentrations toward B. subtilis and S. typhimurium. While derivatives 7 c and 9 c showed respectable antifungal effectiveness against C. albicans. Further, antioxidant effectiveness of the synthesized derivatives 7 a-c and 9 a-c revealed antioxidant activity superior to derivative 8 a-c and 5 a-c compared to ascorbic acid. Likewise, thiazolyl-pyrazole derivatives 5 a-c displayed higher cytotoxic efficacy than their corresponding derivatives 9 a-c, 8 a-c and 7 a-c, respectively.
