The aim of this study was to determine how various derivatives of isoxazole affect photosynthetic apparatus of different tomato species grown in a greenhouse and under field conditions. Measurements of chlorophyll fluorescence of photosystem II (PSII) were used as an indicator of the stress induced by isoxazoles on photosynthetic energy conversion. Chlorophyll fluorescence yield provides quantitative information not only on steady-state photosynthesis, but also on various mechanisms of protection against stress-induced damage and the extent to which performance of photosynthesis is limited by photochemical and non-photochemical processes. Measurements were made on tomato plants in various stages of growth (from the 3rd to 15th leaf), in different seasons of the year. The data show that the age of plants does not have a significant influence on Fv/Fm values and it seems that younger plants are more sensitive to the used isoxazole derivatives. Selected isoxazoles did not affect the plant photosynthesis. Practical applications: The isoxazole derivatives show inhibitory activity against growth of the fungus pathogens. The objective of this work was to test the ability of the chlorophyll fluorescence measurements as an indicator of the changes induced by isoxazole compounds on photosynthetic energy conversion of tomato plants. Regarding importance of tomato as a very popular and widely consumed all over the world vegetable, the effect of different isoxazole derivatives with different fungicidal activity on tomato plant was examined. The use of some of the tested isoxazolines due to their lack of toxicity for the plants is very promising.

Background: In the field of coordination chemistry, the introduction of heterocyclic substituents into the structure of beta-diketone enables ligand to produce multiple coordination sites. The adoption of small steric oxime group into the structure of heterocyclic beta-diketone by Schiff-base condensation will further increase coordination sites and facilitate the generation of polynuclear structures. Objective: A series of beta-diketones (2a-2c) containing different heterocycles such as pyridine, thiophene and furan and their corresponding isoxazole compounds (3a-3c) were synthesized. Materials and Methods: The Claisen condensations were investigated in a solvent-free rheological phase system at room temperature to obtain heterocyclic beta-diketones 2a-2c, which further reacted with hydroxylamine hydrochloride to obtain heterocyclic isoxazoles 3a-3c. All these compounds were well characterized by EA, IR,1H NMR and X-ray crystal diffraction to confirm the structures. Synthetic mechanisms of compounds and the effects of different heterocycles on reactivity were discussed deeply. Results:1H NMR indicated that these beta-diketones do not exist as a total diketonic form but an equilibration between diketone and enol forms in CDCl3 solvent, in which the enol form accounts for 98.0% in 2a, 94.3% in 2b, 95.5% in 2c. While the crystal structures of 2a-2c showed that the reaction allows to isolate diketones in solid state. Crystal structures of 3a-3c showed that the neutral beta-ketone oximes resonate and cyclize to form the target heterocyclic isoxazoles. Conclusion: SN1 nucleophilic substitution mechanism of Claisen ketoester condensation was proposed for the syntheses of 2a-2c, and SN1 single molecule nucleophilic substitution reaction mechanism was put forward for 3a-3c.

The isoxazole derivatives gained significant attention in our daily life from better biological activity to the semiconducting materials. This study deals in depth investigation of two isoxazole derivatives, i.e. 2-[(E)-(3,4-Dimethylisoxazol-5-yl)iminomethyl]phenol (1) and 1-[(E)-(3,4-Dimethylisoxazol-5-yl)iminomethyl]-2-naphthol (2) with respect to the geometric, charge transport, optoelectronic and nonlinear optical properties by density functional theory (DFT) and time-dependent DFT. The comprehensible intra-molecular charge transfer (ICT) was conceived from HOMOs to LUMOs. Strength of the electron donor groups was investigated on the absorption wavelengths, emission wavelengths, ionization potentials (IPs), electron affinities (EAs), total/partial densities of states and structure-property relationship. The smaller hole reorganization energies and superior transfer integrals of isoxazole derivatives (1 and 2) than the electron ones are leading to higher hole intrinsic mobility values as compared to the electron mobility exhibit that these systems would be good hole transport contenders. The first hyperpolarizability values are about 19 and 21 times larger than that of urea suggesting that 1 and 2 can also be considered as potential contestants for NLO applications as well.

Conjugated carbonyl compounds have become the most promising type of organic electrode materials for rechargeable Li-ion batteries because only they can achieve simultaneously high energy density, high cycling stability, and high power density. In this work, we have performed first-principles density functional theory (DFT) calculations to explore the fundamental rules of how the electronic structure and redox properties of a typical conjugated carbonyl compound, phenanthrenequinone (PQ), are modified by adjusting the heteroaromatic building blocks. Such a molecular design strategy allows for the improvement in discharge potential while the specific capacity remains nearly unchanged. The correlation between the electronic structures and redox properties for the designed PQ derivatives is systematically discussed. It is demonstrated that the discharge potential of the PQ derivatives depends strongly on the frontier orbital levels, the electric potential, and the Li-bonding configurations. The electrostatic potential (ESP) maps show visible displays of molecular electric structures and can be applied to understand how the redox properties of the PQ derivatives are modified by the heteroaromatic building blocks.

Cyclization of cyclopentanone, formaldehyde and ammonia in vapor phase gives 1,2,3,5,6,7-hexahydrodicyclopenta[b,e]pyridine (HHDCP) and spiro[cyclopentane-1,8?-(1?,2?,3?,5?,6?,7?,8?,8?a) octahydrodicyclopenta[b,e]]pyridine (SCOHDCP) over zeolites HY, HZSM-5, Hbeta and mesoporous Al-MCM-41 molecular sieves. The preliminary screening of catalysts clearly shows that Al-MCM-41 is more suitable for the vapor phase synthesis of HHDCP. As the NH3-TPD profiles of Al-MCM-41 show wide range distribution of acid sites in the temperature range of 200-600 C (weak-medium-strong), Al-MCM-41 is further modified with transition metal ions like V(V), Mn(II), Fe(III), Co(III), Cu(II), La(III) and Ce(III) to fine tune the acid sites. Correlation of activity and selectivity of transition metal modified Al-MCM-41 with the NH3-TPD profiles show that though the conversions are high, selectivity of either HHDCP or SCOHDCP is a preference of acid site strength formed on metal ion modification. Interestingly Co2+ ion modification of Al-MCM-41 resulted distinctly into two sets of acid sites with Tmax around 218 C (weak-medium) and 673 C (strong). The reaction is studied on Co-Al-MCM-41 by adsorbing pyridine at 300 C. The typical acidity available on pyridine adsorbed Co-Al-MCM-41 around 300 C is showing cyclization activity forming only HHDCP indicating that weak-medium acid sites are responsible for the formation of HHDCP. Based on the product distribution plausible reaction mechanism is proposed.

Ebola virus has caused 26 outbreaks in 10 different countries since its identification in 1976, making it one of the deadliest emerging viral pathogens. The most recent outbreak in West Africa from 2014-16 was the deadliest yet and culminated in 11,310 deaths out of 28,616 confirmed cases. Currently, there are no FDA-approved therapeutics or vaccines to treat Ebola virus infections. The slow development of effective vaccines combined with the severity of past outbreaks emphasizes the need to accelerate research into understanding the virus lifecycle and the development of therapeutics for post exposure treatment. Here we present a summary of the major findings on the Ebola virus replication cycle and the therapeutic approaches explored to treat this devastating disease. The major focus of this review is on small molecule inhibitors.
