Improving the fatigue resistance of diarylethene switches

When applying photochromic switches as functional units in light-responsive materials or devices, an often disregarded yet crucial property is their resistance to fatigue during photoisomerization. In the large family of diarylethene photoswitches, formation of an annulated isomer as a byproduct of the photochromic reaction turns out to prevent the desired high reversibility for many different derivatives. To overcome this general problem, we have synthesized and thoroughly investigated the fatigue behavior of a series of diarylethenes, varying the nature of the hetaryl moieties, the bridging units, and the substituents. By analysis of photokinetic data, a quantification of the tendency for byproduct formation in terms of quantum yields could be achieved, and a strong dependency on the electronic properties of the substituents was observed. In particular, substitution with 3,5-bis(trifluoromethyl)phenyl or 3,5-bis(pentafluorosulfanyl)phenyl groups strongly suppresses the byproduct formation and opens up a general strategy to construct highly fatigue-resistant diarylethene photochromic systems with a large structural flexibility.

Photoisomerization of Cyanines. A Comparative Study of Oxygen- and Sulfur-Containing Species

We have compared the photoisomerization properties of two cyanine analogs, 3,3′-diethyloxadicarbocyanine iodide (DODCI) and 3,3′-diethylthiadicarbocyanine iodide (DTDCI).These two molecules are structurally similar, differing oly in the presence of oxygen or sulfur at two heteroatom sites.Measurement of the radiative an nonradiative population relaxation kinetics of these molecules reveals a difference in their equilibrium geometries despite their outward similarities.We relate this difference to the steric constraints imposed by the oxygen and sulfur heteroatoms and to the occurrence of an excited state barrier predicted by semiempirical calculations of the ground- and excited-state isomerization surfaces for these molecules.

Triphenylphosphine-free approach for one-pot N-alkylation of purine, pyrimidine, and azole derivatives with alcohols using P2O5/KI: A facile and selective route to access carboacyclic nucleosides

A facile, selective, and mild synthetic approach for one-pot N-alkylation of nucleobases and other related N-heterocycles via alcohols, using a mixture of P2O5 and KI is described. The reaction of structurally diverse purines, pyrimidines, and/or azoles with primary alcohols with the use of P2O5/KI and basic mixture of Et3N/K2CO3 in refluxing DMF affords the corresponding N-alkyl derivatives (carboacyclic nucleosides) in good to reasonable yields. The influence of different parameters comprising solvent, base, temperature, and substrate/reagent ratios was assessed on the reaction progress. The secondary and tertiary alcohols were failed to react with nucleobases. The main advantageous of current protocol is formation of water soluble side products in which provides simple work-up and purification processes.

A series of 24 analogs of the experimental antischistosomal agent, 5 amino 3 [2 (5 nitro 2 furyl) vinyl] 1,2,4 oxadiazole, was prepared and evaluated in mice infected with Schistosoma mansoni. Although antischistosomal activity was widespread in the series, only four of the compounds showed significant curative properties. Compounds containing 2 imidazolyl and 2 pyridyl groups gave cure rates around 25% at 400 and 250 mg/kg dose levels, respectively. The 2 thiazolyl and 2 pyrimidyl derivatives were especially notable, yielding 100% cures at 250 and 200 mg/kg dose levels, respectively.

Optimization of Novel 1-Methyl-1 H-Pyrazole-5-carboxamides Leads to High Potency Larval Development Inhibitors of the Barber’s Pole Worm

A phenotypic screen of a diverse library of small molecules for inhibition of the development of larvae of the parasitic nematode Haemonchus contortus led to the identification of a 1-methyl-1H-pyrazole-5-carboxamide derivative with an IC50 of 0.29 muM. Medicinal chemistry optimization targeted modifications on the left-hand side (LHS), middle section, and right-hand side (RHS) of the scaffold in order to elucidate the structure-activity relationship (SAR). Strong SAR allowed for the iterative and directed assembly of a focus set of 64 analogues, from which compound 60 was identified as the most potent compound, inhibiting the development of the fourth larval (L4) stage with an IC50 of 0.01 muM. In contrast, only 18% inhibition of the mammary epithelial cell line MCF10A viability was observed, even at concentrations as high as 50 muM.

Characteristic volatile components of trifoliate orange peel (poncirus trifoliata)

The volatile components of the peel of trifoliate orange {Poncirus trifoliata (L.) Raf.}, family Rutaceae, were investigated using SAFE technique after solvent extraction. Limonene was the most abundant component in the peel aroma extract, followed by myrcene, trans-ocimene, indole, caryophyllene, (3E,6E)-farnesene, germacrene D, and phellandrene. In this study, the single sulfur-and nitrogen-containing compound, 4-methyl-5-vinylthiazole, and two macrocyclic lactones, cyclododecanolide and (7Z,10Z,13Z)-hexadecatrien-16-olide, were identified as citrus aroma components for the first time. As a result of AEDA for the polar fraction of the aroma extract, indole, ethyl octanoate and those macrocyclic lactones with musky notes were found to be responsible for the characteristic aroma profile of the peel of trifoliate orange. The enantiomeric distributions of the four odor-active components, linalool, citronellol, ethyl 2-methylbutanoate, and 2-methylbutanoic acid, were also determined by means of multidimensional chiral GC/MS.
