Fabrication and Characterization of Lignin Particles and Their Ultraviolet Protection Ability in PVA Composite Film

Recently, lignin utilization in advanced applications has gained much interest. Due to the limitation of the current use of standard lignin, lignin particles have recently gained attention in overcoming the challenge. In this work, the spherical lignin particles obtained from organosolv lignin (OL) were prepared using the dialysis method with tetrahydrofuran (THF) or ethanol as the solvent. From the result, it was found that the types of lignin and solvent, initial lignin concentration, and stirring rate strongly affected the size of fabricated particles. Moreover, the preparation of lignin particles using THF as a solvent showed more uniform and symmetric spherical lignin particles. The stability of the particle dispersion was examined under various pH conditions. Moreover, lignin samples were also introduced into the poly(vinyl alcohol) (PVA) for the production of ultraviolet (UV)-blocking composite film. Mechanical and optical properties of composite film were also observed. As a result, the prepared lignin-PVA composite film showed great ultraviolet (UV) protective potential in both UVA and UVB regions.

Conformations of saturated five-membered heterocycles evaluated by MP2 calculations

The conformation of saturated heterocyclic rings is often a subject of computational investigations. In spite of their simple molecular structure, study of their conformation is often hindered by the high sensitivity for the type of the accepted potential of interactions and limitations inherent to introducing artificial constraints. Here we report the results of the MP2 calculations carried out within the aug-cc-pVTZ basis set and aimed to elucidate the basic conformational properties of a series of prototypic heterocyclic compounds, containing saturated five-membered rings. We have considered: oxolane, thiolane, pyrrolidine, 1,3-dioxolane, 1,2-oxathiolane, 1,3-oxathiolane pyrazolidine, imidazolidine, and cyclopentane (the latter included for comparative purposes). We have identified the local and global minima on the potential energy surface along the pseudorotation path. Moreover, the relative energies of structural and geometrical isomers were estimated. The results reveal a large degree of conformational heterogeneity of the studied compounds which always exhibit more than one type of conformation corresponding to the minimum of the energy. The information about the topology of the given compound is insufficient to predict its conformational properties, including the type of favorable ring shape. However, the magnitude of the out-of-plane deviations exhibit similar range of values for most of the studied compounds. The calculated puckering parameters will provide the essential data for the next stage of related studies exploiting the machine learning methodology.

Modulation on C- and N-terminal moieties of a series of potent and selective linear tachykinin NK2 receptor antagonists

Herein we describe the synthesis of a series of new potent tachykinin NK2 receptor antagonists by the modulation of the Cand N-terminal moieties of ibodutant (MEN 15596, 1). The Nterminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C-terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity for the human NK2 receptor and high in vitro antagonist potency, indicating that a wide range of substituents at both termini can be incorporated in the molecule without detrimental effects on the interactions with the NK2 receptor. Selected compounds were tested in vivo confirming their activity as NK2 antagonists. In particular, after both iv and id administration to guinea pig, compound 61b was able to antagonize NK2-induced colonic contractions with a potency and duration-of-action fully comparable to the reference compound 1 (MEN 15596, ibodutant).

Effect of spray drying on bioactive and volatile compounds in soursop (Annona muricata) fruit pulp

Soursop is seasonal and highly perishable fruit, which limits its commercialization. Thus it is necessary to conserve its pulp so that it is available throughout the year. One of the most common forms of fruit preservation is by dehydration. This work had an objective to dehydrate soursop pulp by spray drying at optimum conditions and to analyze the retention of bioactive and volatile compounds in soursop powder, besides analyzing its antioxidant capacity. The total phenolics, carotenoids and flavonoids contents were determined, while volatile compounds were analyzed by Stir Bar Sorptive Extraction (SBSE) coupled with GC?MS system. The total content of the phenolic compounds and flavonoids in the fresh pulp were 160.28 mg of GAE/100 g and 87.17 mg of quercetin/100 g, respectively while for rehydrated dried powder their values were 158.95 mg of GAE/100 g and 85.17 mg of quercetin/100 g, respectively. The total phenolic compounds, flavonoids and antioxidant capacity did not show any significant difference (p <.05) between the fresh fruit pulp and dehydrated powder. A total of 85 volatile compounds were identified, of which 33 were esters, representing the major class of organic compounds, 15 were terpenes, 10 aldehydes, 7 acids, 5 alcohols, 5 lactones, 3 ketones, and 6 other compounds. Of the total 85 compounds, identified in soursop pulp, 58 compounds were identified in the rehydrated dried powder. The principal compounds for both samples were methyl (E)-2-hexenoate, methyl hexanoate and methyl (E)-2-butanoate, which contribute to soursop aroma according to their Odor Active Values (OAV). Considering that there was no significant difference (p <.05) between fresh pulp and the rehydrated dried powder in concentrations of bioactive compounds and even with the reduction in the concentration of the main volatile compounds while the OAVs of these compounds were relatively high, it is concluded that spray dried powder of soursop pulp retains its nutritional and aroma quality, besides maintaining the antioxidant capacity.

Novel spiroketal pyrrolidine GSK2336805 potently inhibits key hepatitis C virus genotype 1b mutants: From lead to clinical compound

Rapid clinical progress of hepatitis C virus (HCV) replication inhibitors, including these selecting for resistance in the NS5A region (NS5A inhibitors), promises to revolutionize HCV treatment. Herein, we describe our explorations of diverse spiropyrrolidine motifs in novel NS5A inhibitors and a proposed interaction model. We discovered that the 1,4-dioxa-7-azaspiro[4.4]nonane motif in inhibitor 41H (GSK2236805) supported high potency against genotypes 1a and 1b as well as in genotype 1b L31V and Y93H mutants. Consistent with this, 41H potently suppressed HCV RNA in the 20-day RNA reduction assay. Pharmacokinetic and safety data supported further progression of 41H to the clinic.
