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.

Photophysical properties of the ReI and RuII complexes of a new C60-substituted bipyridine ligand

The rhenium(I) and ruthenium(II) complexes of a fullerene-substituted bipyridine ligand have been prepared. Electrochemical studies indicate that some ground state electronic interaction between the fullerene subunit and the metal-complexed moiety are present in the ReI but not the RuII complex. The photophysical properties have been investigated by steady-state and time-resolved UV/Vis-NIR luminescence spectroscopy and nanosecond laser flash photolysis in CH2Cl2 solution, and compared to those of the corresponding model compounds. Excitation of the methanofullerene moiety in the dyads does not lead to excited state intercomponent interactions. Instead, excitation of the metal-complexed unit shows that the lowest triplet metal-to-ligand-charge-transfer excited state (3MLCT) centered on the ReI- or RuIItype unit is quenched with a rate constant of about 2.5 ¡Á 108 s-1. The quenching is attributed to an electron-transfer (E1T) process leading to the reduction of the carbon sphere, as determined by luminescence spectroscopy for the RuII dyad. Experimental detection of electron transfer in the ReI dyad is prevented due to the unfavorable absorption of the metal-complexed moiety relative to the fullerene unit. However, it can be postulated on the basis of energetic/kinetic arguments and by comparison with the RuII-type array. The primary E1T process is followed by charge-recombination to give the lowest-lying fullerene triplet excited state (3C60) with quantitative yield, as determined by sensitized singlet oxygen luminescence experiments. Direct 3MLCT ? 3C60 triplet-triplet energy-transfer (EnT) does not successfully compete with E1T since it is highly exoergonic and located in the Marcus inverted region. The quantum yield of singlet oxygen sensitization (phiDelta) of the RuI-based dyad is found to be lower (0.80) than for the corresponding RuII derivative (1.0). This is likely to be the consequence of different conformational structures for the two dyads, rather than a different yield of 3C60 formation.

Access to well-defined heterogeneous catalytic systems via ring-opening metathesis polymerization (ROMP): Applications in palladium(II)-mediated coupling reactions

The preparation of a new heterogeneous palladium(II)-based catalyst and its homogeneous analogue and their use for Heck-type, alkyne and amine couplings are described. The heterogeneous catalytic system is based on a polymer-bound dichloropalladium di(pyrid-2-yl)amide and was prepared via ring-opening metathesis copolymerization of norborn-2-ene-5-(N,N-di(pyrid-2-yl))carbamide with 1,4,4a,5,8,8a-hexahydro-1,4,5,8-exoendo-dimethanonaphthalene and subsequent loading of the resulting resin with palladium(II) chloride. The heterogeneous catalyst is air, moisture, and temperature stable up to 150 C and highly active (94-99% yields) in the vinylation of aryl iodides and aryl bromides (Heck-type couplings) with turn-over numbers (TONs) of up to 210000. Even higher TON’s (up to 350000) may be achieved in the arylation of alkynes. High yields (?95%) and TONs (?24000) may additionally be achieved in the tetrabutylammonium bromide (TBAB) assisted vinylation of aryl chlorides. Moderate yields (<65%) and TONs (<4000) are observed in the amination of aryl bromides. A soluble analogue of the heterogeneous system, N,N-di(pyrid-2-yl)acetamide palladium dichloride (2), was prepared from palladium(II) chloride and N,N-di(pyrid-2-yl)acetamide (1) and characterized by X-ray analysis. 2 crystallizes in the monoclinic space group P21/n, a = 835.0(1) pm, b = 1494.3(4) pm, c = 1199.3(2) pm, alpha = 90, beta = 109.05(2), gamma = 90, Z = 4. It served as a model compound for the elucidation of the actual geometry of the catalytic species. The unstrained geometry of 2 with almost ideal angles and bond lengths explaines the high stability of the catalytic center. The significantly higher catalytic activity of the heterogeneous system compared to the homogeneous one suggests well-defined ligand-bound catalytic sites rather than polymer-supported palladium colloids.

Synthesis and deuterium labelling of the pure selective estrogen receptor modulator (SERM) acolbifene glucuronides

Acolbifene (EM-652¡¤HCl, SCH 57068¡¤HCl), a highly potent and orally active selective estrogen receptor modulator (SERM), is at late stage clinical development for the treatment of estrogen-sensitive breast cancer. Acolbifene-7-glucuronide 1 (major) and acolbifene-4?-glucuronide 2 (minor) were identified as metabolites of acolbifene in the human. The two monoglucuronides and a diglucuronide 3 as well as the corresponding 2H-labelled derivatives 4-6 were synthesised for use as preclinical and clinical standards for LC-MS/MS analysis. All glucuronides were prepared by the Schmidt glycosylation of monoprotected acolbifene with a glucuronyl imidate at – 10C to prevent epimerisation at the C-2 position. The two monoglucuronides 1 and 2 of acolbifene were separated by semi-preparative HPLC. Incorporation of three deuteriums was achieved by alkylation of chromanone 15 with C2H3MgI followed by dehydration with C 2H3CO2 2H/2H 2O. After chemical resolution and salt neutralisation, [ 2H3]acolbifene 19 was obtained with 99.4% enantiomeric purity and >98% isotopic purity. Copyright

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).
