Recently, He et al. reported that CCKB receptors located in the neocortex of the brain when bound to their bound natural ligand, CCK peptides, enhance memory, bringing up the possibility that agonists targeting the CCKB receptor may act as therapeutic agents in diseases in which memory loss is marked as observed in dementia and Alzheimer’s. In this report, we describe the synthesis of novel low-molecular weight benzoamine CCKB receptor agonists. The compounds made in this series were determined to be mostly partial agonists, although some antagonists were identified, as well, capable of triggering calcium release in a cell line that overexpresses the CCKB receptor. Compound 35 demonstrated an EC50 of 0.15 mu M in the cell-based assay, but more importantly, several of the compounds, including 35, demonstrated a physiological effect, inducing long-term potentiation in rat brains comparable to the CCK-8 peptide albeit at much higher concentrations. Based on these findings, benzoamines may be the basis for a new series of CCKB receptor agonists in drug-discovery efforts that seek to develop therapeutics to prevent memory loss.

Background: The association of sugar containing beverages (SCBs) with risk of breast, endometrial, ovarian and colorectal cancers is unclear. Therefore, we investigated these associations in the Canadian Study of Diet, Lifestyle, and Health. Methods: The study population comprised an age-stratified subcohort of 3185 women and 848, 161, 91 and 243 breast, endometrial, ovarian and colorectal cancer cases, respectively. We used Cox proportional hazards regression models modified for the case-cohort design to assess the associations of SCBs with risk of the aforementioned cancers. Results: Compared to SCB intake in the lowest tertile, SCB intake in the highest tertile was positively associated with endometrial cancer risk (HRT3 vs T1 = 1.58, 95 % CI = 1.08-2.33 and 1.78, 95 % CI = 1.12-2.81 for overall and Type 1 endometrial cancer, respectively) and ovarian cancer (HRT3 vs T1 = 1.76, 95 % CI: 1.09-2.83). Fruit juice intake was also positively associated with risk of Type 1endometrial (HRT3 vs T1 = 1.63, 95 % CI = 1.03-2.60). After excluding women with diabetes or cardiovascular diseases, we also observed sugar-sweetened beverages (SSBs) intake in the highest tertile was associated with higher risk of Type 1 endometrial cancer (HRT3 vs T1 = 1.65; 95 % CI: 1.03-2.64). None of the beverages was associated with risk of breast or colorectal cancer. Conclusion: We conclude that, in this cohort, relatively high SCB intake was associated with higher risk of endometrial and ovarian cancers, but not of breast or colorectal cancers. Our findings also suggest that relatively high SSB and fruit juice intake are associated with higher risk of Type 1 endometrial cancer.

Combination of PdCl2 with 1,1,3,3-tetramethyldisiloxane in the presence of activated carbon was found to be an effective catalyst system for the cleavage reaction of C-O bond of O-t-Bu moieties. The present catalytic reaction offers a practical method for the deprotection of tert-butyl esters, tert-butyl ethers, O-Boc, and N-Boc derivatives under mild conditions. The addition of activated carbon in the reaction mixture was proved to be crucial for not only sustaining the catalytic activity but also trapping the palladium species after the reaction.

COA of Formula: C13H8O2

Treatment of 2-arylbenzoic acids with N-chlorosuccinimide (NCS) and NaI at 70 degrees C under fluorescent lighting condition gave the corresponding 3,4-benzocoumarins in good yields under transition-metal-free condition. It was found that the reactivity of NCS with NaI for the formation of 3,4-benzocoumarins from 2-arylbenzoic acids was as high as that with NIS. Thus, the formation of carboxyl radicals and their cyclization onto an aromatic ring from 2-arylbenzoic acids with much less expensive NCS and NaI, than NIS could be successfully carried out to form 3,4-benzocoumarins.

The aroma-retention capacity of functional whey protein aggregates (WPA) was compared to that of native whey protein isolate (WPI) in aqueous solutions and in fat-free yogurts. The retention of aroma compounds, constituting a model strawberry aroma, was evaluated by calculating gas-matrix partition coefficients using head-space gas chromatography (HS-GC). The retention capacity of WPA differed from the one of WPI for three out of seven aroma compounds detected in HS-GC. Incorporating WPA in fat-free yogurts tended to decrease the release of hydrophobic aroma compounds such as 2-nonanone or methyl-cinnamate. The magnitude of the differences between the partition coefficients of yogurts enriched in WPI or WPA was lower than in aqueous solutions, which is likely to be due to the higher complexity of the food matrix and potential interactions with other ingredients. Overall, the different aroma-retention capacities of native WPI and functional WPA are likely to lead to unbalanced aroma, especially in fat-free dairy products.

A series of triphenylamine derivatives bearing a methoxycarbonyl group at the meta-position of the benzene ring were synthesized. The structural and physical properties based on the introduction of the methoxycarbonyl group into benzene ring were investigated by single crystal X-ray diffraction, computational studies, and spectroscopic methods. It was revealed that the methoxycarbonyl group has not only structural regulations but also modifications of the electronic properties of the pi-conjugated moieties.

The condensation of MeP(SiMe3)(2) with a series of 5-substituted isophthaloyl chlorides (5-R’C6H3-2,6-{C(O)Cl}(2)) affords the diphosphametacyclophanes m-{-C(O)-C6H3-5-R’-(C(O)PMe)}(2) (R’ = I, Me, tBu, Ph, and p-NCC6H4); the analogues m-{-C(O)-C5H3N-(C(O)PMe)}(2) and m-{-C(O)-C6H4-(C(O)PPh)}(2) are similarly obtained in preference to higher oligomers, in contrast to precedent reports. The cyclophanes all adopt butterfly-like conformations in the solid state with the P-organyl substituents adopting mutually exo arrangements. Structural and computational data suggest the nature of the 5-R substituent is key in directing the inter-ring angle and the extent of LUMO stabilization about the diketophophanyl scaffold. The latter is substantiated by UV/vis spectroscopy and cyclic voltammetry, which demonstrate these cyclophanes to be appreciably comparable to the diketophosphanyl systems commonly explored in the context of organic electronic materials; intriguingly, the distinct dikeophosphanyl moieties within the macrocycles appear effectively insulated by the macrocycle geometry, rather than acting as a through-conjugate.

By using 2-fluoro-substituted diaryliodonium salts, a novel benzocylization has been accomplished for the synthesis of 3,4-benzocoumarin derivatives via a cascade of ortho-arylation and defluorination in the presence of palladium catalysts. The reaction exhibits a broad compatibility of readily available aromatic acids with an excellent level of site-selectivity. Mechanistic investigations revealed a unique reactivity of carboxylic acid directed arylation by followed nucleophilic substitution of aromatic fluoride in the present system.

A convenient method for performing a thiol-ene reaction is described. The reaction is performed under blue-light irradiation and catalyzed by photoactive Lewis basic molecules such as acridine orange or naphthalene-fused N-acylbenzimidazole. It is believed that the process is initiated by a proton-coupled electron transfer process within the complex between the thiol and the Lewis basic catalyst.

The practical problems of insufficient mechanical strength, poor processability, tedious synthesis and flammability facing shape memory polymers have limited their further usage in industrial fields, especially in construction and aerospace. A novel and very simple method of ternary polymerization is presented here to prepare multi-functional copolyesters from general poly(ethylene terephthalate) (PET) through the new well-designed third monomer that features pendent phenylacetylene-phenylimide units. The pi-pi stacking between phenylacetylene groups as a reversible net-point not only endows the copolyesters with good shape memory and self-healability, but also reinforces the interchain interaction, leading to high tensile strength (79.6-89.6 MPa). Interestingly enough, the phenylacetylene can synergistically crosslink with the unsaturated C N group generated from the phenylimide during burning, resulting in excellent flame retardancy. Thermoplastic smart copolyesters can be designed into fire alarms and can also be used for 3D printing. The printed geometries exhibit good shape memory behaviors, which could be deformed into a small size to save space during transportation/storage and allow manufacturing freedom for space applications.
