Pincher cationic ferrocene hosts for carboxylate ion guests were synthesized and the binding constants were determined by NMR or UV-Vis titrations. These (di)cationic hosts form tight complexes with benzoate or acetate even in competitive aqueous DMSO solvent. A bis(acylguanidinium) ferrocene dication achieves a remarkable Ka of ?106 M-1 to acetate in 9 : 1 DMSO-H2O and a Ka of 850 M-1 in neat D2O, one of the highest association constants known for a carboxylate complex exploiting only electrostatic interactions in neat water. DFT computations of the binding enthalpy are in good agreement with the experimentally determined association constants. The ferrocene backbone used in these pincher complexes may prove to be a useful semi-flexible scaffold for redox detectable/switchable self-assemblies in aqueous solutions.

Rainbow trout bone proteins were prepared by heating at 121C for 30 min, followed by filtration, concentration, and lyophilization. Nutritional properties and flavor analyses of hydrolysates digested by five different enzymes were investigated, respectively. Results showed that the crude protein content of rainbow trout bone was 15.90% and had a well-balanced nutritional value. The content of total amino acids was 983.64 mg/g. The amount of free amino acids of hydrolysates digested by alkaline protease, neutral protease, flavourzyme, papain, and trypsin for 3 hr was 207.83, 224.13, 1,001.59, 283.26, and 303.64 mg/g, respectively. During the hydrolysis, the main flavor compounds were identified by GC-MS to be alcohols, aldehydes, ketones, acids, and alkanes. After hydrolysis, the main molecular weight of peptides was focused on the range of 1,000?3,000 Da in all enzymatic hydrolysates. This study provided a theoretical basis to comprehensive utilization of rainbow trout bone in food industry.

For adult women in the United States, breast cancer is the most prevalent form of cancer. Compounds that target dysregulated signal transduction can be efficacious anti-cancer therapies. A prominent signaling pathway frequently dysregulated in breast cancer cells is the Wingless-related integration site (Wnt) pathway. The purpose of the work was to optimize a ?hit? from a screening campaign. 76,000 compounds were tested in a Wnt transcription assay and revealed potent and reproducible ?hit,? compound 1. Medicinal chemistry optimization of 1 led to more potent and drug-like molecules, 19, 24 and 25 (i.e., Wnt pathway IC50 values = 11, 18 and 7 nM, respectively). The principal results showed compounds 19, 24 and 25 were potent anti-proliferative agents in breast cancer cell lines, MCF-7 (i.e., IC50 values = 10, 7 and 4 nM, respectively) and MDA-MB 231 (i.e., IC50 values = 13, 13 and 16 nM, respectively). Compound 19 synergized anti-proliferation with chemotherapeutic Doxorubicin in vitro. A major conclusion was that compound 19 enhanced anti-proliferation of Doxorubicin in vitro and in a xenograft animal model of breast cancer.
