The presented work, submitted as a paper, deals with the substitution reactions of mononuclear and dinuclear platinum(II) complexes of di-2-pyridylaminodiaquaplatinum(II), (Pt1); di-2-pyridylaminomethylbenzenediaquaplatinum(II), (Pt2); 1,2-bis(di-2-pyridylaminomethyl)benzenetetraquaplatinum(II), (Pt3); 1,3-bis(di-2-pyridylamino-methyl)benzenetetraquaplatinum(II), (Pt4); and 1,4-bis(di-2-pyridylaminomethyl)-benzenetetraquaplatinum(II), (Pt5). These reactions were carried out on aqua complexes by three nucleophiles, viz., thiourea, N,N?-dimethylthiourea, and N,N,N?N?-tetramethylthiourea under pseudo?first-order conditions as a function of nucleophile concentration and temperature by stopped-flow and UV?visible spectrophotometric techniques. In addition, some DFT calculation was performed. The activation parameters support an associative substitution mechanism.

Background: Fat perception and liking are the subjects of growing interest from industries and the scientific community to reduce the fat content in food products while maintaining consumers? liking. Scope and approach: In this review, the different physiological parameters involved in fat perception and fat liking for food emulsions are explored, focusing on spreads. A deeper analysis of the physiological mechanisms occurring during the melting and inversion phases, followed by bolus formation, mouth coating and oral clearance, allows an examination of the links between food composition, food structure, oral physiological parameters, fat perception and liking. Key findings and conclusions: Fat perception is a multimodal sensation involving olfactory, gustatory and tactile cues. The main sensory descriptors associated with fat liking are creaminess, spreadability and aroma perception. During the melting and inversion phases, oral volume, saliva flow and tongue-palate compression contribute to the heat transfer and cooling effect, leading to the first sensory perception. Global acceptability is also driven by the mouthfeel sensation perceived after swallowing. Mouthfeel is a consequence of the bolus formation, mouth coating and oral clearance processes that are dependent on both emulsion composition and oral physiological parameters (saliva flow, saliva composition, fungiform papillae). Understanding the physiological mechanisms controlling fat perception can lead to a better understanding of the consumer’s preference and liking for food emulsions.

The first total synthesis of pelargonidin 3-O-6?-O-acetyl-beta-d-glucopyranoside, an acylated anthocyanin of magenta-colored Verbena flowers, was successfully carried out. The key intermediate, protected kaemferol 3-O-glucoside, was constructed by the Baker-Venkataraman rearrangement from a glucosyloxyacetophenone followed by Zn-Hg reduction to the corresponding acylated anthocyanin.

Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 10343-06-3, C14H20O10. A document type is Article, introducing its new discovery.

A series of dihydroartemisinin derivatives containing a sugar moiety was prepared in the search for analogues with good water solubility and high antimalarial activity. The preparation of the new compounds were achieved by treatment of dihydroartemisinin (2) with chlorotrimethylsilane in pyridine solution at -10 C to give a nearly quantitative yield of 10-O- (trimethylsilyl)dihydroartemisinin (3), which was then condensed with 1- hydroxypolyacetylated sugars 5 to give dihydroartemisinin derivatives 7a-d. Deacetylation of intermediates 7 gave the desired sugar derivatives 8. The resulting derivatives, tested in vitro against Plasmodium falciparum, were found to be more effective against W-2 than D-6 clones and were not cross- resistant with existing antimalarials. Trimethylsilylated compound 3 is more effective than derivatives 7a-d, which possess activity comparable to or better than that of artemisinin itself. Deacetylated compounds 8a-d were substantially less active than 7 in both cell lines. In P. berghei-infected mice, 7a-c showed 5/5, 2/5, and 3/5 cures, respectively, at 320 mg/kg per day x 3, whereas 7d showed no activity at the same dosage. However, 7d did prolong the life span in 3/5 of the infected mice at 640 mg/kg per day x 3 dose level. Trimethylsilylated compound 3 was also the most effective among the compounds studied, with 5/5 cures at 80 mg/kg per day x 3. The deacetylated sugar derivatives 8a-d showed only slight in vivo antimalarial activity.
