The π-conjugated P-flowers C16(PH)8 and C16(PF)8 are potential materials for organic n-type semiconductors.
Following the theme of this special issue, two new compounds, the P-flowers C(16)(PH)(8) and C(16)(PF)(8), are designed by us and subsequently characterized by quantum chemical computations. Their geometries and infrared signatures are analyzed and compared to those of the well-known sulflower C(16)S(8). Their electronic structure and aromaticity are examined using the electron localization fun...
متن کاملTotal synthesis and biological evaluation of C16 analogs of (-)-dictyostatin.
The structure-activity relationship of the crucial C16 region of (-)-dictyostatin was established through total synthesis of analogs followed by detailed biological characterization. A versatile synthetic strategy was used to prepare milligram quantities of 16-normethyldictyostatin, 16-epi-dictyostatin, and the C16-normethyl-C15Z isomer. Along the way, a number of other E/Z isomers and epimers ...
متن کاملThe lipids C2- and C16-ceramide form large stable channels. Implications for apoptosis.
We report that physiological concentrations of both short- and long-chain ceramides, despite being lipids, form large stable pores in membranes. Some of these pores should be large enough to allow cytochrome c to permeate. Dihydroceramide differs from ceramide by the reduction of one double bond, and yet both its apoptogenic and channel-forming activities are greatly reduced. A structural model...
متن کاملA novel unsaturated fatty acid hydratase toward C16 to C22 fatty acids from Lactobacillus acidophilus.
Hydroxy FAs, one of the gut microbial metabolites of PUFAs, have attracted much attention because of their various bioactivities. The purpose of this study was to identify lactic acid bacteria with the ability to convert linoleic acid (LA) to hydroxy FAs. A screening process revealed that a gut bacterium, Lactobacillus acidophilus NTV001, converts LA mainly into 13-hydroxy-cis-9-octadecenoic ac...
متن کاملClassification of bacterial viruses: characteristics of the T5 species and of the T2, C16 species.
Criteria for the classification of bacterial viruses were proposed by Burnet (1933), including particle size, serological relationship, and certain physiological characteristics. These criteria were applied to the definition of 12 serological groups of coli-dysentery phages. This taxonomic scheme was an important advance since it embodied the concept of phylogenetic relationships among the bact...
