Dynamics and Turnover of Lipid and Protein Domains in Cells and Supported Bilayers
<p>Protein and lipid clustering is an important mechanism for cell processes such as exo- and endo-cytosis and creating functional signaling complexes. It has been seen that both lipids and proteins are involved with the formation of cluster domains on cell membranes, yet little is known about the …

ESIPT-Enabled Alkyne Migration Provides Rapid Access to Benzoxazinones
<p>Benozoxazinones have long been of interest to agrochemical scientists and medicinal chemists because of their widespread biological activity. These scaffolds are also of interest to synthetic chemists, who recognize the utility of benzoxazinones for accessing functionalized heterocycles. The use …

Polyol induced extraction (PIE) of water from organic solvents
… separation process was investigated using isothermal calorimetry. At 20 <sup>o</sup>C, ∆H<sup>o</sup> is exothermic (-2.06 kJ/mol) for glycerol induced phase separation in ACN-water system and -7.07 kJ/mol at -10 <sup>o</sup>C. Considering the glycerol/ACN/water system at -10 <sup>o</sup>C, …

Photoassisted Synthesis of Complex Polyheterocycles via Rational Design of Tailored Photoprecursors
… of azaxylylenes allows for the access to other derivatives of these complex molecules, with a particular focus on heterocycles. Also, the awareness of photoassisted intermediates via excited state intramolecular proton transfer helped us implement [4+2] cycloadditions, which gave us rapid …

Interaction of Spliceosomal U2 snRNP Protein p14 with Its Branch Site RNA Target
<p>Newly transcribed precursor messenger RNA (pre-mRNA) molecules contain coding sequences (exons) interspersed with non-coding intervening sequences (introns). These introns must be removed in order to generate a continuous coding sequence prior to translation of the message into protein. The …

Investigation of Host-Sensitized Luminescence of Trivalent Lanthanide Doped Yttrium Phosphate using VUV Spectroscopy
Host-sensitized luminescence of yttrium phosphate doped with trivalent lanthanide elements prepared via two synthetic approaches was studied using VUV spectroscopy. A correlation between an unusually intense 150 nm excitation intensity and the ground state energy level of select trivalent …

Syntheses of a Tin (IV) meso-Tetra(4-pyridyl) Porphyrin Dichloride-Tetrachlorobis (Bipy)2 Ruthenium (II) Complex and Studies of Photophysical Properties of 1-Nitropyrene
<p>Development of a photosensitizer that can work in both aerobic and anaerobic environments would increase the robustness of the cancer treatment known as photodynamic therapy. The development of a photosensitizer was first attempted by synthesizing a tin (IV) meso-tetra (4-pyridyl) porphyrin …

From the Making to the Tuning to the Use of Chlorins for Biomedical Applications
<p>Chlorins are porphyrins missing a double bond. These pigments are optimal platforms for the development of novel dyes that display drug-like attributes such as photodynamic therapy (PDT) agents. More recently, it was demonstrated that chlorins can serve both as a PDT agent and as a modality for …
