Brett VanVeller
Boronic acids are versatile reagents for the chemical synthesis of organic molecules. They and other boron-containing compounds can be detected readily by the interruption of the excited-state intramolecular proton transfer (ESIPT) of 10-hydroxybenzo[h]quinolone. This method is highly sensitive and selective, and useful for monitoring synthetic reactions and detecting boron-containing compounds on a solid support.

Fluorescent sensors have been a main microscopic tools used to understand Zn2+ physiology on a cellular level. The use of the fluorescent Zn2+ sensor Zinquin (ZQ) and its analogues have revealed that transient Zn2+ is a chief component in a variety of biochemical pathways. Yet, little work has been performed to validate the exact targets of Zinquin in a cellular environment. The goals of this investigation are to determine the types of Zinquin reactions that take place in the cell as well as the identities of its cellular targets.
It has been hypothesized that Zinquin reacts with free Zn2+ within …

The objective of this study is to understand the structure of guanine nucleotide - binding (G) proteins using a variety of spectroscopic tools. G proteins are membrane-bound proteins consisting of α, β, and γ subunits required for the transduction of extracellular signals to various intracellular effectors. Activation of G protein coupled receptors by neurotransmitters or hormones result in a conformational change of a G protein that is triggered by the exchange of guanosine 5'- diphosphate (GDP) bound to the subunit for guanosine 5'- triphosphate (GTP) and concomitant dissociation of the dimer.
