The concise synthetic approach enables access to the natural products in a sequence of 8-12 steps from readily available building blocks. Highlights of the synthetic strategy include gram-scale preparation of a late stage intermediate, pinpoint stereocontrol around the tricyclic skeleton, and a modular strategy that enables analogue generation. A key bicyclic β-lactam intermediate not only serves as the key controlling element for pyrrolidine stereochemistry but also serves as a preactivated coupling partner to install the ester side chain. The stereocontrolled synthesis allowed for the investigation of the antimicrobial activity of batzelladine D, demonstrating promising activity that is more potent for non-natural stereoisomers.}, number={21}, journal={JOURNAL OF THE AMERICAN CHEMICAL SOCIETY}, author={Lin, You-Chen and Ribaucourt, Aubert and Moazami, Yasamin and Pierce, Joshua G.}, year={2020}, month={May}, pages={9850–9857} } @article{parker_oh_moazami_pierce_loziuk_dean_muddiman_2016, title={Examining ubiquitinated peptide enrichment efficiency through an epitope labeled protein}, volume={512}, ISSN={["1096-0309"]}, DOI={10.1016/j.ab.2016.08.017}, abstractNote={Ubiquitination is a dynamic process that is responsible for regulation of cellular responses to stimuli in a number of biological systems. Previous efforts to study this post-translational modification have focused on protein enrichment; however, recent research utilizes the presence of the di-glycine (Gly-Gly) remnants following trypsin digestion to immuno-enrich ubiquitinated peptides. Monoclonal antibodies developed to the cleaved ubiquitin modification epitope, (tert-butoxycarbonyl) glycylglycine (Boc-Gly-Gly-NHS)1, are used to identify the Gly-Gly signature. Here, we have successfully generated the Boc-Gly-Gly-NHS modification and showed that when conjugated to a lysine containing protein, such as lysozyme, it can be applied as a standard protein to examine ubiquitinated peptide enrichment within a complex background.}, journal={ANALYTICAL BIOCHEMISTRY}, author={Parker, J. and Oh, Y. and Moazami, Y. and Pierce, J.

Although significant effort has been focused on the study of crude Echinacea extracts, very little is known regarding the activities of the individual constituents that make up these herbal treatments. Herein we explore the SAR of simple alkylamides found in Echinacea extracts with respect to their ability to decrease the production of the pro-inflammatory mediator TNF-α. Our results have revealed the key structural requirements for activity and provide lead compounds for further investigation of these poorly understood molecules.}, number={16}, journal={BIOORGANIC & MEDICINAL CHEMISTRY LETTERS}, author={Moazami, Yasamin and Gulledge, Travis V. and Laster, Scott M. and Pierce, Joshua G.}, year={2015}, month={Aug}, pages={3091–3094} } @article{moazami_pierce_2015, title={Synthesis of 2,3-Dihydro-1,3-oxazin-4-ones via a Mild Formal [4+2] Cycloaddition of Acylketenes with Aldimines}, volume={47}, number={21}, journal={Synthesis (Stuttgart)}, author={Moazami, Y. and Pierce, J.
