Tightly regulated cysteine CA proteases play a major role in maintaining the homeostasis within cells. Subsequently, when these proteases are dysregulated and mislocalized they disrupt healthy cell dynamics and contribute to many life-threatening pathologies such arteriosclerosis, osteoporosis and cancer. As such many pharmaceutical companies and research teams are highly interested in these proteases as targets. One emergent strategy is the spatiotemporal control of biological processes. In relation to this, a series of spatiotemporally controlled …

Facile Synthesis Of Tertiary Aliphatic Amine– Containing Cyclic Motif Via Neutral Aminyl Radical Cyclization, Heng Chen

Wayne State University Theses

Tertiary amine–containing cyclic motifs are prevalent in natural products and pharmaceutical lead targets. Inspired by these biological active molecules, one focus in our lab is the development of neutral aminyl radical chemistry in the synthesis of tertiary aliphatic amine–containing cyclic compounds. In this project, I investigated the mono- and tandem cyclization of aminyl radical with different types of olefins (terminal olefin, enone, and styrenyl). The effect of the hydrogen atom donor and the limitation of the reaction will be discussed.

Apoptosis is the energy dependent programmed cell death. Improper function of apoptosis could lead to diseases such as cancers, strokes, Alziemer’s disease. Caspases are the enzymes involved in the later stage of this process. Peptidyl and non-peptidyl caspase inhibitors have been synthesized recently. These non-peptidyl compound classes which consist of pyrrolidinyl-5-sulfo isatins have showed a greater potency against executioner caspases, caspase-3 and -7. According to literature and for further …
