Department of Chemistry Ming Xian Research Group

Welcome to the Xian Group

Our group is working on the interface between chemistry and biology. We are especially interested in the research related to signaling molecules. Redox signaling molecules such as nitric oxide (NO) and hydrogen sulfide (H2S) play important roles in a number of physiological and pathophysiological processes. The detailed understanding of their biological functions is challenging because these molecules are very reactive and can undergo many possible biochemical reactions to form complicated products. Our long-term goal is to understand the fundamental mechanisms of NO and H2S related to their functions. In this field researchers have limited access of tools to mimic biological generation of these signaling molecules and monitor their fates in biological systems. Our lab has been actively exploring such chemical tools and has identified some promising candidates. We hope our efforts will ultimately lead to a better understanding of the significance of NO and H2S and initiate new strategies of related therapy.
Our lab is located in Fulmer Hall (rooms 468, 476, 478, 480, and 482). We enjoy our research and life in the beautiful Pullman campus. You are welcome to visit our group! Thank you for visiting the website of Dr. Ming Xian’s group!
