AbstractPantetheinase, also known as Vanin-1, catalyzes pantetheine to decompose into the precursor of CoA — pantothenic acid and aminothiol cysteamine. Studies have shown that Vanin-1 plays an important role in many important physiological pathologies. In this paper, a new red emission ratio fluorescent probe DCM-PA (I640 nm/I564 nm) has been implemented to detect the activity of Vanin-1 in cells and vivo. DCM-PA has short response time (30 min), high selectivity and low sensitivity (DL =0.69 ng/mL). Also, we have applied DCM-PA for imaging in cells and mice, and the results have indicated that the probe has a non-negligible potential for monitoring the activity of Vanin-1 in situ, benefiting further to study the role of Vanin-1 in physiology and pathology. In addition, the up-regulation of this enzyme by starvation confirmed the inevitable connection between diabetes and abnormal expression of Vanin-1. © 2020 Elsevier B.V.
