Abstract

High levels of homocysteine (Hcy) is closely associated with the onset of cerebral infarction. The present study aimed to synthesize a novel Hcy probe based on Rhodamine B, named S1‑4, a new compound that has not been previously reported. This probe exhibited good linear range under physiological fluid viscosity and pH; it has good selectivity for Hcy, and is able to avoid interference from other amino acids and metal ions. This probe can effectively measure the level of Hcy in the blood sera of healthy people and in patients with transient cerebral ischemia and cerebral infarction. However, satisfactory specificity and sensitivity to Hcy was not achieved according to receiver operating characteristic curve analysis. Overall, results from the present study suggested that following further optimization, this probe may be potentially applied in the diagnosis of cerebral infarction.
