Composition for detecting hydrogen sulfide or measuring hydrogen sulfide concentration and composition comprising same as effective ingredient for diagnosing or imaging in vivo inflammation, tissues having hypoxic damage, or cancer

Abstract

The present invention relates to a composition for detecting hydrogen sulfide or measuring a concentration of hydrogen sulfide, and a composition comprising same as an effective ingredient for diagnosing or imaging in vivo inflammation, tissues having hypoxic damage, or cancer. The composition for detecting hydrogen sulfide or measuring a concentration of hydrogen sulfide according to the present invention, which comprises the compound represented by formula 1 (99mTc-alpha-hydroxy acid) having alpha-hydroxy acid labeled with 99mTc, enables the detection or concentration measurement of hydrogen sulfide in in-vitro and in-vivo levels and, as such, can be advantageously used for detecting hydrogen sulfide and measuring a concentration of hydrogen sulfide and furthermore for discovering biological roles of hydrogen sulfide in vivo, especially, for detecting, imaging, and quantitatively measuring hydrogen sulfide in a disease selected from the group consisting of angiogenesis, inflammation, cancer, Alzheimer's disease, cardiovascular ischemia, and cerebrovascular ischemia, or in hypoxic tissues.
