Tricine can clearly visualize tumors, may as melanoma imaging agents. Using the combination of tricine and a phosphine ligand, HYNIC-derivatized peptides or other small molecules can be labeled with 99mTc in high specific activity and with high stability for potential use as radiopharmaceuticals.

5-hydroxy-1-tetralone as the fluorescent labeling reagent.

1-Methoxycarbonyl-beta-carboline-N-oxide is a natural product for research related to life sciences.
