14523936-1	2003	Following the first synthesis of tritiated alpha-melanocyte-stimulating hormone (alpha-MSH, alpha-melanotropin) in 1974 by Medzihradszky et al., several alpha-MSH analogs were designed containing between 2 and 12 tritium atoms, the latter of which displayed a specific radioactivity of 12.21 GBq/micromol (330 Ci/mmol).	GBQ	292-295	pro-opiomelanocortin-alpha	Mus musculus	153-162	
14523936-2	2003	Similarly, radioiodinated alpha-MSH analogs of high purity, full biological activity and a specific radioactivity of approximately 140 GBq/micromol were obtained.	GBQ	135-138	pro-opiomelanocortin-alpha	Mus musculus	26-35
