Research has confirmed that the Nle4 and D-Phe7 substitutions in MT-1 produce substantially extended in vitro and in vivo stability relative to native -MSH , documenting resistance to endopeptidase cleavage at the position 7 Phe bond and prevention of methionine oxidation that inactivates native -MSH, resulting in prolonged receptor occupancy and sustained downstream signalling

There is currently no effective means of prevention of Vulvar Melanotic Macules, because the cause of this condition is unknown

However, the majority of TMAO is excreted unchanged in the urine within 24 hours, with only a small amount excreted in the feces (72) ( Figure 1 )
