代谢
阿法瑞林(afamelanotide)的代谢和代谢产物的详细信息很少。这种药物比其内源性对应物α-MSH对血清和蛋白水解酶的降解更具抵抗力,但由于其半衰期较短,可能发生相对较快的 hydrolysis。有人提出,阿法瑞林可能以与α-MSH相同的方式降解,但速率要慢得多,或者可能通过内吞作用或非特异性蛋白酶在细胞内降解。
Details regarding the metabolism and metabolites of afamelanotide are sparse. The drug is more resistant to degradation by serum and proteolytic enzymes than its endogenous counterpart, α-MSH, but presumably undergoes a relatively rapid hydrolysis given its short half-life.[L9086,L9134] It has been suggested that afamelanotide may be degraded in the same manner as α-MSH but at a much slower rate, or may instead be degraded intracellularly via endocytosis or non-specific proteases.[A187202]
