Neoendorphin 100 is any of the variety of peptides found in neural tissue. These peptides are all released centrally and act on other neurons at specific receptors. Peptide signals play a role in information processing that is different to that of conventional neurotransmitters, and many appear to be particularly associated with specific behaviors. Neoendorphin 100 can directly bind to the kappa opioid receptor(KOR) on the plasma membrane of skin cells such keratinocyte and fibroblast. And then it induce a variety of biological events such as wound healing and skin retexturizing.

新内啡肽100是神经组织中发现的任何多肽。这些肽全部中枢释放，并作用于特定受体的其他神经元。肽信号在信息处理中起着与传统神经递质不同的作用，并且许多似乎与特定行为特别相关。新内啡肽100可以直接结合皮肤细胞如角质形成细胞和成纤维细胞的质膜上的κ阿片受体（KOR）。然后它会诱发各种生物事件，如伤口愈合和皮肤再次光照。
