Abstract
Spermidine은 spermine의 전구체로 역할을 하는 putrescine로부터 합성되는 polycation의 한 형태이다. 최근에 spermidine는 수명연장에 중요한 역할을 하는 하나의 polyamine으로 알려져 있다. Hydroxyl radical, superoxide 및 hydrogen peroxide와 같은 활성산소(ROS)는 노화뿐만 아니라 다양한 병원성 과정에서 관여한다고 보고되고 있다. DPPH radical, <TEX>$H_2O_2$</TEX> 및 hydroxyl radical에 대한 spermidine의 소거활성과 산화적 스트레스와 관련된 DNA oxidation에 대한 보호 효과가 in-vitro에서 평가되었다. Spermidine은 500 <TEX>${\mu}M$</TEX> 이상에서 DPPH radical와 <TEX>$H_2O_2$</TEX>에 대한 소거 효과를 보여주었다. 특히 활성산소종 중에서 spermidine는 hydroxyl radical에 대한 효과가 탁월하였다. 뿐만 아니라, spermidine는 500 <TEX>${\mu}M$</TEX>에서 DNA oxidation에 대해서도 뚜렷한 보호 효과를 나타내었다. 더욱이 사람피부섬유아세포에서 superoxide dismutase와 같은 항산화 관련 단백질의 발현이 대조군과 비교시 spermidine 존재 하에 증가하였다. 이상의 결과로부터 spermidine은 암, 노화 및 염증을 포함하는 활성산소와 관련 있는 질병들을 예방하기 위한 항산화제로 이용될 수 있을 것이다. Spermidine is a ubiquitous polycation that is synthesized from putrescine, which serves as a precursor of spermine. In recent years, spermidine was found to be a polyamine that plays an important role in longevity. Reactive oxygen species (ROS) such as hydroxyl radical, superoxide and hydrogen peroxide have been shown to be involved in various pathogenic processes as well as aging. The direct scavenging effect of spermidine on DPPH radical, <TEX>$H_2O_2$</TEX> and hydroxyl radical, and its protective effect against DNA oxidation related to oxidative stress were evaluated in vitro. It was observed that spermidine exhibits scavenging activities on DPPH radical and H2O2 above 500 <TEX>${\mu}M$</TEX>. Spermidine was especially effective in exerting a scavenging activity on hydroxyl radical. In addition, spermidine at 1000 <TEX>${\mu}M$</TEX> showed a clear protective effect against DNA oxidation. Furthermore, the expression level of anti-oxidant enzymes such as superoxide dismutase in humam dermal fibroblasts increased in the presence of spermidine compared with blank group. These results suggest that spermidine can be used as an antioxidant to prevent ROS-related diseases including inflammation, cancer and aging.
