Peptide 74 是一种合成肽，含有基质金属蛋白酶 (MMP) 的前域序列。Peptide 74 在体外抑制活化形式的 72-kDa IV 型胶原酶。
Peptide 74 is a synthetic peptide containing the prodomain sequence of matrix metalloproteinase (MMP). Peptide 74 inhibits the activated form of the 72-kDa type IV collagenase in vitro[1].
Peptide 74 (30 μM) reduces both A2058 and HT 1080 tumor cell invasion by 60-80%[1]. Peptide 74 (30 μM) shows no cytotoxic action and does not inhibit chemotaxis or affect HT1080 and A2058 human tumor cells number[1].
