Gitogenin 是一种从Tribulus longipetalus整株中分离出来的天然类固醇，是一种 UDP-葡萄糖醛酸转移酶 1A4 (UGT1A4) 和 α-葡萄糖苷酶的选择性抑制剂，其IC50分别为 0.69 μM (使用三氟拉嗪为底物) 和 37.2 μM，对人类主要细胞色素 P450 亚型的活性无抑制作用。

1. Gitogenin, tigogenin, and solasodine are novel selective inhibitors of UGT1A4, and do not inhibit the activities of major human CYP isoforms. 2. Gitogenin and (25S)-5α-furastan-3β, 22, 26-triol are the inhibitors of enzyme α-glucosidase with IC50 values of 37.2±0.18 and 33.5±0.22 uM, respectively.3. Gitogenin shows moderate stimulation of release activity on growth hormone from rat pituitary cells.
