2-硫胞苷是从大肠杆菌| tRNA的水解物中分离出的核苷碱基。 2-Thiocytidine 是一种嘌呤核苷类似物。嘌呤核苷类似物具有广泛的抗肿瘤活性，靶向惰性淋巴系统恶性肿瘤。这一过程中的抗癌机制依赖于抑制 DNA 合成，诱导细胞凋亡 (apoptosis) 等 2-Thiocytidine is a nucleoside base that has been isolated from hydrolyzates of|Escherichia coli|tRNA. 2-thiactidine is a nucleoside base isolated from the hydrolysate of E. coli | tRNA； 2-Thiocytidine is a purine nucleoside analogue. Purine nucleoside analogues have extensive antitumor activity and target malignant tumors of the inert lymphatic system. The anti-cancer mechanism in this process depends on inhibition of DNA synthesis, induction of apoptosis, etc Application： 2-Thiocytidine is a cytidine analogue. A profiled metabolite in HFD-induced obese mice after oral administration of Huangjinya green tea extract.
