Fetuin, Fetal Bovine Serum is a glycoprotein weighing 64 kDa that is secreted by the liver and obtained from fetal bovine serum. It acts as an inhibitor of trypsin activity and facilitates cellular attachment, growth, and differentiation.

Benzoylaconine (Isaconitine) is an alkaloid in the Chinese traditional medicine Radix Aconiti Lateralis Preparata (Fuzi). Benzoylaconine and aconitine can induce reproductive toxicity in BeWo Cell, the amino acid metabolism was the main metabolic pathway and responsible for the placental and fetal toxicity of them.

Estetrol(Donesta) is an orally available, selective modulator of the estrogen receptor, a naturally occurring estrogen synthesized by the human fetal liver during pregnancy.Estetrol has effects on the endometrium or central nervous system, but is antagonistic to the breast.Estetrol may help to reduce thrombosis at low concentrations. Estetrol may be used to relieve menopausal symptoms.

Allocholic acid is a fetal bile acid found in vertebrates and reappears during liver regeneration and carcinogenesis. It is also a potent and specific stimulant of the adult olfactory system.

D-Tagatose (D-(-)-Tagatose), a rare natural hexoketose, is an isomer of d-galactose. D-Tagatose occurs naturally in Sterculia setigera gum, and it is also found in small quantities in various foods such as sterilized and powdered cow's milk, hot cocoa, and a variety of cheeses, yogurts, and other dairy products. It can be synthesized from D-galactose by isomerization under alkaline conditions in the presence of calcium. D-Tagatose have numerous health benefits, including promotion of weight loss, no glycemic effect, anti-plaque, non-cariogenic, anti-halitosis, prebiotic, and anti-biofilm properties, organ transplants, enhancement of flavor, improvement of pregnancy and fetal development, treatment of obesity, and reduction in symptoms associated with type 2 diabetes, hyperglycemia, anemia, and hemophilia.

Vitexolide D shows moderate antibacterial activity against a panel of 46 Gram-positive strains. It also shows cytotoxic activities against the HCT-116 cancer cell line and human fetal lung fibroblast MRC5 cell line (1 < IC50s < 10 uM).

cis-Vaccenic acid (Asclepic acid) is the antiviral extract from Rhodopseudomonas capsulate and the predominant active component of Rhodopseudomonas capsulate. cis-Vaccenic acid acts a potential fetal hemoglobin inducer.
