2-Furoic acid (Furan-2-carboxylic acid) 2-Furoic acid can reduce serum cholesterol and triglyceride levels and has anti-lipidemic effects.

含微量5-HMFA和Furan-2-carboxylic acid的Agar能抑制培养皿中某些生长缓慢或难以培养细菌的增殖[1]。

2-Furoic acid选择性地抑制了破骨细胞的骨吸收活动，并且防止了由雌激素缺乏引起的骨质流失，但不影响骨骼形成。作为一种口服活性的选择性人类Cathepsin K抑制剂，2-Furoic acid可能对于治疗由过度骨质流失所特征的疾病具有治疗潜力，包括骨质疏松症[2]。

The inhibitory effects of 5-HMFA, FA, and a mixture of the furan-2-carboxylic acids on the swarming and swimming of P. collierea V5-G'5 were assayed on MW solid medium (pH 6.0) containing 0.3% washed agar. The concentrations of these compounds were determined by the concentrations found in 0.3% agar plates (1×), and a series of two fold dilutions ranging from 0.125× to 8× was tested. As 5-HMFA and FA remained in the washed agar at concentrations of 0.07 and 0.12 μg g?1 agar, respectively, the 0.3% agar medium supplemented with 0.125× furan-2-carboxylic acids, contained 0.32 ng mL?1 and 0.51 ng mL?1 FA, respectively[1].

When given orally twice daily for 4 weeks to 3-month-old ovariectomized (OVX) rats, Furan-2-carboxylic acid dose-dependently prevented bone loss, as monitored by bone densitometry, ash content, and urinary excretion of deoxypyridinoline.?No change in serum osteocalcin in the OVX rats by Furan-2-carboxylic acid suggested that bone formation might not be affected by the agent[2].
