生物活性 Azetidine-2-carboxylic acid is a non proteinogenic amino acid homologue of proline. Found in common beets. Azetidine-2-carboxylic acid can be misincorporated into proteins in place of proline in many species, including humans. Toxic and teratogenic agent[1][2].
In Vitro Administration of azetidine-2-carboxylic acid to growing chick embryos for 5 days produced a marked arrest in the accumulation of collagen and a significant in_x005fcrease in the fragility of the embryos.The effect on collagen in embryos treated with 375 or 500 ~g per day was specific since the decrease in collagen accumulation was consistently over twice the effect on non-collagen proteins. The experiments with cartilage in vitro demonstrated that the principal effect of azetidine-2-carboxylic acid in the first 2 h or so is to increase the intracellular pool of collagen because the collagen containing the analogue cannot be extruded at a normal rate.[3]
In Vivo Autoradiographs from the embryos labeled in vivo indicated that cells treated with azetidine-2-carboxylic acid for 5 days do not adapt to the repeated exposure to the analogue and they still do not extrude collagen containing the analogue at a normal rate. [3]

动物实验 Azetidine-2-carboxylic acid was dissolved in distilled water and 0.2 ml of solution in the appropriate concentration was applied to the air sack of the chick erabryos daily from day 8 to day 12. Control embryos received 0.2 ml of distilled water daily. [14C] Proline or ~3,4-3H21proline was administered by adding the labeled amino acid to the solution of azetidine-2-carboxylic acid or distilled water which was ad_x005fministered to the chick embryos 4-48 h prior to the time the embryos were killed. Femurs and tibiae were removed from the embryo by microscopic dissection.[3]
