Cycloleucine (1-aminocyclopentane carboxylic acid) was shown to be quite active in preventing the clinical and histologic signs of experimental allergic encephalomyelitis and adjuvant arthritis. In contrast, it was inactive in two in vitro models designed to detect various types of clinically effective anti-inflammatory, anti-immune agents: tissue culture growth and polymorphonuclear leukocyte migration. Its immunopharmacologic spectrum differs from that of other clinically active agents, suggesting that it may work via a different mechanism or at a different site.
