title: Synthesis of N-arylsulfonyl DL-phenylserine derivatives exhibiting anti-inflammatory activity in experimental studies.
abstract: Synthesis and evaluation of anti-inflammatory activity in rats with adjuvant arthritis of aryl sulfonyl derivatives of nonproteinogenic aromatic amino acids is reported. The studied compounds were synthesized by introducing residues of benzene-, p-toluene-, and p-bromobenzene sulfonic acids into threo-DL-phenylserine and erythro-DL-p-nitrophenylserine structures. From the set of 12 compounds tested in animal screening, N-(p-bromobenzenesulfonyl)-erythro-DL-p-nitrophenylserine ethyl ester 12 demonstrated the most pronounced anti-inflammatory activity. This compound inhibited inflammation process in polyarthritis phase by 53% (P < 0.001) though it was slightly toxic (LD50 > 6,000 mg kg(-1) for mice).
