Selection of Standardization Parameters and Development of Quality Control Methods for Isoleucyl-Tryptophan Dipeptide Coordination Complex with Iron(II) (Timofer)

Abstract

The coordination complex of the dipeptide isoleucyl-tryptophan with Fe(II) possesses immunostimulating activity and is effective for treating iron- and immunodeficiency and pulmonary, rheumatological, and urological diseases. Results are presented from the development of quantitative assays for isoleucyl-tryptophan– Fe(II) using the Fe(II) ion and the tryptophan indole moiety. The standardization parameters of a reference sample, drug substance, and its dosage form are determined.
