NCIt definition : An orally bioavailable synthetic peptide containing the amino acids D-glutamine and
L-tryptophan connected by a gamma-glutamyl linkage with potential immunostimulating,
antimicrobial and antineoplastic activities. Although the exact mechanism of action
is unknown, golotimod appears to inhibit the expression of STAT-3, reversing immunosuppression
and stimulating an anti-tumor immune response. This agent may stimulate the production
of T-lymphocytes, in particular the helper T (Th1) cells, activate macrophages, and
increase levels of interleukin 2 and interferon gamma. STAT-3, a transcription factor
upregulated in many cancer cell types, is involved in tumor cell growth and survival
and immunosuppression.;
