Thymopentin is a thymic polypeptide derivative which interacts with T cells and acts as an immunostimulant. [1] [2] [3] [4] As such, it was used in several clinical studies in the early years of the AIDS pandemic (from 1983 to 1985). Thymopentin helped to improve immunological condition in some patients for a brief time under specific treatments. [5] [6] [7] It has also been investigated more recently for applications in the treatment of rheumatoid arthritis, [8] and lung cancer. [9]
