It is a tetrahydro-imidazothiazole derivative (Figure S6) that has been used for its immunomodulatory properties. It was first introduced by Janssen in 1969. Ever since, it was used as a disease-modifying drug for the treatment of rheumatoid arthritis [222,223,224]. It was also used with 5-fluorouracil for colon cancer treatment [225]. Currently, it is primarily used as an anthelmintic agent for the treatment of ascariasis and hookworm infections owing to its effect on the parasitic nicotinic acetylcholine receptors [226]. It is also used by pediatric nephrologists as a steroid-sparing agent in childhood steroid-dependent nephrotic syndrome [227].
