Chronic inflammation and autoimmunity play a pivotal role in carcinogenesis. Some studies, indeed, have pointed out the presence of AITD as a risk factor for TC, although this issue remains controversial. Prevention of autoimmune disease and cancer is the ultimate goal for clinicians and scientists, but it is not always feasible. Thus, new treatments, that overcome the current barriers to prevention and treatment of TC and AITD are needed. Alkaloids are secondary plant metabolites endowed with several biological activities including anticancer and immunomodulatory properties. In this perspective, alkaloids may represent a promising source of prophylactic and therapeutic agents for TC and AITD. This review encompasses the current published literature on alkaloids effects on TC and AITD, with a specific focus on the pathways involved in TC and AITD development and progression.  \nKeywords: alkaloids; drug discovery; thyroid cancer cell lines; thyroiditis; cell proliferation; apoptosis; anti-cancer agent  \n1. Introduction  \nAlkaloids are naturally organic compounds containing at least one basic nitrogen atom. These compounds are found primarily in plants as secondary metabolites and are important for plants in the defense against herbivores and pathogenic organisms [1] . Alkaloids have been classified, based on their heterocyclic ring system and biosynthetic precursor, into several groups, including imidazole, indole, isoquinoline, piperidine, pyrrolidine, pyrrolizidine, quinoline, quinolizidines, steroid, tropane, and terpenoid alkaloids [2,3] . Alkaloids have been intensely investigated because of their biological activity and therapeutic potential. They possess, indeed, a broad spectrum of biological activities [4], including antiinflammatory, anti-oxidant, anti-microbial, anticholinergic, analgesic, antiangiogenic [5], anti-cancer [6,7], and immunomodulatory properties [8] . Some alkaloids, such as Vinca alkaloids, Quinolines (camptothecin and its derivatives), and Taxanes (paclitaxel and docetaxel) have been used to treat cancer since the 1960s [9], beyond their traditional use. Currently, a large number of plant derivatives are under investigation for positioning and“repurposing” in cancer the","cbCaimF5w2x9pNJc","https://ap.wps.com/l/cbCaimF5w2x9pNJc","pdf",3306598,18,"English","# 1.
