Introduction: The NAD+dependent proteins deacetylases are called Sirtuins (SIRT). Objectives: Objectives: this review is to study the sirtuins involved in cancer, as well as SIRT1 inhibition studies in patients with coronavirus disease COVID-19. Data source and selection: For this, a search was made in Medline, Scopus and WOS, where descriptive studies of each of the functions of sirtuins were included, adjusted to recent scientific research. SIRT1 inhibition reduces CD8 T cell cytotoxicity in patients with systemic erythematosus lupus, being susceptible to SARS Cov-2 infections. SIRT2 is regulated by the secretion of IL-4 by eosinophils and the increase in SIRT2 increases hyperplasia, in contrast, SIRT3 promotes angiogenesis, inducing cardiac remodeling. SIRT4 is a tumor suppressor, in contrastto SIRT5 that promotes cell proliferation causing colorectal cancer; SIRT6 attenuates herpes virus associated with Kaposi\'s Sarcoma (KSHV) in immune compromised patients. Suppression of SIRT7 inhibits the growth of endometrial cancer cells. Conclusions: It is concluded that SIRT1, SIRT2 and SIRT4 are involved in the development of cancer, the suppression of SIRT5 and SIRT7 promotes the apoptosis of cancer cells and SIRT6 attenuates the replication of KSHV, in addition to the molecular pathology pathway of COVID-19 is associated with the inhibition of SIRT1 activity that may be related to inflammatory processes.
