Curcumin against advanced glycation end products (AGEs) and AGEs-induced detrimental agents.

OBJECTIVES

This study was aimed to review and collate effects of curcumin on generation of advanced glycation end products (AGEs) and AGEs induced detrimental agents.

METHODS

Pubmed, Googlescholar, ScienceDirect, and Scopus databases were searched. Searching was not limited to specific publication period. Only English language original articles (in vitro, experimental and human) which had examined the effect of curcumin on AGEs formation and AGEs induced apoptosis, oxidative stress or inflammatory responses were included. To review effect of curcumin on AGEs formation, search terms were as following: ''curcumin" (title) and AGEs or pentosidine or methylglyoxal or carboxymethyllysine or glucosylation (title/abstract). Totally 104 articles were searched which 19 were selected for review. To review effect of curcumin on AGEs induced harmful agents, key words were as following: "curcumin" (title) and AGEs (title/abstract) and apoptosis or oxidative stress or DNA damage or cell injury or inflammatory or cell death or cell proliferation (title/abstract). Totally 126 articles were searched which 18 were found appropriate for review.

RESULTS

Regarding curcumin and AGEs formation, ten eligible articles (1 human trial, 5 animal models and 4 in vitro) and with regarding curcumin and AGEs-induced complications, 17 articles (5 on apoptosis, 9 on oxidative stress, and 3 on inflammatory responses) were selected. Except one, all studies indicated that curcumin is able to prevent AGEs formation and AGEs-induced disturbances with different potential mechanisms.

CONCLUSION

Curcumin can inhibit AGEs formation and AGEs-induced disturbances. More RCT researches are suggested to evaluate beneficial effect of curcumin regarding AGEs in different age-related chronic diseases, with specific attention to AGEs memberships.
