Aloesin as a medical food ingredient for systemic oxidative stress of diabetes.[Pubmed:26265996]

World J Diabetes. 2015 Aug 10;6(9):1097-107.

Diabetes is a chronic disease that requires a long term management where oxidative stress plays a pivotal role in disease progression and intensifying secondary complications. In spite of all the research on diabetes and recent advances in diabetes treatments, the reality is that there is no cure for diabetes and its devastating complications. While currently available anti-diabetic therapies are effective in reducing blood glucose level, they are not without associated side effects when they are used for a long term applications. As a result, physicians and patients are inclining more towards to a safer therapy with less serious side effects in the form of medicinal foods and botanical alternatives that are suitable for chronic usage. Aloesin, an Aloe chromone, has previously been formulated with an aloe polysaccharide to give a composition called Loesyn, where it showed significant impact in reducing glycosylated hemoglobin, fasting blood glucose, fructosamine and plasma insulin level in humans. Radical scavenging activities of chromones and polysaccharides from Aloe have also been reported. Here we rationalize the relevance of use of Aloesin alone or in a standardized blend with Aloe polysaccharides, as a potential medical food to manage systemic oxidative stress and/or high blood glucose of diabetes.

Aloesin Suppresses Cell Growth and Metastasis in Ovarian Cancer SKOV3 Cells through the Inhibition of the MAPK Signaling Pathway.[Pubmed:28702312]

Anal Cell Pathol (Amst). 2017;2017:8158254.

Aloesin is an active constituent of the herb aloe vera and plays a crucial role in anti-inflammatory activity, ultraviolet protection, and antibacterium. We investigated the role and possible mechanisms of Aloesin in the cell growth and metastasis of ovarian cancer. It was found that Aloesin inhibited cell viability and cell clonality in a dose-dependent manner. It arrests the cell cycle at the S-phase and induced apoptosis in SKOV3 cells. In an in vivo experiment, it was observed that Aloesin inhibited tumor growth. Moreover, it inhibited migration and invasion of cancer in SKOV3 cells. Interestingly, members from the mitogen-activated protein kinase (MAPK) signaling family became less phosphorylated as the Aloesin dose increased. This suggests that Aloesin exerts its anticancer effect through the MAPK signaling pathway. Our data also highlights the possibility of using Aloesin as a novel therapeutic drug for ovarian cancer treatment.

Are Natural Ingredients Effective in the Management of Hyperpigmentation? A Systematic Review.[Pubmed:29552273]

J Clin Aesthet Dermatol. 2018 Feb;11(2):28-37. Epub 2018 Feb 1.

BACKGROUND: Hyperpigmentation disorders are commonly encountered in dermatology clinics. Botanical and natural ingredients have gained popularity as alternative depigmenting products. OBJECTIVE: We sought to review clinical studies evaluating the use of different natural products in treating hyperpigmentation so clinicians are better equipped to educate their patients. Specific ingredients reviewed include azelaic acid, Aloesin, mulberry, licorice extracts, lignin peroxidase, kojic acid, niacinamide, ellagic acid, arbutin, green tea, turmeric, soy, and ascorbic acid. METHODS: Systematic searches of PubMed and SCOPUS databases were performed in March 2016 using the various ingredient names, "melasma"and "hyperpigmentation." Two reviewers independently screened titles, leading to the selection of 30 clinical studies. RESULTS: Review of the literature revealed few clinical trials that evaluated the treatment of hyperpigmentation with natural ingredients. Despite the limited evidence-based research, several natural ingredients did show efficacy as depigmenting agents, including azelaic acid, soy, lignin peroxidase, ascorbic acid iontophoresis, arbutin, ellagic acid, licorice extracts, niacinamide, and mulberry. CONCLUSION: The aforementioned ingredients show promise as natural treatments for patients with hyperpigmentation disorders. These agents might also provide clinicians and researchers with a way to further characterize the pathogenesis of dyschromia. However, the paucity of clinical studies is certainly a limitation. Additionally, many of the in-vivo studies are limited by the short length of the trials, and questions remain about the long-term efficacy and safety of the ingredients used in these studies. Lastly, we suggest a standardized objective scoring system be implemented in any further comparative studies.

Melanogenesis Inhibitors: Strategies for Searching for and Evaluation of Active Compounds.[Pubmed:27356545]

Curr Med Chem. 2016;23(31):3548-3574.

Hyperpigmentation disorders constitute important medical and aesthetical conditions. Dark areas or dark spots on the skin result from inappropriate amount and/or deposition of skin pigments - melanins. Several depigmenting agents, such as kojic acid, arbutin, Aloesin, ellagic acid, resveratrol, azelaic acid, niacinamide, tretinoin, glycolic acid, lactic acid, and citric acid, have already been identified and are used in topical drugs or cosmetic formulations for the treatment of hyperpigmentations. However, these compounds are characterized by insufficient effectiveness and multiple adverse effects. As a result, there is still a need for searching for new active substances. The current paper summarizes strategies for searching for novel melanogenesis inhibitors. In the review, they are divided according to approach, into in silico, in vitro and in vivo experiments. In silico research includes computational studies with models of tyrosinase and di-copper complexes. The in vitro approach is based on tests using tyrosinase (a key enzyme in melanin biosynthesis), cell cultures, cell co-cultures, pigmented human skin equivalents or Streptomyces bikiniensis model. In vivo studies involve zebrafish, rodents or humans. Examples of protocols and laboratory procedures are presented, with a focus on utilization of various models for evaluation of mechanisms of action of tested compounds. The potential limitations of the methods are also discussed, together with future perspectives in the field of searching for melanogenesis inhibitors.

Tyrosinase inhibitory components from Aloe vera and their antiviral activity.[Pubmed:27778516]

J Enzyme Inhib Med Chem. 2017 Dec;32(1):78-83.

A new compound, 9-dihydroxyl-2'-O-(Z)-cinnamoyl-7-methoxy-Aloesin (1), and eight known compounds (2-9) were isolated from Aloe vera. Their structures were elucidated using 1D/2D nuclear magnetic resonance and mass spectra. Compound 9 exhibited reversible competitive inhibitory activity against the enzyme tyrosinase, with an IC50 value of 9.8 +/- 0.9 microM. A molecular simulation revealed that compound 9 interacts via hydrogen bonding with residues His244, Thr261, and Val283 of tyrosinase. Additionally, compounds 3 and 7 were shown by half-leaf assays to exhibit inhibitory activity towards Pepper mild mottle virus.
