Ascorbic acid 2-glucoside: An ascorbic acid pro-drug with longer-term antioxidant efficacy in skin. Int J Cosmet Sci 2021; 43:691-702. [PMID: 34679221 DOI: 10.1111/ics.12745] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 10/16/2021] [Accepted: 10/19/2021] [Indexed: 01/05/2023]
Abstract
OBJECTIVE Deleterious effects of pollutants and ultraviolet radiation on the skin can be attenuated using formulations containing antioxidants. However, these have disadvantages, including chemical instability, photodegradation, poor bioavailability or biological activity. Here, two commercial formulations were evaluated: one optimized to stabilize and deliver ascorbic acid (AA) at 15% and the other containing a glucoside form of AA, namely ascorbic acid 2-glucoside (AA2G), at 1.8% and at a physiological pH. We compared the skin delivery, antioxidative effects and chemical stability of AA2G with AA in their respective formulations. METHODS Skin delivery was measured using fresh viable human skin explants, and oxidative stress was measured using a human reconstructed epidermal (RHE) model according to levels of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase. RESULTS Ascorbic acid 2-glucoside was completely metabolized to AA by the skin before entering the receptor compartment. The skin contained parent and AA, indicating a reserve of AA2G was present for further metabolism. For AA2G and AA, maximum flux of AA-equivalents was at 12 h, with continued absorption over 24 h. The absolute amount in µg was higher in the skin after application of AA than after application of AA2G. This may suggest a greater antioxidative effect; however, according to all three measurements of oxidative stress, the protective effect of AA and AA2G was similar. Unlike AA, AA2G was chemically stable under storage conditions. CONCLUSION A lower concentration of AA2G is as effective as the active metabolite, AA, in terms of antioxidant effects. AA2G was chemically stable and can be applied at a lower concentration than AA, thus avoiding the need for an acidic formulation with a pH below 3.5.

Abstract
Stem cells from human exfoliated deciduous teeth (SHEDs) are considered a type of mesenchymal stem cells (MSCs) because of their unique origin from the neural crest. SHEDs can self-renewal and multi-lineage differentiation with the ability to differentiate into odontoblasts, osteoblast, chondrocytes, neuronal cells, hepatocytes, adipocytes, etc. They are emerging as an ideal source of MSCs because of their easy availability and extraordinary cell number. Ascorbic acid, or vitamin C, has many cell-based applications, such as bone regeneration, osteoblastic differentiation, or extracellular matrix production. It also impacts stem cell plasticity and the ability to sustain pluripotent activity. In this study, we evaluate the effects of ascorbic acid on stemness, paracrine secretion, and differentiation into osteoblast, chondrocytes, and adipocytes. SHEDs displayed enhanced multifaceted activity, which may have applications in regenerative therapy.

Abstract
Wound healing is a complex process which requires appropriate structural support for restoration of tissue continuity and function. Collagen can act as a template for cellular activities but poor physico-chemical properties necessitates the stabilization of collagen without impairing its structure and function. This study investigates the effect of magnesium ascorbyl phosphate (MAP) on collagen with reference to physico-chemical properties. Incorporation of MAP enhanced the rate of collagen fibrillation signifying increased interaction at reduced time interval. MAP did not induce any changes in the secondary structure of collagen while there was an increase in shear viscosity with increase in shear stress at different shear rate. MAP stabilized collagen film exhibited higher denaturation temperature and showed an increase in Young's Modulus when compared with that of collagen film. In vivo studies showed complete wound closure on day 16 in case of stabilized collagen film. Mechanical properties of healed skin revealed that MAP collagen film treated rat skin completely regained its properties similar to that of normal skin thereby making them a potential candidate for wound healing application.

Abstract
l-Ascorbic acid (ASA), vitamin C, is a ubiquitous carbohydrate-like compound that has an essential role in a number of cellular processes, such as collagen synthesis, cellular oxidation, and various hydroxylation reactions. ASA is a biomolecule of critical importance for protection of cellular components against oxidative damage caused by toxic free radicals and other reactive oxygen species (ROS) that are involved in the development of various types of chronic diseases. Vitamin C has a switchover role from being an antioxidant in physiological conditions to a prooxidant under pathologic conditions. Moreover, some l-ascorbic acid derivatives exhibit strong and selective antitumor and antiviral activity. This review emphasizes the advances on diverse and potent biological profiles of l-ascorbic acid and its derivatives, and their perspective in the development of new bioactive chemical entities in the future. The work is primarily addressed at antioxidant, anticancer, and antiviral potencies of l-ascorbic acid and compounds containing its butenolide structural motif.

Abstract
l-ascorbic acid 2-phosphate (Asc-2P) acts as an antioxidant and a stimulator of hepatocyte growth factor (HGF) production. Previously, we reported that depletion of growth factors such as fibroblast growth factor (FGF)-2, epidermal growth factor (EGF), FGF-4 and HGF during serial passage could induce autophagy, senescence and down-regulation of stemness (proliferation via FGF-2/-4 and differentiation via HGF). In this study, we investigated the proliferation and differentiation potential of BMSCs by FGF-2 and Asc-2P. Co-treatment with FGF-2 and Asc-2P induced optimal proliferation of BMSCs and increased the accumulation rate of BMSC numbers during a 2-month culture period. Moreover, differentiation potential was maintained by co-treatment with FGF-2 and Asc-2P via HGF expression. Adipogenic differentiation potential by FGF-2 and Asc-2P was dramatically suppressed by c-Met inhibitors (SU11274). These data suggest that co-treatment with FGF-2 and Asc-2P would be beneficial in obtaining BMSCs that possess "stemness" during long-term culture.

Abstract
This study aimed to develop a novel wound dressing composed of hyaluronic acid (HA) spongy sheet containing bioactive components. The wound dressing prepared by the freeze-drying method has a two-layered structure: an upper layer composed of cross-linked high-molecular-weight HA (HMW-HA) and a lower layer composed of low-molecular-weight HA (LMW-HA) containing arginine (Arg), magnesium ascorbyl phosphate (vitamin C derivative: VC), and epidermal growth factor (EGF) (referred to as EGF-dressing). A wound dressing containing only Arg and VC was prepared in a similar manner (referred to as EGF-free-dressing). The potential of each wound dressing was evaluated in animal tests using Sprague Dawley (SD) rats and diabetic mice. In the first experiment, each wound dressing was applied to a full-thickness skin defect in the abdominal region of SD rats. Wound conditions after 1 week and 2 weeks of treatment were evaluated based on macroscopic and histological appearance. A commercially available non-woven alginate wound dressing (Alg-dressing) was used in a control group. Both EGF-free-dressing and EGF-dressing decreased wound size and promoted granulation tissue formation associated with angiogenesis more effectively when compared with Alg-dressing. In particular, EGF-dressing promoted re-epithelialization. In the second experiment, each wound dressing was applied to a full-thickness skin defect in the dorsal region of diabetic mice. Wound conditions after 1 week and 2 weeks of treatment were evaluated based on macroscopic and histological appearance. A commercially available Alg-dressing was used in a control group. Both EGF-free-dressing and EGF-dressing decreased wound size and promoted granulation tissue formation associated with angiogenesis more effectively when compared with Alg-dressing. These findings indicate that EGF-free-dressing and EGF-dressing have the potential for more effective wound healing when compared with Alg-dressing. In particular, EGF-dressing has a higher potential for wound healing when compared with EGF-free-dressing.

Abstract
Mesenchymal stem cells (MSCs) have been shown to improve the outcome of acute renal injury models; but whether MSCs can delay renal failure in chronic kidney disease (CKD) remains unclear. In the present study, the were cultured in media containing various concentrations of basic fibroblast growth factor, epidermal growth factor and ascorbic acid 2-phosphate to investigate whether hepatocyte growth factor (HGF) secretion could be increased by the stimulation of these growth factors. Then, TGF-β1-treated renal interstitial fibroblast (NRK-49F), renal proximal tubular cells (NRK-52E) and podocytes were co-cultured with conditioned MSCs in the absence or presence of ascorbic acid 2-phosphate to quantify the protective effects of conditioned MSCs on renal cells. Moreover, male Sprague-Dawley rats were treated with 1 × 106 conditioned MSCs immediately after 5/6 nephrectomy and every other week through the tail vein for 14 weeks. It was found that basic fibroblast growth factor, epidermal growth factor and ascorbic acid 2-phosphate promoted HGF secretion in MSCs. Besides, conditioned MSCs were found to be protective against TGF-β1 induced epithelial-to-mesenchymal transition of NRK-52E and activation of NRK-49F cells. Furthermore, conditioned MSCs protected podocytes from TGF-β1-induced loss of synaptopodin, fibronectin induction, cell death and apoptosis. Rats transplanted with conditioned human MSCs had a significantly increase in creatinine clearance rate, decrease in glomerulosclerosis, interstitial fibrosis and increase in CD4+CD25+Foxp3+ regulatory T cells counts in splenocytes. Together, our studies indicated that conditioned MSCs preserve renal function by their anti-fibrotic and anti-inflammatory effects. Transplantation of conditioned MSCs may be useful in treating CKD.

Abstract
Mouse genetic studies reveal that ascorbic acid (AA) is essential for osteoblast (OB) differentiation and that osterix (Osx) was a key downstream target of AA action in OBs. To determine the molecular pathways for AA regulation of Osx expression, we evaluated if AA regulates Osx expression by regulating production and/or actions of local growth factors and extracellular matrix (ECM) proteins. Inhibition of actions of IGFs by inhibitory IGFBP-4, BMPs by noggin, and ECM-mediated integrin signaling by RGD did not block AA effects on Osx expression in OBs. Furthermore, blockade of components of MAPK signaling pathway had no effect on AA-induced Osx expression. Because AA is required for prolyl hydroxylase domain (PHD) activity and because PHD-induced prolyl-hydroxylation targets proteins to proteosomal degradation, we next tested if AA effect on Osx expression involves activation of PHD to hydroxylate and induce ubiquitin-proteosome-mediated degradation of transcriptional repressor(s) of Osx gene. Treatment of OBs with dimethyloxallyl glycine and ethyl 3, 4-dihydroxybenzoate, known inhibitors of PHD, completely blocked AA effect on Osx expression and OB differentiation. Knockdown of PHD2 expression by Lentivirus-mediated shRNA abolished AA-induced Osx induction and alkaline phosphatase activity. Furthermore, treatment of OBs with MG115, inhibitor of proteosomal degradation, completely blocked AA effects on Osx expression. Based on these data, we conclude that AA effect on Osx expression is mediated via a novel mechanism that involves PHD2 and proteosomal degradation of a yet to be identified transcriptional repressor that is independent of BMP, IGF-I, or integrin-mediated signaling in mouse OBs.

Abstract
Adipose-derived stem/stromal cells (ASCs) not only function as tissue-specific progenitor cells but also are multipotent and secrete angiogenic growth factors, such as hepatocyte growth factor (HGF), under certain circumstances. However, the biological role and regulatory mechanism of this secretion have not been well studied. We focused on the role of ASCs in the process of adipose tissue injury and repair and found that among injury-associated growth factors, fibroblast growth factor-2 (FGF-2) strongly promoted ASC proliferation and HGF secretion through a c-Jun N-terminal kinase (JNK) signaling pathway. In a mouse model of ischemia-reperfusion injury of adipose tissue, regenerative changes following necrotic and apoptotic changes were seen for 2 weeks. Acute release of FGF-2 by injured adipose tissue was followed by upregulation of HGF. During the adipose tissue remodeling process, adipose-derived 5-bromo-2-deoxyuridine-positive cells were shown to be ASCs (CD31-CD34+). Inhibition of JNK signaling inhibited the activation of ASCs and delayed the remodeling process. In addition, inhibition of FGF-2 or JNK signaling prevented postinjury upregulation of HGF and led to increased fibrogenesis in the injured adipose tissue. Increased fibrogenesis also followed the administration of a neutralizing antibody against HGF. FGF-2 released from injured tissue acts through a JNK signaling pathway to stimulate ASCs to proliferate and secrete HGF, contributing to the regeneration of adipose tissue and suppression of fibrogenesis after injury. This study revealed a functional role for ASCs in the response to injury and provides new insight into the therapeutic potential of ASCs.

Abstract
Adipose tissue serves as a source of adipokines and cytokines with both local and systemic actions in health and disease. In this study, we examine the hypothesis that multipotent human adipose-derived stem cells (ASCs), capable of differentiating along the adipocyte, chondrocyte, and osteoblast pathways, contribute to adipose tissue-derived cytokine secretion. Following exposure to basic fibroblast growth factor (bFGF) or epidermal growth factor (EGF), the ASCs significantly increase their secretion of hepatocyte growth factor (HGF), a cytokine implicated in hematopoiesis, vasculogenesis, and mammary epithelial duct formation. Ascorbic acid synergizes with these inductive factors, further increasing HGF levels. Following exposure to lipopolysaccharide, ASCs increase their secretion of both hematopoietic (granulocyte/monocyte, granulocyte, and macrophage colony stimulating factors, interleukin 7) and proinflammatory (interleukins 6, 8, and 11, tumor necrosis factor alpha) cytokines based on ELISA and RT-PCR. In co-cultures established with umbilical cord blood-derived CD34(+) cells, the ASCs support long-term hematopoiesis in vitro. Furthermore, in short-term 12-day co-cultures, the ASC maintain and expand the numbers of both myeloid and lymphoid progenitors. These observations are consistent with the functionality of the secreted cytokines and confirm recent reports by other laboratories concerning the hematopoietic supportive capability of ASCs. We conclude that the ASCs display cytokine secretory properties similar to those reported for bone marrow-derived mesenchymal stem cells (MSCs).

Abstract
Topical treatment of skin with all-trans-retinoic acid (ATRA), the major biologically active form of vitamin A, results in hyperproliferation of basal keratinocytes, leading to an accelerated turnover of epidermis cells and thickening of the epidermis, probably via induction of production of paracrine growth factors for keratinocytes in epidermal suprabasal keratinocytes and/or dermal fibroblasts. Since hepatocyte growth factor (HGF) is a factor mitogenic to epidermal keratinocytes secreted from dermal fibroblasts, the effect of ATRA on basal and induced HGF production in human dermal fibroblasts in culture was examined. ATRA alone did not induce HGF production, but it significantly enhanced HGF production induced by the cAMP-elevating agent cholera toxin or the membrane-permeable cAMP analog 8-bromo-cAMP. Cholera toxin-induced activation of cAMP responsive element (CRE)-binding protein (CREB) was enhanced by pretreating cells with ATRA for 24 h. In contrast, HGF production induced by epidermal growth factor (EGF) or phorbol 12-myristate 13-acetate (PMA) was potently inhibited by ATRA. These modulatory effects of ATRA were different from the effects of transforming growth factor-beta1 (TGF-beta) and dexamethasone, both of which inhibited HGF production induced by all of the four inducers. Up-regulation of HGF gene expression by cholera toxin and EGF was also enhanced and inhibited, respectively, by ATRA. Both 9-cis-retinoic acid (9-cis-RA) and 13-cis-retinoic acid (13-cis-RA), which are stereo-isomers of ATRA, showed a modulatory effect on HGF induction similar to that of ATRA. These results suggest that ATRA augments the induction of HGF production caused by increased intracellular cAMP.

Abstract
Hepatocyte growth factor (HGF) stimulates the proliferation of hepatocytes and biliary epithelial cells and protects hepatocytes from apoptosis induced by various stimuli. In view of HGF induction by interferons, substances used for the treatment of chronic hepatitis C, this study was conducted to determine whether ursodeoxycholic acid (UDCA), which is widely used for the treatment of cholestatic liver diseases, modulates HGF production. UDCA did not induce HGF production in human dermal fibroblasts, but it potently inhibited phorbol-12-myristate-13-acetate (PMA)- and cholera-toxin-induced HGF production without affecting cell viability. The inhibitory effects of UDCA were as potent as those of transforming growth factor-beta1 and dexamethasone. Up-regulations of HGF gene expression induced by PMA and cholera toxin were also inhibited by UDCA. Moreover, UDCA dose-dependently inhibited high constitutive HGF production by MRC-5 cells without decreasing cell viability. Deoxycholate, chenodeoxycholate, taurochenodeoxycholate and glycochenodeoxycholate also inhibited cholera-toxin-induced HGF production at non-cytotoxic doses. UDCA, however, had no apparent effect on PMA-induced phosphorylation of mitogen-activated protein kinase, which is crucial for HGF induction by PMA. These results indicate that non-cytotoxic doses of UDCA inhibited constitutive and induced HGF production and suggest that UDCA supplemented with HGF or HGF inducers could have a more potential therapeutic effect.

Abstract
Hepatocyte growth factor (HGF) is one of the vital factors for liver regeneration. HGF production is induced by the activation of protein kinase A and protein kinase C-mediated pathways, interleukin (IL)-1, tumor necrosis factor (TNF)-alpha, and epidermal growth factor (EGF) in mesenchymal cells. We here report that IL-1 and TNF-alpha, hitherto regarded as HGF inducers, potently inhibited HGF production stimulated by other HGF inducers. IL-1alpha, IL-1beta, and TNF-alpha alone had minimal stimulating effects on HGF production in human dermal fibroblasts, but they strongly inhibited production of HGF induced by cholera toxin, 8-bromo-cAMP, EGF, and phorbol 12-myristate 13-acetate (PMA). Moreover, although the high level of HGF production in MRC-5 cells was enhanced by PMA and less markedly by IL-1beta, HGF production in MRC-5 cells treated with PMA plus IL-1beta was less than that in the cells treated with PMA alone. In the presence of interferon (IFN)-gamma, however, cholera toxin- and 8-bromo-cAMP-induced HGF production was not inhibited by IL-1beta. Pretreatment of cells with IL-1beta suppressed the phosphorylation of cAMP-responsive element-binding protein induced by cholera toxin but not that induced by 8-bromo-cAMP. Taken together, our results indicate that IL-1 inhibited HGF production stimulated by various inducers, including protein kinase A-activating agents, and that IFN-gamma overcame this inhibition of induction of HGF production.

Abstract
Staurosporine is one of the most potent and well known inhibitors of protein kinases, and it is often used to study the involvement of protein kinases in signal transduction pathways. We now report that staurosporine can induce the production of hepatocyte growth factor (HGF) independently of protein kinase inhibition. Staurosporine markedly stimulated the production of HGF in various cell types, including human skin fibroblasts. Its effect was accompanied by up-regulation of HGF gene expression. The inhibition of protein kinases appears not to be involved in staurosporine-induced HGF production, because other protein kinase inhibitors, K-252a, H-7, GF 109203X and genistein, had no HGF-inducing activity. UCN-01, 7-hydroxystaurosporine, which differs from staurosporine only in its aglycone moiety, also showed HGF-inducing activity, and inactive K-252a differs from staurosporine only in its sugar moiety. These results indicate that the sugar moiety, a six-atom ring structure, is important in the HGF-inducing activity of staurosporine. Experiments were then carried out to determine whether the characteristics of staurosporine-induced HGF production have similarities to those of HGF production stimulated by other HGF inducers. The effect of staurosporine like that of 8-bromo-cAMP and that of cholera toxin was marked in human skin fibroblasts from all four different sources, whereas the effects of epidermal growth factor and phorbol 12-myristate 13-acetate were variable depending on cells. The net increase in HGF production induced by staurosporine was not reduced in protein kinase C-depleted human skin fibroblasts. Moreover, synergistic induction of HGF was detected between staurosporine and interferon-gamma as well as between 8-bromo-cAMP and interferon-gamma. Staurosporine, however, did not increase intracellular cAMP levels in human skin fibroblasts. These results indicate that staurosporine induced HGF in different cell types via a signaling pathway similar to the cAMP-mediated pathway without increasing cAMP levels.

Abstract
Hepatocyte growth factor (HGF) was purified as a potent mitogen for rat hepatocytes in primary culture and is believed to be the most physiological hepatotrophic factor that triggers liver regeneration. HGF is one of the largest disulfide-linked cytokines, consisting of a 60-kDa heavy chain and a 35-kDa light chain. Human HGF is synthesized as a single polypeptide chain precursor of 728 amino acid residues that has an appreciable homology with plasminogen, and it is processed proteolytically to release an N-terminal signal peptide of 31 amino acids and to generate an active heterodimer after secretion. The novel serine protease HGF activator and urokinase-type plasminogen activator (u-PA) are responsible for the latter extracellular processing. HGF stimulates the proliferation of rat hepatocytes in primary culture at concentrations as low as 10 pM. It also stimulates the growth of various epithelial cells, endothelial cells, and some kinds of mesenchymal cells. HGF inhibits the proliferation of several tumor cell lines and induces apoptosis of some of them. It also has motogenic, morphogenic, anti-apoptotic, angiogenic, and immunoregulatory activities. The receptor of HGF is the product of c-met proto-oncogene with tyrosine kinase activity that mediates the transduction of multiple biological signals of HGF. During liver regeneration, HGF gene expression in the liver, spleen, and lung and HGF levels in the blood and liver increase prior to the induction of liver DNA synthesis. Liver regeneration is markedly inhibited by continuous administration of a neutralizing anti-HGF antibody. HGF production in cultured cells is induced by PKC-activating agents, cAMP-elevating agents, PKA-activating agents, growth factors, and inflammatory cytokines; and it is inhibited by TGF-beta, glucocorticoids, 1,25-dihydroxyvitamin D3, and retinoic acid. There are many reports on potential application of HGF as a therapeutic agent for organ diseases that are difficult to cure such as liver cirrhosis, chronic renal failure, pulmonary fibrosis, myocardial infarction, and arteriosclerosis obliterans utilizing its potent growth-stimulating activity for a wide variety of cells. ELISA kits for assays of serum and plasma HGF levels are clinically used to prognosticate the development of fulminant hepatic failure.

Abstract
In this study, we examined whether the production of hepatocyte growth factor (HGF) in fibroblasts is regulated by protein phosphatase(s). Inhibitors of the enzymes okadaic acid and calyculin A were used for this purpose. Both inhibitors markedly stimulated HGF production in human skin fibroblasts in a dose-dependent manner. The effects of okadaic acid and calyculin A were maximal at 25-37.5 and 1.25 nM, respectively. Highly active HGF production in MRC-5 human embryonic lung fibroblasts was also promoted by both inhibitors. The effect of okadaic acid was accompanied by an up-regulation of HGF gene expression. The stimulating effect of okadaic acid on HGF production was synergistic with that of phorbol 12-myristate 13-acetate (PMA) and epidermal growth factor (EGF), whereas it was additive to the effect of cholera toxin. The protein kinase C (PKC) inhibitor GF 109203X inhibited the effect of PMA, but not of okadaic acid and EGF. The effect of okadaic acid as well as EGF was not inhibited, but rather enhanced in human skin fibroblasts pretreated for 24 hr with a high dose of PMA to deplete PKC, as compared with its effect in untreated cells. PD 98059, an inhibitor of mitogen-activated protein (MAP) kinase kinase, suppressed the effects of okadaic acid and EGF, but not those of cholera toxin and 8-bromo-adenosine 3',5'-cyclic monophosphate (cAMP). These results suggest that HGF production in human skin fibroblasts is down-regulated by protein phosphatase(s) and that HGF production stimulated by okadaic acid is, at least in part, dependent on the activation of the MAP kinase cascade.
