Streptomyces-Derived Metabolites with Potential Photoprotective Properties-A Systematic Literature Review and Meta-Analysis on the Reported Chemodiversity. Molecules 2020; 25:E3221. [PMID: 32679651 PMCID: PMC7397340 DOI: 10.3390/molecules25143221] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 07/01/2020] [Accepted: 07/07/2020] [Indexed: 02/07/2023] Open
Abstract
Sun overexposure is associated with the development of diseases that primarily affect the skin, which can lead to skin cancer. Among the main measures of photoprotection is the use of sunscreens. However, there is currently concern about the reported harmful effects to both humans and the environment due to several of the sunscreen ingredients available on the market. For this reason, the search for and development of new agents with photoprotective properties is required. In searching for these metabolites, researchers have turned their attention to microbial sources, especially the microbiota in unusual hostile environments. Among the diverse microorganisms available in nature, Actinobacteria and specifically Streptomyces, have been shown to be a source of metabolites with various biological activities of interest, such as antimicrobial, antitumor and immunomodulator activities. Herein, we present the results of a systematic review of the literature in which Streptomyces isolates were studied as a source of compounds with photoprotective properties. A meta-analysis of the structure-property and structure-activity relationships of those metabolites identified in the qualitative analysis phase was also carried out. These findings indicate that Streptomyces are a source of metabolites with potential applications in the development of new, safe and more eco-friendly sunscreens.

Abstract
Immunoisolation of pancreatic islets is a technology in which islets are encapsulated in semipermeable but immunoprotective polymeric membranes. The technology allows for successful transplantation of insulin-producing cells in the absence of immunosuppression. Different approaches of immunoisolation are currently under development. These approaches involve intravascular devices that are connected to the bloodstream and extravascular devices that can be distinguished in micro- and macrocapsules and are usually implanted in the peritoneal cavity or under the skin. The technology has been subject of intense fundamental research in the past decade. It has co-evolved with novel replenishable cell sources for cure of diseases such as Type 1 Diabetes Mellitus that need to be protected for the host immune system. Although the devices have shown significant success in animal models and even in human safety studies most technologies still suffer from undesired tissue responses in the host. Here we review the past and current approaches to modulate and reduce tissue responses against extravascular cell-containing micro- and macrocapsules with a focus on rational choices for polymer (combinations). Choices for polymers but also choices for crosslinking agents that induce more stable and biocompatible capsules are discussed. Combining beneficial properties of molecules in diblock polymers or application of these molecules or other anti-biofouling molecules have been reviewed. Emerging are also the principles of polymer brushes that prevent protein and cell-adhesion. Recently also immunomodulating biomaterials that bind to specific immune receptors have entered the field. Several natural and synthetic polymers and even combinations of these polymers have demonstrated significant improvement in outcomes of encapsulated grafts. Adequate polymeric surface properties have been shown to be essential but how the surface should be composed to avoid host responses remains to be identified. Current insight is that optimal biocompatible devices can be created which raises optimism that immunoisolating devices can be created that allows for long term survival of encapsulated replenishable insulin-producing cell sources for treatment of Type 1 Diabetes Mellitus.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Almost all part of the plant Aegle marmelos (Bael tree) has been used in the traditional medicine systems of Asian countries to treat various diseases over many centuries. The water extract of the dried flowers of Aegle marmelos is a commonly used beverage among Sri Lankan population in rural areas. Although extensive investigations done on many parts of the plant there are no experimental data available on the extracts of flowers. Anti-inflammatory effect of the water extract of dried flowers of Aegle marmelos (WEAM) was evaluated in the present study. MATERIALS AND METHODS The anti-inflammatory effect of the WEAM was evaluated by inhibition of the rat paw oedema, induced by carrageenan. The mechanism of the anti-inflammatory effect was assessed by the inhibition of production of nitric oxide (NO) by rat peritoneal cells, infiltration of rat peritoneal cells, anti-histamine effect, membrane stabilization activity, the antioxidant capacity and inhibition of lipid peroxidation by the WEAM. RESULTS The maximum percentage inhibition of paw oedema was exhibited by the dose of 200 mg/kg at 2 h. The WEAM showed a significant increment of rat peritoneal cell infiltration, inhibition of NO production by rat peritoneal cells and inhibition of wheal formation on the skin of the rat after injection of histamine. The WEAM protected the erythrocyte membrane from heat-induced lysis in a dose-dependent manner and showed a significant anti-oxidant effect and lipid peroxidation inhibition activity. CONCLUSION The WEAM possesses significant anti-inflammatory effect by multiple mechanisms in Wistar rats.

Abstract
To elucidate the anti-inflammatory action of nicotine-induced corticosterone elevation on the passive skin Arthus reaction (PSAR), we investigated the inflammatory process in the PSAR. The polymorphonuclear leukocyte (PMNs) infiltration was observed just before as well as after elicitation by measuring extractable myeloperoxidase. The plasma exudation was significantly inhibited by anti-rat tumor necrosis factor (TNF)-alpha antibody (5 microg/site, i.d.) at the time of sensitization or by superoxide dismutase (52500 units/kg, i.p.) 1 h before elicitation or N(G)-nitro-L-arginine-methyl ester (100 mg/kg, i.v.) just at elicitation. Pretreatment with a single injection of nicotine (0.8 mg/kg, i.p.) 30 min before elicitation suppressed the plasma exudation but not the PMNs infiltration. This nicotine-induced decreasing effect was abolished in animals supplemented with L-arginine (300 mg/kg, i.v.) just at elicitation. The production of nitric oxide (NO) in peritoneal PMNs derived from an animal injected peritoneally with oyster glycogen was significantly suppressed by pretreatment with nicotine (0.8 mg/kg, i.v.) 30 min prior to harvesting. This inhibitory action of nicotine was abolished in animals pretreated with mifepristone (30 mg/kg, s.c.), a glucocorticoid receptor antagonist. These findings indicate that a single systematic administration of nicotine may attenuate the plasma exudation in the PSAR by suppressing the production of NO in the PMNs primed with TNF-alpha via nicotine-induced endogenous glucocorticoid.

Abstract
To evaluate the relationship between nicotine and immunological inflammation, we investigated the effects of nicotine on plasma extravasation of the passive skin Arthus reaction, elicited 4 hr after sensitizing skin with antiserum, and serum corticosterone levels in rats. Pretreatment with a single subcutaneous injection of nicotine (0.4 or 0.8 mg/kg) 30 or 60 min. before antigen challenge attenuated the passive skin Arthus reaction immunological inflammation. Serum corticosterone levels were dose-dependently increased 30 and 60 min. after nicotine administration. Both markers co-varied with a similar dose-response and time course after the nicotine-treatment. In addition, we also examined these nicotine-induced responses after bilateral lesions of the hypothalamic paraventricular nucleus; both the nicotine-induced suppression of immunological inflammation and the increased serum corticosterone levels were attenuated in bilateral paraventricular nucleus-lesioned animals. Moreover, the immunological inflammatory decreasing effects of a single subcutaneous injection of nicotine (0.4 mg/kg) were antagonized by intraperitoneal preinjection with mecamylamine (1.0 mg/kg; blocking the brain nicotinic acetylcholine receptors) as well as by subcutaneous preinjection with mifepristone (30 mg/kg; a glucocorticoid receptor antagonist) but not by intraperitoneal preinjection with hexamethonium (2.0 mg/kg; a peripheral nicotinic acetylcholine receptors antagonist). Finally, intraperitoneal preinjection with cycloheximide (2 mg/kg), a protein synthesis inhibitor, abolished both the inhibitory effect of nicotine (0.4 mg/kg) on the dye leakage and the elevation of blood corticosterone levels. These findings indicate that the nicotine-induced decreasing effect on immunological inflammatory response may be related to serum corticosterone levels elevated by an activation of the paraventricular nucleus through the brain nicotinic acetylcholine receptors.

Abstract
The studies were carried out to elucidate the effect of a novel cyclic peptide, SEK-1005 (C(45)H(70)N(8)O(13)), on wound healing. SEK-1005 (4-10 microg/wound) applied topically significantly accelerated the healing of a full-thickness wound on the dorsal skin of a rat. In a healing-impaired mouse, the peptide (2-10 microg/wound) had more potent activity, exerting an effect comparable to that of basic fibroblast growth factor (FGF). However, SEK-1005 (0.1-100 ng/ml) scarcely promoted the proliferation of cultured fibroblasts (NIH3T3 cells) while basic FGF (0.2-5 ng/ml) showed marked mitogenic activity. SEK-1005 (2-10 microg/wound) significantly increased the topical production of transforming growth factor (TGF)-beta1, a cytokine that is known to accelerate wound healing. This activity was closely correlated with the wound-repairing effect. From the above, SEK-1005 can be considered as a new type of wound healing agent with potent TGF-beta1-inducing activity.
