Membrane Interactivity of Capsaicin Antagonized by Capsazepine. Int J Mol Sci 2022; 23:ijms23073971. [PMID: 35409329 PMCID: PMC8999564 DOI: 10.3390/ijms23073971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 03/31/2022] [Accepted: 03/31/2022] [Indexed: 11/16/2022] Open
Abstract
Although the pharmacological activity of capsaicin has been explained by its specific binding to transient receptor potential vanilloid type 1, the amphiphilic structure of capsaicin may enable it to act on lipid bilayers. From a mechanistic point of view, we investigated whether capsaicin and its antagonist capsazepine interact with biomimetic membranes, and how capsazepine influences the membrane effect of capsaicin. Liposomal phospholipid membranes and neuro-mimetic membranes were prepared with 1,2-dipalmitoylphosphatidylcholine and with 1-palmitoyl-2-oleoylphosphatidylcholine and sphingomyelin plus cholesterol, respectively. These membrane preparations were subjected to reactions with capsaicin and capsazepine at 0.5–250 μM, followed by measuring fluorescence polarization to determine the membrane interactivity to modify the fluidity of membranes. Both compounds acted on 1,2-dipalmitoylphosphatidylcholine bilayers and changed membrane fluidity. Capsaicin concentration-dependently interacted with neuro-mimetic membranes to increase their fluidity at low micromolar concentrations, whereas capsazepine inversely decreased the membrane fluidity. When used in combination, capsazepine inhibited the effect of capsaicin on neuro-mimetic membranes. In addition to the direct action on transmembrane ion channels, capsaicin and capsazepine share membrane interactivity, but capsazepine is likely to competitively antagonize capsaicin’s interaction with neuro-mimetic membranes at pharmacokinetically-relevant concentrations. The structure-specific membrane interactivity may be partly responsible for the analgesic effect of capsaicin.

Abstract
Heat Shock Protein 90 (HSP90) is a fertility-associated protein, the expression of which positively correlates with sperm quality in many species. Geranylgeranylacetone (GGA) is reported to induce expression of HSP90. The present study aimed to investigate whether GGA induced expression of HSP90 in Acipenser sinensis sperm to exert a cryoprotective effect. Sperm from five male A. sinensis was combined with extender containing 20 mmol/L tris pH = 8.1, 10% v/v methanol, 2-5 mmol/L KCl, 15 mmol/L lactose, and 15 mmol/L trehalose, with GGA at 0, 14, 67, 135, 673, 1346, or 6731 μmol/L. After cryopreservation and thawing, the percentage of motile spermatozoa, spermatozoon curvilinear velocity (VCL), straight-line velocity (VSL), average path velocity (VAP), acrosome integrity, and membrane integrity, as well as fertility were evaluated. Sperm quality increased with the increase of GGA to 673 μmol/L, but decreased at higher concentrations. Expression levels of HSP90α were detected by Western blot in sperm frozen with GGA at 673 μmol/L (highest obtained sperm quality), 6731 μmol/L (highest GGA concentration), and a control without GGA. The expression of HSP90α increased with the increase in GGA, with lowest expression observed in the control. GGA was found to induce increase of HSP90α, and this increase was associated with higher quality cryopreserved sperm at concentrations ≤673 μmol/L. This research suggests a viable technique to increase the quality of cryopreserved A. sinensis sperm by adding GGA to induce expression of HSP90α.

Discrimination of Stereoisomers by Their Enantioselective Interactions with Chiral Cholesterol-Containing Membranes. Molecules 2017; 23:molecules23010049. [PMID: 29295605 PMCID: PMC5943951 DOI: 10.3390/molecules23010049] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Revised: 12/22/2017] [Accepted: 12/22/2017] [Indexed: 12/02/2022] Open
Abstract
Discrimination between enantiomers is an important subject in medicinal and biological chemistry because they exhibit markedly different bioactivity and toxicity. Although stereoisomers should vary in the mechanistic interactions with chiral targets, their discrimination associated with the mode of action on membrane lipids is scarce. The aim of this study is to reveal whether enantiomers selectively act on chiral lipid membranes. Different classes of stereoisomers were subjected at 5–200 μM to reactions with biomimetic phospholipid membranes containing ~40 mol % cholesterol to endow the lipid bilayers with chirality and their membrane interactions were comparatively evaluated by measuring fluorescence polarization. All of the tested compounds interacted with cholesterol-containing membranes to modify their physicochemical property with different potencies between enantiomers, correlating to those of their experimental and clinical effects. The rank order of membrane interactivity was reversed by changing cholesterol to C3-epimeric α-cholesterol. The same selectivity was also obtained from membranes prepared with 5α-cholestan-3β-ol and 5β-cholestan-3α-ol diastereomers. The opposite configuration allows molecules to interact with chiral sterol-containing membranes enantioselectively, and the specific β configuration of cholesterol’s 3-hydroxyl group is responsible for such selectivity. The enantioselective membrane interaction has medicinal implications for the characterization of the stereostructures with higher bioactivity and lower toxicity.

Abstract
The classic heat shock (stress) response (HSR) was originally attributed to protein denaturation. However, heat shock protein (Hsp) induction occurs in many circumstances where no protein denaturation is observed. Recently considerable evidence has been accumulated to the favor of the "Membrane Sensor Hypothesis" which predicts that the level of Hsps can be changed as a result of alterations to the plasma membrane. This is especially pertinent to mild heat shock, such as occurs in fever. In this condition the sensitivity of many transient receptor potential (TRP) channels is particularly notable. Small temperature stresses can modulate TRP gating significantly and this is influenced by lipids. In addition, stress hormones often modify plasma membrane structure and function and thus initiate a cascade of events, which may affect HSR. The major transactivator heat shock factor-1 integrates the signals originating from the plasma membrane and orchestrates the expression of individual heat shock genes. We describe how these observations can be tested at the molecular level, for example, with the use of membrane perturbers and through computational calculations. An important fact which now starts to be addressed is that membranes are not homogeneous nor do all cells react identically. Lipidomics and cell profiling are beginning to address the above two points. Finally, we observe that a deregulated HSR is found in a large number of important diseases where more detailed knowledge of the molecular mechanisms involved may offer timely opportunities for clinical interventions and new, innovative drug treatments. This article is part of a Special Issue entitled: Membrane Structure and Function: Relevance in the Cell's Physiology, Pathology and Therapy.

Characteristic interactivity of landiolol, an ultra-short-acting highly selective β1-blocker, with biomimetic membranes: Comparisons with β1-selective esmolol and non-selective propranolol and alprenolol. Front Pharmacol 2013; 4:150.

Abstract
Although β1-blockers have been perioperatively used to reduce the cardiac disorders associated with general anesthesia, little is known about the mechanistic characteristics of ultra-short-acting highly selective β1-blocker landiolol. We studied its membrane-interacting property in comparison with other selective and non-selective β1-blockers. Biomimetic membranes prepared with phospholipids and cholesterol of varying compositions were treated with β1-selective landiolol and esmolol and non-selective propranolol and alprenolol at 0.5-200 μM. The membrane interactivity and the antioxidant activity were determined by measuring fluorescence polarization and by peroxidizing membrane lipids with peroxynitrite, respectively. Non-selective β1-blockers, but not selective ones, intensively acted on 1,2-dipalmitoylphosphatidylcholine (DPPC) liposomal membranes and cardiomyocyte-mimetic membranes to increase the membrane fluidity. Landiolol and its inactive metabolite distinctively decreased the fluidity of DPPC liposomal membranes, suggesting that a membrane-rigidifying effect is attributed to the morpholine moiety in landiolol structure but unlikely to clinically contribute to the β1-blocking effect of landiolol. Propranolol and alprenolol interacted with lipid raft model membranes, whereas neither landiolol nor esmolol. All drugs fluidized mitochondria-mimetic membranes and inhibited the membrane lipid peroxidation with the potency correlating to their membrane interactivity. Landiolol is characterized as a drug devoid of the interactivity with membrane lipid rafts relating to β2-adrenergic receptor blockade. The differentiation between β1-blocking selectivity and non-selectivity is compatible with that between membrane non-interactivity and interactivity. The mitochondrial membrane fluidization by landiolol independent of blocking β1-adrenergic receptors is responsible for the antioxidant cardioprotection common to non-selective and selective β1-blockers.

Abstract
Amyloid-β peptide (Aβ) plays an important role in the pathogenesis of Alzheimer’s disease (AD). Aβ is generated by the secretase-mediated proteolysis of β-amyloid precursor protein (APP), and cleared by enzyme-mediated degradation and phagocytosis. Transforming growth factor (TGF)-β1 stimulates this phagocytosis. We recently reported that the APP23 mouse model for AD showed fewer AD-related phenotypes when these animals were crossed with transgenic mice expressing heat shock protein (HSP) 70. We here examined the effect of geranylgeranylacetone, an inducer of HSP70 expression, on the AD-related phenotypes. Repeated oral administration of geranylgeranylacetone to APP23 mice for 9 months not only improved cognitive function but also decreased levels of Aβ, Aβ plaque deposition and synaptic loss. The treatment also up-regulated the expression of an Aβ-degrading enzyme and TGF-β1 but did not affect the maturation of APP and secretase activities. These outcomes were similar to those observed in APP23 mice genetically modified to overexpress HSP70. Although the repeated oral administration of geranylgeranylacetone did not increase the level of HSP70 in the brain, a single oral administration of geranylgeranylacetone significantly increased the level of HSP70 when Aβ was concomitantly injected directly into the hippocampus. Since geranylgeranylacetone has already been approved for use as an anti-ulcer drug and its safety in humans has been confirmed, we propose that this drug be considered as a candidate drug for the prevention of AD.

Abstract
AIM: To compare the therapeutic efficacy and safety of teprenone combined with short- versus long-term use of omeprazole in the prevention of re-bleeding after endoscopic hemostasis for NSAIDs-related ulcers.
METHODS: Patients with NSAIDs-related ulcers who underwent Monteggia liquid spraying for bleeding were randomly divided into four groups: a teprenone group (n = 28), an omeprazole group (n = 33), a short-term combination group (n = 31), and a long-term combination group (n = 35). The incidences of re-bleeding and adverse reactions occurring during the periods of 0-13, 14-26, 0-26 and 27-52 wk were compared among the four groups.
RESULTS: The rate of re-bleeding occurring between 0 and 13 wk was significantly higher in the teprenone group than in the other groups (all P < 0.05), and the differences were not statistically significant between the other three groups (all P > 0.05). During the periods between 14 and 26 weeks and between 27 and 52 wk, there were no statistically significant differences in the rates of re-bleeding between the four groups (all P > 0.05). The incidences of adverse reactions showed no significant differences between the four groups during the period of the first 26 weeks (all P > 0.05) or between the omeprazole group and long-term combination group during the period between 27 and 52 wk (P > 0.05), but were significantly higher in the omeprazole group and long-term combination group than in the short-term combination group (both P < 0.05).
CONCLUSION: Teprenone in combination with short-term use of omeprazole has comparable efficacy to long-term use of omeprazole but is associated with significantly less adverse reactions in preventing the occurrence of re-bleeding after NSAIDs-related ulcers.

Abstract
Bisphosphonates such as alendronate and risedronate are commonly used for the treatment of postmenopausal osteoporosis. They have the gastrointestinal adverse effects such as erosions and ulcers in stomach and small intestine. However, the detailed biological mechanism remains to be elucidated. Since alendronate is suggested to increase the risk of non-steroidal anti-inflammatory drug-related gastropathy, we hypothesized that bisphosphonates and non-steroidal anti-inflammatory drugs have the same pathophysiological mechanisms in gastrointestinal mucosa: Bisphosphonates may induce cellular lipid peroxidation by inducing the production of mitochondrial superoxide. We also hypothesized that geranylgeranylacetone, an antiulcer drug, may prevent lipid peroxidation by reducing superoxide production. We treated gastric RGM1 cells and small intestinal IEC6 cells with alendronate or risedronate, and examined cellular injury, lipid peroxidation and superoxide production with specific fluorescent dyes, and underwent electron paramagnetic resonance spectroscopy to detect the production of superoxide in vitro. The results indicated that bisphosphonates indeed induced cellular injury, cellular lipid peroxidation, and superoxide production. We also demonstrated that the pretreatment of geranylgeranylacetone decreased superoxide production and prevented cellular lipid peroxidation. These results suggested that bisphosphonates, like non-steroidal anti-inflammatory drugs, induce lipid peroxidation by producing mitochondrial superoxide, which was prevented by geranylgeranylacetone.

Abstract
It is important in treatment of gastric ulcers to not only prevent further ulcer formation but also enhance ulcer healing. When cells are exposed to gastric irritants, expression of heat shock proteins (HSPs) is induced, making the cells resistant to the irritants. We recently reported direct evidence that HSPs, especially HSP70, are preventive against irritant-induced gastric ulcer formation. Gastric ulcer healing is a process involving cell proliferation and migration at the gastric ulcer margin and angiogenesis in granulation tissue. In this study, we have examined the role of HSP70 in gastric ulcer healing. Gastric ulcers were produced by focal and serosal application of acetic acid. Expression of HSP70 was induced in both the gastric ulcer margin and granulation tissue. Compared with wild-type mice, gastric ulcer healing was accelerated in transgenic mice expressing HSP70, and both cell proliferation at the gastric ulcer margin and angiogenesis in granulation tissue were enhanced. Oral administration of geranylgeranylacetone, an inducer of HSPs, to wild-type mice, either prior to or after ulcer formation, not only induced expression of HSP70 in the stomach but also accelerated gastric ulcer healing. On the other hand, oral administration of purified recombinant HSP70 prior to the ulcer formation, but not after formation, stimulated gastric ulcer healing. This study provides the first evidence that HSP70 accelerates gastric ulcer healing. The results also suggest that both the HSP70 produced prior to ulcer formation and released from damaged cells, and the HSP70 produced after ulcer formation are involved in this accelerated healing process.

Idiopathic pulmonary fibrosis (IPF) involves infiltration of leucocytes, pulmonary injury, fibrosis and resulting pulmonary dysfunction. Myofibroblasts and transforming growth factor (TGF)-beta1 have been suggested to play a major role in the pathology and the myofibroblasts are derived from both lung epithelial cells through epithelial-mesenchymal transition (EMT) and activation of lung fibroblasts. Heat shock protein 70 (HSP70) confers protection against various stressors and has the anti-inflammatory activity. In this study, we examined the effect of expression of HSP70 on bleomycin-induced pulmonary fibrosis in mice, a tentative animal model of IPF. Bleomycin-induced pulmonary injury and inflammatory response were ameliorated in transgenic mice overexpressing HSP70 compared to wild-type mice, even though bleomycin-induced pulmonary fibrosis and dysfunction were also suppressed in the transgenic mice. The production of TGF-beta1 and expression of pro-inflammatory cytokines was lower in cells from the transgenic mice than wild-type mice after the administration of bleomycin. In vitro, the suppression of HSP70 expression stimulated TGF-beta1-induced EMT-like phenotypes of epithelial cells but did not affect the TGF-beta1-dependent activation of fibroblasts. Orally administered geranylgeranylacetone (GGA), a clinically used drug with HSP-inducing activity, conferred protection against bleomycin-induced pulmonary injury, as well as against the inflammatory response, fibrosis and dysfunction. These results suggest that HSP70 plays a protective role against bleomycin-induced pulmonary injury, inflammation, fibrosis and dysfunction through cytoprotective effects and by inhibiting the production of TGF-beta1, TGF-beta1-dependent EMT of epithelial cells and expression of pro-inflammatory cytokines. Results also suggest that HSP70-inducing drugs, such as GGA, could be beneficial in the prophylaxis of IPF.

Abstract
PURPOSE It is well known that heat shock proteins (HSPs) are induced by various stressors in order to confer protection against such stressors. Since stressor-induced tissue damage is involved in various diseases, especially gastrointestinal diseases, it has been thought that HSP-inducers are therapeutically beneficial for these diseases. Indirect lines of evidence suggest that HSPs provide a major protective mechanism against irritant-induced gastric lesions. However, no direct evidence exists to support this notion. On the other hand, inflammatory bowel disease (IBD) involves infiltration of leukocytes into intestinal tissue, resulting in intestinal damage. Pro-inflammatory cytokines and cell adhesion molecules (CAMs) play important roles in this infiltration of leukocytes. The roles of heat shock factor 1 (HSF1, a transcription factor for hsp genes) and heat shock proteins (HSPs) in development of IBD are unclear. In this paper, we reviewed our recent work on the role of HSPs in pathogenesis of gastric lesions and IBD by use of HSF1-null mice and transgenic mice expressing Hsp70. CONCLUSION This study provides the first genetic evidence that HSF1 and Hsp70 play a role in protecting against both irritant-induced gastric lesions and IBD-related colitis. The aggravation of irritant-induced gastric lesions in HSF1-null mice is due to their inability to up-regulate Hsp70, leading to apoptosis. On the other hand, this protective role of Hsp70 against colitis seems to involve various mechanisms, such as suppression of expression of pro-inflammatory cytokines and CAMs, and cell death.

Abstract
A major clinical problem encountered with the use of non-steroidal anti-inflammatory drugs (NSAIDs) is gastrointestinal complications. We have previously suggested that both decreases in prostaglandin E(2) (PGE(2)) levels and mucosal apoptosis are involved in the development of NSAID-produced gastric lesions and that this apoptosis is mediated by an increase in the intracellular Ca(2+) concentration and the resulting endoplasmic reticulum (ER) stress response and mitochondrial dysfunction. Celecoxib and rebamipide are being used clinically as a safer NSAID and an anti-ulcer drug, respectively. In this study, we have examined the effect of rebamipide on celecoxib-induced production of gastric lesions. In mice pre-administered with a low dose of indomethacin, orally administered rebamipide suppressed celecoxib-induced mucosal apoptosis and lesion production but did not decrease in PGE(2) levels in the stomach. Rebamipide also suppressed celecoxib-induced increases in intracellular Ca(2+) concentration, the ER stress response, mitochondrial dysfunction and apoptosis in vitro. We also found that rebamipide suppresses the increases in intracellular Ca(2+) concentration induced by an activator of voltage-dependent L-type Ca(2+) channels and that another blocker of this channel suppresses celecoxib-induced increases in intracellular Ca(2+) concentration. These results suggest that celecoxib activates voltage-dependent L-type Ca(2+) channels and that rebamipide blocks this activation, resulting in suppression of celecoxib-induced apoptosis. We believe that this novel activity of rebamipide may play an important role in the protection of gastric mucosa against the formation of celecoxib-induced lesions.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed drugs worldwide, which attests to their efficacy as analgesic, antipyretic and anti-inflammatory agents as well as anticancer drugs. However, NSAID use also carries a risk of major gastroduodenal events, including symptomatic ulcers and their serious complications that can lead to fatal outcomes. The development of "coxibs" (selective cyclooxygenase-2 [COX-2] inhibitors) offered similar efficacy with reduced toxicity, but this promise of gastroduodenal safety has only partially been fulfilled, and is now dented with associated risks of cardiovascular or intestinal complications. Recent advances in basic science and biotechnology have given insights into molecular mechanisms of NSAID-induced gastroduodenal damage beyond COX-2 inhibition. The emergence of newer kinds of NSAIDs should alleviate gastroduodenal toxicity without compromising innate drug efficacy. In this review, novel strategies for avoiding NSAID-associated gastroduodenal damage will be described.

Abstract
A major clinical problem encountered with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as indomethacin, is gastrointestinal complications. Both NSAID-dependent cyclooxygenase inhibition and gastric mucosal apoptosis are involved in NSAID-produced gastric lesions, and this apoptosis is mediated by the endoplasmic reticulum stress response and resulting activation of Bax. Heat shock proteins (HSPs) have been suggested to protect gastric mucosa from NSAID-induced lesions; here we have tested this idea genetically. The severity of gastric lesions produced by indomethacin was worse in mice lacking heat shock factor 1 (HSF1), a transcription factor for hsp genes, than in control mice. Indomethacin administration up-regulated the expression of gastric mucosal HSP70. Indomethacin-induced gastric lesions were ameliorated in transgenic mice expressing HSP70. After indomethacin administration, fewer apoptotic cells were observed in the gastric mucosa of transgenic mice expressing HSP70 than in wild-type mice, whereas the gastric levels of prostaglandin E(2) for the two were indistinguishable. This suggests that expression of HSP70 ameliorates indomethacin-induced gastric lesions by affecting mucosal apoptosis. Suppression of HSP70 expression in vitro stimulated indomethacin-induced apoptosis and activation of Bax but not the endoplasmic reticulum stress response. Geranylgeranylacetone induced HSP70 at gastric mucosa in an HSF1-dependent manner and suppressed the formation of indomethacin-induced gastric lesions in wild-type mice but not in HSF1-null mice. The results of this study provide direct genetic evidence that expression of HSP70 confers gastric protection against indomethacin-induced lesions by inhibiting the activation of Bax. The HSP inducing activity of geranylgeranylacetone seems to contribute to its gastroprotective activity against indomethacin.

Abstract
AIM To investigate the effect of geranylgeranylacetone (GGA) on the progression of atrophic gastritis in rats and its potential mechanism. METHODS Atrophic gastritis was induced in Sprague-Dawley rats with 0.1% ammonia solution, 60% ethanol, and 20 mmol/L deoxycholic acid for 24 weeks. Accompanied by the induction of atrophic gastritis, 200 mg/kg GGA was administered by oral gavage for 8 weeks (weeks 17-24). The histological changes in gastric mucosa were quantitated by the index of inflammation, the gastric mucosal thickness, and the amount of glands of 1 mm horizontal length in antrum. Endogenous heat shock protein (HSP)70 levels and distribution were determined by immunoblotting and immunohistochemistry in gastric mucosa. RESULTS GGA alleviated the pathological progression of atrophic gastritis with inflammation relief (inflammation index: 1.40 in the GGA group and 1.65 in the atrophic gastritis group) and glandular restoration (mucosal thickness and quantity of glands: 194.3 microm and 38.7 mm in the GGA group; 123.3 microm and 32.7 mm in the atrophic gastritis group; P<0.05). GGA significantly induced HSP70 synthesis (P<0.05). Moreover, quercetin, an inhibitor of HSP70 expression, aggravated the infiltration of inflammatory cells and glandular loss in the antrum. CONCLUSION GGA prevented the progression of atrophic gastritis in rats via the induction of HSP70 expression.

Abstract
Gastric lesions result from an imbalance between aggressive and defensive factors. Indirect lines of evidence suggest that heat shock proteins (HSPs) induced by various aggressive factors provide a major protective mechanism. In this study, we compared gastric ulcerogenic response in wild-type mice and in those lacking heat shock factor 1 (HSF1), a transcription factor for hsp genes. The severity of gastric lesions induced by ethanol or hydrochloric acid was worsened in HSF1-null mice. Immunoblotting, real-time reverse transcription-polymerase chain reaction, immunohistochemical analysis, and terminal deoxynucleotidyl transferase dUTP nick-end labeling assay revealed that the ethanol administration up-regulated gastric mucosal HSPs, in particular HSP70, in an HSF1-dependent manner, and more apoptotic cells were observed in the gastric mucosa of HSF1-null mice than in wild-type mice. In contrast, other parameters governing the gastric ulcerogenic response, including gastric acid secretion, gastric mucosal blood flow, and prostaglandin E(2) levels, were not significantly affected by the absence of the hsf1 gene. Geranylgeranylacetone (GGA), a clinically used antiulcer drug with HSP-inducing activity, suppressed ethanol-induced gastric lesions in wild-type mice but not in heat shock factor 1 (HSF1)-null mice. The results suggest that the aggravation of irritant-induced gastric lesions in HSF1-null mice is due to their inability to up-regulate HSPs, leading to apoptosis. It is also suggested that the HSP-inducing activity of GGA contributes to the drug's antiulcer activity. This study provides direct genetic evidence that HSPs, after their HSF1-dependent up-regulation, confer gastric protection against the irritant-induced lesions.
