From Selye's and Szabo's Cysteamine-Duodenal Ulcer in Rats to Dopamine in the Stomach: Therapy Significance and Possibilities. Pharmaceuticals (Basel) 2023; 16:1699. [PMID: 38139825 PMCID: PMC10748240 DOI: 10.3390/ph16121699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 11/30/2023] [Accepted: 12/05/2023] [Indexed: 12/24/2023] Open
Abstract
We reviewed gastric ulcer healing by dopamine considering several distinctive duodenal key points. Selye and Szabo describe the cysteamine-induced duodenal ulcer in rats as a duodenal stress ulcer in patients. Szabo's cysteamine duodenal ulcer as the dopamine duodenal healing and cysteamine as a dopamine antagonist signifies the dopamine agonists anti-ulcer effect and dopamine antagonists ulcerogenic effect. From these viewpoints, we focused on dopamine and gastric ulcer healing. We mentioned antecedent studies on the dopamine presence in the stomach and gastric juice. Then we reviewed, in the timeline, therapy significance arising from the anti-ulcer potency of the various dopamine agonists, which is highly prevailing over the quite persistent beneficial evidence arising from the various dopamine antagonists. Meanwhile, the beneficial effects of several peptides (i.e., amylin, cholecystokinin, leptin, and stable gastric pentadecapeptide BPC 157, suggested as an acting mediator of the dopamine brain-gut axis) were included in the dopamine gastric ulcer story. We attempt to resolve dopamine agonists/antagonists issue with the dopamine significance in the stress (cysteamine as a prototype of the duodenal stress ulcer), and cytoprotection (cysteamine in small dose as a prototype of the cytoprotective agents; cysteamine duodenal ulcer in gastrectomized rats). Thereby, along with dopamine agonists' beneficial effects, in special circumstances, dopamine antagonists having their own ulcerogenic effect may act as "mild stress (or)" or "small irritant" counteracting subsequent strong alcohol or stress procedure-induced severe lesions in this particular tissue. Finally, in the conclusion, as a new improvement in further therapy, we emphasized the advantages of the dopamine agents' application in lower gastrointestinal tract therapy.

Abstract
Objective The association between antipsychotic use and gastric cancer risk remains unclear. Therefore, this study aimed to determine the association between antipsychotic exposure and the incidence of gastric cancer. Methods Using a nested case‐control design, a total of 34 470 gastric cancer patients and 163 430 nongastric cancer controls were identified from Taiwan's National Health Insurance Research Database between 1 January 1997 and 31 December 2013. We analyzed the data using a conditional logistic regression model to adjust for possible confounding variables. Results Antipsychotic use was independently inversely associated with gastric cancer risk after controlling for potential confounding factors including income, urbanization, medications, physical and medical illness, aspirin use, nonsteroidal anti‐inflammatory drug use and triple therapy. In addition, dose‐dependent trends against gastric cancer risk were also shown with individual antipsychotic compounds including thioridazine, haloperidol, sulpiride, clozapine, olanzapine, quetiapine, amisulpride, and risperidone. A sensitivity analysis showed that second‐generation antipsychotics had significant dose‐dependent effects in reducing the risk of gastric cancer risk in patients with and without peptic ulcer disease. Conclusions Antipsychotic use was inversely associated with gastric cancer risk, and dose‐dependent effects against gastric cancer were also seen with several individual antipsychotic compounds.

Gastroprotective Effects of Paeonia Extract Mixture HT074 against Experimental Gastric Ulcers in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:3546258. [PMID: 30906413 PMCID: PMC6398042 DOI: 10.1155/2019/3546258] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Accepted: 02/03/2019] [Indexed: 12/26/2022]
Abstract
Background Paeonia extract mixture HT074 is a standardized multiherbal mixture comprising extracts from Inula britannica flowers and Paeonia lactiflora roots, which are used to treat digestive disorders in traditional Korean medicine. This study was focused on elucidating the underlying mechanisms of the gastroprotective effects of HT074 in different gastric ulcer models. Methods Gastric lesions were induced in rats by an HCl/EtOH solution, water immersion-restraint stress (WIRS), and indomethacin. Gastric secretions were studied in pylorus-ligated rats, while mucus secretions were assessed by measuring alcian blue-binding capacity of mucus in the rat model of HCl/EtOH-induced gastric ulcer. Additionally, the involvement of nitric oxide (NO) and sulfhydryl compounds in HT074-mediated mucosal protection was elucidated using their inhibitors, i.e., NG-nitro- L-arginine methyl ester hydrochloride (L-NAME) and N-ethylmaleimide (NEM), respectively. Furthermore, the effects on indomethacin-induced cell death and prostaglandin E2 (PGE2) levels were assessed in AGS cells. Results Oral administration of HT074 significantly decreased gastric lesions induced by HCl/EtOH, WIRS, and indomethacin. Furthermore, it significantly decreased the volume, acidity, and total acidity of gastric juice in pylorus-ligated rats and increased the alcian blue-stained gastric mucus in HCl/EtOH-induced gastric ulcer in rats. Pretreatment with NEM abolished the gastroprotective effects of HT074, while L-NAME did not. In AGS cells, HT074 significantly reduced indomethacin-induced cell death and increased the PGE2 levels. Conclusions These findings suggest that HT074 has gastroprotective effects against various ulcerogens, including HCl/EtOH, immersion stress, and NSAIDs. These effects are attributed to the inhibition of gastric secretions and preservation of the gastric mucosal barrier by increased mucus production, which is partially mediated through endogenous sulfhydryl compounds and PGE2. Based on these findings, we propose that HT074 may be a promising therapeutic agent for gastritis and gastric ulcer.

Abstract
This study investigated the gastroprotective efficacy of synthesized scoparone derivatives on experimentally induced gastritis and their toxicological safety. Six scoparone derivatives were synthesized and screened for gastroprotective activities against HCl/ethanol- and indomethacin-induced gastric ulcers in rats. Among these compounds, 5,6,7-trimethoxycoumarin and 6,7,8-trimethoxycoumarin were found to have gastroprotective activity greater than the standard drug rebamipide; 6-methoxy-7,8-methylenedioxycoumarin, 6-methoxy-7,8-(1-methoxy)-methylenedioxycoumarin, 6,7-methylenedioxycoumarin, and 6,7-(1-methoxy)-methylenedioxycoumarin were found to be equipotent or less potent that of rebamipide. Pharmacological studies suggest that the presence of a methoxy group at position C-5 or C-8 of the scoparone's phenyl ring significantly improves gastroprotective activity, whereas the presence of a dioxolane ring at C-6, C-7, or C-8 was found to have decreased activity. In order to assess toxicological safety, two of the potent gastroprotective scoparone derivatives-5,6,7-trimethoxycoumarin and 6,7,8-trimethoxycoumarin-were examined for their acute toxicity in mice as well as their effect on cytochrome P450 (CYP) enzyme activity. These two compounds showed low acute oral toxicity in adult male and female mice, and caused minimal changes to CYP3A4 and CYP2C9 enzyme activity. These results indicate that compared to other scoparone derivatives, 5,6,7-trimethoxycoumarin and 6,7,8-trimethoxycoumarin can improve gastroprotective effects, and they have low toxicity and minimal effects on drug-metabolizing enzymes.

Abstract
The interaction of sulfobutylether-β-cyclodextrin (SBE-β-CD) with risperidone (RISP) was first described with luminol-SBE-β-CD chemiluminescence (CL) system by flow injection analysis (FIA). In luminol-SBE-β-CD CL system, the 1:1 SBE-β-CD···luminol(*) complexation could enhance CL intensity of luminol and produce the effect of complexation enhancement of CL (CEC). It was found that RISP could quench the CL intensity of SBE-β-CD···luminol(*) and caused the effect of complexation enhancement of quenching (CEQ), the formation constant K(R-CD) 3.4×10(4) L mol(-1) and the stoichiometric ratio 1:1 of RISP···SBE-β-CD complex were obtained by the proposed CL model. Association degree α 0.036 of RISP···SBE-β-CD complex was also given by CL method. Based on the linear relationship to the decrement of luminol-SBE-β-CD-RISP CL intensity and the logarithm of RISP concentration, RISP also can be quantified in the linear range of 3.0-500.0 nmol L(-1) with a detection limit of 1.0 nmol L(-1) (3σ). The proposed method was successfully applied to monitoring excreted RISP in human urine. It was found that RISP reached its maximum after oral administration for 1.5 h with the total excretion of 14.26% within 8.5 h; the elimination rate constant k and half-life time t(1/2) were 0.474 and 1.5 h, respectively.

Cellular localization of dopamine receptors in the gastric mucosa of rats. Biochem Biophys Res Commun 2011; 417:197-203.

Abstract
Dopamine (DA) plays a critical role in the protection of gastric mucosa and is mediated through corresponding receptors. However, the details of the expression of DA receptors (D1-D5) in the gastric mucosa are lacking. The present study investigated the expression and cellular localization of DA receptors in rat gastric mucosa by means of real-time PCR and immunofluorescent techniques. The results indicated that the mRNA expressions of all five subtypes of DA receptors were found in the gastric mucosa, among which the D2 level was the highest. The immunopositive cells of D1-D3 and D5 were primarily localized to the basilar gland of the epithelial layer in gastric corpus, but D4 immunoreactivity (IR) was only observed in the enteric nerve plexus. The D1, D2, and D5 IR were found in pepsin C-IR cells except D3. No IR of any DA receptor was detected in the H(+)/K(+)-ATPase- or mucin 6-IR cells. In conclusion, for the first time, this study demonstrates the predominant distribution of DA receptors in the chief cells, not the parietal and mucous neck cells, in rat gastric mucosa, thus suggesting that DA may not directly regulate the function of parietal cells or mucous neck cells, but it may modulate the function of chief cells through the D1, D2, and D5 receptors.
