We studied the effect of NF-κB blockade on the state of various pools of progenitor cells of the nervous tissue and the psychoneurological status of experimental animals with modeled Alzheimer's disease. Administration of scopolamine hydrobromide to C57BL/6 mice for 4 weeks was accompanied by the development of "persistent" disturbances in the orientation and exploratory behavior and mnestic function. An ameliorating effect of the NF-κB inhibitor on these cognitive disorders typical of senile dementia was revealed. At the same time, we observed an increase in the content of neural stem cells and committed neuronal precursors in the subventricular zone of the brain.

Regulating effect of Qifu Yin on intestinal microbiota in mice with memory impairment induced by scopolamine hydrobromide

Article

Author: Deng, Fanying ; Liu, Shiqi ; Wang, Yan ; Zhao, Fuxia ; Zhang, Qingling

ETHNOPHARMACOLOGICAL RELEVANCEQifu Yin (QFY) originates from "Jingyue Quanshu · Volume 51 · New Fang Bazhen · Buzhen" a work by Zhang Jingyue, a distinguished Chinese medical practitioner from the Ming Dynasty. QFY is composed of Ginseng Radix et Rhizoma, Rehmanniae Radix Praeparata, Angelicae Sinensis Radix, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle, Ziziphi Spinosae Semen, and Polygalae Radix. QFY is frequently employed to address memory loss and cognitive impairment stemming from vascular dementia, Alzheimer's disease (AD), and related conditions. Our findings indicate that QFY can mitigate nerve cell damage. Moreover, the study explores the impact of QFY on the calcium ion pathway and sphingolipid metabolism in mice with myocardial infarction, presenting a novel perspective on QFY's mechanism in ameliorating myocardial infarction through lipidomics. While this research provides an experimental foundation for the clinical application of QFY, a comprehensive and in-depth analysis of its improvement mechanism remains imperative.AIM OF THE STUDYTo clarify the regulatory mechanism of QFY on intestinal microecology in mice with memory impairment (MI).MATERIAL AND METHODSThe memory impairment mouse model was established by intraperitoneal injection of scopolamine hydrobromide. Kunming (KM) mice were randomly divided into blank group, Ginkgo tablet group (0.276 g/kg), QFY high, medium and low dose groups (17.2 g/kg, 8.6 g/kg, 4.3 g/kg). The effect on memory ability was evaluated by open field and step-down behavioral experiments. The morphological changes of nerve cells in the hippocampus of mice were observed by pathological method. The contents of superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT) and glutathione peroxidase (GSH-Px) in the brain tissue of mice were detected. The expression levels of CREB, Brain-Derived Neurotrophic Factor (BDNF) and Recombinant Amyloid Precursor Protein (APP) in the hippocampus of mice were determined using immunohistochemistry. The expression of N-methyl-D-aspartate receptor (NMDAR) and cAMP response element binding protein (CREB) related factors in the serum of mice was analyzed by ELISA. The levels of apoptosis signal-regulating kinase-1 (ASK1) and c-Jun N-terminal kinase (JNK) mRNA in the hippocampus were detected by quantitative real-time fluorescence polymerase chain reaction (qPCR). The intestinal feces of mice were collected, and the 16 S rDNA technology was used to detect the changes in intestinal microbiota microecological structure of feces in each group.RESULTSBehavioral experiments showed that the high-dose QFY group exhibited a significant increase in exercise time (P<0.05) and a decrease in diagonal time (P<0.05) compared to the model group. The medium-dose group of QFY showed a reduction in diagonal time (P<0.05). Additionally, the latency time significantly increased in the medium and high-dose groups of QFY (P<0.01). The number of errors in the low, medium and high dose groups was significantly decreased (P<0.05, P<0.01, P<0.01). The nerve cells in the CA1 and CA3 regions of QFY-treated mice demonstrated close arrangement and clear structure. Furthermore, the content of SOD significantly increased (P<0.01) and the content of MDA significantly decreased (P<0.05) in the low and high-dose QFY groups. The content of CAT in the medium-dose group significantly increased (P < 0.05). Immunohistochemical analysis showed a significant reduction in the number of APP expression particles in the CA1 and CA3 regions of all QFY groups. Moreover, BDNF expression significantly increased in the medium and high-dose groups, while CREB expression significantly increased in the low and medium-dose groups of QFY within the CA1 and CA3 regions. Serum analysis revealed significant increases in CREB content in the low, medium, and high dose groups of QFY (P<0.01, P<0.05, P<0.05), and decreases in NMDAR content across all QFY dose groups (P<0.01). PCR analysis showed a significant decrease in the contents of ASK1 and JNK in the medium-dose group (P<0.01). Microecological analysis of intestinal microbiota demonstrated a significant restoration trend in the relative abundance of Fusobacteria, Planctomycetes, and Verrucomicrobia (P<0.01 or P<0.05) at the phylum level in the QFY groups. At the genus level, Akkermansia, Paramuribaculum, Herminiimonas, Erysipelatoclostridium and other genera in the QFY groups showed a significant trend of relative abundance restoration (P<0.01 or P<0.05).CONCLUSIONQFY can improve the memory of MI animals induced by scopolamine hydrobromide by restoring the homeostasis of intestinal microbiota and regulating related indexes in serum and brain tissue.

A Rabbit Dry Eye Model Induced by Subcutaneous Scopolamine

Article

Author: Huang, Guofu ; Zhou, Shiyou ; Tian, Bishan ; Duan, Sujuan ; Huang, Shitong

PURPOSETo establish and characterize a dry eye model in New Zealand rabbits by subcutaneous injections of scopolamine hydrobromide (SCOP).METHODSTwenty New Zealand male rabbits were injected subcutaneously SCOP for 14 consecutive days; subcutaneous saline was used as a negative control. The correlated clinical parameters of ocular surface dryness were detected in vivo using tear secretion and corneal fluorescein staining. The expression of IL-1β and TNF-α on the ocular surface and in lacrimal glands were analyzed by real-time PCR and western blot on the 14th day. The expression of Mucin-5 subtype AC (MUC5AC) was detected by Immunofluorescence staining in conjunctival tissue.RESULTSThe SCOP-treated rabbits exhibited significantly decreased aqueous tear secretion and increased corneal fluorescein staining scores over time. Both the mRNA expression levels and the protein expression levels of IL-1β and TNF-α were significantly increased after SCOP treatment compared with those after saline treatment. The loss of conjunctival MUC5AC was found in the SCOP-injected rabbits. Some infiltrated inflammatory cells and atrophic acinar cells were observed in the lacrimal gland after SCOP treatment. The disordered structures of the ocular surface and lacrimal glands were also observed.CONCLUSIONSThis study showed that repeated subcutaneous SCOP injections successfully elicited some of the typical dry eye symptoms commonly seen in humans.

Defender’s plans for motion sickness nasal gel stop with FDA rejection

Nasa is helping with Defender’s development of DPI-386, as astronauts are particularly susceptible to motion sickness in space. Image credit: Shutterstock/Supamotionstock.com. The FDA has decided to not approve Defender Pharmaceuticals’ intranasal scopolamine candidate for motion sickness, issuing a complete response letter (CRL) to the US-based company. Defender’s drug, known as DPI-386, is indicated for the prevention of nausea and vomiting induced by motion in adults. Defender’s CEO Barry I Feinberg said the company plans on scheduling a formal meeting with the FDA to discuss the issues raised and to create a plan going forward, in a 30 January press release. DPI-386 is a nasal gel version of the antimuscarinic drug scopolamine, first approved by the FDA as a transdermal patch in 1979, according to the drug’s label . Currently, patches are placed behind the ear and work with high efficacy by depressing the parasympathetic nervous system. The gel could be particularly useful for astronauts and military personnel who are frequently exposed to motion. Nasa joined forces with Epiomed Therapeutics to develop a fast-acting nasal spray version of scopolamine in 2012. According to the St Louis Post-Dispatch , Defender purchased Epiomed in 2014 and was founded the same year. Headquartered in St Louis, Missouri, the company has also worked with the United States Naval Medical Research Unit. See Also: Tyra Biosciences’ TYRA-300 gains FDA rare paediatric disease status Revolo advances plans to tackle eosinophilic esophagitis with orphan drug tag Defender’s formulation aims for rapid absorption to induce quicker onset. In a Phase III trial more than 500 participants, who usually get motion sick, had improved symptoms after being exposed to open sea conditions while using DPI-386. Subjects who received the nasal gel demonstrated lower incidences of vomiting and fewer requests for rescue medication compared to a placebo group. The incidence of moderate to severe nausea was also lower. In a September 2023 statement announcing the new drug application (NDA) acceptance, Defender said results from five phase III trials were submitted as evidence. The NDA was assigned priority review status by the FDA at the request of the US Navy. Feinberg added: “We remain confident that our intranasal scopolamine is a safe and effective therapy for the prevention of motion sickness, and we will work closely with the FDA to ensure that we can bring this innovative new product to the market.” Defender is also exploring the use of DPI-386 in major depressive disorder (MDD) with suicide ideation, chemical exposure accidents, and virtual reality sickness. In October 2023, Defender announced further collaborations with Nasa to study DPI-386 in Phase II trials to mitigate G-transition-induced motion sickness and enhance sensorimotor performance. Scopolamine recently made the news beyond the healthcare sector after rising incidences of it being linked to criminal activity. In June 2023, the US Embassy in Colombia highlighted the sedative side effects of the drug are being increasingly used to target tourists in the country. In certain doses, the drug can cause unconsciousness for 24 hours or more. Scopolamine was also the first drug to infamously garner the “truth serum” tag.

Defender Pharmaceuticals Receives Complete Response Letter from the U.S. Food and Drug Administration for its Intranasal Scopolamine (DPI-386) New Drug Application for the Prevention of Nausea and Vomiting Induced by Motion in Adults

ST. LOUIS, Jan. 30, 2024 (GLOBE NEWSWIRE) -- Defender Pharmaceuticals, Inc. (the “Company” or “Defender”), a privately held life sciences company based in St. Louis, today announced that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) in response to the Company’s New Drug Application (NDA) for intranasal scopolamine (DPI-386) for the prevention of nausea and vomiting induced by motion in adults. “Following our review of the CRL, we plan on scheduling a formal meeting with the FDA to fully understand the issues raised in the CRL so we can develop and implement a comprehensive action plan,” said Barry I. Feinberg, M.D., President & CEO of Defender Pharmaceuticals. “We remain confident that our intranasal scopolamine is a safe and effective therapy for the prevention of motion sickness, and we will work closely with the FDA to ensure that we can bring this innovative new product to the market.” About intranasal scopolamine (DPI-386) Development ProgramDefender has worked with the United States Naval Medical Research Unit (NAMRU-D) and the National Aeronautics and Space Administration (NASA) on its intranasal scopolamine development program that is focused on specific military personnel and astronauts. To date, more than 1,300 patients have participated in Defender clinical studies, including over 500 participants in the DPI-386-MS-33 study. Given the successful outcome of DPI-386-MS-33, Defender has submitted a New Drug Application (NDA) to the Food and Drug Administration (FDA) for DPI-386 Nasal Gel for the prevention of nausea and vomiting induced by motion in adults. Defender is also developing intranasal formulations designed to treat a wide variety of indications. We believe these new products have the potential to help safeguard health across civilian and military populations. About Motion Related DiscomfortCertain motions cause discomfort in individuals while engaged in a variety of leisure or travel related activities. Most forms of travel, whether on land, in the air, or on the water, can trigger symptoms such as nausea and vomiting (example: flying, boating/fishing, car, bus, and train). Symptoms induced by motion can also have a detrimental impact on the ability of various military personnel and astronauts to perform assigned duties, potentially impacting readiness and negatively impacting resources. Motion related discomfort is a common and transient response to unfamiliar or unnatural motion or contradictory spatial sensory information, resulting in decrements to performance of tasks, pallor, cold sweating, nausea and vomiting. Prolonged exposure to certain motions may induce sopite-related symptoms such as loss of drive and concentration, drowsiness, sleepiness, apathy, depression, and a feeling of impending doom.

FDA rejects Defender’s motion sickness treatment for astronauts

Defender Pharmaceuticals said Tuesday that the FDA declined to approve intranasal scopolamine (DPI-386), a motion sickness treatment intended for military personnel and astronauts. In a statement, Defender CEO Barry Feinberg said the company plans “on scheduling a formal meeting with the FDA to fully understand the issues raised in the CRL (complete response letter),” but did not disclose what those issues were. The company did not respond to a request for comment from FirstWord. Defender worked with NASA and the US Naval Medical Research Unit to develop the treatment – a nasal gel formulation of scopolamine, which has been approved since 1979 as a transdermal patch to treat motion sickness, according to the drug’s label. Scopolamine acts as a competitive inhibitor at cholinergic receptor sites of the parasympathetic nervous system. The FDA submission included data from a Phase III trial which showed intranasal scopolamine met the primary endpoint of significantly reducing vomiting and the need for rescue treatment versus placebo.
