Nature offers both therapeutic substances and toxic threats. The rise in popularity of plant-based remedies, often perceived as safer alternatives to conventional medicine, presents regulatory challenges due to limited pharmacological and safety data. Among the poorly characterized natural compounds, furanic compounds stand out. These molecules, defined by their furan or dihydrofuran ring, are found in plants, fungi, tobacco smoke, exhaust gases, and food, particularly roasted or processed ones such as coffee and baby food. Despite being labelled as potentially carcinogenic, their mechanisms of toxicity remain underexplored. Metabolic activation by cytochrome P450 enzymes converts these compounds into highly reactive 1,4-enedial intermediates, capable of trapping nucleophiles such as DNA and proteins, triggering oxidative stress and cellular injury. Such biochemical events contribute to a range of toxic effects across multiple organs, particularly the liver and tissues exposed via inhalation or ingestion. Chronic exposure has been linked to inflammation, tissue injury, and morbidity. With rising levels of environmental furans driven by industrial emissions and global warming, there is an urgent need for predictive tools to assess their toxicological profile. Our work aims to develop a robust electrochemical model that mimics CYP450-mediated activation to screen the toxic potential of furanic compounds. We investigated the relevance of redox potential as a predictive parameter for furan toxicity, and the correlation of this electrochemical model with the measure of CYP3A4 inhibition in a cell-based in vitro model using HepaRG cells. By simulating enzyme-like conditions, the electrochemical model could perform as a fast, mechanistic, and predictive tool for assessing the risks associated with exposure to both naturally occurring and other environmental furans, finally enabling more systematic safety assessments.

Acute kidney injury (AKI) secondary to hematotoxic snakebite remains underrecognized and under documented, especially in sub-Saharan Africa. We report the case of a 39-year-old woman bitten on the left foot by a West African carpet viper (Echis ocellatus) while farming in Northern Cameroon. She received six doses of antivenom and three units of blood at Poli district referring center before being transferred to Garoua Regional Hospital, eight days post-bite. At admission, she presented with hematemesis, tumefaction, hematuria, anuria, vomiting, and signs of volume overload. Despite being fully conscious, she was hemodynamically unstable (HR 93 bpm, BP 144/79 mmHg, Temp 36.6 °C), with pronounced pallor and leg swelling. Laboratory evaluation revealed leucocytosis, anaemia (Hb 7.3 g/dL), thrombocytopenia, and severe renal impairment (urea: 4.8 g/L; creatinine: 198 mg/L). Urinalysis showed proteinuria and ascorbic acid traces. Coagulation tests were abnormal. She was managed with four additional doses of PANAF-Premium polyvalent antivenom, four units of blood, and 12 haemodialysis sessions. Renal function and urine output progressively improved, allowing discharge on October 18. Follow-up on November 1 revealed fever, vomiting, and epigastric pain; she was treated for severe malaria and hyperalgesic gastritis. She has since resumed normal activities. This case demonstrates that even delayed AKI secondary to envenomation can be successfully reversed through sustained dialysis, prompt antivenom use, and supportive care. The absence of adverse events underlines the favorable safety profile of PANAF-Premium. Continued availability of free antivenom and renal support services is essential to improving outcomes in high-risk, rural settings.

In viper envenomation, the venom is typically injected into the subcutaneous or muscle tissue and is primarily absorbed through the lymphatic system before reaching the systemic circulation. Although antivenoms are central to snakebite treatment, most research has focused on their pharmacokinetics in the blood, leaving the role of the lymphatic system poorly investigated. Yet, this is where venom initially accumulates, suggesting that the lymph may be a critical space for early neutralization. The study aimed to improve our understanding of how antivenom behaves in the lymphatic system and to establish whether the route of administration, intravenous (i.v.) or intramuscular (i.m.), affects its ability to reach and neutralize venom at this early stage. We used sheep as a large animal model to simulate the human envenomation dynamics. A venom dose corresponding to a dose injected in the typical envenomation was applied subcutaneously (s.c.), followed by the antivenom administration either via an i.v. infusion or an i.m. injection. Lymph was continuously collected from the thoracic duct, and blood samples were taken at defined time points. Venom and antivenom concentrations were quantified using in-house ELISA assays. Our focus was on how quickly the antivenom reached the lymph, its peak levels, and the relationship with the decline of the venom in the same compartment. The findings reveal that the lymphatic system is not just a passive transport route, but also a key site of action. The appearance of antivenom in lymph varies depending on the administration route, and these differences can influence the effectiveness with which venom is neutralized before entering the bloodstream. Understanding this dynamic could help to refine treatment protocols and improve outcomes for snakebite patients, especially in settings where rapid intervention is critical.

The WHO declared snakebite as a neglected tropical disease. Though the exact number of snakebite cases is not known, estimated results showed that 5.4 million people are bitten by snakes worldwide each year, and 2.7 million envenoming cases occur. Around 81,000 to 138,000 deaths occur every year globally by snakebite envenoming, and three times more amputations occur along with many other disabilities annually. This study investigates the therapeutic effects of honey-derived phenolics on snakebite envenomation to reduce its impact. Cobra venom was partially characterized by SDS-PAGE, revealing three protein types. The partial characterization of antivenom was done by microscopy, and the MIC of phenol (m-cresol) was determined to measure its concentration as a preservative in antivenom. The ideal concentration was 16% for phenol (m-cresol). Saudi and Kashmir honey samples were analyzed for their potential role in countering envenomation. The physiochemical analysis, including pollen analysis, HMF presence, ash, moisture, pH, color, sucrose, and reducing sugars were analyzed. Microscopy showed a floral nature of both samples, including 13 different types of pollens. The total phenol content (TPC) of Saudi honey was 8.6 mg GAE/100 g of dry extract whereas Kashmir honey was 8.3 mg GAE/100g of dry extract. HPLC was used to assess the presence of phenolics. The in vivo results were significant, achieving a 100% survival rate in albino mice. Such synergy among honey- derived phenolics may neutralize venom toxins and enhance antivenom efficacy, opening opportunities to study phenolic compounds as adjuvants in antivenom production and advancing global snakebite management.

Snakebite envenoming remains a major global health issue, causing over 100,000 deaths each year and leaving many survivors with long‑term disabilities. The current therapeutic plasma‑derived methods may save plenty of lives but suffer from variable efficacy, risk of adverse reactions, batch‑to‑batch inconsistency and high costs. To overcome these problems, we are developing a simple antivenom based on recombinant single‑domain antibodies (VHHs). By combining a small mix of VHHs that neutralize key toxins from several venomous species, we aim to create a more broadly applicable and consistent treatment. In this poster, I will explain how we discover cross-reactive and high-affinity VHHs that neutralize the major viper toxins from sub‑Saharan Africa. We first purify four toxin families, — phospholipase A₂s (PLA₂s), disintegrins, snake‐venom metalloproteinases (SVMPs), and snake‐venom serine proteinases (SVSPs), —and then use phage display technology to select VHHs with strong, cross‑reactive binding. Finally, I will discuss the results from in vitro assays that identify the top VHH candidates.

Snake venom that affects the blood contain multitude proteins, including enzymes with diverse enzymatic potential to interfere on haemostatic and thrombosis mechanism when bites human. This study was carry out to investigate the biological effects of Echis carinatus (IEC) venom and its fractions on human body in Iran. This mixture has components with either synergistic or antagonistic effects on blood coagulation. Snake venoms far than some therapeutic effects, can be studied for the presence of endogenous antivenins that protect against their own toxins. In fact, without antivenin treatment, biological disturbances following snake envenomation in human quickly worsen and cause death. In-vitro and in-vivo coagulant assays were conducted to determine the effects of IEC venom and its fractions as well as the effectiveness of the polyvalent antivenin in neutralizing haematological manifestations. The results of the PT, APTT, TCT, FCT, haemorrhagic, defibrinogenating, platelet aggregation tests, and plasma hematologic parameters revealed the multifunctional features of toxins which can act on their multiple protein targets of prey. In this study, It is shown that EC bites can create severe haematological disorders within the first hours after envenoming, which require medical attention as soon as possible to reduce the severity of clinical symptoms. Further, numbers of purified fractions are more toxic than the crude venom. Eventually, in this study it is shown that polyvalent antivenin from Razi institute in Iran could led to neutralize the IEC venom biological and haematological effects.
Caught in the Kv web: screening arachnid venoms for modulators of Kv7.2/7.3 channels

Spider venoms are a rich source of disulphide-rich peptides with potent and selective activity on ion channels. We are leveraging this natural diversity to identify modulators of Kv7.2/7.3 channels (encoded by KCNQ2/3), which underlie the neuronal M-current and play a critical role in controlling excitability. Gain-of-function (GoF) mutations in these channels are increasingly recognised in patients with developmental and epileptic encephalopathies (DEEs), many of whom are resistant to current antiepileptic treatments. To date, no approved therapies exist that specifically target GoF Kv7.2/7.3 dysfunction.Using high-throughput electrophysiology and spider venom fraction screening, we identified two novel peptides that act as negative modulators of voltage-dependent Kv7.2/7.3 activation. These represent the first venom-derived peptides shown to shift Kv7.2/7.3 gating in a manner that may counteract GoF mutations and restore more physiological excitability. Our findings support the potential of spider venom peptides as scaffolds for precision therapeutics targeting Kv7.2/7.3-related epilepsies. Ongoing work focuses on screening and identifying more venoms and peptides.

Objective: Vietnam (VN) is an agricultural & tropical country. It is very convenient for developing of the poisonous snakes. They are the perpetrators harming up to 30,000 (thirty thousand) victims per year with a very high mortality rate (19.5%), because there was no anti-venom (AV). The objective of present research program was to manufacture specific AV to each poisonous snake species, promptly meeting the clinical requirements to save the lives of envenomed victims in VN. According to the guidance of WHO and David Warrell, 03 venomous snake families with 13 species of medical importance in VN have been established. 06 specific AV types with each most dangerous and common venomous snake have been successfully researched and manufactured according to the technical process F(ab’)2. They are Naja kaouthia, Calloselasma rhodostoma, Bungarus candidus and Bungarus multicinctus, Ophiophagus hannah, Naja siamensis. After meeting all quality inspection criteria at the National Institute of Vaccine and Bio-products, the Ministry of Health of VN, AVs have been allowed to promptly apply clinical emergency to save the lives of 4,813 (Four thousand, eight hundred and thirteen) envenomed victims, who were threatened by death. The mortality rate of severely envenomed victim group had decreased from 19,5% to 0.24%. Permanent deformity rate had reduced from 14% to 05%. Amputation rate had reduced from 11% to 01%. However, the above research results were only the initial step and limited in the laboratory. Snakebite has been still neglected in VN. We urgently call for the attention of the State, domestic and foreign philanthropists to support the development of manufacturing AV program in order to timely save the lives of many thousands of envenomed victims in VN, Laos and Cambodia.
