Quantitative analysis of excipients to the permeability of BCS class III drugs

Article

Author: Ouyang, Defang ; Wang, Shuo ; Liu, Dongyang

BCS III drugs exhibit high solubility and low permeability, and some excipients were reported to increase their permeability. Although some permeability-enhancing excipients were investigated, permeability-enhancing strategy still need to be improved. Firstly, we established a database and analyzed the possible effects of excipients. Sodium lauryl sulfate (SLS) was found to be the most-used permeability-enhancing excipients. Moreover, the quantitative models for predicting P_app and P_eff of BCS III drugs with SLS were developed, and statistically meaningful descriptors include molecular weight (MW), pKa, logP, solubility, hydrogen bond (HB) count, rotatable bond count (RBC), and topological polar surface area. The models demonstrated a good fit and effective predictive capability with all the correlation R² values over 0.7. Hydrogen bonding remains the most significant factor in enhancing drug permeability with SLS, while hydrophilicity is also vital in this process. It was also found that MW, logP, pKa, and RBC play significant roles in paracellular transport. In summary, current research did the systematic and quantitative analysis of BCS III drugs and their excipients, which may accelerate formulation research on BCS III products.

This study is to demonstrate the protection of atractylenolide III (AT III) on intestinal barrier dysfunction in ulcerative colitis (UC). UC model was established by 3% dextran sulfate sodium (DSS), and TNF-α was used to induce dysfunction in the intestinal epithelial barrier. TEER, FD-4 transmembrane flux and DAI were measured. Histopathological changes was identified by H&E staining, TJ structure changes were observed by TEM, IL-1β and TNF-α contents were measured by ELISA, bacterial translocation was investigated by FISH. The expressions of ZO-1, occludin, and the proterins in the MLCK/p-MLC and NF-κB pathways were analyzed by Western blotting or immunofluorescence. The results indicated that AT III alleviate the symptoms of DSS-induced colitis, reduce the disruption of intestinal epithelial barrier, and decrease FD4. Moreover, AT III inhibited the destruction of intestinal epithelial TJ structure and bacterial translocation in UC mice. AT III reversed the high levels of IL-1β and TNF-α, the decrease of occludin, ZO-1 expressions. Furthermore, AT III showed similar effects to PDTC (pyrrolidinedithiocarbamate) in ameliorating the disruption of the TNF-α-induced TEER and FD-4 disruption, MLCK protein expression, and MLC2 phosphorylation. In conclusion, AT III mitigates the dysfunction of intestinal epithelial barrier in UC through the NF-κB-mediated MLCK/p-MLC signaling pathway.

Trivalent arsenicals induce skin toxicity through thiol depletion

Article

Author: Kim, Chang-Hwan ; Lim, Kyung-min ; Hwang, Jee-hyun ; Chung, Han Young ; An, Gwang Jin ; Hwang, Jee-Hyun ; Lim, Kyung-Min

Arsenic, a widespread environmental contaminant, is highly toxic to human health. Arsenic exposure is associated with the occurrence of skin lesions and diseases. This study investigated the dermal toxicity of trivalent arsenicals (As^III and MMA^III) and its underlying mechanism using human keratinocyte cell line and ex vivo porcine skin. As^III and MMA^III induced concentration-dependent cell apoptosis and necrosis in HaCaT cells, which was confirmed in ex vivo porcine skin. As^III and MMA^III increased reactive oxygen species generation and GSH depletion. Interestingly, radical scavenger antioxidants such as Vitamin C failed to mitigate arsenic-induced cytotoxicity, while thiol-containing compounds effectively alleviated it, suggesting a key role of thiol depletion in the trivalent arsenical-induced dermal toxicity. DMSA showed the strongest protective effects against As^III and MMA^III-induced cytotoxicity in HaCaT cells. Of note, DMSA restored arsenical-induced tissue damage, and reduced the apoptosis in ex vivo porcine skin, highlighting its potential use to alleviate arsenic-induced skin lesions and diseases.

New study shows certain combinations of antiviral proteins are responsible for lupus symptoms and affect treatment outcomes

Researchers say they have uncovered insights as to why lupus symptoms and severity present differently in individuals with the autoimmune condition, which affects up to 1.5 million Americans. The team says this is a crucial step forward in understanding biological mechanisms behind lupus, and may also lead to shifts in how clinicians treat patients with the condition. In a new study, researchers from Johns Hopkins Medicine say they have uncovered insights as to why lupus symptoms and severity present differently in individuals with the autoimmune condition, which affects up to 1.5 million Americans. The team says this is a crucial step forward in understanding biological mechanisms behind lupus, and may also lead to shifts in how clinicians treat patients with the condition. The full report, published in Cell Reports Medicine on May 13, concludes that specific combinations and elevated levels of immune system proteins, known as interferons, are associated with certain lupus symptoms such as skin rashes, kidney inflammation and joint pain. Interferons normally help to fight infection or disease, but are overactive in lupus, causing widespread inflammation and damage. The study also shows that other common lupus-related symptoms cannot be explained by increased interferon levels. "For years, we have accumulated knowledge that interferons play a role in lupus," says corresponding author and rheumatologist Felipe Andrade, M.D., Ph.D., associate professor of medicine at the Johns Hopkins University School of Medicine. He says this research began with questions about why certain lupus treatments were ineffective for some patients. "We have seen instances where the patient surprisingly didn't improve -- we wondered if certain interferon groups were involved." Some lupus treatments are designed to suppress a specific group of interferons, known as interferon I. In clinical trials for these treatments, the team observed some patients failing to improve, despite genetic tests showing high interferon I levels before treatment, or what experts call a high interferon signature. The team believed that two other interferon groups, interferon II and interferon III, may be to blame for these poor treatment responses. To investigate, the team looked at how different combinations of interferon I, II or III, and their overactivity, may present in people with lupus. Researchers took 341 samples from 191 participants to determine the activity of the three interferon groups, and used human cell lines engineered to react to the presence of each specific interferon group to analyze the samples. Through this process, researchers determined that the majority of participants fell into four categories: those only with increased interferon I; those with a combination of increased interferons I, II and III; those with a combination of increased interferons II and III; or those with normal interferon levels. Researchers were able to use these findings to also make several associations between these interferon combinations and lupus symptoms. In those with elevated interferon I, lupus was mainly associated with symptoms affecting the skin, such as rashes or sores. Participants with elevated levels of interferon I, II and III exhibited the most severe presentations of lupus, often with significant damage to organ systems, such as the kidneys. Not every symptom found in lupus was associated with elevated interferons, though. The formation of blood clots and low platelet counts, which also affect clotting, did not have an association with increased levels of interferon groups I, II or III. Researchers say this indicates that both interferon-dependent and other biological mechanisms are involved in this complex disease. The study also found that genetic testing of genes associated with these interferon groups, or the interferon signature, did not always indicate elevated interferon levels. They plan to investigate this in future studies. "What we've seen in our study is that these interferon groups are not isolated; they work as a team in lupus and can give patients different presentations of the disease," says rheumatologist Eduardo Gómez-Bañuelos, M.D., Ph.D., assistant professor of medicine at the Johns Hopkins University School of Medicine and the study's first and additional corresponding author. Evaluating a patient's elevated interferon combinations allows for a better understanding of how they may react to treatments, and would allow clinicians to group them into clinical subtypes of lupus, Gómez-Bañuelos explains. Additional contributors to this work include Daniel Goldman, Victoria Andrade, Erika Darrah and Michelle Petri, affiliated with the Johns Hopkins University School of Medicine. Darrah is now also affiliated with AstraZeneca. Funding for this project includes National Institutes of Health grant numbers R21 AI147598, R21 AI169851, R21 AI176766 and R01 AR069572, as well as from the Jerome L. Greene Foundation.

Octapharma presents new data at ISTH 2023 in an ongoing commitment to improve the lives of people with bleeding disorders

LACHEN, Switzerland, June 6, 2023 /PRNewswire/ -- Octapharma to present new clinical and scientific findings for wilate®, Nuwiq®, octaplex® and atenativ® at the upcoming ISTH 2023 Congress New data and clinical study developments will be presented in nine posters and during two Supported Symposia The most recent developments from Octapharma's Haematology and Critical Care portfolios will be presented at the 31st Congress of the International Society on Thrombosis and Haemostasis (ISTH) on June 24–28, 2023, in Montréal, Canada. The data will be featured in nine poster presentations and two Supported Symposia during this key international meeting. Octapharma is a proud Silver Supporter of the ISTH 2023 Congress. There will also be a promotional booth focusing on modern approaches to bleeding and coagulation management. People with inherited bleeding disorders, such as haemophilia A and von Willebrand disease, are at risk of recurrent and prolonged bleeds placing a heavy burden on patients' lives. In addition to the risk of potentially life-threatening bleeds, increased bleeding is associated with long-term consequences that severely impair patients' quality of life. Patients with a deficiency of the prothrombin complex of coagulation factors are also at increased risk of bleeding. Such deficiencies may be inherited but can also be acquired and may be induced by the use of vitamin K antagonists (VKA) for anticoagulation therapy. During urgent surgery, rapid correction of the deficiency is required and can be achieved through the use of four-factor prothrombin complex concentrates (4F-PCC). 4F-PCC can also be used to control major bleeding associated with the use of direct oral anticoagulant (DOAC) therapy in patients with factor Xa inhibitors. The presentations at ISTH 2023 reflect Octapharma's long-term commitment to improving patient care and addressing unmet clinical needs. "We are proud to showcase our new data and provide updates of studies from across Octapharma's haematology and critical care portfolios at ISTH 2023," said Olaf Walter, Board Member at Octapharma. "Despite advances in the field, people with bleeding and coagulation disorders still face considerable challenges surrounding bleed management. At Octapharma, we strive to address such challenges head-on with the goal to improve the day-to-day lives of patients." Poster Presentations The WIL-31 study investigated the efficacy and safety of prophylaxis with wilate® in patients with von Willebrand disease (VWD) of any gender with VWD type 1, type 2 (except 2N) or type 3. The results of the study show that wilate® prophylaxis is highly effective at reducing the number of bleeds in children and adults, and provides compelling evidence to support the use of regular prophylaxis in patients with severe VWD. Further data on the efficacy and safety of wilate® prophylaxis is being collected in the WIL-33 study in children under six years of age. The goals and design of this study will be presented. Prophylaxis is already the standard of care for people with haemophilia A. The results of an indirect comparison show that fewer patients experienced bleeds when receiving personalised prophylaxis with Nuwiq® rather than prophylaxis with a comparator factor VIII (FVIII) product. New data exploring differences in the binding of different recombinant FVIII products to platelets in vitro will be shared in a separate poster. Although haemophilia A mainly affects males, female carriers may also have reduced levels of FVIII and be at increased risk of bleeding, especially during traumatic events such as surgery. Data from a retrospective case series of female haemophilia A carriers who were prescribed Nuwiq® during surgery at the Bonn Haemophilia Centre will provide an insight into the effective treatment of females. MOTIVATE is an ongoing, international investigator-initiated study made possible through funding from Octapharma AG, evaluating the management of haemophilia A patients with inhibitors. The Coordinating investigators, Drs Carmen Escuriola Ettingshausen and Robert F. Sidonio Jr., will provide an update on the study status as a poster at the Congress. The LEX-210 study will evaluate the haemostatic efficacy of octaplex® in patients with acute major bleeding receiving factor Xa inhibitors. As anti-factor Xa (anti-Xa) activity levels will be measured in these patients, the correlation between heparin-calibrated and specific factor Xa inhibitor assays has been analysed and will be presented. The results from the first head-to-head, phase 3, randomised, controlled trial (LEX-209) comparing two 4F-PCCs in patients on VKA anticoagulation who need urgent surgery will be presented, with a focus on dosing and haemostatic efficacy results. The results show that octaplex® was non-inferior to control 4F-PCC for rapid vitamin K antagonist reversal in patients undergoing urgent surgeries with significant bleeding risk. The posters will be presented at the following times: Sunday June 25, 18:30–19:30 ET PB0163. Differential binding of recombinant FVIII products to platelets, and impact of FVIII on VWF expression and platelet contractility in vitro. Presenting author: Viola Vogel. PB0235.

Supported Symposia New clinical and scientific data, as well as updates on ongoing and new studies, will be shared during two Supported Symposia during the Congress. Final Results of the WIL-31 Study – A New Treatment Standard for von Willebrand Disease Patients with Severe Bleeding? Monday June 26, 13:15–14:30 ET, Room 511 Chair: Alok Srivastava, Christian Medical College, Vellore, India The symposium will focus on new data regarding the use of wilate® prophylaxis in children and adults to improve the lives of people with VWD. Topics presented will include the importance of prophylaxis, including current guidelines on the management of VWD and how to identify patients who may benefit from prophylactic treatment. Key learnings from the WIL-31 VWD prophylaxis study will be shared and case presentations of select WIL-31 patient cases from across the globe will be discussed. Bringing Together Two Worlds – Scientific and Clinical Insights for All-Round Bleed Protection in Haemophilia A Tuesday June 27, 13:15–14:30 ET, Room 511 Chair: Davide Matino, McMaster University, Hamilton, Ontario, Canada Octapharma's symposium on haemophilia A this year is dedicated to both, scientists and clinicians. The speakers will present data from the NuPreviq trial and the matching adjusted indirect comparisons (MAIC) analyses of Nuwiq® vs extended half-life (EHL) products as well as introduce the PROVE study. Topics discussed during this symposium will also include the role of platelets in FVIII binding, impact of prophylaxis on microRNA expression (biomarkers of joint and bone health) and how to utilise the power of RNASeq to understand inhibitor development. Both symposia will be open to congress participants in Montréal and will be streamed live for participants not attending the Congress. The opportunity to ask questions will be available at both symposia. Larisa Belyanskaya, Head of IBU Haematology at Octapharma commented: "We are delighted to showcase new data from WIL-31, which supports the importance of prophylaxis in people with von Willebrand disease, and to discuss scientific and clinical questions that need to be address to advance the management of people with haemophilia A."
