Inhibition of respiratory syncytial virus by Daclatasvir and its derivatives: synthesis of computational derivatives as a new drug development

Article

作者: Afreen, Shagufta ; Mitra, Debanjan ; Abdalla, Mohnad ; Das Mohapatra, Pradeep K.

The most common cause of respiratory tract illness in newborns and young children is the respiratory syncytial virus (RSV). There is no approved vaccination or specific antiviral medication for RSV infections. Here, an attempt has been made to explore the potential of currently marketed drugs as well as their probable derivatives to improve the possibility of developing stronger medications against RSV. From the 100 synthetic drug compounds library, the best drug molecule was identified through drug-likeness properties, toxicity, molecular docking and molecular dynamics simulations. Molecular Mechanics Generalized Born Surface Area (MM-GBSA) was also a method that was applied in this study. Daclatasvir showed the highest binding energy and appeared as the best drug to inhibit matrix protein and a fusion protein of RSV. Based on Daclatasvir, 40 computational derivatives were made. D28, D34 and D40 showed far better results than the actual drug. Changes in lipophilicity character increase the binding energy of derivatives. Molecular dynamic simulations showed their non-deviated, non-fluctuated and stable complex formation with target proteins. The high number of amino acid contacts throughout the trajectory increases the stability and effectiveness of derivatives. The key to producing a novel medicine to eradicate RSV is provided by derivatives. Daclatasvir will be employed as a potential RSV inhibitor up until that point.Communicated by Ramaswamy H. Sarma.

Efficacy and Safety of Amenamevir, a Helicase-Primase Inhibitor for the Treatment of Acyclovir-Resistant Herpes Simplex Virus 1 Keratitis

Article

作者: Labetoulle, Marc ; Fernandez, José ; Burrel, Sonia ; Barreau, Emmanuel ; Haigh, Oscar ; Boutolleau, David ; Rousseau, Antoine ; Vauloup-Fellous, Christelle ; Boucher, Rafael

Purpose:The purpose of this study was to describe the efficacy and tolerance of amenamevir (AMNV), an inhibitor of the viral helicase-primase, for the treatment of recalcitrant herpes simplex keratitis (HSK) caused by acyclovir-resistant (ACVR) herpes simplex virus 1 strains.Methods:In this retrospective case series, 6 consecutive patients with HSK caused by an ACVR herpes simplex virus 1 strain with a failure of conventional antiviral therapy were included after having been treated with AMNV (there was no control group of comparable patients for whom previous treatment would have been continued despite its inefficacy). Medical files were assessed for clinical data including reason(s) for AMNV introduction (frequent recurrences despite appropriate preventive antiviral treatment and/or clinical resistance to suppressive antiviral treatment of an ongoing clinical relapse), genotypical resistance to herpes simplex virus 1 documentation, immune status, clinical types and number of HSK episodes before and during AMNV treatment, adverse effects observed during AMNV treatment, and best corrected visual acuity.Results:Of 6 patients, 4 (66%) did not experience a single recurrence during AMNV therapy while 2 others had recurrences (1 over 24 months of treatment and 2 over 23 months, ie two-fold less frequently than with conventional preventive treatment). On the overall history of these 6 patients, AMNV appeared to be associated with a reduction in HSK recurrences, with a mean of only 0.02 ± 0.04 episodes/month during follow-up under AMNV as compared to 0.14 ± 0.04 episodes/month in the year preceding AMNV introduction (P = 0.03). Improvement in vision acuity was also observed (mean best corrected visual acuity 0.17 ± 0.12 logarithm of the minimum angle of resolution at the end of follow-up vs. 0.30 ± 0.35 before AMNV onset), albeit nonsignificant probably due to the limited number of patients (P = 0.38). Neither clinical nor biological adverse effects were observed while under AMNV during the follow-up (16.5 ± 5.8 months).Conclusions:Although there was no control group, AMNV may be a valuable option to reduce ACVR HSK recurrences.

Disproportionality analysis of amenamevir-induced encephalopathy using the Japanese adverse drug event report database

Article

作者: Ashida, Akira ; Ogawa, Taku ; Nishihara, Masami ; Yamada, Tomoyuki ; Kusaka, Yusuke ; Tanaka, Tomoko

INTRODUCTIONAnti-herpesvirus drug-induced encephalopathy can complicate herpes zoster treatment; however, the association between the recently developed anti-herpesvirus drug amenamevir and encephalopathy development remains unknown. Determining the characteristics of amenamevir-induced encephalopathy is essential for potentially improving patient outcomes in the treatment of herpes zoster. The aim of this study is to identify the association between amenamevir treatment and encephalopathy and to determine the risk factors for amenamevir-induced encephalopathy via disproportionality analysis using the Japanese Adverse Drug Event Report (JADER) database.METHODWe conducted a retrospective observational study using anonymized data from the JADER database. Encephalopathy was defined according to the Standardized Medical Dictionary for Regulatory Activities Queries specific to "Noninfectious encephalopathy/delirium." Disproportionality analysis was used to calculate the reporting odds ratios (RORs) and 95 % confidence intervals (CIs) to assess associations between amenamevir and encephalopathy. Multivariable logistic regression considered age, gender, chronic kidney disease, and cytochrome P450 3A inhibitor use as potential risk factors.RESULTSOut of 713,316 patients, 246 were prescribed amenamevir. The median onset of encephalopathy in these patients was 3 days. Disproportionality of encephalopathy was observed in patients treated with amenamevir (ROR, 3.44; 95 % CI, 2.48-4.78). Furthermore, multivariable logistic regression analysis suggested that an age of ≥70 years was associated with amenamevir-induced encephalopathy (ROR, 7.63; 95 % CI, 2.25-25.9).CONCLUSIONThese results suggest that amenamevir treatment may be associated with encephalopathy, particularly in patients aged ≥70 years. Healthcare providers should be aware of this potential risk, especially in elderly patients, to prevent severe central nervous system complications.

Maruho Receives Manufacturing and Marketing Approval for a Partial Change of the Indication and Dosage/Administration for Anti-herpes Virus Agent "Amenalief Tab. 200mg" for the Treatment of Recurrent Herpes Simplex in Japan

Osaka (Japan), February 24, 2023 - Maruho Co., Ltd. ("Maruho", Head Office: Osaka, Japan,President and CEO: Atsushi Sugita) announces that it has received manufacturing and marketing approval from the Ministry of Health, Labor and Welfare for a partial change of the indication and dosage/administration for anti-herpes virus agent "Amenalief® Tab. 200mg" (JAN/INN: amenamevir; hereinafter referred to as "the product") for the treatment of recurrent herpes simplex in Japan. Herpes simplex is a general term for infectious diseases caused by the herpes simplex virus that infects the skin and mucous membranes (lips, eyes, genitals, etc.). Common types include labial herpes and genital herpes. Recurrent herpes simplex is a disease that develops when the herpes simplex virus that has been latently infected in the ganglia after a primary infection, is reactivated by stimuli such as stress or a weakened immune system. Additionally, it is characterized by repeated recurrence of symptoms, and many patients experience discomfort such as itching and tingling before skin symptoms such as erythema (redness), papules and blisters develop. The partial change of the indication and dosage/administration approval received today is recognized as "Patient Initiated Treatment" (PIT) for patients with recurrent herpes simplex when they become aware of the initial symptoms.1) Early treatment is possible by taking the prescribed 1200mg of this drug once after meals within 6 hours after the appearance of the initial symptoms of recurrent herpes simplex. It is hoped that this drug will be more convenient for patients since only one dose is required. Maruho, specializing in dermatology, will strive to further contribute to patients and medical professionals by providing new options for the treatment of recurrent herpes simplex. Note The information contained in this news release in regard to pharmaceutical and developmental products is not intended for the purpose of promotion, advertising or medical advice.

Chemo Drug Potentially More Potent than Remdesivir Against Coronavirus

Researchers with Shenzhen Institutes of Advanced Technology in China used a variety of computational techniques to simulate drug-virus interactions. They then screened 1,906 existing drugs to evaluate which ones might inhibit replication of SARS-CoV-2, the virus that causes COVID-19. From this broad screening, they identified four drugs that had potential to prevent replication of the virus, which they then tested in laboratory experiments. Two of the drugs, pralatrexate, a chemotherapy, and azithromycin, an antibiotic, were successful at preventing replication of the virus. More lab experiments demonstrated that pralatrexate had stronger viral inhibition than Gilead Sciences’ remdesivir, which is currently the only approved drug for COVID-19. They published their research in the journal PLOS Computational Biology. Pralatrexate is marketed by Acrotech Biopharma under the trade name Folotyn. It is indicated for relapsed or refractory peripheral T-cell lymphoma. Like many chemotherapeutics, it comes with a wide range of serious side effects, including low blood cell counts—platelets, white blood cells, and red blood cells—mucositis, which is inflamed mucous membranes, severe skin reactions, tumor lysis syndrome (TLS), increased risk of serious reactions in kidney patients, fever, dehydration, nausea, as well as significant risk for pregnant and nursing women. As a result, the authors note that immediate use of the drug for COVID-19 patients is not guaranteed, but believe their approach was useful in identifying drugs that can be repurposed. “We have demonstrated the value of our novel hybrid approach that combines deep-learning technologies with more traditional simulations of molecular dynamics,” said Haiping Zhang, study author. The research team is working to develop more computational methods for creating novel molecular structures that could be developed into new drugs to treat COVID-19. The screening method focused on viral RNA-dependent RNA polymerase (RdRp), a promising therapeutic target. The authors write that other computational drug screening methods are based on molecular docking, deep learning or Molecular Dynamics. Most of these typically depend upon a single technique or lack experimental validation. “Each computation method,” they write, “with its underlying philosophy, often has its own strong and weak points, while a proper combination and modification of such methods could provide a better solution. Previously, we have developed two deep learning-based models to estimate protein-ligand interactions: DFCNN and DeepBindBC. DFCNN uses molecular vector data of protein pocket and ligand, instead of spatial information at interaction site, to estimate the protein-ligand pair as binding or non-binding with a probability value between 0 and 1. DeepBindBc estimates the binding possibility from atom contact information at interaction surface of a modelled 3D protein-ligand complex. The input of DeepBindBC contains spatial information of the protein-ligand interface, thus it strongly complements DFCNN.” Their hybrid screening procedure was made up of DFCNN, DeepBindBC, Autodoc Vina, pocket localized molecular dynamics simulation, metadynamics, and their own inhouse-developed tools. They screened potential drugs from the TargetMol-Approved_Drug_Library, which contains 1,906 currently marketed drugs. One of the findings, less focused on COVID-19, but of particular interest to validation of the screening approach, was that DFCNN, DeepBindBC and Autodock Vina predicted different drug compounds as top hits. For example, amenamevir and azithromycin had better scores on Autodock Vina, while odanacatib and nitisinone had higher DFCNN scores. Azithromycin, with hydroxychloroquine, an anti-malarial, had demonstrated efficacy in treating COVID-19 earlier in the pandemic, but subsequent studies have failed to show that either drug is effective in treating COVID-19. For that matter, a large World Health Organization (WHO) study failed to prove remdesivir’s effectiveness in hospitalized patients, resulting in the organization issuing a conditional recommendation against its use.
