Chen Y, Li Y, Lu L, Zou P. Zafirlukast, as a viral inactivator, potently inhibits infection of several flaviviruses, including Zika virus, dengue virus, and yellow fever virus. Antimicrob Agents Chemother 2024; 68:e0016824. [PMID: 38809067 PMCID: PMC11232407 DOI: 10.1128/aac.00168-24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 05/02/2024] [Indexed: 05/30/2024] Open
Abstract
Zika virus (ZIKV) is one of the mosquito-borne flaviviruses that exhibits a unique tropism to nervous systems and is associated with Guillain-Barre syndrome and congenital Zika syndrome (CZS). Dengue virus (DENV) and yellow fever virus (YFV), the other two mosquito-borne flaviviruses, have also been circulating for a long time and cause severe diseases, such as dengue hemorrhagic fever and yellow fever, respectively. However, there are no safe and effective antiviral drugs approved for the treatment of infections or coinfections of these flaviviruses. Here, we found that zafirlukast, a pregnancy-safe leukotriene receptor antagonist, exhibited potent antiviral activity against infections of ZIKV strains from different lineages in different cell lines, as well as against infections of DENV-2 and YFV 17D. Mechanistic studies demonstrated that zafirlukast directly and irreversibly inactivated these flaviviruses by disrupting the integrity of the virions, leading to the loss of viral infectivity, hence inhibiting the entry step of virus infection. Considering its efficacy against flaviviruses, its safety for pregnant women, and its neuroprotective effect, zafirlukast is a promising candidate for prophylaxis and treatment of infections or coinfections of ZIKV, DENV, and YFV, even in pregnant women.

Abstract
Different from most antiretroviral drugs that act as passive defenders to inhibit HIV-1 replication inside the host cell, virus inactivators can attack and inactivate HIV-1 virions without relying on their replication cycle. Herein, we describe the discovery of a hydrocarbon double-stapled helix peptide, termed D26. D26 is based on the HIV-1 gp41 protein lentiviral lytic peptide-3 motif (LLP3) sequence, which can efficiently inhibit HIV-1 infection and inactivate cell-free HIV-1 virions. It was noted that D26 was highly resistant to proteolytic degradation and exhibited a remarkably extended in vivo elimination half-life. Additionally, relative to its linear, nonstapled version, D26 exhibited much higher exposure in sanctuary sites for HIV-1. Amazingly, this lead compound also demonstrated detectable oral absorption. Thus, it can be concluded that D26 is a promising candidate for further development as a long-acting, orally applicable HIV-1 inactivator for the treatment of HIV-1 infection.

Abstract
The discovery of anti-retroviral (ARV) drugs over the past 36 years has introduced various classes, including nucleoside/nucleotide reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitor, fusion, and integrase strand transfer inhibitors inhibitors. The introduction of combined highly active anti-retroviral therapies in 1996 was later proven to combat further ARV drug resistance along with enhancing human immunodeficiency virus (HIV) suppression. As though the development of ARV therapies was continuously expanding, the variation of action caused by ARV drugs, along with its current updates, was not comprehensively discussed, particularly for HIV-1 infection. Thus, a range of HIV-1 ARV medications is covered in this review, including new developments in ARV therapy based on the drug's mechanism of action, the challenges related to HIV-1, and the need for combination therapy. Optimistically, this article will consolidate the overall updates of HIV-1 ARV treatments and conclude the significance of HIV-1-related pharmacotherapy research to combat the global threat of HIV infection.

New 2-alkylthio-1-benzylimidazole-5-carboxylic acid derivatives targeting gp41: design, synthesis and in vitro anti-HIV activity evaluation. Curr HIV Res 2022; 20:CHR-EPUB-124859.

Abstract
Background Although current available medications have increased the quality of life in HIV-infected patients, there are still some shortcomings in HIV treatment arising from viral resistance, drug side effects and high cost of medication. Therefore, there is an urgent need for some suitable HIV inhibitors with different mechanisms of action. Gp41, located on the HIV cell surface, plays an important role in the fusion of viral and host cell membranes. With the same structure in different HIV strains, gp41 seems to be a promising target for developing novel HIV fusion inhibitors. Objective Based on the essential structural elements of gp41 inhibitors, two series of compounds were prepared and their inhibitory effect on HIV cell growth was investigated. Compared to the known small-molecule gp41 inhibitors, 2-Alkylthio-1-benzylimidazole-5-carboxylic acid (series I) and (E)-4-{[5-(((1-benzyl-1H-1,2,3-triazol-4-yl)methoxyimino)methyl)-2-(alkylthio)-1H-imidazol-1-yl]methyl}benzoic acid derivatives (series II) had more flexible skeleton with extra moieties interacting with the gp41 key residues. Method In silico drug design approaches including molecular docking and molecular dynamics simulations were employed to design these novel compounds prior to preparation. The designed compounds exhibited proper chemical interactions and stable complexes with gp41. Then, the selected candidates were efficiently synthesized, and their anti-HIV-1 and anti-HIV-2 activities, as well as their cellular cytotoxicity in MT-4 cells were determined. Results None of the compounds belonging to the series I were active against HIV-1 and HIV-2 replication in cell cultures, and most of the compounds in series II exhibited significant cytotoxicity against MT-4 cells in low micro molar concentrations. Conclusion The smaller molecular structures of the compounds in series I might be responsible for their poor anti-HIV effects. The high toxicity of the series II compounds on the host cell makes it impossible to assess their anti-HIV activities.

Abstract
Highly active antiretroviral therapy currently used for HIV/AIDS has significantly increased the life expectancy of HIV-infected individuals. It has also improved the quality of life, reduced mortality, and decreased the incidence of AIDS and HIV-related conditions. Currently, however, affected individuals are typically on a lifetime course of several therapeutic drugs, all with the potential for associated toxicity and emergence of resistance. This calls for development of novel, potent, and broad anti-HIV agents able to stop the spread of HIV/AIDS. Significant progress has been made toward identification of anti-HIV-1 broadly neutralizing antibodies (bNAbs). However, antibody-based drugs are costly to produce and store. Administration (by injection only) and other obstacles limit clinical use. In recent years, several highly promising small-molecule HIV-1 entry inhibitors targeting the epitopes of bNAbs have been developed. These newly developed compounds are the focus of the present article.

Abstract
Antiretroviral drugs employed for the treatment of human immunodeficiency virus (HIV) infections have remained largely ineffective due to their poor bioavailability, numerous adverse effects, modest uptake in infected cells, undesirable drug-drug interactions, the necessity for long-term drug therapy, and lack of access to tissues and reservoirs. Nanotechnology-based interventions could serve to overcome several of these disadvantages and thereby improve the therapeutic efficacy of antiretrovirals while reducing the morbidity and mortality due to the disease. However, attempts to use nanocarriers for the delivery of anti-retroviral drugs have started gaining momentum only in the past decade. This review explores in-depth the various nanocarriers that have been employed for the treatment of HIV infections highlighting their merits and possible demerits.

Abstract
In recent years, infectious diseases caused by viral infections have seriously endangered human health, especially COVID-19, caused by SARS-CoV-2, which continues to spread worldwide. The development of broad-spectrum antiviral inhibitors is urgently needed. Here, we report a series of small-molecule compounds that proved effective against human coronaviruses (HCoV), such as SARS-CoV-2 and its variants of concern (VOCs), including Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1), Delta (B.1.617.2), and Omicron (B.1.1.529), SARS-CoV, MERS-CoV, HCoV-OC43, and other viruses with class I viral fusion proteins, such as influenza virus, Ebola virus (EBOV), Nipah virus (NiV), and Lassa fever virus (LASV). They are also effective against class II enveloped viruses represented by ZIKV and class III enveloped viruses represented by vesicular stomatitis virus (VSV). Further studies have shown that these compounds may exert antiviral effects through a variety of mechanisms, including inhibiting the formation of the six-helix bundle, which is a typical feature of enveloped virus fusion with cell membranes, and/or targeting viral membrane to inactivate cell-free virions. These compounds are expected to become drug candidates against SARS-CoV-2 and other enveloped viruses.

Recent research results have converted gp120 binders to a therapeutic option for the treatment of HIV-1 infection. A medicinal chemistry point of view. Eur J Med Chem 2021; 229:114078.

Abstract
Current therapeutic armamentarium for treatment of HIV-1 infection is based on the use of highly active antiretroviral therapy that, unfortunately, does not act as a curative remedy. Moreover, duration of the therapy often results in lack of compliance with the consequent emergence of multidrug resistance. Finally, drug toxicity issues also arise during treatments. In the attempt to achieve a curative effect, in addition to invest substantial resources in finding new anti-HIV-1 agents and in optimizing antiviral lead compounds and drugs currently available, additional efforts should be done to deplete viral reservoir located within host CD4+ T cells. Gp120 binders represent a class of compounds able to affect the interactions between viral envelope proteins and host CD4, thus avoiding virus-to-cell attachment and fusion, and the consequent viral entry into host cells. This review summarizes the efforts done in the last five years to design new gp120 binders, that finally culminated in the approval of fostemsavir as an anti-HIV-1 drug.
