Abstract
INTRODUCTION Influenza affects individuals of all ages and poses a significant threat during pandemics, epidemics, and sporadic outbreaks. Neuraminidase inhibitors (NAIs) are currently the first choice in the treatment and prevention of influenza, but their use can be hindered by viral resistance. AREAS COVERED This review summarizes current NAIs pharmacological profiles, their current place in therapy, and the mechanisms of viral resistance and outlines possible new indications, ways of administration, and novel candidate NAIs compounds. EXPERT OPINION NAIs represent a versatile group of compounds with diverse administration methods and pharmacokinetics. While the prevalence of influenza virus resistance to NAIs remains low, there is heightened vigilance due to the pandemic potential of influenza. Several novel NAIs and derivatives are currently under assessment at various stages of development for the treatment and prevention of influenza.

Abstract
The influenza virus remains a major health concern for mankind because it tends to mutate frequently and cause high morbidity. Influenza prevention and treatment are greatly aided by the use of antivirals. One such class of antivirals is neuraminidase inhibitors (NAIs), effective against influenza viruses. A neuraminidase on the virus's surface serves a vital function in viral propogation by assisting in the release of viruses from infected host cells. Neuraminidase inhibitors are the backbone in stoping such virus propagation thus helps in the treatment of influenza viruses infections. Two NAI medicines are licensed globally: Oseltamivir (Tamiflu™) and Zanamivir (Relanza™). There are two molecules that have acquired Japanese approval recently: Peramivir and Laninamivir, whereas Laninamivir octanoate is in Phase III clinical trials. The need for novel NAIs is due to frequent mutations in viruses and the rise in resistance against existing medication. The NA inhibitors (NAIs) are designed to have (oxa)cyclohexene scaffolds (a sugar scaffold) to mimic the oxonium transition state in the enzymatic cleavage of sialic acid. This review discusses in details and comprises all such conformationally locked (oxa)cyclohexene scaffolds and their analogues which have been recently designed and synthesized as potential neuraminidase inhibitors, thus as antiviral molecules. The structure-activity relationship of such diverese molecules has also been discussed in this review.

Abstract
With our continuous endeavors in seeking neuraminidase (NA) inhibitors, we reported herein three series of novel oseltamivir amino derivatives with the goal of exploring the druggable chemical space inside the 150-cavity of influenza virus NAs. Among them, around half of the compounds in series C were demonstrated to be better inhibitors against both wild-type and oseltamivir-resistant group-1 NAs than oseltamivir carboxylate (OSC). Notably, compounds 12d, 12e, 15e, and 15i showed more potent or equipotent antiviral activity against H1N1, H5N1, and H5N8 viruses compared to OSC in cellular assays. Furthermore, compounds 12e and 15e exhibited high metabolic stability in human liver microsomes (HLMs) and low inhibitory effect on main cytochrome P450 (CYP) enzymes, as well as low acute/subacute toxicity and certain antiviral efficacy in vivo. Also, pharmacokinetic (PK) and molecular docking studies were performed. Overall, 12e and 15e possess great potential to serve as anti-influenza candidates and are worthy of further investigation.

Abstract
Depending on the strain, influenza A virus causes animal, zoonotic, pandemic, or seasonal influenza with varying degrees of severity. Two surface glycoprotein spikes, hemagglutinin (HA) and neuraminidase (NA), are the most important influenza A virus antigens. NA plays an important role in the propagation of influenza virus by removing terminal sialic acid from sialyl decoy receptors and thereby facilitating the release of viruses from traps such as in mucus and on infected cells. Some NA inhibitors have become widely used drugs for treatment of influenza. However, attempts to develop effective and safe NA inhibitors that can be used for treatment of anti-NA drugs-resistant influenza viruses have continued. In this chapter, we describe the following updates on influenza A NA inhibitor development: (i) N-acetylneuraminic acid (Neu5Ac)-based derivatives, (ii) covalent NA inhibitors, (iii) sulfo-sialic acid analogs, (iv) N-acetyl-6-sulfo-β-D-glucosaminide-based inhibitors, (v) inhibitors targeting the 150-loop of group 1 NAs, (vi) conjugation inhibitors, (vii) acylhydrazone derivatives, (viii) monoclonal antibodies, (ix) PVP-I, and (x) natural products. Finally, we provide future perspectives on the next-generation anti-NA drugs.

Abstract
The root of Isatis indigotica is used as a traditional Chinese medicine (termed Isatidis Radix) due to its antiviral effects. We examined compounds isolated from Isatidis Radix and elucidated the structures of three new natural alkaloids, and we examined the possible mechanisms or active targets of indole alkaloids occurring in blood of rats treated by gavage. Three new natural products were isolated from Radix Isatidis for the first time, including 1-methoxy-2-indoleacetonitrile, 1-hydroxy-3-indoleacetonitrile, 8-Methoxy-1, 2-dihydroquinoline, and 4 compounds isolated from this medicinal material for the first time. Their structures were elucidated using nuclear magnetic resonance. The components of Isatidis Radix were analysed using liquid chromatography tandem mass spectrometry, and 33 compounds were detected in plasma of treated rats; 24 of these compounds were indole alkaloids, and they included the newly identified compounds. Molecular docking and in vitro antithrombin activity tests showed HA inhibition activity of indoleacetonitriles.

Abstract
Resistant viruses containing mutant neuraminidases (NAs) with diminished drug affinity continue to emerge, and new anti-influenza agents are urgently required. Several potent inhibitors targeting the hydrophobic 150-cavity of viral NAs have been developed by modifying the antiviral drugs, oseltamivir carboxylate (OSC) and zanamivir, with hydrophobic groups. Here, we describe a different strategy for exploring novel and efficient NA inhibitors by targeting the charged amino acid residues around the entrance to the 150-cavity. We synthesized a C5-substituted OSC derivative (1e) with a 4'-phenyl-1,2,3-triazolyl group capable of entering the 150-cavity, and solved the crystal structure of 1e in complex with influenza A virus N5 NA. Using the resulting structural information, we next designed and synthesized two series of OSC derivatives carrying various polar substituents at the triazolyl group of 1e and 2e, with 2e being a 5'-phenyl-1,2,3-triazole regioisomer of 1e. The NA inhibition assays demonstrated that the 2 series (2e-n) generally had superior activity compared with the 1 series (1e-n). Compound 2j, bearing a 3-phenylamino group on the triazole ring, was the most potent inhibitor of all tested NAs including an N2 NA containing the E119V OSC-resistant mutation. Moreover, 2j potently inhibited viral replication in vitro, and molecular docking studies revealed that its phenylamino group can form an additional strong hydrogen bond with residue D151 near the entrance of the 150-cavity. The design method described in this study provides useful insights into the development of novel NA inhibitors. Compound 2j warrants further structural optimization to obtain a candidate for clinical use.

Abstract
Penicillium polonicum MCCC3A00951 is a fungus with influenza neuraminidase (NA) inhibition activity derived from a sediment of the mangrove forest of Zhangjiangkou in Fujian province, China. Chemical investigation on an ethyl acetate extract of its fermentation led to the isolation of a new compound, 7-hydroxy-3,10-dehydrocyclopeptine (1), and 13 known compounds (2-14). The new compound was comprehensively characterised by high-resolution electrospray ionisation-mass spectrometry, and 1D, 2D nuclear magnetic resonance (NMR) spectra. The anti-influenza NA assay was performed to evaluate the potential biological activity. Surprisingly, Cyclopenin (2) showed potent influenza NA inhibition with an IC50 value of 5.02 μM. Besides, molecular docking simulation was performed to investigate the binding model of cyclopenin (2) with influenza NA. Consequently, cyclopenin (2) could be further optimised to be a potential anti-influenza NA candidate.
