[Hand, foot and mouth disease--more than a harmless "childhood disease"].
    Medizinische Monatsschrift fur Pharmazeuten, 2014, Volume: 37, Issue:1

    Hand, foot and mouth disease (HFMD) is a highly contagious, world-wide distributed viral illness that affects predominantly children. It is caused by several enteroviruses, such as coxsackieviruses A6, A10, A16 and enterovirus 71. In most cases, HFMD follows a benign and self-limiting course. After an incubation period of 3 to 10 days, fever and sore throat, the first symptoms of the disease, appear. A few days later, maculopapular or vesicular eruptions form on the palms and soles as well as in the oral cavity. Since the year 2000, several large HFMD outbreaks have been reported in many Asian regions such as China, Malaysia and Vietnam. In some of these outbreaks, high incidences of severe progressive HFMD forms with some fatalities were observed. Such diseases have been caused primarily by enterovirus 71 strains and were characterized frequently by sudden onset of fever, encephalitis/meningitis and severe respiratory symptoms such as pulmonary edema. Further severe neurological and cardiac complications have also been observed during these outbreaks. Recently, some HFMD outbreaks caused by the coxsackievirus A6 have been reported in several parts of the world. These illnesses also affected adults and were characterized by more severe symptoms of "classical" HFMD. In addition, outbreaks of coxsackievirus-A6-associated HFMD in many countries were associated with onychomadesis, with the loss of nails occurring up to two months after initial symptoms. Treatment of "classical" HFMD is usually symptomatic, a generally recommended antiviral therapy does not exist. In severe HFMD cases, suitable treatment also encompasses mechanical ventilation, as well as the additional application of antiviral agents such as ribavirin. In the last years, several novel agents with good in vitro and in vivo activity against enteroviruses have been developed. A vaccine against HFMD is not yet available.

Structure of the Enterovirus 71 3C Protease in Complex with NK-1.8k and Indications for the Development of Antienterovirus Protease Inhibitor.
    Antimicrobial agents and chemotherapy, 2017, Volume: 61, Issue:7

    Hand-foot-and-mouth disease (HFMD), caused by enterovirus, is a threat to public health worldwide. To date, enterovirus 71 (EV71) has been one of the major causative agents of HFMD in the Pacific-Asia region, and outbreaks with EV71 cause millions of infections. However, no drug is currently available for clinical therapeutics. In our previous works, we developed a set of protease inhibitors (PIs) targeting the EV71 3C protease (3C

Susceptibility of inhibitors against 3C protease of coxsackievirus A16 and enterovirus A71 causing hand, foot and mouth disease: A molecular dynamics study.
    Biophysical chemistry, 2016, Volume: 219

    Hand foot and mouth disease (HFMD) epidemic has occurred in many countries. Coxsackievirus A16 (CV-A16) and Enterovirus A71 (EV-A71) are the main causes of HFMD. Up to now, there are no anti-HFMD drugs available. Rupintrivir, a broad-spectrum inhibitor, is a drug candidate for HFMD treatment, while other HFMD inhibitors designed from several studies have a relatively low efficiency. Therefore, in this work we aim to study the binding mechanisms of rupintrivir and a peptidic α,β-unsaturated ethyl ester (SG85) against both CV-A16 and EV-A71 3C proteases (3C

Enterovirus 71 and coxsackievirus A16 3C proteases: binding to rupintrivir and their substrates and anti-hand, foot, and mouth disease virus drug design.
    Journal of virology, 2011, Volume: 85, Issue:19

    Enterovirus 71 (EV71) and coxsackievirus A16 (CVA16) are the major causative agents of hand, foot, and mouth disease (HFMD), which is prevalent in Asia. Thus far, there are no prophylactic or therapeutic measures against HFMD. The 3C proteases from EV71 and CVA16 play important roles in viral replication and are therefore ideal drug targets. By using biochemical, mutational, and structural approaches, we broadly characterized both proteases. A series of high-resolution structures of the free or substrate-bound enzymes were solved. These structures, together with our cleavage specificity assay, well explain the marked substrate preferences of both proteases for particular P4, P1, and P1' residue types, as well as the relative malleability of the P2 amino acid. More importantly, the complex structures of EV71 and CVA16 3Cs with rupintrivir, a specific human rhinovirus (HRV) 3C protease inhibitor, were solved. These structures reveal a half-closed S2 subsite and a size-reduced S1' subsite that limit the access of the P1' group of rupintrivir to both enzymes, explaining the reported low inhibition activity of the compound toward EV71 and CVA16. In conclusion, the detailed characterization of both proteases in this study could direct us to a proposal for rational design of EV71/CVA16 3C inhibitors.
