Synthesis and evaluation of isatin derivatives as effective SARS coronavirus 3CL protease inhibitors.
N-Substituted isatin derivatives were prepared from the reaction of isatin and various bromides via two steps. Bioactivity assay results (in vitro tests) demonstrated that some of these compounds are potent and selective inhibitors against SARS coronavirus 3CL protease with IC50 values ranging from 0.95 to 17.50 microM. Additionally, isatin 4o exhibited more potent inhibition for SARS coronavir...
متن کاملDesign and synthesis of cinanserin analogs as severe acute respiratory syndrome coronavirus 3CL protease inhibitors.
The severe acute respiratory syndrome (SARS) coronavirus 3CL protease is an attractive target for the development of anti-SARS drugs. In this paper, cinanserin (1) analogs were synthesized and tested for the inhibitory activities against SARS-coronavirus (CoV) 3CL protease by fluorescence resonance energy transfer (FRET) assay. Four analogs show significant activities, especially compound 26 wi...
متن کاملRecent development of 3C and 3CL protease inhibitors for anti-coronavirus and anti-picornavirus drug discovery.
SARS-CoV (severe acute respiratory syndrome-associated coronavirus) caused infection of ~8000 people and death of ~800 patients around the world during the 2003 outbreak. In addition, picornaviruses such as enterovirus, coxsackievirus and rhinovirus also can cause life-threatening diseases. Replication of picornaviruses and coronaviruses requires 3Cpro (3C protease) and 3CLpro (3C-like protease...
متن کاملStudy on substrate specificity at subsites for severe acute respiratory syndrome coronavirus 3CL protease.
Autocleavage assay and peptide-based cleavage assay were used to study the substrate specificity of 3CL protease from the severe acute respiratory syndrome coronavirus. It was found that the recognition between the enzyme and its substrates involved many positions in the substrate, at least including residues from P4 to P2'. The deletion of either P4 or P2' residue in the substrate would decrea...
متن کاملThe nutritional significance of plant protease inhibitors.
It has been recognized for many years that the nutritive value and protein digestibility of many plant proteins, particularly those derived from legumes, are very poor unless subjected to cooking or some other form of heat treatment (Liener & Kakade, 1969). This beneficial effect of heat has beem generally attributed, at least in part, to the destruction of a unique class of proteins which have...
