چکیده

The present study aims to clarify the inhibitive effect of the compounds from Rheum palmatum L. on the SARS-3CL protease. The SARS-CoV 3CL gene was amplified from RNA of the SARS virus by PCR. The SARS-CoV 3CL protease was purified from a colon bacillus recombinant. Drugs and 3CL protease were incubated together. The inhibition rate and IC(50) were calculated based on absorbance. Components from the Rheum palmatum L. had a high level of anti-SARS-CoV 3CL protease activity. The IC(50) was 13.76 +/- 0.03 microg/mL and the inhibition rate was up to 96%. In conclusion, extracts from Rheum palmatum L. have a high level of inhibitory activity against 3CL protease, suggesting that extracts from Rheum palmatum L. may represent a potential therapeutic for SARS.

Structural basis of mercury- and zinc-conjugated complexes as SARS-CoV 3C-like protease inhibitors.

Five active metal-conjugated inhibitors (PMA, TDT, EPDTC, JMF1586 and JMF1600) bound with the 3C-like protease of severe acute respiratory syndrome (SARS)-associated coronavirus were analyzed crystallographically. The complex structures reveal two major inhibition modes: Hg(2+)-PMA is coordinated to C(44), M(49) and Y(54) with a square planar geometry at the S3 pocket, whereas each Zn(2+) of th...

Exploring the binding mechanism of the main proteinase in SARS-associated coronavirus and its implication to anti-SARS drug design.

The main proteinase of SARS-associated coronavirus (SARS-CoV) plays an important role in viral transcription and replication, and is an attractive target for anti-SARS drug development. The important thing is to understand its binding mechanism with possible ligands. In this study, we investigated possible noncanonical interactions, potential inhibitors, and binding pockets in the main proteina...

Characterization and Inhibition of the Main Protease of Severe Acute Respiratory Syndrome Coronavirus

The main protease of SARS-associated coronavirus (SARS-CoV), also called 3C-like protease (3CL), is vital for the viral replication. It cleaves the replicase polyproteins at 11 sites and is a promising drug target. Several groups of inhibitors have been identified through high-throughput screening and rational drug design. In addition to the pharmaceutical applications, a mutant 3CL (T25G) with...

Recent 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...

Mechanism for controlling the dimer-monomer switch and coupling dimerization to catalysis of the severe acute respiratory syndrome coronavirus 3C-like protease.

Unlike 3C protease, the severe acute respiratory syndrome coronavirus (SARS-CoV) 3C-like protease (3CLpro) is only enzymatically active as a homodimer and its catalysis is under extensive regulation by the unique extra domain. Despite intense studies, two puzzles still remain: (i) how the dimer-monomer switch is controlled and (ii) why dimerization is absolutely required for catalysis. Here we ...
