1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundThe coronavirus 3 chymotrypsin-like protease (3CL(pro)) is a validated target in the design of potential anticoronavirus inhibitors. The high degree of homology within the protease's active site and substrate conservation supports the identification of broad spectrum lead compounds. A previous study identified the compound ML188, also termed 16R, as an inhibitor of the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) 3CL(pro). This study will detail the generation of a homology model of the 3CL(pro) of the human coronavirus OC43 and determine the potential of 16R to form a broad-spectrum lead compound. MODELLER was used to generate a suitable three-dimensional model of the OC43 3CL(pro) and the Prime module of Schrӧdinger predicted the binding conformation and free energy of binding of 16R within the 3CL(pro) active site. Molecular dynamics further confirmed ligand stability and hydrogen bonding networks.

resultsA high quality homology model of the OC43 3CL(pro) was successfully generated in an active conformation. Further studies reproduced the binding pose of 16R within the active site of the generated model, where its free energy of binding was shown to equal that of the 3CL(pro) of SARS-CoV, a receptor it is experimentally proven to inhibit. The stability of the ligand was subsequently confirmed by molecular dynamics.

conclusionThe lead compound 16R may represent a broad-spectrum inhibitor of the 3CL(pro) of OC43 and potentially other coronaviruses. This study provides an atomistic structure of the 3CL(pro) of OC43 and supports further experimental validation of the inhibitory effects of 16R. These findings further confirm that the 3CL(pro) of coronaviruses can be inhibited by broad spectrum lead compounds.
