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

A mutated form of truncated proplasmepsin 1 (proPfPM1) from the human malaria parasite Plasmodium falciparum, proPfPM1 K110pN, was generated and overexpressed in Escherichia coli. The automaturation process was carried out at pH 4.0 and 4.5, and the optimal catalytic pH of the resulting mature PfPM1 was determined to be pH 5.5. This mature PfPM1 showed comparable binding affinity to peptide substrates and inhibitors with the naturally occurring form isolated from parasites. The S3-S3' subsite preferences of the recombinant mature PfPM1 were explored using combinatorial chemistry based peptide libraries. On the basis of the results, a peptidomimetic inhibitor (compound 1) was designed and yielded 5-fold selectivity for binding to PfPM1 versus the homologous human cathepsin D (hcatD). The 2.8 A structure of the PfPM2-compound 1 complex is reported. Modeling studies were conducted using a series of peptidomimetic inhibitors (compounds 1-6, Table 3) and three plasmepsins: the crystal structure of PfPM2, and homology derived models of PfPM1 and PfPM4.
