Molecular binding mode of PF-232798, a clinical anti-HIV candidate, at chemokine receptor CCR5.

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.
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
The chemokine receptor CCR5 is an important anti-HIV (human immunodeficiency virus) drug target owning to its pivotal role in HIV-1 viral entry as a co-receptor. Here, we present a 2.9 Å resolution crystal structure of CCR5 bound to PF-232798, a second-generation oral CCR5 antagonist currently in phase II clinical trials. PF-232798 and the marketed HIV drug maraviroc share a similar tropane scaffold with different amino (N)- and carboxyl (C)- substituents. Comparison of the CCR5-PF-232798 structure with the previously determined structure of CCR5 in complex with maraviroc reveals different binding modes of the two allosteric antagonists and subsequent conformational changes of the receptor. Our results not only offer insights into the phenomenon that PF-232798 has higher affinity and alternative resistance profile to maraviroc, but also will facilitate the design of new anti-HIV drugs.
