Synthesis and structure-activity relationship studies of tyrosine-based antagonists at the human P2X7 receptor.
Article in Bioorganic & medicinal chemistry letters, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 papers.
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
Analogues of the P2X(7) receptor antagonist KN-62, modified at the piperazine and arylsulfonyl groups, were synthesized and assayed at the human P2X(7) receptor for inhibition of BzATP-induced effects, that is, uptake of a fluorescent dye (ethidium bromide) in stably transfected HEK293 cells and IL-1beta release in differentiated THP-1 cells. Substitution of the arylsulfonyl moiety with a nitro group increased antagonistic potency relative to methyl substitution, such that compound 21 was slightly more potent than KN-62. Substitution with D-tyrosine in 36 and sterically bulky tyrosyl 2,6-dimethyl groups [corrected] in 9 enhanced antagonistic potency.
