Targeting Mycobacterium tuberculosis Sensitivity to Thiol Stress at Acidic pH Kills the Bacterium and Potentiates Antibiotics.
Article in Cell chemical biology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 43 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
Mycobacterium tuberculosis (Mtb) must sense and adapt to immune pressures such as acidic pH during pathogenesis. The goal of this study was to isolate compounds that inhibit acidic pH resistance, thus defining virulence pathways that are vulnerable to chemotherapy. Here, we report that the compound AC2P36 selectively kills Mtb at acidic pH and potentiates the bactericidal activity of isoniazid, clofazimine, and diamide. We show that AC2P36 activity is associated with thiol stress and causes an enhanced accumulation of intracellular reactive oxygen species at acidic pH. Mechanism of action studies demonstrate that AC2P36 directly depletes Mtb thiol pools, with enhanced depletion of free thiols at acidic pH. These findings support that Mtb is especially vulnerable to thiol stress at acidic pH and that chemical depletion of thiol pools is a promising target to promote Mtb killing and potentiation of antimicrobials.
