Dimers of isatin derived α-methylene-γ-butyrolactone as potent anti-cancer agents.
Article in Bioorganic & medicinal chemistry letters, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
The IKK-NFκB complex is a key signaling node that facilitates activation of gene expression in response to extracellular signals. The kinase IKKβ and the transcription factor RELA have been targeted by covalent modifiers that bind to surface exposed cysteine residues. A common feature in well characterized covalent modifiers of RELA and IKKβ is the Michael acceptor containing α-methylene-γ-butyrolactone functionality. Through synthesis and evaluation of a focused set of α-methylene-γ-butyrolactone containing spirocyclic dimers (SpiDs) we identified SpiD3 as an anticancer agent with low nanomolar potency. Using cell-free and cell-based studies we show that SpiD3 is a covalent modifier that generates stable RELA containing high molecular weight complexes. SpiD3 inhibits TNFα-induced IκBα phosphorylation resulting in the blockade of RELA nuclear translocation. SpiD3 induces apoptosis, inhibits colony formation and migration of cancer cells. The NCI-60 cell line screen revealed that SpiD3 potently inhibits growth of leukemia cell lines, making it a suitable pre-therapeutic lead for hematological malignancies.
