Advances in research on pharmacological mechanisms of anatabine: from nicotinic modulation to multitarget therapeutic potential.
Review in Experimental biology and medicine (Maywood, N.J.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Anatabine, a characteristic minor alkaloid derived from tobacco byproducts, exhibits unique structural analogy to nicotine but possesses a superior safety profile and lower addictive liability, rendering it a promising natural multi-target therapeutic candidate. Accumulating preclinical evidence has demonstrated that anatabine exerts neuroprotective, anti-inflammatory, and antioxidant effects mainly through modulating α7/α4β2 nicotinic acetylcholine receptors, suppressing NF-κB/STAT3 inflammatory signaling, and activating the Nrf2-mediated antioxidant pathway. It effectively ameliorates typical pathological alterations, including β-amyloid deposition, tau hyperphosphorylation, and microglial overactivation, thereby improving cognitive and behavioral deficits in neurodegenerative disease models. Additionally, anatabine displays broad pharmacological potentials in chronic inflammation, autoimmune thyroiditis, asthma, and hypertension. Differing from previous reviews that merely focused on single receptor regulation, the present work systematically summarizes the multi-target pharmacological characteristics of anatabine, comprehensively collates its preclinical efficacy across multiple disease categories, and highlights its advantages over nicotine in safety and addiction risk. Furthermore, we analyze the current limitations, druggability optimization challenges, and clinical translation prospects, and propose sustainable strategies for high-value utilization of tobacco byproducts. This review provides an updated and systematic theoretical basis for further mechanism exploration and therapeutic development of anatabine.
