Targeting SARS-CoV-2 Structural and Accessory Proteins: Emerging Opportunities for Small-Molecule Coronavirus Antivirals.
Review in Pharmaceutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Although antiviral development against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been dominated by replication-directed strategies, structural and accessory proteins offer a complementary and increasingly important opportunity for small-molecule intervention. These proteins control key processes outside the core replication machinery, including viral entry, membrane remodelling, virion assembly, egress, and host immune modulation, thereby expanding the mechanistic scope of antiviral design. However, many of these targets are membrane-associated, oligomeric, conformationally dynamic, or function through protein-protein interactions, creating distinct challenges in target validation, assay design, and chemical optimisation. In this review, we comprehensively and critically evaluate the structural and accessory proteomes of SARS-CoV-2, with a strict focus on small-molecule tractability and translational relevance. We highlight the most credible direct-acting opportunities, focusing on the membrane (M), envelope (E), and nucleocapsid (N) structural proteins, together with the accessory protein open reading frame 3a (ORF3a), for which emerging chemical matter strengthens confidence in druggability. In contrast, Spike (S) and several host-interface accessory proteins, including ORF6, ORF8, ORF9b, and ORF10, are best viewed as more selective or earlier-stage opportunities that require stronger on-target chemical validation. Emphasis is placed on structural accessibility, mechanism-based assay systems, evidence quality, cellular and in vivo activity, and developability constraints relevant to exposure at the infection site. Rather than replacing replication-directed antivirals, these non-canonical targets are best considered adjunctive or complementary components of future combination strategies designed to broaden antiviral coverage, enhance robustness, and improve pandemic preparedness.
