Expanding the Palette of Molecular Fragments for Small Molecule De Novo Design Through Isosteric Swapping.

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
Outcomes from fragment-based assembly of small organic molecules are highly dependent on the number and type of fragments available for growth. Here, we present a new chemical searching strategy for the DOCK6 de novo design (DOCK_DN) engine which logically expands the palette of available fragments compared to the current method. Termed DOCK_SWAP, the new routine employs principles of isosteric swapping and a customized library infrastructure (iso-libraries) in which topologically related sidechains, linkers, and scaffolds have been pre-aligned and rank ordered relative to a parent fragment (iso-tables). The primary objectives of the current work are: (I) introduce the DOCK_SWAP infrastructure and algorithms, (II) characterize iso-library expansion outcomes and impact of different alignment and ranking protocols, (III) assess search performance, molecular scores, heterogeneity, and growth path coverage and (IV) evaluate lead refinement. Depending on the protocol, the new iso-libraries are roughly an order of magnitude larger (N = 2197 to 2708) than the existing library (N = 382). Large-scale simulations (N = 3420) across 57 protein-ligand systems, using three different iso-libraries each, confirm that the DOCK_SWAP code base and infrastructure is robust. Although the use of larger DOCK_SWAP iso-libraries come at an increased cost in terms of simulation time, the results highlight the many advantages over the existing DOCK_DN method for design of drug-like ligands with improved complementarity to the sites being targeted.
