AI Article Synopsis

  • The study evaluates the effectiveness of six types of 2D fingerprints for scaffold hopping in drug discovery.
  • It finds that 2D fingerprints can successfully identify new scaffolds, with varying success based on the diversity of tested compounds.
  • The extended connectivity fingerprint (ECFP4) is particularly effective for this purpose, highlighting the usefulness of 2D fingerprints in lead discovery.

Article Abstract

Background: It has been suggested that similarity searching using 2D fingerprints may not be suitable for scaffold hopping.

Methods: This article reports a detailed evaluation of the effectiveness of six common types of 2D fingerprints when they are used for scaffold-hopping similarity searches of the Molecular Design Limited Drug Data Report database, World of Molecular Bioactivity database and Maximum Unbiased Validation database.

Results: The results demonstrate that 2D fingerprints can be used for scaffold hopping, with novel scaffolds being identified in nearly every search that was carried out. The degree of enrichment depends on the structural diversity of the actives that are being sought, with the greatest enrichments often being obtained using the extended connectivity fingerprint encoding a circular substructure of diameter four bonds (ECFP4) fingerprint.

Conclusion: 2D fingerprints provide a simple and computationally efficient way of identifying novel chemotypes in lead-discovery programs.

Inflammatory pain represents one of the unmet clinical needs for patients, as conventional therapies cause several side effects. Recently, new targets involved in inflammatory pain modulation have been identified, including the sigma-1 receptor (σ1R). Selective σ1R antagonists have demonstrated analgesic efficacy in acute and chronic inflammatory pain models.

Managing wounds and accompanying consequences like exudation and microbiological infections is challenging in clinical practice. Bioactive compounds from traditional medicinal plants help heal wounds, although their bioavailability is low. This study uses sodium alginate (SA), gelatin (G), and Santalum album oil (SAL) to 3D print a polymeric hydrogel scaffold to circumvent these difficulties.

The cannabinoid receptor 1 (CB1) is an essential component of the endocannabinoid system, responsible for regulating various physiological processes such as pain, mood, and appetite. Despite increasing interest in the therapeutic potential of CB1 modulators, the precise mechanisms by which small molecules modulate receptor activity-particularly without fully transitioning between active and inactive states-remain partially understood. In this study, the complexity of CB1-ligand interactions was evaluated for the inactive CB1 state.

Although small molecule superposition is a standard technique in drug discovery, a rigorous performance assessment of the corresponding methods is currently challenging. Datasets in this field are sparse, small, tailored to specific applications, unavailable, or outdated. The newly developed LOBSTER set described herein offers a publicly available and method-independent dataset for benchmarking and method optimization.
