The Druggable Transcriptome Project: From Chemical Probes to Precision Medicines

Biochemistry, Год журнала: 2025, Номер unknown

Опубликована: Март 25, 2025

RNA presents abundant opportunities as a drug target, offering significant potential for small molecule medicine development. The transcriptome, comprising both coding and noncoding RNAs, is rich area therapeutic innovation, yet challenges persist in targeting with molecules. structure can be predicted or without experimental data, but discrepancies the actual biological impede progress. Prioritizing targets supported by genetic evolutionary evidence enhances success. Further, molecules must demonstrate binding to cells, not solely vitro, validate target compound. Effective binders modulate functional sites that influence biology, nonfunctional requires recruiting effector mechanisms, example degradation, achieve outcomes. Addressing these critical unlocking RNA's vast medicines, strategic framework proposed navigate this promising field, focus on human RNAs.

Target Engagement Assays in Early Drug Discovery

Journal of Medicinal Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Июнь 4, 2025

In target-based drug discovery, quantification of target engagement is required to build structure-activity relationships and develop a potent clinical candidate. Target data also provides evidence drug's mechanism action (MoA) which although not for approval, can increase the chance successful outcome. Consequently, plethora assays has been developed provide information about on isolated proteins in cells. These techniques monitor changes stability, structure, optical properties or mass difference between their complexes with ligands. They characterization compound thermodynamic, kinetic structural binding parameters. The diversity approaches reflects challenges faced when drugging different protein classes, each method having advantages, trade-offs specificity.

Investigating Active Site Binding of Ligands to High and Low Activity Carbonic Anhydrase Enzymes Using Native Mass Spectrometry

Journal of Medicinal Chemistry, Год журнала: 2024, Номер 67(17), С. 15862 - 15872

Carbonic anhydrases (CAs) are a family of enzymes that play an important pH regulatory role in health and disease. While different CA isozymes have high degree structural similarity, they variable enzymatic activity, with III being the least active having less than 1% activity II, most active. Furthermore, ligand binding studies for limited, resulting lack chemical probes impedes understanding this isozyme comparison to other members where abundant. Therefore, we employed native mass spectrometry (nMS), also known as intact spectrometry, assess II discovered two novel compounds first time display strong III. We present new data visualization quantification tool developed spectra intuitive stacked heat map representation rapidly interpreting results ligand-protein from nMS screening.
