Formulation strategies for the development of high drug-loaded amorphous solid dispersions
Drug Discov Today. 2023 Oct 25:103806. doi: 10.1016/j.drudis.2023.103806. Online ahead of print.ABSTRACTAmorphous solid dispersions (ASD) have gained tremendous attention over the past two decades as one of the most promising techniques for enhancing the solubility of poorly water-soluble drugs. However, low drug loading is one of the major challenges of ASD technology that limits its commercialization to only a few drug candidates. Increasing the drug loading increases the risk of recrystallization during storage (solid state) and/or during dissolution (solution state). Various formulation and process-related strategies h...

Illuminating the druggable genome: Pathways to progress
Drug Discov Today. 2023 Oct 25:103805. doi: 10.1016/j.drudis.2023.103805. Online ahead of print.ABSTRACTThere are ∼4500 genes within the 'druggable genome', the subset of the human genome that expresses proteins able to bind drug-like molecules, yet existing drugs only target a few hundred. A substantial subset of druggable proteins are largely uncharacterized or understudied, with many falling within G protein-coupled receptor (GPCR), ion channel, and kinase protein families. To improve scientific understanding of these three understudied protein families, the US National Institutes of Health launched the Illuminating t...

Promising new pharmacological targets for depression: the search for efficacy
Drug Discov Today. 2023 Oct 19:103804. doi: 10.1016/j.drudis.2023.103804. Online ahead of print.ABSTRACTPharmacological treatment of major depressive disorder (MDD) still relies on the use of serotonergic drugs, despite their limited efficacy. A few mechanistically new drugs have been developed in recent years, but many fail in clinical trials. Several hypotheses have been proposed to explain MDD pathophysiology, indicating that physiological processes such as neuroplasticity, circadian rhythms, and metabolism are potential targets. Here, we review the current state of pharmacological treatments for MDD and their problems,...

Anti-amyloid potential of some phytochemicals against A β-peptide and α-synuclein, tau, prion, and Huntington proteins
Drug Discov Today. 2023 Oct 17:103802. doi: 10.1016/j.drudis.2023.103802. Online ahead of print.ABSTRACTSome molecules self-assemble to create complex structures through molecular self-assembly. Hydrogel preparation, tissue repair, and therapeutic drug delivery are a few applications of molecular self-assembly. However, the self-assembly of amino acids, peptides, and proteins forms amyloid fibrils, resulting in various disorders, most notably neurodegenerative ailments. Examples include the self-assembly of phenylalanine, which causes phenylketonuria; Aβ, which causes Alzheimer's disease; the tau protein, which causes bot...

Advances in developing noncovalent small molecules targeting Keap1
Drug Discov Today. 2023 Oct 16:103800. doi: 10.1016/j.drudis.2023.103800. Online ahead of print.ABSTRACTKelch-like ECH-associated protein 1 (Keap1) is a drug target for diseases involving oxidative stress and inflammation. There are three covalent Keap1-binding drugs on the market, but noncovalent compounds that inhibit the interaction between Keap1 and nuclear factor erythroid 2-related factor 2 (Nrf2) represent an attractive alternative. Both compound types prevent degradation of Nrf2, leading to the expression of antioxidant and antiinflammatory proteins. However, their off-target profiles differ as do their exact pharm...
