Опубликована: Апрель 11, 2024

Cancer persists as a global challenge necessitating continual innovation in treatment strategies. Despite significant advancements comprehending the disease, cancer remains leading cause of mortality worldwide, exerting substantial economic burdens on healthcare systems and societies. The emergence drug resistance further complicates therapeutic efficacy, underscoring urgent need for alternative approaches. Drug repurposing, characterized by utilization existing drugs novel clinical applications, emerges promising avenue addressing these challenges. Repurposed drugs, comprising FDA-approved (in other disease indications), generic, off-patent, failed medications, offer distinct advantages including established safety profiles, cost-effectiveness, expedited development timelines compared to discovery processes. Various methodologies, such knowledge-based analyses, drug-centric strategies, computational approaches, play pivotal roles identifying potential candidates repurposing. However, despite promise repurposed repositioning confronts formidable obstacles. Patenting issues, financial constraints associated with conducting extensive trials, necessity combination therapies overcome limitations monotherapy pose This review provides an in-depth exploration covering diverse array approaches experimental, re-engineering protein, nanotechnology, methods.

Influenza is an acute respiratory infection caused by influenza viruses (IFV), According to the World Health Organization (WHO), seasonal IFV epidemics result in approximately 3–5 million cases of severe illness, leading about half a deaths worldwide, along with economic losses and social burdens. Unfortunately, frequent mutations lead certain lag vaccine development as well resistance existing antiviral drugs. Therefore, it great importance develop anti-IFV drugs high efficiency against wild-type resistant strains, needed fight current future outbreaks different strains. In this review, we summarize general strategies used for discovery agents targeting multiple strains (including those available drugs). Structure-based drug design, mechanism-based multivalent interaction-based design repurposing are amongst most relevant that provide framework IFV.

Artificial Intelligence/Machine Learning-Driven Small Molecule Repurposing via Off-Target Prediction and Transcriptomics

Toxics, Год журнала: 2023, Номер 11(10), С. 875 - 875

Опубликована: Окт. 22, 2023

The process of discovering small molecule drugs involves screening numerous compounds and optimizing the most promising ones, both in vitro vivo. However, approximately 90% these optimized candidates fail during trials due to unexpected toxicity or insufficient efficacy. Current concepts with respect drug–protein interactions suggest that each interacts an average 6–11 targets. This implies approved even discontinued could be repurposed by leveraging their unintended Therefore, we developed a computational repurposing framework for molecules, which combines artificial intelligence/machine learning (AI/ML)-based chemical similarity-based target prediction methods cross-species transcriptomics information. methodology incorporates eight distinct methods, including three machine methods. By using multiple orthogonal “dataset” composed 2766 FDA-approved targeting therapeutic classes, identified 27,371 off-target involving 2013 protein targets (i.e., around 10 per drug). Relative dataset, 150,620 structurally similar compounds. highest number predicted were G protein-coupled receptors (GPCRs), enzymes, kinases 10,648, 4081, 3678 interactions, respectively.

Reversal gene expression assessment for drug repurposing, a case study of glioblastoma

Journal of Translational Medicine, Год журнала: 2025, Номер 23(1)

Опубликована: Янв. 7, 2025

Abstract Background Glioblastoma (GBM) is a rare brain cancer with an exceptionally high mortality rate, which illustrates the pressing demand for more effective therapeutic options. Despite considerable research efforts on GBM, its underlying biological mechanisms remain unclear. Furthermore, none of United States Food and Drug Administration (FDA) approved drugs used GBM deliver satisfactory survival improvement. Methods This study presents novel computational pipeline by utilizing gene expression data analysis drug repurposing to address challenges in disease development, particularly focusing GBM. The Gene Expression Profile (GGEP) was constructed multi-omics identify reversal GGEP from Integrated Network-Based Cellular Signatures (iLINCS) database. Results We prioritized candidates via hierarchical clustering their signatures quantification strength calculating two self-defined indices based genes’ log2 foldchange (LFC) that could induce. Among five candidates, in-vitro experiments validated Clofarabine Ciclopirox as highly efficacious selectively targeting cells. Conclusions success this illustrated promising avenue accelerating development uncovering effect between diseases, can be extended other diseases non-rare diseases.
