Traditional Drug Discovery Methods
Traditional drug discovery methods have long been the cornerstone of pharmaceutical research and development.These methods typically rely on a series of experimental approaches and empirical observations to identify potential drug candidates.While these techniques have led to numerous successful therapies, they suffer from inherent limitations and challenges that impede the efficient and timely discovery of new drugs.Traditional drug discovery methods encompass a range of strategies, including high-throughput screening, target-based approaches, and natural product discovery.

High-Throughput Screening
High-throughput screening (HTS) is a widely used traditional drug discovery method that involves testing large libraries of compounds against specific biological targets or assays [4].HTS allows for the rapid screening of thousands to millions of compounds to identify potential drug leads.It involves several key steps, including compound library preparation and assay development.HTS requires a diverse and representative collection of compounds known as a compound library [5].These libraries can consist of thousands to millions of small molecules or natural product extracts.The compounds in the library are typically selected based on their structural diversity, drug-likeness properties, and commercial availability.Compound libraries can be sourced from various vendors, synthesized in-house, or derived from natural product extracts [5].In comparison, assay development involves designing and optimizing a robust biological or biochemical assay that allows the measurement of a specific target or activity relevant to the disease or condition of interest [4,5].The choice of the assay depends on the target and the intended mode of action of the drug.Assays can range from enzyme-based assays, receptor-binding assays, and cell-based assays to phenotypic assays.
During assay development, optimization of experimental conditions, such as buffer composition, temperature, and reaction time, is performed to ensure robust and reproducible results [6].Controls and reference compounds are included to validate the assay performance and provide a baseline for comparison.Once the compound library and assay are ready, the HTS process begins.It involves steps including plate preparation, compound dispensing, the addition of test samples, incubation and measurement, and data analysis [7].The advantages and limitations of HTS, such as its ability to generate a large number of hits but with potential issues of false positives and false negatives.The time, cost, and resources required for conducting high-throughput screening [8,9].Strategies to improve the efficiency and reliability of HTS, such as the use of advanced robotics, miniaturization, and automated data analysis.

Target-Based Approaches
Target-based approaches involve identifying a specific biological target, such as a protein or enzyme associated with a disease, and designing compounds to modulate its activity [10].While this approach allows for rational drug design, it heavily relies on the detailed knowledge of the target and its associated pathways, which may not always be available or fully understood.Moreover, the experimental determination of the three-dimensional structure of the target protein can be challenging, further complicating the design of targeted drugs [11].Challenges in target identification include the need for comprehensive knowledge of disease pathways and protein structures.

Natural Product Discovery
Natural product discovery involves the exploration of compounds derived from natural sources, such as plants, marine organisms, and microorganisms [12].Natural products have played a crucial role in drug discovery throughout history [13].Many important drugs, including antibiotics, anticancer agents, and cardiovascular medications, have been derived from natural sources [12,13].
Traditional medicine systems worldwide have long utilized natural products for their therapeutic properties.The study of natural products has led to the discovery of bioactive compounds with diverse chemical structures and pharmacological activities [14].The process of natural product discovery involves several steps for isolating, identifying, and characterizing bioactive compounds, including collection from diverse environments, including forests, oceans, and soil, extraction using solvent extraction, maceration, and fermentation, isolation using chromatography, including column chromatography, high-performance liquid chromatography (HPLC), and preparative thin-layer chromatography (TLC), and structure elucidation using nuclear magnetic resonance (NMR), mass spectrometry (MS), and X-ray crystallography.
Natural product discovery faces several challenges, including limited availability, scalability, and modification of natural product structures [15].To overcome challenges in natural product discovery, researchers have adopted various approaches, including bioinformatics tools for genome mining and metagenomics [16].Bioinformatics tools analyze genomic data from organisms to predict and identify potential biosynthetic gene clusters involved in natural product synthesis.This approach facilitates the discovery of novel natural products by targeting specific biosynthetic pathways.In contrast, metagenomics involves the direct analysis of genetic material from environmental samples.It enables the exploration of microbial communities and their potential to produce unique and diverse natural products.

Limitations of Traditional Drug Discovery Methods:
Traditional drug discovery methods, while valuable, face several limitations that impede the efficient and successful development of new drugs [17].Traditional drug discovery processes often suffer from high failure rates and attrition.Many potential drug candidates fail to progress beyond the early stages of development due to issues such as lack of efficacy, poor pharmacokinetics, or unexpected toxicity [18].This attrition leads to significant time and resource wastage.The drug discovery process can be lengthy and costly, from hit-to-lead optimization to clinical development [19].It typically takes several years and requires substantial financial investments to bring a drug candidate from the laboratory to the market.The extensive testing, regulatory requirements, and clinical trials involved contribute to these prolonged timelines and high costs [19].To develop effective drugs, a thorough understanding of the underlying disease biology and the identification of suitable drug targets are crucial.However, in many cases, the mechanisms and pathways associated with diseases are not fully understood, making target identification challenging [20].This lack of comprehensive knowledge can hinder the rational design and development of drugs targeting specific diseases.Traditional drug discovery methods often rely on empirical observations and trial-and-error approaches.This means that researchers explore a large number of compounds or test various modifications without a comprehensive understanding of their mechanisms of action.This trial-and-error process can be time-consuming, resource-intensive, and may not always yield optimal results.The discovery of new chemical scaffolds with unique properties is essential for developing innovative drugs [21].However, traditional methods often rely on existing chemical libraries, leading to a scarcity of novel compounds.This limited chemical diversity can restrict the identification of drugs with novel mechanisms of action or desired pharmacological properties.Furthermore, the risk of developing drugs with limited efficacy or safety concerns remains a challenge.
Addressing these limitations and overcoming the hurdles in traditional drug discovery methods require the integration of computational approaches, advanced technologies, and innovative strategies.The emerging trends in computational approaches for drug discovery offer promising solutions to expedite the process, improve success rates, and optimize the development of safe and effective drugs.
