Enzymes, the molecular workhorses of cellular processes, have long been recognized as critical players in various physiological pathways [1]. Their fundamental roles in catalyzing biochemical reactions and regulating cellular functions have made them attractive targets for therapeutic intervention [2]. The identification and characterization of enzymes as potential drug targets have paved the way for significant advances in modern medicine, ushering in a new era of precision pharmacology and personalized medicine [3]. This review delves into the current state of knowledge on enzymes as drug targets, exploring the latest advances in enzyme-targeted therapeutics and envisioning future perspectives in this dynamic field. With a focus on "Current Advances and Future Perspectives," we aim to provide a comprehensive overview of the everevolving landscape of enzyme-targeted drug discovery and development [3]. Over the years, extensive research has elucidated the roles of enzymes in diseases ranging from cancer and metabolic disorders to infectious diseases and neurodegenerative conditions [4]. Understanding the molecular mechanisms underlying enzyme function and regulation has opened doors to the design of specific inhibitors and modulators tailored to disrupt aberrant enzymatic activities associated with disease states [5]. The study of enzyme inhibition strategies, both reversible and irreversible, has led to the development of numerous drugs that target enzymes involved in various diseases. Moreover, allosteric regulation, a mechanism through which enzymes can be modulated by ligands at sites distinct from the active site, offers an additional layer of complexity and therapeutic opportunities in drug design [6]. Advancements in technology, such as computational modeling and high-throughput screening, have revolutionized the identification of novel enzyme targets, accelerating the drug discovery process and expanding the arsenal of therapeutic options [7]. Furthermore, the growing emphasis on personalized medicine has paved the way for tailoring drug therapies based on individual patient characteristics, including genetic variations and drug response profiles. In this context, we examine the challenges and opportunities in enzyme-targeted drug development [8]. The pursuit of drug selectivity, minimizing off-target effects, and optimizing drug efficacy are critical considerations in harnessing enzymes as effective therapeutic targets. Understanding enzyme kinetics and their regulation provides insights into the design of drugs with optimal pharmacokinetic and pharmacodynamics properties [9]. As we delve into the current advances, we also look toward the future of enzyme-targeted therapies. The integration of cutting-edge research in enzyme biology, medicinal chemistry, and pharmacology holds promise in addressing unmet medical needs and discovering novel treatment modalities. This review aims to provide a comprehensive and insightful perspective on enzymes as drug targets, offering a glimpse into the ongoing revolution in precision medicine. By exploring the interplay between enzymology and pharmacology, we aspire to contribute to the advancement of therapeutics that harnesses the full potential of enzymes in treating diseases and improving patient outcomes. The quest to unlock new horizons in drug development continues, and enzymes stand at the forefront of this transformative journey [10].

Through a combination of computational modeling and high-throughput screening, several novel enzymes were identified as potential drug targets. These enzymes play critical roles in disease-related pathways and represent promising avenues for therapeutic intervention. In vitro enzyme inhibition assays revealed several lead compounds that demonstrated potent inhibitory activity against target enzymes. IC50 values were determined for the lead compounds, indicating their ability to effectively inhibit enzyme activity. Allosteric regulation was observed for certain enzymes, offering alternative sites for therapeutic intervention beyond the active site. Allosteric modulators showed the potential to fine-tune enzyme activity, providing opportunities for selective drug design. Cell-based assays demonstrated that selected enzyme inhibitors effectively suppressed disease-related cellular pathways. Treatment with enzyme inhibitors resulted in reduced cell proliferation and altered expression of disease markers. In animal models, administration of enzyme-targeted therapeutics resulted in significant reductions in disease progression and improved overall survival (Tab.1.). Pharmacokinetic studies indicated favorable drug properties, including reasonable half-lives and tissue distribution. Analysis of patient samples revealed genetic variations associated with drug response to enzymetargeted therapies. Pharmacogenomics data provided insights into individual variability in drug metabolism and efficacy. Synergistic effects were observed when enzyme inhibitors were combined with conventional therapeutics or other targeted agents (Fig.1.). Combinatorial approaches demonstrated enhanced efficacy and reduced potential for drug resistance. Detailed safety assessments indicated a favorable toxicity profile for selected enzymetargeted drugs. Off-target effects were minimal, supporting the selectivity of the enzyme inhibitors. Some enzymes presented challenges in drug development due to their complex regulatory mechanisms and substrate specificities. Overcoming these challenges may require innovative drug design strategies and further mechanistic studies.
