Abstract
Synthetic nucleoside or nucleotide analogues played a key role to the development of antiviral agents in past decades. However, low membrane permeability and insufficient cellular phosphorylation impaired the biological activity of polar nucleoside drugs because they have to penetrate the cell membrane and be phosphorylated to active metabolite stepwise by intracellular enzymes. To overcome these limitations, diverse lipophilic prodrug modifications based on nucleoside mono-, di-, and triphosphate were designed and put into practice to efficiently deliver nucleoside into the target site, and bypass the rate-limited phosphorylation step. As the most successful prodrug strategy, ProTide technology has led to the discovery of three FDA-approved antiviral agents, including sofosbuvir, tenofovir alafenadmide, and remdesivir, which has been authorized for emergency use in patients of COVID-19 in the US. In recent years, nucleoside di- and triphosphate prodrugs have also made the significant progress. This review will focus on the summary of design approach and metabolic activation path of different nucleotide prodrug strategies. The potential application of nucleotide prodrugs for the treatment of COVID-19 was also described due to the pandemic of SARS-CoV-2.

AlphaFold in Medicinal Chemistry: Opportunities and Challenges
AlphaFold, a groundbreaking AI tool for protein structure prediction, is revolutionizing drug discovery. Its near-atomic accuracy unlocks new avenues for designing targeted drugs and performing efficient virtual screening. However, AlphaFold's static predictions lack the dynamic nature of proteins, crucial for understanding drug action. This is especially true for multi-domain proteins, ...read more
Artificial intelligence for Natural Products Discovery and Development
Our approach involves using computational methods to predict the potential therapeutic benefits of natural products by considering factors such as drug structure, targets, and interactions. We also employ multitarget analysis to understand the role of drug targets in disease pathways. We advocate for the use of artificial intelligence in predicting ...read more
Chemistry Based on Natural Products for Therapeutic Purposes
