Discovery of RNA Targeting Small Molecules – Our Toolbox for RNA Drug Discovery
Drug Discovery Chemistry Conference 2023 WuXi AppTec has developed technologies to facilitate RNA small molecule screening, an exciting frontier in drug discovery. SHAPE-MaP is applied to determine RNA structure and dynamics and verify small molecule binding. We utilize the “DNA-Zipper” strategy to enable DNA-encoded libraries to identify RNA binders. With other technologies including fragment-based drug …Read More >

How Does It Work? | mRNA Vaccines
If you’ve ever read about mRNA vaccines and wondered, “How Does It Work?” This week’s installment of our video series was made with you in mind. To understand how mRNA vaccines work, let’s take a close look at the immune system. Your immune system can recognize that the structures on bacteria or viruses are different …Read More >
How Does It Work? | Peptide-Oligonucleotide Conjugates
This week’s episode of our “How Does It Work?” series features Peptide-Oligonucleotide Conjugates. Peptide-oligonucleotide conjugates are made up of peptide and oligonucleotide components. These cutting-edge molecules have many applications in biomedicine. The oligonucleotide component can interact with mRNA to alter gene expression within diseased cells but oligonucleotides are easily degraded in the body and have …Read More >
How Does It Work? | Aptamers
Nucleic acids have long been regarded as biological compounds for storing and transferring information. However, their functionalities are far more diverse than this – ranging from gene regulation to enzymatic catalysis. One type of unconventional nucleic acid is the aptamer. Aptamers are short, single stranded nucleic acids that fold into highly specific structures. They bind …Read More >
How Does It Work? | Individualized Oligonucleotide Therapies
In this week’s episode of our “How Does It Work?” video series, we explore Individualized Oligonucleotide Therapies. Around 6 billion letters form the genetic code that makes each person’s biology unique. Genomic sequencing allows us to read this code to find defects that cause disease, enabling us to tailor therapies for individual patients. This was …Read More >
How Does It Work? | Antisense Oligonucleotide Therapy
In this week’s installment of our “How Does It Work?” video series, we’ll explore Antisense Oligonucleotide Therapy. Errors in DNA, known as gene mutations, can originate harmful proteins that cause disease. However, we can target the mRNA involved in the formation of specific disease associated proteins by using drugs called antisense oligonucleotides. They work by …Read More >
