RNA-targeted drug design represents a transformative approach in modern therapeutics, offering unprecedented opportunities to treat diseases at the genetic level. With advancements in computational biology, RNA drug discovery has evolved significantly, leveraging CD ComputaBio specializes in integrating cutting-edge computational methods to facilitate RNA drug discovery, optimizing lead compounds, and enhancing therapeutic efficacy.
Introduction to RNA Drug Design
RNA is no longer seen merely as an intermediate in the central dogma of molecular biology, but as a dynamic and versatile molecule with diverse functions. It participates in gene expression regulation, protein synthesis, and cellular signaling. RNA drug design aims to develop small molecules, nucleic acid-based agents, or peptides that can specifically interact with RNA structures or modulate RNA-associated biological processes. These drugs can disrupt abnormal RNA-related pathways in diseases, correct malfunctioning RNA-mediated gene expression, or inhibit the replication of RNA-based pathogens.

Classification of RNA Drugs
- Small Interfering RNA (siRNA): Silences target genes through RNA interference (RNAi).
- Antisense Oligonucleotides (ASOs): Binds to complementary RNA to modulate splicing or degradation.
- mRNA Therapeutics: Delivers mRNA to encode therapeutic proteins.
- RNA Aptamers: Binds specific proteins with high affinity, functioning similarly to antibodies.
Designing RNA drugs presents unique challenges, including stability, delivery, and off-target effects. Computational approaches play a pivotal role in overcoming these hurdles by enabling rational drug design, structural prediction, and optimization.
