Features

AI modules purpose-built for RNA drug discovery

ASO design

Drug DiscoveryNew Modality

KumiChem takes each target from sequence to lead: retrieving the full transcript, mapping splice sites and secondary structure to locate accessible binding sites, then generating large batches of chemically optimized ASO candidates at scale.

Every candidate is screened with in silico toxicity and safety evaluation, and cross-referenced against the patent landscape and latest clinical evidence. Multi-parameter filtering and ranking then prioritize the most promising, developable ASOs for experimental validation.

siRNA Design

Drug DiscoveryNew Modality

KumiChem streamlines siRNA development with off-target-aware sequence design, identifying optimal target sites from full mRNA sequences using isoform-aware, structure-guided accessibility analysis.

It performs high-throughput generation of siRNA duplexes with built-in thermodynamic balancing and chemical modification design to enhance potency and stability.

Integrated models score off-target risk, seed homology, and immunogenicity for every candidate, linking each design to relevant patents and scientific literature. Multi-parameter filtering and ranking then prioritize the most selective, developable siRNAs for experimental validation.

Data curation

Data ProcessingDatabase

The MetaAgent achieves effectively unlimited memory by batch-processing large collections of records and synthesizing structured summaries, allowing continuous awareness of all ingested content without context-window constraints.

For example, it can extract mechanism–disease–chemical relationships from the CTD database, mine modification patterns and delivery chemistries from patent corpora, and normalize experimental results from internal screening reports into unified knowledge graphs.

This curated foundation enables downstream agents to reason across heterogeneous sources, linking literature evidence, proprietary datasets, and regulatory knowledge to support more informed new drug design decisions.

Recognition of validity

The premise for conducting data analysis and using its results as guidelines or bases is the recognition of its validity. Validity primarily refers to "statistical significance," with criteria rooted in probability theory's Law of Large Numbers and Central Limit Theorem.

Additionally, data science's dimensionality reduction, forecasting, and classification clustering methods may also utilize highly advanced modern mathematical tools and cutting-edge theories, which contribute to the thriving field of data science and provide a solid scientific foundation for the platform.
