Independent translational drug discovery

Focused programs. Rigorous evidence. Fast specialist execution.

Radia Research is an independent translational drug-discovery organization operating as a virtual biotech. We retain scientific, program, and IP control while engaging specialist chemistry, biochemistry, microbiology, ADME, structural biology, and later PK/PD partners as programs mature.

Programs

Our public portfolio is intentionally concise. Each program is organized around a bounded development question, a defined empirical gate, and a path to specialist execution.

Flagship antibacterial program

LpxH / Gram-negative antibiotics

Discovery of chemically orthogonal LpxH inhibitor series designed to support Gram-negative entry, experimental validation, and medicinal-chemistry expansion.

  • Initial focus: wild-type E. coli and Klebsiella pneumoniae
  • Paired purified-target biochemistry and whole-cell MIC testing
  • Novel-chemistry strategy shaped for CARB-X 2026 priorities
Current state: calibrated discovery workflow and prospective experimental path.
Antibacterial target-validation program

MurJ

A structurally guided research program centered on the essential bacterial lipid-II flippase MurJ.

  • Prospectively controlled empirical validation
  • Mechanism-focused structural analysis
  • Public descriptions intentionally exclude confidential claim strategy and chemistry
Current state: target-validation research; no public claim of a new chemical inhibitor.
Fibrosis research program

TNIK / MASH & hepatic fibrosis

A mechanistic program focused on advanced MASH and hepatic fibrosis, with emphasis on hepatic stellate-cell biology and collagen production and trafficking.

  • F3 to early compensated F4 transition
  • Mechanistic validation before chemistry claims
  • Confidential candidate structures and internal design space remain private
Current state: mechanistic validation program.

Virtual-biotech model

Radia is built to move quickly without pretending every capability must live inside one organization. The core team defines the scientific thesis, gates, evidence standards, and IP strategy; specialist partners execute the work best suited to them.

What stays with Radia

  • Program architecture and scientific direction
  • Prospective decision rules and evidence gates
  • Computational discovery and prioritization
  • Prior-art and IP-aware program design
  • Program integration and downstream decisions

What can be executed with partners

  • Medicinal and synthetic chemistry
  • Biochemical target assays
  • Antimicrobial susceptibility and resistance studies
  • ADME, permeability, solubility, and selectivity
  • Structural biology and later PK/PD studies

Collaborate

We are interested in research relationships that materially advance a defined program: assay execution, medicinal chemistry, microbiology, structural biology, developability, or translational planning. The best first conversation is concrete—what can be tested, by whom, under what evidence standard, and what decision the result should unlock.

Current priority

For the LpxH program, the immediate experimental objective is a small, diverse, rapidly purchasable compound basket tested in the same cycle for purified LpxH activity and wild-type E. coli/K. pneumoniae MIC. That paired result is designed to distinguish target engagement, entry/efflux limitation, off-target antibacterial activity, and true negatives efficiently.
