Progress Update: Reimagining the Science Behind
Mechanism-Based Target Selection & Small Molecule Drug Design

Schematic: Science Reimagined
A new physics-based, holistic view: bridging cellular systems, atomic-level function, and drug action for smarter medicine.
Background: For over five years, our group has championed a holistic, first-principles, physics-based framework for understanding and predicting the complex molecular logic of cell (dys)function and its relationship to drug action—across both atomic and systems scales. This approach challenges the current status quo, directly tackles failure points in drug discovery, and drives new paradigms in both target selection and compound design.

Rethinking Drug Discovery: Dice Loading and Tossing

Loading and tossing the drug discovery dice
Conceptual metaphor—How well do you load the dice before you throw them? (Prediction vs. trial-and-error)

We separate drug discovery into two broad camps:

  1. Loading the Dice: Choosing therapeutic targets, hit, and lead molecules to predict “true-positive” clinical candidates—those actually capable of achieving a therapeutic index in humans.
  2. Tossing the Dice: Preclinical and clinical testing—the real-world confirmation stage, where loaded dice either land as hoped... or not. Most still fail.
Problem Status Quo New Physics-Based Approach
Selecting Targets/Compounds Inadequate models, incomplete/inaccurate criteria, trial-and-error Model non-linear, multi-molecular/ionic dynamics rooted in actual cell/organismal physiology
Predicting Efficacy & Safety Heavily data-driven, disconnected from native biology Direct simulation of binding, permeability, and micro-PK under native conditions
Failure Rate Remains high; little improvement in true-positive clinical prediction Clearer rationale, new tools (e.g., WaterWorks/WATMD, Wat2Mol, CellOS) for head-to-head, first-principles comparison

Why Does the Status Quo Fall Short?

Cellular network complexity
Cellular networks: Everything (really) depends on everything else! Non-linear feedback rules.
Where We’re Trailblazing:
Our in-house platforms—WaterWorks/WATMD (for solvation analysis), Wat2Mol (generative chemistry; 1st place poster, Novartis 2025), and CellOS (cellular network analysis)—address these gaps and show promise for more reliable drug-target/off-target prediction and design.
