Background

The goal of accessing ADME properties is to understand how a potential drug candidate interacts with the human body, including absorption, distribution, metabolism, and excretion. This knowledge is crucial for evaluating efficacy, safety, and clinical potential, guiding drug development for optimal therapeutic outcomes. Fang et al. 2023 has disclosed DMPK datasets collected over 20 months across six ADME in vitro endpoints, which are human and rat liver microsomal stability, MDR1-MDCK efflux ratio, solubility, and human and rat plasma protein binding. The dataset contains 885 to 3087 measures for the corresponding endpoints.

Benchmarking

The goal of this benchmark is to perform a single task, which is to the best predictive model for human liver microsomal stability.

Description of readout

• Readouts: LOG HLM_CLint (mL/min/kg)
• Bioassay readout: Intrinsic clearance
• Optimization objective: Higher value
• Number of data points: train: 2229, test: 575

Train/test split

In this benchmark set, the same train/test sets in the fang2023 paper were used for the 6 endpoints human and rat liver microsomal stability, MDR1-MDCK efflux ratio, solubility, and human and rat plasma protein binding, respectively.
