Introduction to [18F]F-D3FSP (18F-P16-129, 18F-D3-AV45)

A next-generation β-amyloid PET imaging agent

  • with improved pharmacokinetics, higher imaging contrast, and better diagnostic performance than its predecessors

1. Chemical Structure and Mechanism:

[18F]F-D3FSP is structurally derived from [18F]Florbetapir, with three deuterium atoms strategically placed to enhance its pharmacokinetics and metabolic stability.

2. Clinical and Research Significance

    With its superior metabolic stability and imaging properties, [18F]F-D3FSP is expected to:

      • Enhance early and accurate AD diagnosis, improving patient stratification.
      • Support longitudinal studies of amyloid progression and treatment response.
      • Facilitate clinical trials of emerging AD therapies, optimizing patient selection.
