10:30 am Morning Break & Speed Networking

11:30 am Identification & Characterization of Small Molecule RNA binders with Affinity Selection Mass Spectrometry (ASMS)

Synopsis

  • PureHoney Tech has optimized a process for high throughput screening of large chemical libraries to identify small molecule binders of RNA targets using ASMS. As many as 100K test compounds can be screened in a little over a day from which hit lists can be generated. The only limitation on target size is solubility allowing for oligos as small as 20 bases and as large as thousands of bases to be screened
  • The binding affinity of hits can be determined by running dose-response experiments to generate binding curves. Alternately the binding affinity of up to 10 test compounds can be rapidly rank ordered by running the test compounds in pools against different concentrations of the RNA target
  • ASMS has been successfully used as a tool in multiple SAR and medicinal chemistry supporting drug development programs

11:50 am Biopharma & Investment Partnerships Panel — Exploring the Future of RNA Investment & Collaborations Space for Small Molecules

Synopsis

The biopharmaceutical sector is considering small molecule medications as a vital component. This community thrives on strategic alliances, which allow for cross-functional sharing of knowledge, skills, and experience across different disciplines to truly advance RNA-targeted small molecule drugs to patients. This session is the ideal opportunity to get face-to-face time with many of the brightest minds working in the RNA small molecule field and establish meaningful business relationships to pursue for the rest of the conference.

  • Exploring the complexities, risk, and decision-making strategies for developing, acquiring, and advancing innovative approaches
  • Where are the gaps using RNA-targeting small molecule approaches that the biotechnology sector can fill?
  • Developing successful expertise in house vs asset acquisition partnering strategies

2:00 pm Expanding the DNA-Encoded Library Toolbox: Identifying Small Molecules that Target RNA

Synopsis

  • RNA targets interact with DEL DNA tags in a sequence dependent manner
  • DNA:RNA interactions induce false negative signals by consuming the majority of sequencing throughput while also promotes false positive features
  • RNA patches can efficiently block the level of DNA:RNA interaction by pre-occupying the binding site on the DNA tags
  • DNA binding motifs and false positives can be predicted by customized algorithms for RNA targets
  • Binders were identified for multiple RNA targets, including FMN Riboswitch and a novel RNA motif predicted from our in-house informatics pipeline
