Abstract

Insights

Recent patents reveal diverse lysine-specific demethylase 1 (LSD1) inhibitors, including Tranylcypromine derivatives and natural products, showing promising anticancer activity. These findings offer valuable insights for developing novel LSD1 modulators with improved efficacy and safety.

Area of Science:

  • Oncology
  • Medicinal Chemistry
  • Drug Discovery

Background:

  • Lysine-specific demethylase 1 (LSD1), a FAD-dependent enzyme, is overexpressed in various cancers.
  • LSD1 regulates gene transcription linked to cancer development, making it a therapeutic target.
  • Targeting LSD1 with inhibitors presents a novel strategy for anticancer drug development.

Purpose of the Study:

  • To review patents on LSD1 inhibitors published within the last five years.
  • To provide a reference for researchers developing potent and safe LSD1 modulators.
  • To highlight structural diversity and therapeutic potential of emerging LSD1 inhibitors.

Main Methods:

  • Systematic patent search using Espacenet®, Google Patents, and CNKI databases.
  • Inclusion of patents disclosing LSD1 inhibitors since 2016.
  • Analysis of compound structures and reported biological activities.

Main Results:

  • Dozens of patents related to LSD1 inhibitors were identified from the past five years.
  • Compound structures encompass Tranylcypromine derivatives, imidazole, pyrimidine derivatives, natural products, and peptides.
  • Several compounds have advanced to clinical trials, demonstrating therapeutic progression.

Conclusions:

  • Compounds in reviewed patents exhibit significant in vitro and in vivo antitumor activity.
  • The structural diversity of LSD1 inhibitors is evident, with natural products showing promise.
  • Patent landscape indicates active research and development in LSD1-targeted cancer therapies.
