Researchers from Zhejiang University of Technology and collaborators presented the discovery and preclinical characterization of YSA-64, a novel RBM39 degrader, in cancer models.

Ubiquitin carboxyl-terminal hydrolase 1 (USP1) is a synthetic lethality target in cancers with high replication stress, such as tumors with BRCA gene mutations or homologous recombination deficiency (HRD). Targeting USP1 has emerged as a promising approach to overcome resistance observed in BRCA/HRD-driven tumors. Aigen Sciences Inc. developed and presented data for AIG-07025, a potent and selective USP1 inhibitor.

Werner syndrome helicase (WRN), belonging to the RecQ helicase family, represents a synthetic lethal vulnerability in MSI-H cancers, providing a strong rationale for therapeutic inhibition. Researchers from Simcere Zaiming Pharmaceutical Co. Ltd. reported the discovery and preclinical characterization of ZMS-4084, a novel WRN inhibitor.
