Recently, a collaborative paper titled "Development of small molecule inhibitors targeting RNA helicase DHX33 as anti-cancer agents" co-authored by Kaiyue Life Sciences, the University of Macau, Southern University of Science and Technology, and Heya Pharmaceuticals was published online in BMCL, a long-established journal of medicinal chemistry.

The RNA helicase DHX33 has been identified as a key player in promoting cancer development. Genetic deletion of DHX33 significantly blocks tumorigenesis. Importantly, its helicase activity was found to be critical for exerting cellular functions. In this study, a helicase-based high-throughput screening (HTS) technique was used to discover DHX33 inhibitors from the Chembridge chemical library containing 15,000 small molecules. We discovered a lead compound containing a benzimidazole ring that showed some selectivity for DHX33. Further structural optimization led to the design and synthesis of a series of mimetic inhibitors. Considering the potential role of DHX33 in cancer development, we evaluated these compounds based on their cytotoxic activity against U251-MG cancer cells in vitro. Among them, compound IVa (KY386) was identified as a selective inhibitor of DHX33 helicase with strong anticancer activity and moderate metabolic stability. These results support the important role of DHX33 inhibitors in the development of novel anticancer drugs.

The consortium led by InCephalo AG has received the competitive Eurostar grant. The Swiss – Dutch consortium consist of three collaborating partners: InCephalo AG, University of Basel and VitroScan.
In the CLEIO project: The first-in-kind Compartment Locked and Effective ImmunOtherapy against glioblastoma, the consortium will: i) study the effect of InC01 (InCephalo’s primary asset) treatment on established ex- vivo GBM models based on patient tissue, ii) discover new biomarkers for the response and non-response of InC01, and iii) drive clinical Phase II trial design through stratification of patient populations.

«We are excited to receive this grant as will allow us to de-risk our
clinical development at such an early stage» says Dr. Carlo Bertozzi,
CEO and co-founder of InCephalo.

Willemijn Vader, CEO VitroScan:

«It is a great opportunity for VitroScan to collaborate with these partners and integrate our expertise to develop predictive tools for new novel treatment options for glioblastoma patients».

Prof. G. Hutter, Neurosurgeon and Group leader at both the Unversity of Basel and the University Hospital in Basel:

«As a treating physician, I see that novel therapeutic modalities are needed for brain cancer patients. In this collaboration, we are actively working to push InC01, a promising new modality, closer to the patient and on the way learn more about which patients are more likely to react».

ABOUT CIRCLE PHARMA’S CYCLIN A/B INHIBITOR PROGRAM

Circle Pharma has developed an orally bioavailable macrocycle with dual cyclin A and B inhibitory activity that drives synthetic lethality in multiple tumor types. In biochemical and cellular studies, Circle’s cyclin A/B inhibitor has been shown to potently and selectively disrupt the protein-protein interaction between Cyclins A and B and their key substrates, including E2F (a substrate of Cyclin A) and Myt1 (a substrate of Cyclin B). Preclinical studies have demonstrated the ability of these cyclin A/B inhibitors to cause pronounced tumor regression in multiple xenograft models. Circle Pharma plans to file an investigational new drug (IND) application with the U.S. Food and Drug Administration (FDA) for its clinical candidate, CID-078, and initiate clinical development in 2024.
