C4x Discovery's MALT1 inhibitor lead series shows reduced UGT1A1 inhibition at clinically meaningful doses

June 2, 2023
C4x Discovery Holdings plc has announced further progress in its MALT1 inhibitor program for cancer. Building on anti-cancer activity in a preclinical xenograft study, the company completed a preclinical study demonstrating its MALT1 lead compounds were free of UDP glucuronosyltransferase 1 family, polypeptide A1 (UGT1A1) liability shown by competitor chemistries. The program is continuing to identify a shortlist of preclinical candidates for further development, and a partnering program has been initiated.

Identification and development of a PET radiotracer for imaging α-synucleinopathies

June 2, 2023
α-Synucleinopathies constitute a set of neurological disorders including Parkinson’s disease (PD), dementia with Lewy bodies, multiple systems atrophy (MSA), and other rare disorders. The development of positron emission tomography (PET) tracers for imaging α-synuclein aggregates is essential for performing efficient and accurate diagnosis, tracking disease progression and monitoring efficacy of potential therapies.

Macrophage senescence promotes lung cancer progression

June 2, 2023
By Mar de Miguel
With age, senescent cells become detrimental to tissues. Mayo Clinic scientists have observed this phenomenon in the lung alveoli, where senescent macrophages accumulated in aging tissue and in early stages of non-small-cell lung cancer (NSCLC) driven by the Kras oncogene. “We found that the macrophages were present in the earliest stages of the disease. Strategies targeting these cells for elimination or preventing their accumulation would be worthwhile to test in other conditions (assuming we find they occur),” Darren Baker, a Mayo Clinic senescent cell biologist and senior author of the study, told BioWorld.

Intratumor heterogeneity mapped in large study

June 2, 2023
By Helen Albert
A study of more than a thousand tumor samples, led by the Weizmann Institute of Science in Israel, gives valuable insight into the different gene expression patterns seen in different cancers. The new findings could help address challenges associated with targeting many types of tumors, which are hard to treat in large part due to the variable nature of their cells and gene expression patterns, by helping to create better targeted therapeutics.
