In a study published in Cancer Cell on May 25, 2023, researchers from the University of Chicago and colleagues reported that the inhibition of YTHDF2, an immune suppressor protein, can be a valuable strategy to improve radiotherapy outcomes by overcoming resistance while enabling extra help from the immune system.
Bayer AG’s copanlisib was approved in China for the treatment of adult patients with relapsed follicular lymphoma who have received at least two prior systemic therapies. It is the first indication approved in the country for copanlisib, which is entering a market with room to grow but marked by some domestic competition.
Providing no details, Mirati Therapeutics Inc. failed to meet its overall survival primary endpoint in the phase III Sapphire trial with sitravatinib. The receptor tyrosine kinase inhibitor was tested in combination with anti-PD-1 checkpoint inhibitor Opdivo (nivolumab, Bristol Myers Squibb Co.) vs. docetaxel in patients with second- or third-line advanced nonsquamous non-small-cell lung cancer. According to Mirati, this patient population consists of about 70,000 people in the U.S. and Europe who have derived prior benefit from a PD-(L)1 inhibitor.
Research at Simcere Zaiming Pharmaceutical Co. Ltd. has led to the development of polycyclic compounds acting as E3 ubiquitin-protein ligase CBL-B inhibitors and thus reported to be useful for the treatment of cancer and autoimmune disease.
China Pharmaceutical University and Jiangsu Chia Tai Tianqing Pharmaceutical Group Co. Ltd. have jointly developed Wee1-like protein kinase (Wee1) inhibitors reported to be useful for the treatment of cancer.
Recent Perha Pharmaceuticals patents describe imidazolone derivatives acting as inhibitors of dual specificity protein kinase CLK1 and/or CLK4 and/or and dual-specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A). As such, they are reported to be useful for the treatment of diabetes, cancer, CDKL5 deficiency disorder, chromosome 22q13 deletion syndrome, Alzheimer’s disease, viral infections, Niemann-Pick disease type C and tauopathies, among others.
Researchers from Guilin Medical University (GLMU) reported the discovery and preclinical evaluation of novel indoleamine 2,3-dioxygenase 1 (IDO-1) inhibitors as potential anticancer agents. Synthesis and optimization of a series of chromone-oxime derivatives containing piperazine sulfonamide moieties led to the identification of compound [I] as the lead IDO-1 inhibitor.
Cancer Research Technology Ltd. and Merck KGaA have jointly patented tricyclic heterocycles acting as transcriptional coactivator YAP1/transcriptional enhancer factor (TEAD) interaction inhibitors.
