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.
Researchers have developed a new highly effective therapeutic for pain relief by altering the chemical properties of an antinausea drug, netupitant. The modified drug is able to enter the intracellular membrane-bound endosome and target the GPCRs therein, rather than at the cell surface, that leads to optimal pain relief. The study, published in the Proceedings of the National Academy of Sciences (PNAS) on May 22,2023, was led by Nigel Bunnett, Professor and Chair of Molecular Pathobiology at NYU College of Dentistry, and illustrates how GPCR-mediated pain signaling occurs inside the endosomes rather than at the surface, highlighting the need for drugs that can reach receptors within the cells itself.
The researchers who enabled patients with spinal cord injuries to walk independently after implanting programmable electrodes below their lesions have now taken things one step further, restoring direct communication from the brain to the spinal cord, enabling the brain rather than an external computer to direct leg movements.
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.
Proteolysis targeting chimera (PROTAC) compounds comprising an E3 ubiquitin ligase binding moiety covalently linked to non-receptor tyrosine-protein kinase TYK2-targeting moiety have been reported in a Kymera Therapeutics Inc. patent as potentially useful for the treatment of neurological, inflammatory and endocrine disorders, autoimmune diseases, transplant rejection, graft-vs.-host disease and 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.
