Researchers from Southeast University and Huanghuai University have reported the discovery of novel cyclin-dependent kinase 9 (CDK9) inhibitors as potential anticancer agents.
CSPC Pharmaceutical Group Ltd. announced that it has been granted approval by the National Medical Products Administration (NMPA) to conduct clinical trials in China with its oral small-molecule cyclin-dependent kinase 2/4/6 (CDK2/4/6) inhibitor, SYH-2043. In preclinical studies, SYH-2043 demonstrated good antitumor effects in multiple solid tumor types, especially in breast cancer with intrinsic resistance and acquired resistance against CDK4/6 inhibitors.
Researchers from Cytovia Therapeutics Inc. have presented preclinical data for the novel natural killer (NK) cell engager antibody CYT-338, which was designed using the proprietary FLEX-NKTM platform. CYT-338 contains a novel FLEX-linker to redirect NK cells expressing NKp46 activation receptor to kill CD38-expressing tumors, including multiple myeloma (MM). It was observed that the addition of CYT-338 led to dose-dependent enhancement iNK and PBNK cytolysis of the MM tumor spheroids.
The controlled cell death process of apoptosis functions as the first step to any full recovery from injury or disease. In the second step of any recovery process, dead cells are cleared by efferocytosis, a process performed by phagocytotic cells like macrophages. Approximately 200-300 billion apoptotic cells are cleared daily by efferocytosis starting with the recognition of newly extracellular facing phosphatidylserine (PtdSer) by PtdSer-binding proteins present on phagocytotic cells.
In 2022, neuroscience research made significant advances by understanding the role of large-scale neuronal connections in disorders. So did cancer research.
Macrocyclic compounds acting as induced myeloid leukemia cell differentiation protein Mcl-1 inhibitors have been reported in a Zeno Management Inc. patent. They are reported to be potentially useful for the treatment of cancer.
Research at Schroedinger Inc. has led to the development of son of sevenless homolog 1 (SOS1) and SOS1/GTPase KRAS (G12C mutant) interaction inhibitors potentially useful for the treatment of cancer.
Orexin OX2 receptor agonists have been described in a recent Sumitomo Pharma Co. Ltd. patent as potentially useful for the treatment of hypersomnia, narcolepsy and sleep apnea, among others.
Pardes Biosciences Inc. has patented 3C-like proteinase (3CLpro; Mpro; nsp5) inhibitors (particularly HCoV-229E virus and/or SARS-CoV-2 Mpro inhibitors). They are reported to be potentially useful for the treatment of SARS-CoV-2 infections (COVID-19).
