China’s National Medical Products Administration (NMPA) has accepted Ascentage Pharma Group Corp. Ltd.’s NDA for its in-house-developed Bcl-2 selective inhibitor, lisaftoclax (APG-2575), which could be the first domestically approved Bcl-2 inhibitor in China and the second global approval.
Resistance to radiotherapy is a crucial factor in the outcome of colorectal cancer (CRC). The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway plays a key role in cell growth, differentiation, proliferation and immune function.
Bladder cancer is characterized by a high recurrence rate, with limited therapeutic options available. There is a need to discover new therapeutic targets and approaches to overcome this.
Researchers from the University of Minnesota and collaborators have synthesized and evaluated a novel series of antiproliferative benzofuran derivatives that led to the identification of [I] as the most potent candidate.
Integrated Biosciences Inc., an early-stage startup that is combining synthetic biology and machine learning in the hunt for drugs that tackle cell senescence, has demonstrated its capabilities in a newly published study in Nature Aging on May 4, 2023, which employed artificial intelligence to identify three novel compounds that are highly selective for Bcl-2 and that exhibit favorable medicinal chemistry profiles.

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.
Surviving apoptosis after administration of a drug triggered a previously unknown evolutionary process that gave tumor cells greater resistance to subsequent therapies. A cancer cell that does not die gets stronger. Cancer reappears with those cells that escape death thanks to a mechanism that, at the same time, offers a potential therapeutic target. According to a study led by St. Jude Children's Research Hospital in collaboration with the University of Glasgow and University of Oxford, the alternative to the cell death program is a stress response pathway that generates a persister cell phenotype not described before.
By combining an activator of the pro-apoptotic protein Bax with an inhibitor of the anti-apoptotic protein BCL-XL, researchers at Albert Einstein College of Medicine have been able to overcome resistance to apoptosis in both a wide range of cell lines and animal studies. The team reported its findings in the March 7, 2022, issue of Nature Communications.
