β-Lactamases are a family of enzymes that hydrolyze the β-lactam ring and inactivate β-lactam antibacterial agents, constituting a major molecular basis for acquired bacterial resistance. β-Lactam antibiotics primarily target penicillin-binding proteins (PBPs) and disrupt peptidoglycan ...
Apoptosis is a regulated process of programmed cell death in which cells initiate internal signaling pathways that lead to their own elimination. This mechanism is essential for normal development and tissue homeostasis, but it can also be triggered by external stressors such as hypoxia, ionic ...
A paper published August 24 at Org. Process Res. Dev by Professor Sean M. Kell et al. describes a robust and efficient continuous flow process technique for the synthesis of quinazoline organozinc reagents for KRAS G12C inhibitor divarasib.
The targets of action of drugs involve receptors, enzymes, ion channels, transporters, immune system, genes and many others. This paper describes four drugs involving enzyme targets of action and their synthetic routes.
Small molecule inhibitors are one of the most accessible and versatile tools for understanding protein function and its role in normal physiology and disease pathology. To be valuable in questioning biological processes or validating new targets, these tools must meet the criteria necessary to ...
Neurons are central nervous system (CNS) cells that receive and transmit electrochemical signals through a process called neurotransmission. The anatomy of neurons is designed to receive and send messages from neighboring cells. The axonal burst sends signals, and the dendrites receive messages ...
The formation of mutations and the development of cancer both involve damage to a cell's DNA. DNA in human cells is damaged thousands to millions of times a day by both external (exogenous) and internal metabolism (endogenous). Changes in a cell's genome can lead to errors in the transcription ...
Alzheimer's disease is one of the most common neurodegenerative diseases in the world. The clinical manifestations are extracellular amyloid plaques and intracellular neurofibrillary tangles that lead to neuronal dysfunction and cell death. At the heart of the disease is differential processing ...
