CAL-101 is a compound utilized in various research disciplines, particularly in the study of signal transduction pathways. It acts as an inhibitor of the enzyme phosphoinositide 3-kinase p110δ (PI3Kδ), which is a critical component of the PI3K/Akt signaling pathway. Research involving CAL-101 primarily focuses on understanding the role of PI3Kδ in the modulation of cellular functions, such as cell growth, proliferation, and survival. Studies also explore how CAL-101 impacts immune cell function and signal transduction, providing insights into the regulation of immune responses. Additionally, the compound is of interest in cellular and molecular biology research to investigate the consequences of PI3Kδ inhibition on various cell types and the potential compensatory mechanisms that may be activated in response to this inhibition.
