TG 100801 Hydrochloride is primarily used in research and development within the pharmaceutical industry. It serves as a potent and selective inhibitor of PI3Kδ and PI3Kγ isoforms, which are involved in various cellular processes such as immune response, inflammation, and cancer progression. This compound is particularly valuable in preclinical studies aimed at understanding the role of these kinases in diseases like chronic inflammation, autoimmune disorders, and certain types of cancer. By inhibiting these pathways, it helps researchers explore potential therapeutic strategies and evaluate the efficacy of targeted treatments. Additionally, TG 100801 Hydrochloride is utilized in the development of novel drugs that aim to modulate immune responses and reduce inflammation, offering potential benefits for patients with conditions such as rheumatoid arthritis, asthma, and other inflammatory diseases. Its application extends to high-throughput screening assays to identify new drug candidates and optimize existing therapies.
