T0070907 (CAS 313516-66-4)

T0070907 is a widely utilized organochlorine compound in scientific research, offering potential applications in various fields such as pharmacodynamics, and more. This cell-permeable chloro-nitro-benzamido compound acts as a potent, specific, irreversible, and high-affinity antagonist of PPARγ, displaying a Ki value of 1 nM. It exhibits remarkable selectivity for PPARγ over PPARα and PPARδ (Ki values of 0.85 μM and 1.8 μM, respectively). T0070907 effectively impedes hormone- and agonist-induced adipogenesis in 3T3-L1 cells, blocking interactions between PPARγ and coactivator-derived peptides while facilitating recruitment of corepressor-derived peptides. Through covalent binding to Cys313 in the ligand-binding domain, it modulates the interaction of PPARγ2 with cofactor proteins. The inhibitory potential of T0070907 has been investigated against various bacteria, including E. coli and S. aureus, as well as several fungi, such as Candida albicans and Aspergillus flavus. Moreover, studies have explored its capacity to impede tumor cell growth in mice, alongside anti-inflammatory and antioxidant properties. Although the precise mechanism of action of T0070907 remains under investigation, it is postulated that this compound exerts its biological activity by binding to specific proteins on the cell membrane, thereby impeding cellular growth and proliferation.
