چکیده
In the title mol-ecule, C(12)H(13)NO(5)S, the benzisothia-zole ring system is essentially planar (r.m.s. deviation = 0.0169 Å) as is the -C-C(=O)-O-C- sequence of atoms in the vicinity of the acetate group (r.m.s. deviation = 0.0044 Å). The mean plane of these atoms forms a dihedral angle of 88.41 (7)° with the benzisothia-zole ring system. In the crystal, weak C-H⋯O hydrogen bonds involving methyl-ene and methyne H atoms form R(4) (3)(20) graph-set motifs.

In the mol-ecule of the title compound, C(11)H(10)ClNO(3)S, the benzene and thia-zole rings are oriented at a dihedral angle of 1.25 (3)°. Intra-molecular C-H⋯O and C-H⋯Cl inter-actions result in the formation of two five-membered rings which both adopt envelope conformations.
متن کاملSaccharin Derivatives as Inhibitors of Interferon-Mediated Inflammation
A series of novel, saccharin-based antagonists have been identified for the interferon signaling pathway. Through in vitro high-throughput screening with the Colorado Center for Drug Discovery (C2D2) Pilot Library, we identified hit compound 1, which was the basis for extensive structure-activity relationship studies. Our efforts produced a lead anti-inflammatory compound, tert-butyl N-(furan-2...
