چکیده
The asymmetric unit of the title co-crystalline 1:2 adduct, C(12)H(12)N(2)O(2)·2C(6)H(3)N(3)O(6), contains two independent mol-ecules of bis-(4-amino-phen-yl) sulfone (the drug Dapsone) and four mol-ecules of 1,3,5-trinitro-benzene and is extended into a two-dimensional hydrogen-bonded network structure through amino N-H⋯O hydrogen-bonding associations with nitro O-atom acceptors. In the two independent Dapsone mol-ecules, the inter-ring dihedral anges are 69.6 (3) and 63.63 (9)°. Aromatic π-π inter-actions are also found between one of the Dapsone aromatic rings and a trinitro-benzene ring [minimum ring centroid separation = 3.596 (3) Å]. A 4-amino-phenyl ring moiety of one of the Dapsone mol-ecules and two nitro groups of a trinitro-benzene are disordered in a 50:50 ratio.

In the title compound, C(12)H(12)N(2)O(2)S, the aromatic rings are oriented at a dihedral angle of 79.48 (4)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two five-membered rings with envelope conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules. π-π Contacts between the benzene rings, [centroid-centroid distance = 4.211 (3) Å] ma...
متن کاملDiscovery and characterization of triaminotriazine aniline amides as highly selective p38 kinase inhibitors.
The p38 mitogen-activated protein (MAP) kinases are a family of serine/threonine protein kinases that play important roles in cellular responses to inflammation and external stress. Inhibitors of the p38 MAP kinase have shown promise for potential treatment of inflammatory disorders such as rheumatoid arthritis, acute coronary syndrome, psoriasis, and Crohn's disease. We identified a novel clas...
