N-Acetyl-4-(benzenesulfonamido)benzenesulfonamide
In the mol-ecule of the title compound, C(14)H(14)N(2)O(5)S(2), the dihedral angle between the aromatic rings is 77.75 (9)°. The acetamide group is planar [maximum deviation = 0.002 (3) Å] and oriented at dihedral angles of 13.49 (21) and 73.94 (10)° with respect to the aromatic rings. An intra-molecular C-H⋯O inter-action results in the formation of a six-membered ring. In the crystal structur...
متن کاملN,N′-Diacetyl-N′-[(4-nitrophenoxy)acetyl]acetohydrazide
The asymmetric unit of the title compound, C(14)H(15)N(3)O(7), contains two independent mol-ecules which are linked into a pseudocentrosymmetric dimer by a π-π inter-action, as shown by the short distance of 3.722 (5) Å between the centroids of the benzene rings. An extensive network of weak inter-molecular C-H⋯O hydrogen bonds helps to stabilize the crystal packing.
متن کاملInhibition of N-acetylneuraminate lyase by N-acetyl-4-oxo-D-neuraminic acid.
We show that the 4-oxo analogue of N-acetyl-D-neuraminic acid strongly inhibits N-acetylneuraminate lyase (NeuAc aldolase, EC 4.1.3.3) from Clostridum perfringens (Ki = 0.025 mM) and Escherichia coli (Ki = 0.15 mM). In each case the inhibition was competitive. N-Acetyl-D-neuraminic acid; N-Acetylneuraminate lyase; N-Acetyl-D-neuraminic acid analog; 5-Acetamido-3,5-dideoxy-beta-D-manno-non-2,4-d...
متن کاملN-Acetyl-N-[2,4-dicyano-1-(4-methoxyphenyl)-9,10-dihydrophenanthren-3-yl]acetamide
In the title compound, C(27)H(21)N(3)O(3), the cyclo-hexa-1,3-diene ring has a screw-boat conformation, and the fused ring system is folded, the dihedral angle between the outer benzene rings being 27.61 (6)°. The N-acetyl-acetamide residue (r.m.s. deviation = 0.0935 Å) has an anti conformation and is essentially perpendicular to the benzene ring to which it is connected [dihedral angle = 89.14...
متن کاملN-[4-Acetyl-5-(4-fluorophenyl)-4,5-dihydro-1,3,4-thiadiazol-2-yl]acetamide
The title mol-ecule, C12H12FN3O2S, shows a short intra-molecular S⋯O contact of 2.682 (18) Å. The dihedral angle between the thia-diazole ring and the benzene ring is 86.82 (11)°. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds generate an R 2 (1)(6) graph-set motif between adjacent mol-ecules. Pairs of futher C-H⋯O hydrogen bonds form inversion dimers with R 2 (2)(8) ring motifs. These combine ...
