The gene for the prototype acute phase reactant, Creactive protein, has been isolated from two X phage libraries containing inserted human DNA fragments using synthetic oligonucleotide probes. Nucleotide sequence analysis indicates that after coding for a signal peptide of 18 amino acids and the first two amino acids of the mature protein, there is an intron of 278 base pairs followed by the nu...
متن کامل2-(4-Chlorophenyl)-6-methoxychroman-4-one
In the title mol-ecule, C(16)H(13)Cl O(3), the two aromatic rings form a dihedral angle of 65.3 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed into columns propagating in [100] by weak C-H⋯π inter-actions.
متن کامل6-(4-Aminophenyl)-2-methoxy-4-phenylnicotinonitrile
In the structure of the title nicotino-nitrile derivative, C19H15N3O, the pyridine ring makes dihedral angles of 11.50 (7) and 43.36 (8)° with the 4-amino-phenyl and phenyl rings, respectively, and the dihedral angle between the phenyl rings is 36.28°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into wave-like sheets parallel to (10-2). These sheets are stacked by π-π inter-ac...
متن کامل6-Chloro-2-(4-methoxyphenyl)-4-phenylquinoline
In the title compound, C22H16ClNO, the quinoline ring system makes dihedral angles of 56.30 (6) and 7.93 (6)°, respectively, with the adjacent phenyl and benzene rings. The dihedral angle between these phenyl and benzene rings is 56.97 (8)°. In the crystal, weak C-H⋯π and π-π [centroid-centroid distances of 3.7699 (9) and 3.8390 (9) Å] inter-actions link the mol-ecules into a layer parallel to ...
متن کامل6-(4-Aminophenyl)-4-(4-ethoxyphenyl)-2-methoxynicotinonitrile
In the title mol-ecule, C(21)H(19)N(3)O(2), the central pyridine ring makes dihedral angles of 14.46 (9) and 34.67 (8)° with the 4-amino- and 4-eth-oxy-substituted benzene rings, respectively. The eth-oxy group is essentially coplanar with the attached benzene ring [C-O-C-C torsion angle = 178.70 (16)°] as is the meth-oxy group with the pyridine ring [C-O-C-N torsion angle = -3.0 (3)°]. In the ...
