Synthesis and anticonvulsant activity of some new 2-substituted 3-aryl-4(3H)-quinazolinones.
A series of 4(3H)-quinazolinones structurally related to 2-methyl-3-o-tolyl-4(3H)-quinazolinone (methaqualone, 3) were synthesized and evaluated for anticonvulsant activity. Preliminary screening of these compounds revealed that 2-[2-oxo-2-(4-pyridyl)ethyl]-3-aryl-4(3H)-quinazolinones 6l and 8i, 8k, and 8p-r having a single ortho substituent on the 3-aryl group had the most promising anticonvul...
متن کاملNovel 3-(p-substituted phenyl)-6-bromo-4(3H)-quinazolinone derivatives of promising antiinflammatory and analgesic properties.
A new series of the title compounds incorporated into diverse N and O heterocyclic moieties of pharmacoavailability as anti-inflammatory or analgesic agents, were synthesized starting with 6-bromo-2-phenyl-4H-3,1-benzoxazin-4-one (I) by its fusion with p-aminoacetophenone to give the intermediate compound, 6-bromo-2-phenyl-3-(4-acetylphenyl)-4(3H)quinazolinone (II). The one pot reaction of II w...
متن کامل6-Bromo-1-methyl-4-[2-(4-methylbenzylidene)hydrazinylidene]-3H-2λ6,1-benzothiazine-2,2-dione
In the title compound, C(17)H(16)BrN(3)O(2)S, the two fused rings are twisted by a dihedral angle of 6.61 (15)°. The thia-zine ring adopts a sofa conformation. The toluene ring is oriented at dihedral angles of 15.5 (2) and 20.6 (2)° with respect to the bromo-benzene and thia-zine rings, respectively. The benzyl-idene system is approximately planar [r.m.s. deviation = 0.0388 Å]. In the cyrstal,...
متن کامل2-(5-Bromo-2-hydroxyphenyl)-1,2-dihydroquinazolin-4(3H)-one
The asymmetric unit of the title compound, C(14)H(11)BrN(2)O(2), contains two independent mol-ecules connected into a dimer by inter-molecular N-H⋯O hydrogen bonds involving the amine and carbonyl groups. The dimers are further connected by O-H⋯O hydrogen bonds, forming chains running parallel to the a axis, which are stabilized through π-π stacking inter-actions, with a centroid-centroid dista...
متن کامل3-Benzyl-6-bromo-2-(2-furyl)-3H-imidazo[4,5-b]pyridine
In the title mol-ecule, C(17)H(12)BrN(3)O, the imidazopyridine ring system is almost coplanar with the furan ring [dihedral angle = 2.0 (3)°]. The benzyl phenyl ring is oriented at dihedral angles of 85.2 (2) and 85.5 (1)°, respectively, with respect to the furan ring and the imidazopyridine ring system. In the crystal, mol-ecules are linked into chains propagating along the b axis by C-H⋯N hyd...
