Anti-anxiety, Anti-depressant and Anti- Cataleptic Activity of 4-hydroxy-3-[2-(3-nitrophenyl)-2, 3-dihydro-1, 5- Benzothiazepin-4-yl]-2h-chromen-2-one
The Present study was aimed to evaluate the therapeutic effectiveness of 1, 5-benzothiazapine derivative in central nervous diseases. 1,5Benzothiazipines are the seven–membered heterocyclic ring systems which are reported for their behavioral activities. In the current research, we have investigated the effect of 1,5-benzothiazine derivative for its anti-anxiety, antidepressant and anti-catalep...

In the title mol-ecule, C(16)H(19)BrO(3), all non-H atoms apart from the Br atom are approximately coplanar, with a maximum deviation of 0.242 (4) Å. The C-C-C-Br torsion angle is 66.5 (4)°.
متن کامل7-Diethylamino-3-{(E)-4-[(E)-2-(pyridin-4-yl)ethenyl]styryl}-2H-chromen-2-one
In the title coumarin derivative, C28H26N2O2, the coumarin unit is approximately planar, with a maximum deviation of 0.048 (3) Å. The central benzene ring is oriented at dihedral angles of 30.15 (14) and 10.51 (11)°, respectively, to the pyridine ring and coumarin ring system. In the crystal, weak C-H⋯O and C-H⋯N hydrogen bonds and weak C-H⋯π inter-actions link the mol-ecules into a three-dimen...

In the title mol-ecule, C(12)H(10)Br(3)NO(2), the 2H-chromen ring is essentially planar (r.m.s. deviation = 0.022 Å) with the ethyl-amino group oriented at 13.9 (5)° with respect to the ring. The mol-ecular structure is stabilized by intra-molecular N-H⋯Br and C-H⋯Br interactions.
متن کامل3,6-Dibromo-7-ethylamino-4-methyl-2H-chromen-2-one
In title compound, C(12)H(11)Br(2)NO(2), the coumarin ring system is almost planar, the two rings being inclined to one another by 1.40 (15)°. There are two short intra-molecular inter-actions (N-H⋯Br and C-H⋯Br) involving the Br atoms. In the crystal, mol-ecules stack along the a-axis direction via π-π inter-actions; the centroid-centroid distances vary from 3.6484 (19) to 3.7942 (19) Å.
