7H-[1,2]Benzothia-zolo[3,2-b]quinazoline 5,5-dioxide.

ABSTRACT: In the title compound, C(14)H(10)N(2)O(2)S, the benzothia-zole and quinazoline ring systems are essentially planar with maximum deviations of 0.0127?(16) and 0.1588?(15)?Å, respectively, and make a dihedral angleof 3.02?(5)°, which shows that the entire mol-ecule is almost planar. The O atoms deviate from the benzothia-zole ring system by 1.2231?(14) and -1.1989?(15)?Å. The crystal packing features non-classical C-H?O hydrogen bonds and is further consolidated by ?-? inter-actions [centroid-centroid distances = 3.7568?(8) and 3.8848?(9)?Å].

In the title compound, C(14)H(10)N(2)O(2)S, the benzothia-zole and quinazoline ring systems are essentially planar with maximum deviations of 0.0127 (16) and 0.1588 (15) Å, respectively, and make a dihedral angleof 3.02 (5)°, which shows that the entire mol-ecule is almost planar. The O atoms deviate from the benzothia-zole ring system by 1.2231 (14) and -1.1989 (15) Å. The crystal packing features non-classical C-H⋯O hydrogen bonds and is further consolidated by π-π inter-actions [centroid-cent ...[more]

4-Methyl-3-phenyl-2,4-dihydro-pyrazolo-[4,3-c][1,2]benzothia-zine 5,5-dioxide.

Project description:In the title mol-ecule, C(16)H(13)N(3)O(2)S, the heterocyclic thia-zine ring adopts a twist chair conformation with the S atom and an adjacent C atom displaced by 0.946 (5) and 0.405 (6) Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The mean planes of the benzene rings make dihedral angles of 16.61 (10) and 15.32 (10)° with the mean plane of the pyrazole ring. The mol-ecular structure is consolidated by intra-molecular C-H⋯N inter-actions and the crystal packing is stabilized by N-H⋯O and C-H⋯N hydrogen bonds. The crystal studied was an inversion twin with the refined ratio of the twin components being 0.53 (11):0.47 (11).

Project description:In the title compound, C(10)H(10)ClN(5), the tetra-zole ring and the phenyl ring make a dihedral angle of 7.7?(2)°.

7-(4-Bromo-phen-yl)-9-phenyl-7H-pyrrolo[3,2-e]tetra-zolo[1,5-c]pyrimidine.

Project description:In the title compound, C(18)H(11)BrN(6), the phenyl ring is almost coplanar [dihedral angle 7.2?(1)°] with the planar (r.m.s. deviation 0.039?Å) tricyclic ring system while the 4-bromo-phenyl ring makes a dihedral angle of 33.98?(6)° with the ring system. Weak inter-molecular C-H?N and C-H?Br hydrogen-bonding inter-actions and ?-? stacking [centroid-centroid distances = 3.7971?(17) and 3.5599?(16)?Å] stabilize the crystal packing. A comparison of the structure to a MOPAC PM3 geometry optimization calculation in vacuo supports these observations.

7-(4-Chloro-phen-yl)-9-phenyl-7H-pyrrolo[3,2-e]tetra-zolo[1,5-c]pyrimidine.

Project description:In the title compound, C(18)H(11)ClN(6), the pyrrole, pyrimidine and tetra-zole rings form a nearly planar fused trihetrocyclic system with an r.m.s. deviation of 0.0387?(13)?Å, to which the 4-chloro-phenyl group and the phenyl group are substituted at the 7 and 9 positions, respectively. The dihedral angles between the pyrrole ring and the 4-chloro-phenyl and phenyl rings are 32.1?(4) and 7.87?(7)°, respectively. In the crystal, weak inter-molecular C-H?N and C-H?Cl hydrogen bonds link the mol-ecules into a layer parallel to the (001) plane. The layers are further connected by ?-? stacking inter-actions [centroid-centroid distances: 3.8413?(8) and 3.5352?(8)?Å]. Intra-molecular C-H?N hydrogen bonds are also present.

Methyl 3-oxo-2,3-dihydro-1,2-benzothia-zole-2-acetate 1,1-dioxide.

Project description:The title mol-ecule, C(10)H(9)NO(5)S, is composed of two essentially planar units with a dihedral angle of 89.16 (6)° between them. In the crystal structure, there are weak inter-molecular C-H⋯O inter-actions resulting in dimeric pairs of mol-ecules about inversion centres and chains of mol-ecules extended along the a and c axes, thus stabilizing the structure. In addition, benzothia-zole rings lying parallel to each other with centroid-centroid distances of 3.679 (2) and 3.999 (2) Å indicate the existence of π-π stacking inter-actions.

Discovery of a Potent Anti-tumor Agent through Regioselective Mono-N-acylation of 7H-Pyrrolo[3,2-f]quinazoline-1,3-diamine.

Project description:7H-Pyrrolo[3,2-f]quinazoline-1,3-diamine (1) is a privileged chemical scaffold with significant biological activities. However, the currently accessible chemical space derived from 1 is rather limited. Here we expanded the chemical space related to 1 by developing efficient methods for regioselective monoacylation at N1 , N3 and N7 , respectively. With this novel methodology, a focused library of mono-N-acylated pyrroloquinazoline-1,3-diamines were prepared and screened for anti-breast cancer activity. The structure-activity relationship (SAR) results showed that N3 -acylated compounds were in general more potent than N1 -acylated compounds while N7 -acylation significantly reduced their solubility. Among the compounds evaluated, 7f possessed 8-fold more potent activity than 1 in MDA-MB-468 cells. More importantly, 7f was not toxic to normal human cells. These results suggest that 7f is a novel compound as a potential anti-breast cancer agent without harming normal cells.

Methyl 4-hydr-oxy-2H-1,2-benzothia-zine-3-carboxyl-ate 1,1-dioxide.

Project description:The asymmetric unit of the title compound, C(10)H(9)NO(5)S, contains two independent mol-ecules. The heterocyclic thia-zine rings in both mol-ecules adopt half-chair conformations, with the S atoms in each mol-ecule displaced by 0.455?(3) and 0.539?(3)?Å and the N atoms displaced in the opposite direction by 0.214?(3) and 0.203?(3)?Å, from the planes defined by the remaining ring atoms. The crystal structure is stabilized by O-H?O, N-H?O and C-H?O hydrogen bonds involving both inter- and intra-molecular inter-actions.

3-Benzoyl-4-hydr-oxy-2-methyl-2H-1,2-benzothia-zine 1,1-dioxide.

Project description:In the title mol-ecule, C(16)H(13)NO(4)S, the heterocyclic thia-zine ring adopts a half-chair conformation with the S and N atoms displaced by 0.410 (3) and 0.299 (3) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The crystal structure is stabilized by inter-molecular hydrogen bonds of the types O-H⋯O and C-H⋯O; the former result in dimers lying about inversion centers and the latter form chains of mol-ecules running along the c axis. In addition, intra-molecular O-H⋯O links are present.
