چکیده
The title compound, C(13)H(13)NO(2)S, was prepared by a thermocyclization reaction from 3-methyl-6-(2-methyl-but-3-yn-2-yl-oxy)benzo[d]thia-zol-2(3H)-one. In the crystal structure, the methyl-thia-zole unit is planar, while the pyran ring assumes a screw-boat conformation. Intra-molecular C-H⋯O hydrogen bonding helps to stabilize the molecular structure.

The title compound, C(17)H(15)Br(2)NO(6)S(2)·C(2)H(5)OH, is the esterification reaction product of 2-(8,10-dibromo-2,6-dioxo-3,5,5a,11b-tetra-hydro-2H,6H-chromeno[4',3':4,5]thio-pyrano[2,3-d]thia-zol-5a-yl)acetic acid. Cleavage of the lactone ring and formation of eth-oxy-carbonyl and hy-droxy groups from its structural elements were observed. On the other hand, the carb-oxy-methyl group was no...

In the title compound, C39H38N4O8, the quinoxaline and indene subunits are essentially planar, with maximum deviations of 0.071 (2) and 0.009 (2) Å, respectively. The indeno-quinoxaline system forms a dihedral angle of 72.81 (3)° with the chromenopyrrolizine system. The two dioxolane rings, as well as the pyran ring of the chromeno group and the terminal pyrrolizine, each adopt an envelope conf...
متن کاملEffect of substituents of alloxazine derivatives on the selectivity and affinity for adenine in AP-site-containing DNA duplexes.
Using the DNA duplex containing an AP site (5'-TCC AGX GCA AC-3'/3'-AGG TCN CGT TG-5', X = AP site, N = A, T, C, or G), we have found that 2-amino-4-hydroxypteridine (pterin) selectively binds to guanine (G), and that the enhanced binding affinity for G is obtained by its methylated derivative 2-amino-6,7-dimethyl-4-hydroxypteridine (diMe pteridine). Similarly, among the cytosine (C)-selective ...

Benzamides and nicotinamides represent classes of drugs that have experienced an unusually broad spectrum of clinical development in a number of therapeutic areas [1]. One of their principal targets is the nuclear DNAbinding protein poly(ADP-ribose) polymerase-1 (PARP1), which is activated by nicks in DNA during inflammation, ischemia, neurodegeneration, and cancer therapy. When over-activated,...
