Crystal structure of methyl 5-acetamido-2-t-butyl-2-methyl-1,3-benzodioxole-4-carboxylate.
1,3-benzodioxle-4-carboxylic acid] was designed as a novel class of chiral fluorometric agents.1 The chiral agent and the analogues have been conveniently applied to enantiomer analyses of various bio-molecules using HPLC and circular dichroism.2 We recently extended the molecular design of (S)TBMB carboxylic acid to chiral nitrobenzoic acids possessing the asymmetric 1,3-benzodioxole.3 The chi...
متن کامل6-Hydroxy-2H-1,3-benzodioxole-5-carbaldehyde
The title compound, C(8)H(6)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. The benzodioxole ring system is almost planar in each mol-ecule, with maximum deviations of 0.008 (1) and 0.007 (1) Å. The mol-ecular structure is characterized by strong electrostatic intra-molecular O⋯O contacts [2.649 (3) Å] and intra-molecular O-H⋯O hydrogen-bonding inter-actions. Inter-mo...
متن کامل5-(1H-Inden-2-yl)-1,3-benzodioxole
In the title compound, C(16)H(12)O(2), the non-H atoms are coplanar with a mean r.m.s. deviation of 0.0260 (2) Å. The deviations of the bond angles from normal values at the indenyl junction C atom and the indenyl bridgehead C atom nearest the junction are imposed by the five-membered ring geometry. Due to conjugation, the single bond linking the two ring systems [1.455 (3) Å] is significantly ...
متن کاملBulky DNA adducts and risk of cancer: a meta-analysis.
We present a meta-analysis to test the hypothesis that the presence of a high level of bulky DNA adducts in tissues is associated with an increased risk of cancer in humans. Seven articles were selected that matched the selection criteria, for a total of 691 cancer patients and 632 control subjects. In five studies the cases had lung cancer, in one oral cancer, and in one bladder cancer. Six st...
متن کاملFormation and Repair of Tobacco Carcinogen-Derived Bulky DNA Adducts
DNA adducts play a central role in chemical carcinogenesis. The analysis of formation and repair of smoking-related DNA adducts remains particularly challenging as both smokers and nonsmokers exposed to smoke are repetitively under attack from complex mixtures of carcinogens such as polycyclic aromatic hydrocarbons and N-nitrosamines. The bulky DNA adducts, which usually have complex structure,...
