Antidesma ghaesembilla is an important medicinal and food plant in many Asian countries. Ten substances could be isolated from the dichloromethane and methanol extract: sitostenone (3), daucosterol (4), chavibetol (5), asperphenamate (6), protocatechuic acid (7), vanillic acid-4-O-beta-D-glucoside (8), 1-O-beta-D-glucopyranosyl- 3-O-methyl-phloroglucinol (9), and aristolic acid II-8-O-beta-D-glucoside (10), and two new aristolic acid derivatives, 10-amino-5,7-dimethoxy-aristolic acid II (= 6-amino-9,11-dimethoxyphenanthro[3,4-d]-1,3-dioxole-5carboxylic acid; 1) and 5,7-dimethoxy-aristolochic acid II (= 9,11-dimethoxy-6-nitrophenantro[3,4-d]-1,3-dioxole-5carboxylic acid; 2). Exposure to humans of some of these compounds is associated with a severe disease today known as aristolochic acid nephropathy. Therefore, the traditional usage of this plant has to be reconsidered carefully.

The far-infrared and Raman spectra of 1,3-benzodioxole vapor have been recorded and analyzed. Forty-one infrared and six Raman bands were assigned to transitions between the various ring-puckering energy levels in the ground and excited ring-napping states. The determination of the energy levels was assisted by analysis of the single vibronic level fluorescence spectra of the jet-cooled molecules. The puckering levels change substantially in the napping excited state, indicating substantial interaction between the two vibrational modes. From the spectroscopic data, a two-dimensional vibrational potential energy surface was determined. This has a barrier to planarity of 164 cm(-1) and energy minima at puckering and napping angles of +/-24 degrees and +/-3 degrees, respectively. This molecule has a lower barrier to planarity than 1,3-dioxole, reflecting the influence of the benzene ring on the anomeric effect. Nevertheless, the anomeric effect is clearly the origin of the nonplanarity of this bicyclic ring system.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 87-72-9 is helpful to your research. Safety of L-Arabinopyranose.

Molecular mutagens and carcinogens are structures which carry chemical and electronic properties that disturb and interact with the genomic machinery. Principally, a rule of thumb for carcinogens is that carcinogens are expected to introduce covalent irreversible bonding to one or several types of DNA bases, causing errors in the reading frame for the polymerases. 8-methoxy-6-nitrophenanthro[3,4-d][1,3]dioxole-5-carboxylic acid, better known as Aristolochic acid (AA1) is a recognized carcinogen which causes urotherial cancer and is found in certain plants. Its structure is particularly interesting given that it is closely related to phenanthrene in its polycyclic arrangement, and has four functional groups, a carboxyl-, a nitro-, a methoxy- and a dioxolane group. In this work, the structure of AA1 has been resolved at the MPWPW91 density functional theory method in combination with Aug-cc-pVDZ basis sets. A geometry analysis shows that in AA1 the carboxyl group’s torsion is caused by steric strain from the nitro group, which elevates the molecular plane of the first phenanthrene ring with 0.1 angstrom. The wavefunction analysis of AA1 shows that the ring deformation enhances a double -bond localization in the first ring, adjacent to the dioxalane group, and results in a decrease of ring aromaticity and induces a potentially frozen resonance. Intermolecular and intramolecular interactions were characterized by atoms in molecules and reduced density gradient analysis. This study brings novel information on the geometry and electronic structure of AA1, which are important for the further knowledge of its transformation in vivo and in situ.

We present a molecular symmetry analysis of electronic states and transition dipole moments for molecules which undergo large amplitude intramolecular torsions. The method is based on the correlation between the point group of the molecule at highly symmetric configurations and the molecular symmetry group. As an example, we determine the global irreducible representations of the electronic states and transition dipole moments for the quinodimethane derivative 2-[4-(cyclopenta-2,4- dien-1-ylidene) cyclohexa-2,5-dien-1-ylidene]-2H-1,3-dioxole for which two torsional degrees of freedom can be activated upon photo-excitation and construct the resulting symmetry adapted transition dipole functions.
