Carcinogenicity of 2-hydroxybenzo(a)pyrene and 6-hydroxybenzo(a)pyrene in newborn mice.

Cancer research, 1979
Benzo(a)pyrene (BP), 2-hydroxybenzo(a)pyrene (2-HOBP), and 6-hydroxybenzo(a)pyrene (6-HOBP) were tested for tumorigenicity by i.p. injection into newborn mice. The mice were treated sequentially with 200, 400, and 800 nmol of compound on the first, eighth and fifteenth day of life, and the animals were killed at 24 weeks of age.

Energetics of Hydroxybenzoic Acids and of the Corresponding Carboxyphenoxyl Radicals. Intramolecular Hydrogen Bonding in 2-Hydroxybenzoic Acid

The Journal of Physical Chemistry A, 2005
The energetics of the phenolic O-H bond in the three hydroxybenzoic acid isomers and of the intramolecular hydrogen O-H- - -O-C bond in 2-hydroxybenzoic acid, 2-OHBA, were investigated by using a combination of experimental and theoretical methods. The standard molar enthalpies of formation of monoclinic 3- and 4-hydroxybenzoic acids, at 298.15 K, were

Synthesis of New Hydroxybenzo[a]carbazoles

Synthesis, 2008
An investigation of the alkylation sites of 4,7-dihydroxybenzo[ A]pyrrolo[3,4- C]carbazole-1,3(2 H,8 H)-dione,as well as the site of reduction in the maleimide upper ring, wascarried out which resulted in the synthesis of diversely substituted4-hydroxybenzo[ A]pyrrolo[3,4- C]carbazoles.

Studies of 7-hydroxybenzo-4-pyrones

Talanta, 1980
Spectral data and rates of hydrolysis in 0.7M potassium hydroxide are reported for a series of nine 7-hydroxybenzo-4-pyrones differing in substitution at positions 2 and 3. The results reveal that 2,3-dimethyl substitution produces a molecule, 7-hydroxy-2,3-dimethylchromone, sufficiently fluorescent and resistant to alkaline hydrolysis to warrant its ...
