TL;DR: Lanthanide complexes 2, 4, and 6, which were synthesized from 3,5-bis(pyridine-2-ylmethoxy)benzoic acid, were structurally authenticated by single-crystal X-ray diffraction and found to exist as infinite one-dimensional coordination polymers with the general formula {[Ln(L2)(3)(H(2)O)(2)]·xH( 2)O}(n).
Abstract: Two new aromatic carboxylic acids, namely, 3,5-bis(benzyloxy)benzoic acid (HL1) and 3,5-bis(pyridine-2-ylmethoxy)benzoic acid (HL2), have been prepared by replacing the hydroxyl hydrogens of 3,5-dihydroxy benzoic acid with benzyl and pyridyl moieties, respectively. The anions derived from HL1 and HL2 have been used for the support of a series of lanthanide coordination compounds [Eu3+ = 1–2; Tb3+ = 3–4; Gd3+ = 5–6]. The new lanthanide complexes have been characterized on the basis of a variety of spectroscopic techniques in conjunction with an assessment of their photophysical properties. Lanthanide complexes 2, 4, and 6, which were synthesized from 3,5-bis(pyridine-2-ylmethoxy)benzoic acid, were structurally authenticated by single-crystal X-ray diffraction. All three complexes were found to exist as infinite one-dimensional (1-D) coordination polymers with the general formula {[Ln(L2)3(H2O)2]·xH2O}n. Scrutiny of the packing diagrams for 2, 4, and 6 revealed the existence of interesting two-dimensional m...

TL;DR: Because the dissolution rate is inversely proportional to the viscosity, high concentrations of polysorbate 80 increase the visCosity of the micellar solutions to the extent that the dissolve rate is slowed although the total solubility is greatly increased.

TL;DR: In this article, a veterinary antibacterial composition is described which is viscosity stabilized, aqueous, topically adherent and forms a relatively tough, self-supporting film that adheres to the animal until removed by water washing.
Abstract: A veterinary antibacterial composition is described which is viscosity stabilized, aqueous, topically adherent and forms a relatively tough, self-supporting film that adheres to the animal until removed by water washing. The composition is an aqueous solution of: an aliphatic sulfate or sulfonate salt detergent; lactic acid or a food grade salt thereof; a bactericidal food grade organic acid selected from benzoic acid, sorbic acid, citric acid and lower alkanoic acids, and food grade salts thereof; a veterinarily acceptable food grade pectin or gum; and a veterinarily acceptable water soluble emollient selected from short chain aliphatic polyols of up to six carbon atoms; The composition is suitable, for example, as a teat dip and bacterial control approaching 100% is demonstrated by in vitro and in vivo testing.

TL;DR: Comparison of the conformers of these analogues generated by molecular mechanics calculations with the biological activity profiles of these compounds indicates that geometric constraints required for high biological activity are imposed on the bridge joining the two aromatic ring systems by the retinoid receptor.
Abstract: A series of conformationally restricted analogues of (E)-4-[2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)propenyl ] benzoic acid--(E)-4-[1-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)-2 - propenyl]benzoic acid, (E)-4-[3-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)-2-bu ten- 2-yl]benzoic acid, trans-4-[2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl) cyclopropyl]benzoic acid, 4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-anthracenyl)benzoic acid, 6-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)-2- naphthalenecarboxylic acid, 6-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethyl-2-naphthalenyl)-2- naphthalenecarboxylic acid and 6-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)-5-methyl-2- naphthalenecarboxylic acid--were synthesized and screened for retinoid biological activity. Comparison of the conformers of these analogues generated by molecular mechanics calculations with the biological activity profiles of these compounds indicates that geometric constraints required for high biological activity are imposed on the bridge joining the two aromatic ring systems by the retinoid receptor.
