The title compound, C(15)H(20)O(3), a sesquiterpene lactone, was isolated from the aerial parts of Carpesium minus Hemsl. (Compositae). The mol-ecule is composed of three rings, with the two cyclo-hexane rings in chair conformations and the cyclo-pentane ring adopting a twist conformation. The A/B ring junction is trans-fused. The absolute configuration shown has been arbitrarily assigned. In t...
متن کاملExpression of Human Kallikreins 4, 8, 10, 11 and 13 in Pleomorphic Adenomas and Mucoepidermoid Carcinomas
Background: In cancers of prostate, breast, oropharynx, lung, hypopharynx and skin, human tissue kallikreins has been demonstrated as a main role in these problems. There are many research works in which some human tissue kallikreins are expressed in salivary glands. In the present study, the main goal was to determine expression of human tissue kallikreins 4, 8, 10, 11 and 13 ...
متن کامل1,3-Bis[(4-nitrobenzylidene)aminooxy]propane
The complete molecule of title compound, C(17)H(16)N(4)O(6), is generated by a crystallographic twofold axis. Within the mol-ecule, the two benzene units are approximately perpen-dicular, making a dihedral angle of 85.91 (4)°. In the crystal, mol-ecules are linked into a three-dimensional network by C-H⋯O hydrogen bonds and short O⋯O and N⋯O inter-actions, with distances of 2.998 (2) and 2.968 ...
متن کاملPropane-1,3-diyl bis(4-aminobenzoate)
Mol-ecules of the title compound, C(17)H(18)N(2)O(4), lie on a twofold rotation axis that passes through the central methyl-ene C atom. The mol-ecules adopt a 'V' shape and the trimethyl-ene unit assumes a gauche-gauche conformation. The amino N atom shows a nonplanar coordination. Adjacent mol-ecules are connected by N-H⋯O hydrogen bonds into chains running along [001]. Furthermore, N-H⋯N hydr...
متن کاملPropane-1,3-diyl bis(pyridine-4-carboxylate)
The title compound. C(15)H(14)N(2)O(4), (I), has a gauche-gauche (O/C/C/C-O/C/C/C or GG) conformation and is a positional isomer of propane-1,3-diyl bis-(pyridine-3-carboxyl-ate), (II). The mol-ecule of (I) lies on a twofold rotation axis, which passes through the central C atom of the aliphatic chain, giving one half-mol-ecule per asymmetric unit. There is excellent agreement of the geometric ...
