2,5-Bis[(3-hydroxypropyl)amino]-1,4-benzoquinone monohydrate

چکیده
The title compound, C(12)H(18)N(2)O(4)·H(2)O, was obtained as a product of the reaction of hydro-quinone with n-propanol amine. The compound crystallizes as a monohydrate, integrating water into its hydrogen-bonded network. Each diamino-quinone moiety forms two centrosymmetric 10-membered rings through C=O⋯H-N bonds. The resulting bands along [102] are inter-linked through hy-droxy groups and water mol-ecules into three-dimensional network. The chemically equivalent bond lengths in the diamino-quinone moiety exhibit a perceptible discrepancy [e.g. C=O bond lengths differ by 0.016 (2) Å], apparently as a result of asymmetric hydrogen bonding: one O atom serves as an acceptor of one hydrogen bond, whereas the other is an acceptor of two.

A series of 3,6-substituted 2,5-bis(1-aziridinyl)-1,4-benzoquinone derivatives was shown to alkylate calf thymus DNA and to form DNA interstrand cross-links. Alkylation and cross-link formation were enhanced after electrochemical reduction of the compounds and increased with lower pH in the pH range from 4.5 to 8.0. Reduction especially shifts the pH at which cross-linking and alkylation occurs...
