  Synthesis of 818-ethanoretinal and its interaction with apo-retinochrome

  摘要：

  All-(E)-8,18-ethanoretinal was synthesized from 2,2-dimethylcyclohexanone, and its binding experiment with apo-retinochrome afforded the new retinochrome analog, whose opsin shift exhibited fairly similar to that of the natural retinochrome.

  Retinoids and Related Compounds. 17. Conformational Study of Retinochrome Chromophore: Synthesis of 8,18-Ethanoretinal and a New Retinochrome Analog

  摘要：

  In order to investigate the chromophore conformation around the trimethylcyclohexene ring in retinochrome, (all-E)-8,18-ethanoretinal (2), in which C-8 and C-18 positions of retinal 1 was connected by an ethylene group, was synthesized via the Dieckmann condensation of diester 6 from 2,2-dimethylcyclohexanone 7. This analog 2 was incorporated into aporetinochrome, forming a pigment with lambda(max) at 498 nm. Its opsin shift (2200 cm(-1)) is of the same order of magnitude as that of native retinochrome (2400 cm(-1)), suggesting that the conformations of both chromophores are fairly similar in the protein. In addition, MMX calculations indicate that the torsional angle around the 6-7 single bond in retinochrome might correspond to the allowable torsional angle in 8,18-ethanoretinal (2).

  11Z-8, 18-Ethanoretinal was synthesized from the β-ionone alaog (5) via the Witting reaction, and its binding experiment with bovine opsin afforded the new rhodopsin analog, whose opsin shift and CD spectrum were similar to those of the native rhodopsin.
