Abstract

In the present review, we summarize our recent studies on the synthesis and spectral–kinetic parameters of photochromic retinals based on spiropyrans, diarylethenes, and a fulgimide and the use of these compounds for the preparation of artificial analogs of natural bacteriorhodopsin.

Abstract

The synthesis of retinal analogue series that contain a spyropyran moiety instead of a trimethylcyclohexene ring was proposed. The process of the retinal analogue interaction with bacterioopsin from apomembranes of Halobacterium salinarum and the spectral properties of the newly formed pigments were studied.

Abstract

A high diversity of tabulate corals in Eifelian deposits of the Syv“yu River basin (Subpolar Urals) is reported for the first time. Most of the corals are represented by colonies of syringoporids. Five new species Syringopora parva sp. nov., S. insueta sp. nov., S. indecora sp. nov., Tetraporinus syvjuensis sp. nov., and Armalites serotinus sp. nov. are described.

Abstract

A method for synthesis of retinal analogs labeled with electron-density groups is suggested. The interaction of these polyene compounds with bacterioopsin in apomembrane of Halobacterium salinarum was tested. A retinal analog containing a crown-ether receptor group is able to interact readily with bacterioopsin giving rise to rapid formation of a pigment with absorption maximum at 460 nm. This pigment is capable of undergoing cyclic photoconversion. The crown-bacteriorhodopsin photocycle is extremely slow and its quantum efficiency is very low (∼3% of that in native bacteriorhodopsin). This photocycle includes an M-like intermediate with a differential absorption maximum at 380 nm. A retinal analog in which the β-ionone ring is replaced by ferrocene moiety forms a stable chromoprotein with the main absorption band at 483 nm and a shoulder near 590-610 nm.
