Isomerization of all-trans-retinoic acid to 9-cis-retinoic acid.

The discovery of the biological activity of 9-cis-retinoic acid raises questions as to its mode of biosynthesis. A simple mechanism involves the direct isomerization of all-trans-retinoic acid to 9-cis-retinoic acid. It is shown here that bovine liver membranes, but not supernatant fractions, can isomerize all-trans-retinoic acid into 9-cis-retinoic acid and 13-cis-retinoic acid. The concentrat...

Isomerization of trans-diethylstilbestrol to pseudo-diethylstilbestrol.

This study reports the formation and isolation of a diethylstibestrol-dimethylsulfoxide (DES-DMSO) adjunct and Z-3, 4-di (p-hydroxyphenyl)-2-hexene (psi-DES) from trans-DES. The presence of psi-DES was indicated by NMR and mass spectrometry and confirmed by direct comparison to a reference sample. High resolution NMR (360 MHz) along with the comparison of the chemical shift values of methine an...

Trans-cis isomerization and the blue phases.

A new class of photoactive chiral liquid crystals based on a photoactive nematic host material and a photoinactive chiral dopant was utilized to investigate the behavior of the blues phases when trans-cis isomerization is induced. While the general behavior follows what has been observed in the cholesteric phase, the sensitivity of the blue phases to external parameters causes different behavio...

Temperature dependence of the IR driven cis-trans isomerization of nitrous acid (HONO).

With the help of ultrafast time-resolved infrared spectroscopy, we investigate the temperature dependence of the IR driven cis-->trans isomerization of nitrous acid (HONO) in solid Kr. We find that the lifetime of the OH-stretch vibration, as well as the final cooling into the matrix, is affected only minimally (if at all) by temperature. Nevertheless, the quantum yield of the cis-->trans isome...

Density functional theory study of the trans-trans-cis (TTC)-->trans-trans-trans (TTT) isomerization of a photochromic spiropyran merocyanine.

Density Functional Theory (DFT) calculations have been performed on the TTC-->TTT isomerization reaction of the open forms of the 1',3'-dihydro-8-bromo-6-nitro-1',3',3'-trimethylspiro[2H-1-benzopyran-2,2'-(2H)indole (8-Br-6-nitro-BIPS) system. The calculations were carried out in vacuo and in methylene chloride solution at different temperatures. Results are compared with the available experime...
