13-desmethyl rhodopsin and 13-desmethyl isorhodopsin: visual pigment analogues.

The preparation and properties of three geometric isomers of 13-desmethyl retinal (13-dmr) are described. They are analogous to the all-trans, 11-cis, and 9-cis isomers of retinal since two of the cis isomers combine with cattle opsin to form pigments which are spectrally indistinguishable from rhodopsin and isorhodopsin and the all-trans isomer is unreactive.The pigment which resembles rhodops...

Stereoselective Synthesis and Biological Evaluation of C1-Epimeric and Desmethyl Monomeric Nuphar Analogues.

A class of monomeric nuphar analogues that are either epimeric at C1 and C1' or lack the naturally occurring methyl group at those positions were synthesized and evaluated for biological activity. The syntheses feature enantioselective vinylogous Mukaiyama-Mannich (vM-Mannich) reactions catalyzed by chiral phosphoric acids that proceed with excellent diastereoselectivity. Biological assays reve...

Synthesis of Bis-18,18'-desmethyl Ritterazine N.

Bis-18,18'-desmethyl ritterazine N has been prepared in enantiomerically pure form. The synthetic alkaloid, lacking only two of the 52 carbon atoms of the natural product, shows selective activity in the NIH 60 cell panel.

Tubulysin analogs incorporating desmethyl and dimethyl tubuphenylalanine derivatives.

A series of tubulysin analogs in which one of the stereogenic centers of tubuphenylalanine was eliminated were synthesized. All compounds were tested for antiproliferative activity towards ovarian cancer cells and for inhibition of tubulin polymerization. The dimethyl analogs were generally more active than the desmethyl analogs, and four analogs have tubulin polymerization IC(50) values simila...

Is the Fly Visual Pigment a Rhodopsin?

Rhodopsin, Insect Visual Pigment, Retinal, Thin Layer Chromatography, Xanthophyll Thin layer chromatography of retina extracts from Calliphora yielded, instead of retinal (or retinaloximes after N H 2OH treatment) a considerably more polar aldehyde or its corresponding oximes. That these compounds originate from the chromophoric group of the visual pigment was shown by the occurrence of differe...
