| Description
| - Chiral recognition of bilirubin IX-a, biliverdin IX-a, and bilirubin ditaurate dianions by cyclodextrins was studied using a combination of vibrational and electronic circular dichroism. Biliverdin forms inclusion complexes with b-cyclodextrin and b-methylcyclodextrin. Bilirubin bonds to both cyclodextrins by means of hydrogen bonds and only shallow inclusions that are restricted by the presence of COO- in the pigment structure. Bilirubin ditaurate complexes are realized by a weak inclusion of the whole molecule, or some part of it, into the cyclodextrin cavity and stabilization of the conformation by hydrogen bonds. Bilirubin and bilirubin ditaurate can be recognized by cyclodextrin and methylcyclodextrin in the form of opposite conformers. Spectroscopic characteristics of the different conformations of the bile pigments were obtained for the first time by vibrational circular dichroism techniques.

- Metodami vibračního a elektronového cirkulárního dichroismu bylo studováno chirální rozpoznávání dianiontů bilirubinu IX-a, biliverdinu IX-a, a ditaurátu bilirubinu a cyklodextriny. Biliverdin tvoří s b-cyclodextrinem and b-methylcyclodextrinem inkluzní komplexy. Bilirubin se váže k oběma cyklodextrinům vodíkovými vazbami, které jsou podmíněny přítomností skupin COO- ve struktuře barviva. Komplex ditaurátu bilirubinu vniká slabou inkluzí celé molekuly nebo její části do dutiny cyklodextrinu a konformace je stabilizovaná vodíkovými vazbami. Bilirubin a ditaurát bilirubinu jsou rozpoznávány cyklodextrinem a methylcyklodextrinem ve formě opačných enantiomerů. Poprvé byly získány charakteristické signály konformací studovaných barviv ve spektrech vibračního cirkulárního dichroismu. (cs)
