Sonogashira cross-couplingreactions of 5-iodopyrimidine or 7-iodo-7-deazaadenine nucleosides with bile acid-derived terminal acetylenes linked via an ester or amide tether gave the corresponding bile acid–nucleoside conjugates. Analogous reactions of halogenated nucleosidetriphosphates gave directly bile acid-modified dNTPs. Enzymatic incorporation of these modified nucleotides to DNA was successfully
CDCl3—studied by means of concentration‐dependent 31P NMR spectroscopy experiments—and in aqueous solution, in which combined dynamic light scattering (DLS) and small‐angle neutron scattering (SANS) measurements provided a detailed physico‐chemical analysis of the self‐assembled systems, mainly organised in the form of large vesicles. Its ion‐transport properties throughphospholipidbilayers, determined
synthesized new types of ribbon type steroidal dimers derivedfrom three types of steroidal skeletons (cholicacid, etienic acid, estrone) using Cu(I) catalyzed 1, 3-dipolar cycloaddition reaction. Steroid parts of the molecular "ribbons" are linked by heterocyclic moiety, namely by 2,6-bis((1H-1,2,3-triazol-1-yl)-methyl)pyridine. Compounds synthesized possess different cytotoxic and hormone receptor modulating
