A composition comprises: a base oil; an additive; and a drug. The additive has segments which are conjugated, e.g. covalently linked, together. A first segment facilitates solubility in the base oil, whereas a second segment facilitates drug solubility an

experimental part, p. 511 - 525 (2011/05/12)
In this study, carotenoid retinoates are described for the first time. The preparation was achieved by the azolide method. Various sec carotenols reacted with N-retinoylimidazol in the presence of catalytic amounts of sodium hydride. Mono- and diretinoates of (3R,3′R)-zeaxanthin and its (3S,3′S)- enantiomer, (9Z,9′Z; 3R,3′R)-alloxanthin, (3R,3′R)-7,8, 7′,8′-tetrahydro-3,3′-dihydroxy-β,β-carotene-8, 8′-dione and (3R,6R,3′R,6′R)-ε,ε-carotene-3, 3′-diol (lactucaxanthin), as well as monoretinoates of (3R,3′RS,6′R)-3′-methoxy-β,ε-caroten-3-ol, (3R,3′RS,6′R)-3-methoxy-β,ε-caroten-3′-ol, (2R,6′RS)-β,ε-caroten-2-ol, (3R,3′S; meso)-astaxanthin and (2′R)-aleuriaxanthin are reported in this study. Spectroscopic properties (1H-NMR mass spectrometry, visible and circular dichroism spectra) are discussed. Studies on other carotenoid derivatives with two chromophores are referred to here.

Novel hybrid vitamin, 3-O-retinoyl-L-ascorbic acid (3a) was conveniently prepared by reaction of sodium L-ascorbate with retinoyl fluoride. The 3-O-acylated structure was confirmed by the comparison of spectral data of its methylated compound with those of 3-O-methyl-2-O-retinoyl-L-ascorbic acid (20) prepared from 5,6-O-isopropylidene-3-O-methyl-L-ascorbic acid. 3-O-Retinoyl-L-ascorbic acid (3a) showed a reducing activity against the stable radical, α,α-diphenyl-β-picrylhydrazyl (DPPH).

, p. 1029 - 1033 (2007/10/02)
A series of anhydrides of isomeric retinoic acids, which are biologically active retinoids, were synthesized.It was shown that three alternative methods can be used for the synthesis of the symmetrical anhydride of all-(E)-retinoic acid.Decomposition of t
