The invention relates to iron(III) complex compounds and pharmaceutical compositions comprising them for the use as medicaments, in particular for the treatment and/or prophylaxis of iron deficiency symptoms and iron deficiency anemias.
Alkylidene acetoacetamides are useful building blocks for the preparation of a number of biologically active derivatives, including dehydro-β-amino-acid-containing peptidomimetics. A one-pot two-step protocol for the preparation of amino-acid-derived unsaturated acetoacetamides has been optimized. The use of microwave activation avoids, or at least decreases, the need for catalysts in both steps. A

participate in both hydrogen bonds and n→π* interactions, these two interactions likely affect one another. Herein, enhancement of an amidic n→π* interaction is shown to reduce the ability of β-keto amides to tautomerize to the enol, indicating decreased hydrogen-bonding capacity of the amide carbonyl group. Thus, an n→π* interaction can have a significant effect on the strength of a hydrogen bond to the same
A series of conformationally flexible and restricted dimers of monastrol as well as related dihydropyrimidones have been synthesized by employing one-pot Biginelli multicomponent reaction. These dimers have been evaluated for cytotoxic potency against selected human cancer cell lines and some of the compounds have exhibited more cytotoxic potency than the parent monastrol. Further. the DNA binding ability by thermal denaturation studies and antimicrobial activities of these compounds are also discussed. (C) 2011 Elsevier Masson SAS. All rights reserved.
