  • Unusual behavior of secondary amine group as a leaving group
    Publication

    - Year 2012

    In our recent project we focused on reactivity of2,2-dimethyl-4,6-dioxane-1,3-dione carbamoilo- and thiocarbamoylo- derivatives as a ketenesource. Meldrum`s acid derivatives after thermal decomposition gives substituted keteneswith stoichiometric yield, that can be trapped with various spectrum of nucleophiles likealcohols, thiols, amine, imines etc. In case of5-[3-(dimethylamino)-sulfanyl-propyliden]-2,2-dimethyl-1,3-dioxane-4,6-dione...

    - ORGANIC & BIOMOLECULAR CHEMISTRY - Year 2012

    Based on the benzo[b]naphtho[1,2-d]furan and benzo[b]naphtho[1,2-d]thiophene frameworks, a series of ligands with different basic side chains (BSCs) has been synthesized and pharmacologically evaluated. Also, their binding modes have been modelled using docking techniques. It was found that the introduction of a BSC in these systems brings about a decrease of affinity for both estrogen receptors α and β in an in vitro competitive...

  • Tmscl as a rate accelerating additive in acylations of amines with 5-(α-amino- α'-hydroxy)methylene meldrum's acids

    Aspects are presented of the acylation of amines, alcohols and thiols with 5-(α-amino- α'-hydroxy)methylene Meldrum's acids. We placed special emphasis on the acylation reaction of secondary amines with 5-(α-amino- α'-hydroxy)methylene Meldrum's acids, which, due to their basicity, caused problems concerning salt formation with a Meldrum acid derivative. We found that secondary amines, which react at the slowest rate and with a...

  • Tuftsin - new analogues and properties
    Publication

    - Postępy Biochemii - Year 2007

    Tuftsyna zbudowana z czterech reszt aminokwasowych (TKPR), jest najmniejszym endogennym immunomodulatorem występującym w naturze we krwi człowieka i innych ssaków. Została wyizolowana w 1970 roku na Uniwersytecie Tufts w Bostonie (USA) przez Najjara i Nishioka. Wykazuje ona działanie nie tylko immunostymulujące, ale również przeciwbakteryjne, przeciwwirusowe, przeciwnowotworowe oraz przeciwgrzybicze. W artykule opisano nowe właściwości...

  • TBAF Promoted Formation of Symmetrical Trisulfides
    Publication

    We have developed a new method for the synthesis of functionalized symmetrical trisulfides based on (5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorin-2-yl)disulfanyl derivatives prepared from readily available 5,5-dimethyl-2-sul-fanyl-2-thioxo-1,3,2-dioxaphosphorinane or bis(5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl) disulfide. The symmetrical trisulfides can be obtained from aliphatic and aromatic thiols andL-cysteine derivatives...
