WebMay 23, 2024 · Deaza-epothilone C, which incorporates a thiophene moiety in place of the thiazole heterocycle in the natural epothilone side chain, has been prepared by semisynthesis from epothilone A, in order to assess the contribution of the thiazole nitrogen to microtubule binding. The synthesis was based on the esterification of a known … WebIntermediate length alkyl side chains (nonyl and dodecyl) can selectively provide the β 1 or β 2 phase in solution and in semi-crystalline thin films, depending on the nature of the solvent used. For short side chains (hexyl) the β 2 phase forms more readily while for long side chains (pentadecyl) the β 1 phase is predominant.
WebNov 30, 2024 · Here we report a novel peptide stapling strategy based on the dithiocarbamate chemistry linking the side chains of residues Lys(i) and Cys(i + 4) of unprotected peptides and apply it to a series of dodecameric peptide antagonists of the p53-inhibitory oncogenic proteins MDM2 and MDMX. WebA new ligand (L) containing two nitro phenyl rings as side chains was synthesized. The reaction of this ligand with copper(II) and zinc(II) metal ions gave complexes with different coordination environments. The free ligand and the metal complexes were characterized using a number of spectroscopic m …
