Novel 9a,11-bridged azalides: One-pot synthesis of N'-substituted 2-imino-1,3-oxazolidines condensed to an azalide aglycone.
TLDR
An efficient one-pot method for the synthesis of novel 9a,11-bridged 15-membered 9a-aza-9-deoxo-9a-homoerythromycin A and its 6-O-methyl analogue has been developed and a mechanism for the formation of N'-substituted-2-imino-1,3-oxazolidines is discussed.
Novel thiosemicarbazone derivatives as potential antitumor agents: Synthesis, physicochemical and structural properties, DNA interactions and antiproliferative activity.
TLDR
Novel thiosemicarbazone derivatives clearly display stronger antiproliferative activity on five tumor cell lines than the reference compounds 3 and 4, which supports their further investigation as potential antitumor agents.
Synthesis and biological activity of 4''-O-acyl derivatives of 14- and 15-membered macrolides linked to omega-quinolone-carboxylic unit.
The synthesis and antimicrobial activity of a new class of macrolide antibiotics which consist of a macrolide scaffold and a quinolone unit covalently connected by an appropriate linker are
Synthesis and characterisation of thiosemicarbazonato molybdenum(VI) complexes and their in vitro antitumor activity.
TLDR
The characterisation of thiosemicarbazonato molybdenum(VI) complexes (1-4) in aqueous medium revealed that upon dissolving complexes in water, most likely to some extent dissociation took place, although experimental data didn't allow exact quantification of dissociation.
Vanadium-induced formation of thiadiazole and thiazoline compounds. Mononuclear and dinuclear oxovanadium(v) complexes with open-chain and cyclized thiosemicarbazone ligands.
TLDR
To the best of the authors' knowledge, compounds [V(2)O(3)(L(cycl))(2)(OR)(2)] represent the first structurally characterized dinuclear vanadium(v) complexes with a thiadiazole moiety acting as a bridging ligand.
Desmotropy, polymorphism, and solid-state proton transfer: four solid forms of an aromatic o-hydroxy Schiff base.
TLDR
This study reveals the significance of peripheral groups in the stabilization of metastable tautomers in the solid state by means of temperature-resolved powder X-ray diffraction and infrared spectroscopy.
Anion-directed self-assembly of flexible ligands into anion-specific and highly symmetrical organic solids.
TLDR
A solid-state study of two supramolecular complexes assembled by an anion-templated reaction of a flexible ligand L and anions with trigonal planar and tetrahedral geometry in methanol.
Two thiosemicarbazones derived from salicylaldehyde: very specific hydrogen-bonding interactions of the N-H...S=C type.
TLDR
The molecules in the crystal structures of (I) and (II) are linked into centrosymmetric R(2)(2)(8) dimers by hydrogen bonds of the N-H...S=C type, which are connected through pi-pi stacking and T-shaped C-H…pi interactions into three-dimensional networks.
N-Benzyloxy-1H-benzotriazole-1-carboxamide: a hydrogen-bonded tetramer based upon a rare R(4)4(20) structural motif.
The title compound, C(14)H(12)N(4)O(2), is the first example of a heterocyclic substituted hydroxamic derivative. The asymmetric unit consists of two molecules. The molecules are linked into
Bis{1-[N-(2-methoxyphenyl)iminomethyl]naphthalen-2(1H)-onato-kappa3O,N,O'}zinc(II) ethanol solvate.
In the crystal structure of the title compound, [Zn(C18H14NO2)2].C2H6O, the Zn atom displays a highly distorted octahedral coordination involving the O and N atoms of two molecules of the Schiff base
