1-Acetyl-5-meth­oxy-4-(phenyl­sulfan­yl)imidazolidin-2-one

The title compound, C12H14N2O3S, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The five-membered imidazolidin-2-one rings in both mol-ecules are twisted about the C-C bond. In the crystal, the A and B mol-ecules are associated via pairs of N-H⋯O hydrogen bonds, forming A-B dimers. These dimers are linked via C-H⋯S hydrogen bonds, forming double dimers, which are...

New imidazolidinic bioisosters: potential candidates for antischistosomal drugs.

The emergence of strains of Schistosoma resistant to praziquantel has drawn attention to the search for new schistosomacide drugs. Imidazolidinic derivatives have performed outstandingly against adult S. mansoni worms when evaluated in vitro. The molecular modification of imidazolidine by way of bioisosteric replacement gives rise to variations in its biological response. This study verifies th...

Structural diversity of copper(II) complexes with N-(2-pyridyl)imidazolidin-2-ones(thiones) and their in vitro antitumor activity.

Six series of structurally different mono- and binuclear copper(II) complexes 5-10 were obtained by reacting N-(2-pyridyl)imidazolidin-2-ones (1a-l), N,N'-bis(2-pyridyl)imidazolidin-2-ones (2a,b), N-acyl-N'(2-pyridyl)imidazolodin-2-ones (3a-j) and N-(2-pyridyl)imidazolidine-2-thiones (4a-g) with copper(II) chloride at an ambient temperature. The coordination modes of the complexes obtained were...

Imidazolidin-4-one derivatives of primaquine as novel transmission-blocking antimalarials.

Imidazolidin-4-one derivatives of primaquine were synthesized as potential double prodrugs of the parent drug. The title compounds inhibit the development of the sporogonic cycle of Plasmodium berghei, affecting the appearance of oocysts in the midguts of the mosquitoes. The imidazolidin-4-ones are very stable, both in human plasma and in pH 7.4 buffer, indicating that they are active per se. T...
