In the asymmetric unit of the title organic-inorganic hybrid material, 2{H(3)[PW(12)O(40)]}·4C(3)H(4)N(2)O(2)·C(7)H(8)N(4)O(4)·21.5H(2)O, there are four crystallographically independent hydantoin mol-ecules, one dimerized hydantoin mol-ecule, viz. 1,1'-methyl-enebis(imidazolidine-2,4-dione, two independent H(3)PW(12)O(40) mol-ecules and 21.5 solvent water mol-ecules. Nine of the solvent water m...
متن کاملSynthesis of novel dihydropyridothienopyrimidin-4,9-dione derivatives.
A novel molecular scaffold, dihydropyridothienopyrimidin-4,9-dione, was synthesized from benzylamine or p-methoxybenzylamine in six steps involving successive ring closure to form a fused ring system composed of dihydropyridone, thiophene and pyrimidone. The pharmacological versatility of the dihydropyridothenopyrimidin-4,9-dione scaffold was demonstrated by inhibitory activity against metabotr...
متن کامل5-(4-Hydroxyphenyl)imidazolidine-2,4-dione
The title compound, C9H8N2O3, was prepared by reaction of phenol, glyoxylic acid and urea in water. The imidazolidine ring adopts an almost planar conformation (r.m.s. deviation = 0.012 Å) and is twisted by 89.3 (1)° relative to the benzene ring. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional framework.
متن کامل1-(4-Methoxyphenyl)imidazolidine-2,4-dione
In the title compound, C(10)H(10)N(2)O(3), the dihedral angle between the benzene and imidazolidine rings is 6.0 (4)°, consistent with an essentially planar mol-ecule. In the crystal, inter-molecular N-H⋯O hydrogen bonding between centrosymmetrically related mol-ecules leads to loosely associated dimeric aggregates. These are connected into a three-dimensional network by C-H⋯O inter-actions, as...
متن کاملMicrobiological Evaluation of 4-substituted-imidazolidine Derivatives
In the present studies, two series of 4-substituted-imidazolidines (IIIa-i and IIIj,k) were synthesized by reacting different tetrahydro-di-Schiff bases (IIa-i and IIj,k) with p-diethylaminobenzaldehyde/ dimethylaminobenzaldehyde. The title compounds were evaluated for their antibacterial and antifungal actions against some selected microbes. The results of microbiological evaluation revealed t...
