p300 and its paralog CBP can acetylate histones and other proteins and have been implicated in a number of diseases characterized by aberrant gene activation, such as cancer. A novel, highly selective, orally bioavailable histone acetyltransferase (HAT) domain inhibitor has been identified through virtual ligand screening and subsequent optimization of a unique hydantoin screening hit. Conforma...
The 41 novel acylthiourea derivatives with hydantoin were synthesized in moderate to excellent yields by using 5-(4-aminophenyl)- and 5-(4-aminobenzyl)-hydantoin or 5-(4-aminobenzyl)-thiohydantoin as raw materials and characterized by IR, 1H NMR spectra and elementary analysis. The preliminary bioassay showed that these compounds exhibit certain selectively herbicidal activities with the 91%, 9...
The title compound, 3-amino-5-methyl-5-(4-pyrid-yl)imid-azol-idine-2,4-dione, C(9)H(10)N(4)O(2), was obtained by reaction of 5-methyl-5-(4-pyrid-yl)hydantoin with hydrazine. It crystallizes as a racemate in the tetra-gonal space group I4(1)/a with one mol-ecule in the asymmetric unit. The dihedral angle between the pyridine ring and the five-membered hydantoin ring is 47.99 (3)° In the crystal ...
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...
a mild and efficient one-pot three-component and environmentally benign approach for the synthesis of a wide range of hydantoin annulated derivatives has been described. a multi-component reaction between a carbonyl compounds (ketone or aldehyde), potassium cyanide and ammonium carbonate (as cyanating agent and amine source, respectively leads to the formation of hydantoins. the proposed optimi...
Fluorous diastereomeric mixture synthesis (FDMS) is introduced and demonstrated in the synthesis of six diastereomers of hydantoin-fused hexahydrochromeno[4,3-b]pyrroles.
Methoxymethylation of a variety of alcohols was performed using formaldehyde dimethyl acetal in the presence of 1,3-dichloro-5,5-dimethyl hydantoin [DCDMH] and Poly N,N′-dibromo-N-ethyl naphthyl-2,7-disulfonamide [PBNS] as catalysts at room temperature and under solvent-free conditions. Our experiments show that primary and secondary alcohols can be smoothly converted into the corresponding MOM...
