A series of novel 5-arylidene-2-thioxoimidazolidin-4-ones were investigated as inhibitors of the lymphocyte-expressed pore-forming protein perforin. Structure-activity relationships were explored through variation of an isoindolinone or 3,4-dihydroisoquinolinone subunit on a fixed 2-thioxoimidazolidin-4-one/thiophene core. The ability of the resulting compounds to inhibit

Daily intragastric administration of a carcinogen N,N'-ethylenethiourea (ETU) (85 mg/kg body wt, congruent to 0.1 DL50) leads to significant polyadenylate polymerase (PAP) activity in rat blood serum by the 10th day of experiment. A similar course of N,N'-ethyleneurea (EU) fails

The acid-catalyzed cyclocondensation in refluxing acetonitrile of aqueous glyoxal with N-heteroaryl-N'-phenylureas 4a-f (heteroaryl = 2-thiazolyl, 2-pyrimidinyl,2-pyrazinyl, 2-pyridinyl, 3-pyridinyl and 2-benzimidazolyl) led to the formation of the corresponding 1-heteroaryl-3-phenyl-4,5-dihydroxy-2-imidazolidinones 5a-f. All the products were characterized by elemental and spectroscopic analyses. The

We describe the design and synthesis of a non-peptidic β-strand mimetic composed of alternating aryl and imidazolidin-2-one rings that can be adapted to display diverse side-chains. Solid- and solution-phase data together with calculations suggest that the desired conformation for side-chain

An efficient and versatile synthesis of novel exo-imidazolidin-2-one dienes is described. This involves the base-assisted condensation/cyclization cascade reaction of the monoimino derivatives of diacetyl with a series of isocyanates. This methodology enables preparation of symmetrical dienes, as long as the

The synthesis and the physico-chemical properties of four 3-(4-bromophenacyl)-5-arylidene-thiazolidine-2,4-diones, two 3-(4-bromobenzyl)-5-arylidene-thiazolidine-2,4-diones and seven 3-(4-chlorobenzyl)-5-arylidene-4-thio-imidazolidine-2-ones were described. These products were synthetized by the aldolisation-crotonisation reaction between aromatic aldehydes and substituted thiazolidinediones or thio-imidazolidinones.

A protocol for the palladium(0)-catalyzed amidation of heteroaromatic tosylates was successfully developed. The methodology proved to be effective for a variety of heteroaryl tosylates including the pyridine, pyrimidine, quinoline and quinoxaline ring systems. Successful carbon-nitrogen bond formation with these heteroaryl

Novel series of 1-(arenesulfonyl)imidazolidin-2-one (3a-i) and 1,3-bis(arenesulfonyl)imidazolidin-2-one (5a-i) have been synthesized and tested for their antitumor activity against 60 tumor cell lines taken from nine different organs. A significant inhibition for cancer cells was observed with series 5a-i compounds compared

Ethylenethiourea (ETU) is a potent teratogen in the rat but not in the mouse or any other species tested. Embryotoxic and teratogenic effects are produced in mice only after exposure to 10-40 times the teratogenic dose of ETU in rats.
