5-Benzylidene-2-thiohydantoin (1) and 5,5-dimethyl-2,4-dithiohydantoin (6) undergo Mannichreaction with formaldehyde and morpholine to give the corresponding Mannich products 2 and 7, respectively. Subsequent reaction of the product 2 and 7 with phenacyl bromide gives the corresponding 2-benzolmethylthiohydantoin Reaction of 5-benzylidene-2-carbomethoxythiohydantoin (5b) with P2S5 afforded 4-benzylideneimidazo[2

2-Selenoimidazolidin-4-ones and 2-selenoimidazol-4-ones containing phenylor pyridylmethylidene substituent at position 5 were synthesized. The structure of 3-benzyl-2-selenohydantoine was confirmed by X-ray crystallography. A series of 2-(methylseleno)imidazol-4-ones was obtained by alkylation of 3,5-disubstituted selenohydantoines with methyl iodide. The synthesized selenohydantoines and 3-benzyl-5-pyridylmethylidene-2-(methylseleno)imidazol-4-ones were examined in the complexation reactions with CoCl2, NiCl2, CuCl2, and CuI(CH3CN)4ClO4; electrochemical investigations showed that reduced forms of the copper-containing complexes were stable

Novel variously substituted thiohydantoin-based dispiro-indolinones were prepared using a regio- and diastereoselective synthetic route from 5-arylidene-2-thiohydantoins, isatines, and sarcosine. The obtained molecules were subsequently evaluated in vitro against the cancer cell lines LNCaP, PC3, HCTwt, and HCT(-/-). Several compounds demonstrated a relatively high cytotoxic activity vs. LNCaP cells

Various 5-arylidene-2-thiohydantoins, N3-substituted and/or S-substituted or not, were synthesized by aldolisation-crotonisation reaction from aromatic aldehydes or cyclic ketones and 2-thiohydantoins. These products, largely original, prepared as potentially active on chronic inflammatory diseases involving cellular-mediated immunity, display immunosuppressive activity which, however, remains clearly lower than ciclosporine's one. Searched in a few cases, anticancer activity is not obviously detected for any of tested products.

A method has been developed for the preparation of a new type of dispiro derivative, 5''-bromo-2-[(4-chlorophenyl)sulfanyl]-1'-methyl-1,4'-diphenyldispiro[imidazole-4,3'-pyrrolidine-2',3''-indoline]-2'',5(1H)-dione, starting from 2-thiohydantoin and using a 1,3-dipolar cycloaddition reaction. The configuration of the target dispiro derivative was unambiguously established by physicochemical methods.
