A series of 5,5-disubstitutedhydantoin derivatives was synthesized by alkylating 5,5-bis(mercaptomethyl)-2,4-imidazolidinedione (3) with various halomethylaromatic or halomethylheteroaromatic precursors, or by using the Buchener-Berg procedure on the required ketone. When evaluated for their ability to inhibit HIV-induced cell killing and virus production in CEM or MT-2 cells only compounds 2, 4n
Exploring the interest of 1,2-Dithiolane ring system in peptide chemistry. Synthesis of a chemotactic tripeptide and x-ray crystal structure of a 4-amino-1,2-dithiolane-4-carboxylic acid derivative
Due to their relevant biological functions and specific chemical reactivity 1,2-dithiolanes (five-membered cyclic disulfides) represent an emerging class of heterocyclic compounds. However, despite the extensive research centered on lipoic acid and its analogues, only very few data are at the present available on peptides containing this ring system. We report here synthesis, conformation and bioactivity of a fMLF-OMe analogue, namely For-Met-Adt-Phe-OMe (7), in which the residue of the 4-amino-1,2-dithiolane-4-carboxylic acid (Adt) (4) replaces the central L-leucine. The crystal conformation of the synthetic intermediate Boc-Adt-OMe (5) is also described and compared to that of lipoic acid (R-1,2-dithiolane-3-pentanoic acid) (3) and asparagusic acid (1,2-dithiolane-4-carboxylic acid) (2).

This series of 5,5-disubstituted Hydantoin derivatives are biologically active in their ability to inhibit HIV-induced death and virus production in mammalian (human) cells.(FR) Série de dérivés d'hydantoïnes disubstituées en 5,5 synthétisées par alkylation de 5,5-bis(thiométhyl)-2,4-imidazolidinedione avec des précurseurs aromatiques d'halométhyle ou hétéroaromatiques d'halométhyle ou par la procédure Buchener-Berg sur la cétone requise. Cette série de dérivés d'hydantoïnes disubstituées en 5,5 est biologiquement active pour inhiber la mort induite par le VIH et la production virale dans les cellules de mammifères (humaines).
