Hydantoin and hydrogen-bonding patterns in hydantoin derivatives [PDF]
Acta Crystallographica Section C Crystal Structure Communications, 2004 The structure of hydantoin (imidazolidine-2,4-dione), C3H4N2O2, has been determined from a twinned crystal. The two carbonyl bond lengths are nearly equal, even though one of them adjoins electron-donating NH groups to either side while the other is adjacent to only one.

Revisiting the SAR of the antischistosomal aryl hydantoin (Ro 13-3978) [PDF]
, 2016 The aryl hydantoin 1 (Ro 13-3978) was identified in the early 1980s as a promising antischistosomal lead compound. However, this series of aryl hydantoins produced antiandrogenic side effects in the host, a not unexpected outcome given their close ...

Identification of a novel class of autotaxin inhibitors through cross-screening [PDF]
, 2015 Three novel series were generated in order to mimic the pharmacophoric features displayed by lead compound AM095, a Lysophosphatidic acid (LPA1) receptor antagonist. Biological evaluation of this array of putative LPA1 antagonists led us to the discovery
