Millimeter-wave spectroscopy of hydantoin, a possible precursor of glycine
Context. Hydantoin (Imidazolidine-2, 4-dione, C3H4N2O2) is a five-membered heterocyclic compound that is known to arise from prebiotic molecules such as glycolic acid and urea, and to give the simplest amino acid, glycine, by hydrolysis under acidic ...

THE NON-AVAILABILITY OF LYSINE FROM THE CORRESPONDING HYDANTOIN IN THE RAT
The hydantoin of lysine was fed to rats on a lysine-free diet and was shown to have no growth promoting effect. This hydantoin, therefore does not appear to give rise to the corresponding α-amino acid in contrast with results obtained elsewhere with ...

Overexpression and characterization of hydantoin racemase from Agrobacterium tumefaciens C58 [PDF]
Hydantoin racemase enzyme together with a stereoselective hydantoinase and a stereospecific D-carbamoylase guarantee the total conversion from D,L-5-monosubstituted hydantoins with a low velocity of racemization to optically pure D-amino acids. In this

Modulation of multidrug efflux pump activity by new hydantoin derivatives on colon adenocarcinoma cells without inducing apoptosis [PDF]
Background: Hydantoin derivatives are very promising candidates to improve the efficacy of anticancer chemotherapy. Previously, we demonstrated that eight hydantoin derivatives inhibited the P-glycoprotein (ABCB1) efflux pump of mouse T-lymphoma cells ...
