Two separate studies were conducted using a continuous culture fermenter system to determine effects of supplementing D,L-methionine and various methionine derivatives on degradation of methionine by ruminal bacteria. A basal diet containing 20% alfalfa hay, 20% corn silage and 60% grain mix (DM basis) was provided at a rate of 75 g DM/d per fermenter and served as an unsupplemented control in ...

Cisplatin is one of the most successful compounds in the fight against cancer. Recently, interest was directed towards the development of cisplatin analogues which possess Nheterocyclic carrier ligands, coordinated to the cytotoxic platinum(II) moiety, instead of one or both of the am(m)ines. Hydantoins form a large group of derivatives widely applied in medicine and pharmacy, especially as ant...

The Red Sea sponge Hemimycale arabica afforded the known (Z)-5-(4-hydroxybenzylidene)-hydantoin (1), (R)-5-(4-hydroxybenzyl)hydantoin (2), and (Z)-5-((6-bromo-1H-indol-3-yl)methylene)-hydantoin (3). The natural phenylmethylene hydantoin (PMH) 1 and the synthetic (Z)-5-(4-(ethylthio)benzylidene)-hydantoin (4) showed potent in vitro anti-growth and anti-invasive properties against PC-3M prostate ...

In the title compound, C(15)H(17)ClN(2)O(4)S, the atoms in the hydantoin ring are coplanar (r.m.s. deviation = 0.006 Å). The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds which link the mol-ecules into centrosymmetric dimers. The dihedral angle subtended by the 4-chloro-phenyl group with the plane passing through the hydantoin unit is 82.98 (4)°. The cyclo-hexyl ring a...

In the title compound, C(10)H(9)FN(2)O(2), the dihedral angle between the hydantoin unit and the benzene ring is 65.55 (5)°. The atoms in the hydantoin ring are coplanar, with a mean deviation of 0.015 Å and a maximum deviation of 0.075 (2) Å for one carbonyl O atom. N-H⋯O hydrogen bonds link the mol-ecules into one-dimensional chains, with one carbonyl group acting as a bifurcated acceptor and...

BACKGROUND/AIM Neurofibromatosis 1-Noonan syndrome (NFNS) presents combined characteristics of both autosomal dominant disorders: NF1 and Noonan syndrome (NS). The genes causing NF1 and NS are located on different chromosomes, making it uncertain whether NFNS is a separate entity as previously suggested, or rather a clinical variation. PATIENTS AND METHODS We present a four-membered Greek fam...
