Synthesis and cytotoxicity of platinum(II) complexes of 3-aminocyclopentanespiro-5-hydantoin and 3-aminocycloheptanespiro-5-hydantoin.
Four new platinum(II) complexes of 3-aminocyclopentanespiro-5-hydantoin (acpsh) and 3-aminocycloheptanespiro-5-hydantoin (achpsh) were synthesized and characterized by elemental analysis, IR and 1NMR spectra. The spectral analyses indicated a cis-square planar structure of the complexes with ligands coordinated via the NH2 group. The complexes were evaluated for in vitro cytotoxicity in murine ...
متن کاملUrinary metabolites of cis-9,10-methylene octadecanoic acid. cis-3,4-Methylene hexanedioic acid and related compounds.
cis-3,4-Methylene hexanedioic acid has been discovered in human urine. It has been isolated and identified by mass spectrometry and synthesis. The daily excretion in nine subjects on a free diet was 88 mumol/day (range, 32 to 144 mumol/day). cis-3,4-Methylene hexanedioic acid was given orally to a rat. About 90% of the dose was recovered unchanged in the urine within 24 h. Intragastric administ...
متن کاملPoly(methylene blue) modi®ed electrode sensor for haemoglobin
Poly(methylene blue) modi®ed electrodes have been prepared by potential cycling from aqueous electrolyte solution containing methylene blue on glassy carbon substrates. They have been used successfully for the determination of haemoglobin via its electrooxidation at ®xed potential using the batch injection analysis technique in which whole blood samples diluted with phosphate or acetate buffer ...
متن کاملExpanding Phenotype of Fetal Hydantoin
subsequent birth of normal children occur frequently enough to be frustrating for those involved in the evaluation of malformed children and counseling of the parents. The fetal hydantoin syndrome, while a recognizable pattern of malformation in some patients,2 is not such a well defined entity as, for example, achondroplasia or Down syndrome is. It is not uncommon for one to see a child with s...
متن کامل3-Amino-5-methyl-5-(4-pyridyl)hydantoin
The title compound, 3-amino-5-methyl-5-(4-pyrid-yl)imid-azol-idine-2,4-dione, C(9)H(10)N(4)O(2), was obtained by reaction of 5-methyl-5-(4-pyrid-yl)hydantoin with hydrazine. It crystallizes as a racemate in the tetra-gonal space group I4(1)/a with one mol-ecule in the asymmetric unit. The dihedral angle between the pyridine ring and the five-membered hydantoin ring is 47.99 (3)° In the crystal ...
