N-Hydroxythalidomide (1d), a potential metabolite of thalidomide (1a), was synthesized from N-phthalyglutaminic acid anhydride (1b) and O-tetrahydropyraline hydroxylamine, followed by deprotection. The teratogenicity of 1d was studied using the Hen's-Egg-Test model which had been found applicable for 1a. 1d was more teratogenic to chicken embryos compared to 1a. The percentage of teratogenic malformations in the 1d groups was 28-46%, whereas the percentage in the 1a groups was 20-23%. The… Expand

Investigation of N-hydroxythalidomide in vitro stability and comparison to other N-substituted derivatives.
TLDR
The stability of N-substituted derivatives of thalidomide was studied and compared to that of th Khalidomide itself and N-hydroxy compound, where the decrease in lipophilicity was not sufficient to affect the stability. Expand
Solid-phase synthesis of thalidomide and its analogues.
TLDR
A novel solid-phase synthesis of thalidomide and its metabolites and analogues is described, which involves the coupling of hydroxymethyl polystyrene with phthalic anhydride to form the resin-linked acid. Expand
Biological evaluation of both enantiomers of fluoro-thalidomide using human myeloma cell line H929 and others
TLDR
The first biological evaluation of fluoro-thalidomide in racemic and in both (R)- and (S)-enantiomerically pure forms against (in vitro) H929 cells of multiple myeloma (MM) using an annexin V assay is reported. Expand
Thalidomide in Human Immunodeficiency Virus (HIV) Patients
TLDR
The most important chemical and pharmacokinetic properties of thalidomide are reviewed, including recurrent aphthosis of nonviral and nonfungal origin in human immunodeficiency virus (HIV) patients, which is presently used as an experimental drug in the treatment of a variety of diseases with an autoimmune character.
