OBJECTIVE IM862 is a synthetic dipeptide (L-glutamine L-tryptophan) with in vitro and in vivo antiangiogenic properties. Phase I/II studies showed minimal toxicity and a response rate of 36% in AIDS-Kaposi's sarcoma. We report a 24-week, randomized, double-blinded, placebo-controlled phase III trial

Knowledge of the amino acid requirements of a neoplasm is valuable in determining optimal nutritional support and antineoplastic therapy for the tumor-bearing host. The standard human tumor stem cell assay (HTSCA) was modified by reducing an individual amino acid below the normal plasma

The N-[p-(fluorosulfonyl)benzyl] derivatives of L-asparagine and L-glutamine (1a,b) were synthesized as potential inhibitors of L-asparagine synthetase (ASase). Condensation of p-(fluorosulfonyl)benzylamine (2) with the suitably protected amino acid in the presence of dicyclohexylcarbodiimide,

Myotubes prepared from the Japanese quail embryo at 9 days gestation were cultivated in the presence of glycyl-L-glutamine (Gly-Gln, beta-endorphin C-terminal dipeptide) or glycyl-glutamic acid (Gly-Glu), and changes in the activity of acetylcholinesterase (AChE) molecular forms and binding of

In the oral cavity, titanium is an excellent biocompatible material. However, it is reported that high ratios of intracellular titanium particles can cause cell apoptosis or necrosis by as-yet unknown mechanisms. The purpose of this study was to investigate the response of tumor necrosis factor

Eight new palladium complexes of the formula [Pd(bipy)(AA)]Cl 1 or 2 H2O (where bipy is 2,2'-bipyridine and AA is an anion of glycine, L-alanine, L-leucine, L-proline, L-serine, L-lysine, L-asparagine, or L-glutamine) have been synthesized by reaction of [Pd(bipy)Cl2] with an appropriate mono sodium

A study on the oncolytic activity of the L-cysteine derivative L-cysteine, ethyl ester, S-(N-methylcarbamate) monohydrochloride (NSC 303861), revealed that the drug caused complete regression of the MX-1 human mammary tumor xenograft. The compound also exhibited moderate antitumor activity against
