FR 113680: a novel tripeptide substance P antagonist with NK1 receptor selectivity.

Morimoto, H., Murai, M., Maeda, Y., Hagiwara, D., Miyake, H., Matsuo, M., ...

1. We have discovered a novel tripeptide substance P (SP) antagonist, FR 113680 [N alpha-[N alpha-(N alpha-acetyl-L-threonyl)-N'-formyl-D- tryptophyl]-N-methyl-N-phenylmethyl-L-phenylalaninamide]. In...

Pharmacological profile of a high affinity dipeptide NK1 receptor antagonist, FK888.

Fujii, T., Murai, M., Morimoto, H., Maeda, Y., Yamaoka, M., Hagiwara, D., ...

1. In our search for compounds that inhibit the binding of [3H]-substance P (SP) to guinea-pig lung membranes, the dipeptide SP antagonist, FK888, was developed by chemical modification of the parent...

Effect of intestinal microbiota on the induction of regulatory CD25+ CD4+ T cells

Ishikawa, H, Tanaka, K, Maeda, Y, Aiba, Y, Hata, A, Tsuji, N M, ...

When oral tolerance was induced in either specific pathogen-free (SPF) or germ-free (GF) mice, ovalbumin (OVA) feeding before immunization induced oral tolerance successfully in SPF mice. On the...

Phase I/II study of docetaxel and S-1 in patients with advanced gastric cancer

Yamaguchi, K, Shimamura, T, Hyodo, I, Koizumi, W, Doi, T, Narahara, H, ...

The aims of this phase I/II study of docetaxel and S-1 were to determine the dose-limiting toxicity (DLT), maximum-tolerated dose (MTD), and recommended dose (RD) in the phase I part and to explore...

Detection of peptide-specific CTL-precursors in peripheral blood lymphocytes of cancer patients

Maeda, Y, Hida, N, Niiya, F, Katagiri, K, Harada, M, Yamana, H, ...

Development of therapeutic vaccines is one of the major areas of tumour immunotherapy today. However, clinical trials of peptide-based cancer vaccines have rarely resulted in tumour regression. This...

UDP-Gal: βGlcNAc β1, 3-galactosyltransferase, polypeptide 3 (GALT3) is a tumour antigen recognised by HLA-A2-restricted cytotoxic T lymphocytes from patients with brain tumour

Tsuda, N, Nonaka, Y, Shichijo, S, Yamada, A, Ito, M, Maeda, Y, ...

Patient prognosis in the case of malignant brain tumours is generally poor, despite significant improvements in the early detection of the tumours, and thus the development of new treatment...
