title: [The synthesis and immunosuppressive effects of steroid-peptide linkers].
abstract: Hydrocortisone was coupled with urotoxin tripeptide UTP-A, UTP-B and UTP-C respectively yielding 4 linkers. Their bioactivities such as prolongation of heterotopic transplanted cardiac tissue survival, inhibitory effects on phagocytosis of mouse peritoneal macrophages and the influence on Con A induced proliferation of spleen lymphocytes of mouse were observed. Compared with UTP-A, UTP-B, UTP-C or hydrocortisone the linkers were more potent immunosuppressants. The results suggest that the linker of steroid-peptide may simulate the permissive action.
