DOUBLE CHAIN PEPTIDE COMPOUNDS HAVING HEMOREGULATORY ACTIVITY

摘要

There is disclosed dipeptide compounds, the two peptide chains being joined together at a C alpha -atom of a non-terminal amino acid by a divalent bridging group -A-. The C alpha -atoms joined to group -A- are located in equivalent positions in each peptide chain and each lack their native alpha -side chain. Group -A- is as defined in claim 1. The bridged dipeptide compounds disclosed have a stimulating activity on cell division, especially for myelopoietic and bone marrow cells.
