Dipeptide compounds are disclosed, 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 and each lack their native .alpha.-side chain. The bridged dipeptide compounds disclosed have a stimulating activity on cell division, especially for myelopoietic and bone marrow cells.
披露了二肽化合物,两个肽链通过一个二价桥接基团--A--在非末端
氨基酸的C.alpha.-原子上连接在一起。连接到基团--A--的C.alpha.-原子在每个肽中位于等效位置,并且每个都缺少其原始的.alpha.-侧链。所披露的桥接二肽化合物对细胞分裂具有刺激作用,特别是对于髓系和骨髓细胞。
