1,3-Dialkyl-4,5-imidazolidinediones (5) were prepared by the reaction of oxalyl chloride (3) with the corresponding 1,3,5-trialkyl-hexahydro-1,3,5-triazines (4), followed by addition of ethanol, in good to fair yields and fully characterized by MS, IR, H-1 and C-13 NMR.

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.
