Suppression of human lymphocyte DNA and protein synthesis in vitro by adenosine and eight modified adenine nucleosides in the presence or in the absence of adenosine deaminase inhibitors, 2′-deoxycoformycin (DCF) and erythro-9-(2-hydroxy-3-nonyl) adenine (EHNA)

Abstract

Adenosine and eight modified adenine nucleosides in the presence or in the absence of adenosine deaminase (ADA) inhibitors, 2′-deoxycoformycin or erythro-9-(2-hydroxy-3-nonyl) adenine, were investigated with regard to their effects on phytohemagglutinin-stimulated human lymphocytes in vitro. Protein and DNA synthesis were inhibited depending upon the specific nucleoside, presence or absence of ADA inhibitor, and time of addition of nucleoside to cultures. A possible role for the modified adenine nucleosides in causing in vivo immunodeficiency is proposed.
