title: Immunoenhancing activity of NPT 15392: a potential immune response modifier.
abstract: NPT 15392, a new immunomodulating compound related to inosine in structure and isoprinosine in action, enhances T-cell dependent immune responses. Antibody responses to sheep red blood cells are augmented two to threefold in mice receiving NPT 15392 while T-cell independent antibody responses to TNP-LPS are unaffected. NPT 15392 does not enhance or alter the number of clonable B cells. This drug also increases cytotoxic T-lymphocyte responses to allogeneic tumor cells but does not alter the number of cytotoxic precursor cells. Immature hematopoietic cell classes (clonable progenitor cells) were also monitored and found not to be influenced by NPT 15392.
