 TI    Treatment with the alpha-glucosidase 1 inhibitor 6-O-butanoyl
       castanospermine reduces the detection of LFA-1 (CD18/CD11a) by
       monoclonal antibodies.

 AB    The antiviral clinical candidate 6-O-butanoyl castanospermine (MDL
       28,574), an alpha-glucosidase 1 inhibitor, was examined for its effect
       on elementary parameters of immune function. It did not affect the
       mitogenic response of uninfected human mononuclear leukocytes or the
       detection of a range of cell surface markers, with the exception of the
       integrin LFA-1 (CD18/CD11a), which was reduced, after cell growth in
       vitro. The detection of LFA-1 was also reduced on both human and murine
       cells after oral administration of the compound to xenochimaeric or
       normal mice, respectively. Altered LFA-1 expression or function may
       contribute to reduced cell adhesion and the observed reduction in the in
       vitro allogeneic response by uninfected cells, as well as the previously
       described prevention of cell conjugate and HIV-induced syncytium
       formation.
