Description

Application

Suitable for inhibition of various mammalian alkaline phosphatase (i.e., liver, kidney, placenta, bone and tumor).
Intestinal alkaline phosphatases are only slightly inhibited.
Not for veterinary use.

Biochem/physiol Actions

Shows both immunostimulant and immunosuppressant effects, depending on several controllable factors. Very effective in treatment of ascariasis (hookworm infestation). Useful in chemotherapy of colorectal cancers, possibly due to its stimulation of IL-1 production and direct activation of macrophages.

Other Notes
