Synthesis and investigation of the possible insulin-like activity of 1d-4-O- and 1d-6-O-(2-amino-2-deoxy-α-d-glucopyranosyl) myo-inositol 1-phosphate and 1d-6-O-(2-amino-2-deoxy-α-d-glucopyranosyl) myo-inositol 1,2-(cyclic phosphate)

The synthesis of the glycosyl-myo-inositol 1-phosphates 1 and 2 and of the glycosyl-myo-inositol 1,2-(cyclic phosphate) 3, starting from previously synthesized intermediates, is reported. Compound 3 was found to display proliferative effects on the early developing inner ear of chick embryo.
