Abstract
Abstract The present invention relates to a method for inhibiting the phosphatidylinositol cycle in a cell by contacting the cell with certain myo-inositol analogs. Such myo-inositol analogs can also be utilized to treat phosphatidylinositol cycle-dependent conditions. The present invention also provides novel myo-inositol analogs.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
136 words
A method for inhibiting the phosphatidylinositol cycle in a cell which comprises contacting said cell with a compound represented by the formula I: ##STR17## wherein: R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is each independently selected from the group consisting of OH, F, N 3 , NH 2 , SH, SeH, Cl, Br, I and CN; with the proviso: (i) four or five of said R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are OH; and (ii) if said R 4 , R 5 or R 6 is F, Cl, Br or I then four of the said R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are OH.
Claim 2
Independent Claim
136 words
A method for inhibiting the phosphatidylinositol cycle in a cell which comprises contacting said cell with a compound represented by the formula I: ##STR17## wherein: R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is each independently selected from the group consisting of OH, F, N 3 , NH 2 , SH, SeH, Cl, Br, I and CN; with the proviso: (i) four or five of said R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are OH; and (ii) if said R 4 , R 5 or R 6 is F, Cl, Br or I then four of the said R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are OH.
