This invention relates to a compound in substantially pure form, selected from:
(a) alcohols having the following structural formulae 1 a, 1 b and 1c:
where for 1 a, R1 = H, and R2 = OH,
for 1b, R1 = R2 = H, and
for 1c, R1 = R2 = OH;
(b) phosphates having the following structural formulae 2a, 2b, and 2c:
where for 2a, R1 = H, and R2 = OH,
for 2b, R1 = R2 = H, and
for 2c, R1 = R2 = OH;
(c) esters of the phosphate function of the phosphates of (b) and further pyranone phosphates designated CL 1565-A, CL 1565-B, and CL 1565-T having the following structural formulae 3a, 3b, and 3c, respectively:
where for 3a, R' = H, and R2 = OH,
for 3b, R1 = R2 = H, and
for 3c, R1 = R2 = OH;
(d) acyl esters of the alcohols of (a) and of the pyranone phosphates of (c);
(e) the compound designated CL 1565-PT-3; and
(f) the pharmaceutically acceptable salts of the phosphates of (b), the pyranone phosphate esters of (c), the pyranone acyl esters of (d), and CL 1565-PT-3.
The invention also provides for the production of such compounds.
The compounds possess anti-tumor activity.
