Steroid tetrol solid state forms
View Patent ↗The invention relates to solid state forms of androst-5-ene-3β,7β,16α,17β-triol, formulations containing or prepared from such solid state forms and use of such materials for modulating acute and chronic non-productive inflammation. The formulations can be used to prevent, treat or slow the progression of conditions related to autoimmunity such as arthritis, multiple sclerosis, ulcerative colitis or Type 1 diabetes. The formulations can also be used to prevent, treat or slow the progression of conditions related to metabolic disorders such as Type 2 diabetes.
1. A product wherein the product is a solid state form of androst-5-ene-3β,7β,16α,17β-tetrol obtained by the process comprising (1) obtaining purified androst-5-ene-3β,7β,16α,17β-tetrol, and (2) recovering androst-5-ene-3β,7β,16α,17β-tetrol from aqueous acetonitrile.
2. The product of claim 1 characterized by:
(a) an X-ray powder pattern with 2-theta values of about 15.9, 17.3 and 19.2 and optionally one or more 2-theta values of about 7.4, 14.8, 20.4, 24.4, 27.4 and 29.4 and (b) with differential thermal analysis spectrum with a heating rate of 10° C./min having an endothermic transition centered at about 204° C. (onset at about 194° C.) optionally with an endotherm transition centered at about 98° C. or 224° C.
3. The product of claim 1 characterized by
(a) an X-ray powder pattern with 2-theta values of about 15.9, 17.3 and 19.2 and optionally one or more 2-theta values of about 7.4, 14.8, 20.4, 24.4, 27.4 and 29.4 and (b) a solid state infrared Raman spectrum with peaks at about 1670 cm −1 , 1462 cm −1 and 1439 cm −1 .
4. A composition comprising one or more excipients and a solid state form of androst-5-ene-3β,7β,16α,17β-tetrol obtained by the process comprising (1) obtaining purified androst-5-ene-3β,7β,16α,17β-tetrol, and (2) recovering androst-5-ene-3β,7β,16α,17β-tetrol from aqueous acetonitrile.
5. A method of preparing a liquid formulation comprising admixing a solid state form of androst-5-ene-3β,7β,16α,17β-tetrol, obtained by the process comprising (1) obtaining purified androst-5-ene-3β,7β,16α,17β-tetrol, and (2) recovering androst-5-ene-3β,7β,16α,17β-tetrol from aqueous acetonitrile, with a liquid excipient.
6. A method of treating an inflammation condition or disease comprising administering an effective amount of a solid formulation to a subject in need thereof wherein the formulation comprises a solid state form of androst-5-ene-3β,7β,16α,17β-tetrol obtained by the steps (1) obtaining purified androst-5-ene-3β,7β,16α,17β-tetrol, and (2) recovering androst-5-ene-3β,7β,16α,17β-tetrol from aqueous acetonitrile.
7. The method of claim 6 wherein the inflammation condition or disease is a chronic, non-production inflammation condition or disease.
8. The method of claim 6 wherein the condition or disease is an autoimmune condition or disease.
9. The method of claim 6 wherein the condition or disease is a metabolic condition or disease.
10. The disease of claim 8 wherein the autoimmune disease is Type 1 diabetes.
11. The method of claim 9 wherein the metabolic condition is hyperglycemia.
