Description

COMPOUNDS AS MODULATORS OF BIS-PHOSPHOGLYCERATE MUTASE FOR THE
TREATMENT OF SICKLE CELL DISEASE
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application daims the benefit under 35 U.S.C. §119(e) of United States Provisional Application No. 63/077,973, fïled September 14, 2020, which is hereby incorporated by reference in its entirety.
FIELD
[0002] The présent disclosure relates generally to compounds, compositions, and method for treating sickle cell disease.
BACKGROUND
[0003] Bis-phosphoglycerate mutase (BPGM) is an enzyme in the glucose metabolism pathway that régulâtes the levels of 2,3-bis-phosphoglycerate (2,3-BPG) inside the red blood cell (RBC). 2,3-BPG is a known allosteric modulator of hemoglobin that stabilizes the de-oxy or “T-State” of hemoglobin that has a tendency to polymerize, resulting in the sickle cell morphology. There is currently a large unmet medical need for safe and effective oral thérapies for the treatment of sickle cell disease. BPGM modulators that lower 2,3-BPG levels offer a novel mechanism of action from existing thérapies and may significantly reduce sickling in sickle cell disease patients.
[0004] Accordingly, in one aspect, provided herein are compounds which are modulators of BPGM for use in treating sickle cell disease.

[0136] These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prévention of the action of microorganisms upon the subject compounds may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenyl sorbic acid and the like. It may also be désirable to include isotonie agents, such as sugars, sodium chloride and the like into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.
[0137] In some cases, in order to prolong the effect of a drug, it is désirable to slow the absorption of the drug from subeutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of ciystalline or amorphous material having poor water solubility. The rate of absorption of the drug then dépends upon its rate of dissolution, which in tum, may dépend upon crystal size and crystalline form. Altematively, delayed absorption of a parenterally-administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.
[0138] Injectable depot forms are made by forming microencapsule matrices of the subject compounds in biodégradable polymers such as polylactide-polyglycolide. Depending on the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodégradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions, which are compatible with body tissue.
