PFKFB3 inhibit and methods of use as an anti-cancer therapeutic
View Patent ↗A novel compound, (E)-1-(pyridyn-4-yl)-3-(7-(trifluoromethyl)quinolin-2-yl)-prop-2-en-1-one, is provided herein. (E)-1-(pyridyn-4-yl)-3-(7-(trifluoromethyl)quinolin-2-yl)-prop-2-en-1-one is an inhibitor of 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) with surprisingly superior efficacy and pharmacodynamic properties in vitro and in vivo. Also provided are pharmaceutical compositions including the compound and methods of use of the compound in treating cancer and tumors in vivo, as well as inhibiting glycolytic flux and PFKFB3 enzymatic activity in cells.

2. The pharmaceutical composition of claim 1 , wherein the cyclodextrin is sulfobutyl ether beta cyclodextrin.
3. The pharmaceutical composition of claim 1 , further comprising mannitol.
4. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition is an aqueous solution or a lyophilate.
5. An aqueous pharmaceutical composition comprising:
(E)-1-(pyridyn-4-yl)-3-(7-(trifluoromethyl)quinolin-2-yl)-prop-2-en-1-one or a pharmaceutically acceptable salt thereof; and
sulfobutyl ether beta cyclodextrin.
6. The aqueous pharmaceutical composition of claim 5 , wherein the (E)-1-(pyridyn-4-yl)-3-(7-(trifluoromethyl)quinolin-2-yl)-prop-2-en-1-one or pharmaceutically acceptable salt thereof has a concentration of 5 mg/ml.
7. The aqueous pharmaceutical composition of claim 6 , wherein the sulfobutyl ether beta cyclodextrin has a concentration of 30% w/v.
8. The aqueous pharmaceutical composition of claim 7 , wherein the composition has a pH of 3.5.
9. The aqueous pharmaceutical composition of claim 7 , wherein the composition has a pH of 3.0.
10. A lyophilized pharmaceutical composition comprising:
(E)-1-(pyridyn-4-yl)-3-(7-(trifluoromethyl)quinolin-2-yl)-prop-2-en-1-one or a pharmaceutically acceptable salt thereof; and
a cyclodextrin selected from the group consisting of sulfobutyl ether beta cyclodextrin and beta cyclodextrin.
11. The lyophilized pharmaceutical composition of claim 10 , wherein the cyclodextrin is sulfobutyl ether beta cyclodextrin.
