Methods and compositions to inhibit edema factor and adenylyl cyclase
View Patent ↗Fluorene-based molecules and their derivatives are described in compositions for the treatment of intestinal fluid loss.
1. A method of treating intestinal fluid loss in a subject, the method comprising administering to the subject a composition comprising a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof wherein a therapeutically effective amount of a compound reduces cyclic adenosine monophosphate levels, and wherein the formula of the compound is selected from the group consisting of:
and any combination thereof wherein,
R is an optionally substituted cyclic or bicyclic ring structure; wherein R is selected from the group consisting of phenyl, pyranyl, pyridyl, imidazolyl, 1,8-naphthridinyl and N-oxide pyridyl
X is an alkyl, oxygen, an ester, an amine, or an amide
Z is selected from the group consisting of hydrogen, alkenyl, alkynyl, phenyl, benzyl, halo, fluoro, chloro, bromo, iodo, hydroxy, keto, oxo, aldo, carbonate, carboxy, alkoxy, ester, carboxamido, amino, ammonio, imino, imido, azido, azo, cyanato, isocyano, isocyanato, isothiocyanato, nitroxy, cyano, nitrosooxy, nitro, nitroso, 4-pyridyl, 3-pyridyl, 2-pyridyl, thioether, sulfonyl, sulfo, sulfinyl, mercapto, sulfanyl, sulfhydryl, sulfonamino, thiocyanato, alkyl amino, hydroxyamic acid, methyl, ethyl, 1,3-dioxylanyl, propyl, iso-propyl, butyl, tert-butyl, alkyl, (C1-C3) alkenyl, aryl, alkylaryl;
W is selected from the group consisting of CO, NH, methylene, sulfur atom, oxygen atom and thionyl; and,
n is 0 or 1 wherein the intestinal fluid loss is the result of a bacterial infection of a pathogen, wherein the pathogen is selected from a group consisting of B. antracis, V. cholerae, E. coli, S. typhimurium, Y. pestis and any combination thereof.
2. The method of claim 1 , wherein R is mono, di, tri, tetra, or appropriately penta substituted with a functional group selected form the group consisting of alkenyl, alkynyl, phenyl, benzyl, halo, fluoro, chloro, bromo, iodo, hydroxy, keto, oxo, aldo, carbonate, carboxy, alkoxy, ester, carboxamido, amino, ammonio, imino, imido, azido, azo, cyanato, isocyano, isocyanato, isothiocyanato, nitroxy, cyano, nitrosooxy, nitro, nitroso, 4-pyridyl, 3-pyridyl, 2-pyridyl, thioether, sulfonyl, sulfo, sulfinyl, mercapto, sulfanyl, sulfhydryl, sulfonamino, thiocyanato, alkyl amino, hydroxyamic acid, methyl, ethyl, 1,3-dioxylanyl, propyl, iso-propyl, butyl, tert-butyl, alkyl, (C1-C3) alkenyl, aryl, alkylaryl, and any combination thereof.
3. The method of claim 1 , wherein the compound is from the group consisting of
and any combination thereof.
4. The method of claim 1 , wherein the method comprises inhibiting adenylyl cyclase, edema factor, CTA1, or any combination thereof.
5. The method of claim 1 , wherein the intestinal fluid loss is caused by an increase in 3′,5′-adenosine monophosphate levels in the subject's tissue.
6. The method of claim 1 , wherein the composition is administered in combination with one or more other drugs.
7. The method of claim 1 , wherein the composition further comprises an antibiotic or an anti-inflammatory.
8. The method of claim 1 , wherein the composition comprises a pharmaceutically acceptable carrier.
9. The method of claim 1 , wherein the compound is delivered at dosages between 0.001 mM and 10 mM.
10. The method of claim 9 , wherein the compound is delivered at dosages between 0.1 mM and 1 mM.
11. The method of claim 1 , wherein the subject is a human.
12. The method of claim 1 , wherein the composition is administered through a route selected from the group consisting of alimentary, parenteral, topical, mucosal, inhalation and any combination thereof.
