The present invention disclosed compounds of Structural Formula (I), and enantiomer, racemic body, pharmaceutically acceptable salts, solvates or hydrates thereof, wherein variable groups are as defined within, as well as methods for preparing such compounds. The compounds are useful as PPARγ agonist, through activating PPAR-RXR heterodimers that interacts with specific DNA response elements within promoter regions of target gene, particularly in the treatment and prevention of polycystic kidney and cancer.

Lonidamine derivatives can be useful in methods of treating, inhibiting, and / or preventing polycystic kidney disease (PKD). Accordingly, lonidamine derivatives can be administered in a therapeutically effective amount for inhibiting, and / or preventing polycystic kidney disease (PKD) in the subject. This can include administering a therapeutically effective amount of the lonidamine derivatives for inhibiting CFTR and / or Hsp90 or biological pathway thereof. Also, the method can include administering the lonidamine derivatives in a therapeutically effective amount for inhibiting ErbB2, Src, Raf-1, B-Raf, MEK, Cdk4, NKCC1, or combinations thereof. For example, the therapeutically effective amount of the lonidamine derivatives can be configured so as to provide a concentration in or adjacent to a kidney cell of about 0.25 uM or more or less.

The present invention provides a method for treating, inhibiting the progression of, or eradicating polycystic kidney disease of in a patient in need thereof which comprises providing to said patient an effective amount of a TACE inhibitor compound alone or in combination with an effective amount of an EGF receptor kinase inhibitor.

An object of the present invention is to provide a combination drug that has remarkably excellent preventive and / or therapeutic effects on polycystic kidney disease. The present invention provides a drug for preventing and / or treating polycystic kidney disease comprising a combination of tolvaptan or a prodrug thereof with a somatostatin derivative, and a method for treating polycystic kidney disease using this drug.

The invention discloses a novel Chinese medicinal composition for treating renal cyst diseases and a preparation method thereof. The Chinese medicinal composition mainly comprises the following raw material medicaments: mix-fried pangolin scales, tangerine peel, Chinese angelica, immature bitter orange, common burreed rhizome, zedoary, turmeric root-tuber, peach seed, safflower, turtle shell, tortoise plastron, Szechuan lovage rhizome, red paeony root, dragon's blood, Chinese eaglewood, green tangerine peel, root of red-rooted salvia, Indian buead, oriental waterplantain rhizome, cortex lyciiradicis, amur corktree bark, gardenia, Vietnamese sophora root, raw rehmannia root, liriope, coridius, nutgrass galingale rhizome, medicated leaven and plantain seed. The Chinese medicinal composition can be prepared into any common oral preparation by the conventional Chinese medicinal preparation method. The Chinese medicinal composition can obviously improve symptoms such as renal cyst, polycystic kidney, extensive abdominal edema, uroclepsia, hematuria, albuminuria, urinary tract infection, malaise, loss of appetite, dreaminess, insomnia, amnesia and the like. The Chinese medicinal composition has the advantages of exact clinical effects, obvious curative effect, quick response, low cost, basically no toxic or side effects and the like because the Chinese medicinal composition basically combines medicaments having homology of medicament and food specified in national formulary.

In order to determine the epigenetic mutation of autosomal dominant polycystic kidney disease and its functional relevance, the present inventors randomly analyzed the whole genome of polycystic kidney disease and non-polycystic kidney disease individuals by methylation profiling method and compared with their performance data. Interestingly, PKD1 and other genes associated with ion transport and cell binding were hypermethylated at the gene body, which was downregulated in polycystic kidney disease. In particular, PKD1 is partially hypermethylated in the polycystic kidney gene body, which is associated with MBD2 (methyl‑CpG‑binding domain 2) protein binding. Furthermore, DNA methylation inhibitor treatment was accompanied by an upregulation of PKD1 expression and delayed cyst formation in MDCK (Madin‑Darby Canine Kidney) cells. Thus, hypermethylation of PKD1 and cyst formation-associated regulatory genes of the present invention is decisive for cyst formation and revealed to be useful as a treatment for autosomal dominant polycystic kidney disease.

The present invention provides compositions and methods for detecting mutations associated with polycystic kidney disease in the cat.

Methods for treating autosomal dominant polycystic kidney disease (ADPKD) are described herein. More particularly, methods described herein relate generally to administering glutaminase1 inhibitors to subjects afflicted with ADPKD. Accordingly, the use and application of compounds or agents that inhibit glutaminase1 for treating ADPKD or for use in a medicament for treating ADPKD are encompassed herein.
