BACKGROUND OF THE INVENTION SUMMARY OF THE INVENTION 0002 The invention provides compositions including 0007. The present invention provides compositions that compounds having an inhibitory effect on Sodium-dependent include compounds having an inhibitory effect on Sodium glucose cotransporter SGLT. The invention also provides dependent glucose cotransporter SGLT. The invention also pharmaceutical compositions and methods of using the com provides pharmaceutical compositions and methods of using pounds, independently or in combination with other thera the compounds, independently or in combination with other peutic agents, for treating diseases and conditions that are therapeutic agents, for treating diseases and conditions which affected by SGLT inhibition. are affected by SGLT inhibition such as: type 1 diabetes 0003. According to the World Health Organization, mellitus, type 2 diabetes mellitus, hyperglycemia, diabetic approximately 150 million people worldwide have diabetes complications, insulin resistance, metabolic syndrome (Syn mellitus. The two principal forms of diabetes are type 1 dia drome X), hyperinsulinemia, hypertension, hyperuricemia, betes, in which the pancreas fails to produce insulin, and type obesity, edema, dyslipidemia, chronic heart failure, and ath 2 diabetes, in which the body fails to respond properly to the erosclerosis. insulin produced (insulin resistance). Accounting for about 0008. In one aspect, the invention features compounds 90% of all diabetes cases, type 2 diabetes is by far the most having the structure: common. In both types of diabetes, the absence of insulin action or proper response to insulin results in elevated levels of serum glucose (hyperglycemia). Serious complications (I) associated with diabetes include retinopathy (leading to visual impairment or blindness), cardiovascular disease, nephropathy, neuropathy, ulcers, and diabetic foot disease. 0004 Individuals with type 1 diabetes currently require insulin therapy. While in many cases type 2 diabetes can be managed with diet and exercise, drug intervention is also frequently required. Besides insulin, which is needed by about one-third of patients with type 2 diabetes, current antidiabetic therapies include biguanides (which decrease glucose production in the liver and increase sensitivity to insulin), Sulfonylureas and meglitinides (which stimulate insulin production), alpha-glucosidase inhibitors (which or any stereoisomer or tautomer thereof, or any pharmaceu slow starch absorption and glucose production), and thiazo tically acceptable prodrug, salt, or Solvate thereof, wherein lidinediones (which increase insulin sensitivity).

Such side effects include lactic acidosis (bigu anides), hypoglycemia (Sulfonylureas), and edema and weight gain (thiazolidinediones). (Q) 0005 One promising target for therapeutic intervention in diabetes and related disorders is the glucose transport system of the kidneys. Cellular glucose transport is conducted by either facilitative (“passive) glucose transporters (GLUTs) or Sodium-dependent ("active) glucose cotransporters (SGLTs). SGLT1 is found predominantly in the intestinal brush border, while SGLT2 is localized in the renal proximal Ril R2 10 tubule and is reportedly responsible for the majority of glu cose reuptake by the kidneys.

  • Selective Production of Phase-Separable Product from a Mixture of Biomass-Derived Aqueous Oxygenates
    ARTICLE DOI: 10.1038/s41467-018-07593-0 OPEN Selective production of phase-separable product from a mixture of biomass-derived aqueous oxygenates Yehong Wang 1, Mi Peng2, Jian Zhang1, Zhixin Zhang1, Jinghua An1,3, Shuyan Du1, Hongyu An1,3, Fengtao Fan1, Xi Liu 4,5, Peng Zhai2, Ding Ma 2 & Feng Wang1 1234567890():,; Selective conversion of an aqueous solution of mixed oxygenates produced by biomass fermentation to a value-added single product is pivotal for commercially viable biomass utilization. However, the efficiency and selectivity of the transformation remains a great challenge. Herein, we present a strategy capable of transforming ~70% of carbon in an aqueous fermentation mixture (ABE: acetone–butanol–ethanol–water) to 4-heptanone (4- HPO), catalyzed by tin-doped ceria (Sn-ceria), with a selectivity as high as 86%. Water (up to 27 wt%), detrimental to the reported catalysts for ABE conversion, was beneficial for producing 4-HPO, highlighting the feasibility of the current reaction system. In a 300 h continuous reaction over 2 wt% Sn-ceria catalyst, the average 4-HPO selectivity is main- tained at 85% with 50% conversion and > 90% carbon balance. This strategy offers a route for highly efficient organic-carbon utilization, which can potentially integrate biological and chemical catalysis platforms for the robust and highly selective production of value-added chemicals. 1 State Key Laboratory of Catalysis, Dalian National Laboratory for Clean Energy, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian 116023, China. 2 College of Chemistry and Molecular Engineering and College of Engineering, BIC-ESAT, Peking University, Beijing 100871, China.

Endothelin is synthesized in vascular endothelial and smooth muscle cells, as well as in neural, renal, pulmonic, and inflammatory cells. It acts through a seven transmembrane endothelin receptor A (ETA) and endothelin receptor B (ETB) receptors belongs to G protein-coupled rhodopsin-type receptor superfamily. This peptide involved in pathogenesis of cardiovascular disorder like (heart failure, arterial hypertension, myocardial infraction and atherosclerosis), renal failure, pulmonary arterial hypertension and it also involved in pathogenesis of cancer. Potentially endothelin receptor antagonist helps the treatment of the above disorder. Currently, there are a lot of trails both per-clinical and clinical on endothelin antagonist for various cardiovascular, pulmonary and cancer disorder. Some are approved by FAD for the treatment. These agents are including both selective and non-selective endothelin receptor antagonist (ETA/B). Currently, Bosentan, Ambrisentan, and Macitentan approved

    CENTER FOR DRUG EVALUATION AND RESEARCH APPLICATION NUMBER: 204569Orig1s000 MEDICAL REVIEW(S) Cross Discipline Team Leader Review 3. CMC/Device Dr. Khairuzzaman found the drug product portion of the NDA to be acceptable, and without need for phase 4 commitments. Dr. Sapru’s review stated that with the exception of a pending issue concerning the control of potential genotoxic impurity (b) (4) the NDA was approvable in terms of drug substance. Dr. Suarez found that the NDA was acceptable from a biopharmaceutics perspective. The Office of Compliance issuance of an acceptable recommendation for drug substance manufacturing and testing facilities was pending at the time of this review. 4. Nonclinical Pharmacology/Toxicology Dr. Richard Siarey completed the primary nonclinical review, and Dr. Lois Freed completed a supervisory memo. Dr. Siarey’s overall conclusion was that from a nonclinical perspective, approval of the suvorexant NDA was recommended. However, he found evidence that catapelxy was observed in dogs exposed to MK-4305 (suvorexant) near Tmax, although he concluded that additional information could have been gained by studying the drug in an experimental model that has been used for diagnosing cataplexy in dogs. Dr. Siarey suggested that since cataplexy occurred in dogs near Tmax, a time at which if used for insomnia patients would ordinarily be in bed, safety concern for humans was reduced. Dr. Siarey also found that the neurobehavioral assessment in the pre- and post-natal developmental study was not complete, as the passive avoidance tests was performed too early in development, while learning/acquisition tests and retention/memory tests were not conducted.
