MODULATORS OF G-PROTEIN COUPLED RECEPTORS

This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt and/or hydrate and/or prodrug of the compound) that modulate (e.g., agonize or partially agonize or antagonize) glucagon?like peptide?1 receptor (“GLP?1R”) and/or the gastric inhibitory polypeptide receptor (“GIPR”). The chemical entities are useful, e.g., for treating a subject (e.g., a human) having a disease, disorder, or condition in which modulation (e.g., agonism, partial agonism or antagonism) of GLP?1R and/or GIPR activities is benficial for the treatment or prevention of the underlying pathology and/or symptoms and/or progression of the disease, disorder, or condition. In some embodiments, the modulation results in an enhancment of (e.g., an increase in) existing levels (e.g., normal or below normal levels) of GLP?1R and/or GIPR activity (e.g., signaling). In some embodiments, the chemical entities described herein further modulate (e.g., attenuate, uncouple) -arrestin signaling relative to what is observed with the native ligand. This disclosure also features compositions as well as other methods of using and making the said chemical entities.

An interrupted fischer indolization approach toward fused indoline-containing natural products

An efficient method to access the fused indoline ring system present in a multitude of bioactive molecules has been developed. The strategy involves the condensation of hydrazines with latent aldehydes to ultimately deliver indoline-containing products by way of an interrupted Fischer indolization sequence. Our studies show that the approach will likely be amenable to the synthesis of complex targets, such as the communesin natural products.

Eosin Y- and Copper-Catalyzed Dark Reaction to Construct Ene-gamma-Lactams

Eosin Y, a common organo-photocatalyst in visible-light photoredox processes, was found to show excellent catalytic activities for thermal redox reactions under a catalytic amount of Cu(OAc)2. With this catalytic system, vinyl azides and ketene silyl acetals combine to form formal [3 + 2] cycloadducts by alpha-ester radical addition without light irradiation. This method provides a mild and straightforward paradigm to prepare important synthons of five-membered ene-gamma-lactams and bridge ring lactams. It is the first example of an eosin Y-catalyzed redox reaction in the dark.

B(C6F5)3-Catalyzed Silation of Alcohols: A Mild, General Method for Synthesis of Silyl Ethers

The commercially available borane tris(pentafluorophenyl)borane, B(C6F5)3, is an effective catalyst for the dehydrogenative silation of alcohols using a variety of silanes, R3SiH, R2SiH2, and R2R?SiH. Generally, the reactions occur in a convenient time frame at room temperature using 2 mol % of the borane and are clean and high yielding, with dihydrogen as the only byproduct. Primary aliphatic alcohols are silated cleanly but slowly, with reaction times ranging from 20 to 144 h. Faster reaction times can be achieved by increasing the catalyst loading to 8 mol % or by heating the reaction to ?60C. Secondary and tertiary alcohols react more rapidly, with most reactions being complete in 0.5-2 h. The reaction is tolerant of many functional groups including C=C, C=C, -Br, aliphatic ketones, C(O)OR, lactones, furans, OBn, OMe, and NO2; examples of each are given. Using the phenolic substrate 2,4,6-trimethylphenol, a number of different silanes were tested. Only the most bulky silanes (Bn3SiH and Pri3SiH) were not reactive under these conditions. The selectivity of the silation reactions are roughly governed by the relative basicity of the alcohols (and other functions in the molecule) with more basic groups being selectively silated. These observations are rationalized on the basis of a mechanism that invokes borane activation of the silane by hydride abstraction. The resulting intermediate silylium/hydridoborate ion pair then reacts with alcohols to give the observed silyl ether and dihydrogen products.

Pyrolysis of alpha-cellulose using a multimode microwave oven

alpha-Cellulose was pyrolyzed using a multimode microwave oven, different microwave absorbers and experimental set ups. The microwave absorber showed a strong influence: carbon gave a large gasification of cellulose (yield of gas up to 53.8%) while Al2O3 gave a high yield of bio-char (64.1%) and a low gas production (3.0%). Bio-oil was obtained with the highest yield (37.6%) using iron as microwave absorber and a condenser between the oven and the collecting system. Dark brown bio-oils having low density and viscosity due to the presence of large amount of furanosidic compounds were collected. Bio-oils were characterized through GC?MS, FT-IR, NMR, The GC?MS analysis was employed to evaluate the composition of bio-oils using calculated retention factors. A high concentration of levoglucosan (133.9 mg/mL) together with acetic acid, acetic anhydride, 1-hydroxy-2-propanone, formic acid and furfural were obtained using graphite as microwave absorber. A mechanisms was proposed to rationalize the formation of aromatic compounds present in bio-oils. Water contents in bio-oils were affected by all parameters of the process, mainly by the microwave absorber. The use of silica has proved to be a promising way to obtain bio-oil with low water content (13%), while pyrolysis in the presence of carbon gave a large amount of water (46%).
