Discovery of 4-Methylquinazoline Based PI3K Inhibitors for the Potential Treatment of Idiopathic Pulmonary Fibrosis

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease, and its molecular pathogenesis remains poorly understood. Recently, emerging evidence demonstrates that the PI3K signaling transduction pathway is linked to the pathology of IPF. In this work, we rationally designed a new series of 4-methylquinazoline derivatives as highly potent PI3K inhibitors that significantly suppress the phosphorylation of the main PI3K downstream effectors and displays marked antiproliferative activity in mouse MLg2908 lung fibroblasts. In a bleomycin-induced mouse pulmonary fibrosis model, 5d from the series improved mouse lung function and slowed the progression of pulmonary fibrosis. Overall, this work promises a therapeutic potential for PI3K inhibitors to treat IPF.

Stereochemical Studies on Porphyrin a: Assignment of the Absolute Configuration of a Model Porphyrin by Degradation

The synthesis is described of a porphyrin alcohol (22) which has a structure very similar to that of porphyrin a (2).The model porphyrin was resolved by separation of its camphanate esters.Ozonolysis of the 2-nitrobenzoate of each enantiomer in tritiated form gave a derivative of 2-hydroxypentadioic acid whose configuration was determined by dilution analysis.It is demonstrated that correlation of the stereochemistry of porphyrin a with that of the model (22) will be possible by means of the (1)H and (19)F n.m.r. spectra of the corresponding esters with (-)-3,3,3-trifluoro-2-methoxy-2-phenylpropanoic acid.

Synthesis of 2-(phenylselanyl)tetrahydrofurans from gamma-lactones and of gamma-hydroxydiselenoacetals from gamma-lactols

A known one-pot procedure for the synthesis of 2-(phenylselanyl)tetrahydrofurans could be applied to the transformation of gamma-lactones 3a-c into 2-(phenylselanyl)tetrahydrofurans 1a-c. Surprisingly, formation of gamma-hydroxydiselenoacetals 5b and 5c was observed when gamma-lactols 4b and 4c were treated with selenophenol and boron trifluoride etherate.

Design and optimization of selective azaindole amide M1 positive allosteric modulators

Selective activation of the M1 receptor via a positive allosteric modulator (PAM) is a new approach for the treatment of the cognitive impairments associated with schizophrenia and Alzheimer’s disease. A novel series of azaindole amides and their key pharmacophore elements are described. The nitrogen of the azaindole core is a key design element as it forms an intramolecular hydrogen bond with the amide N-H thus reinforcing the bioactive conformation predicted by published SAR and our homology model. Representative compound 25 is a potent and selective M1 PAM that has well aligned physicochemical properties, adequate brain penetration and pharmacokinetic (PK) properties, and is active in vivo. These favorable properties indicate that this series possesses suitable qualities for further development and studies.

Anionic surfactants based on intermediates of carbohydrate conversion

Starting from the bio-based platform chemicals 5-hydroxymethylfurfural (HMF) and furfural, a library of anionic surfactants was synthesized using stoichiometric and catalytic reactions. In total, seven different surfactants with varying chain lengths were prepared and tested for industrially relevant properties, such as critical micelle concentration (CMC) and interfacial tension towards isopropyl myristate. Surfactants based on 2,5-bis(hydroxymethyl)-tetrahydrofuran (BHMTHF), which are accessible via acid-catalysis over zeolites, were identified as the most promising candidates for possible industrial applications. Variants with chain lengths of C12-C14 showed the best results in terms of physico-chemical properties. These lengths represent the usually occurring length of carbon chains in natural oils, opening up a pathway for a possible production of the here used substrates. The other synthesized surfactants, accessible via stoichiometric routes, also showed promising results in terms of CMC and interfacial tension.

Multiclass method for pesticides quantification in honey by means of modified QuEChERS and UHPLC-MS/MS

Bee products can be produced in an environment contaminated by pesticides that can be transported by honey bees to the hive and incorporated into the honey. Therefore, rapid and modern methods to determine pesticide residues in honey samples are essential to guarantee consumers’ health. In this study, a simple multiresidue method for the quantification of 116 pesticides in honey is proposed. It involves the use of a modified QuEChERS procedure followed by UHPLC-MS/MS analysis. The method was validated according to the European Union SANCO/12571/2013 guidelines. Acceptable values were obtained for the following parameters: linearity, limit of detection (0.005 mg/kg) and limit of quantification (0.010 and 0.025 mg/kg), trueness (for the four tested levels the recovery assays values were between 70 and 120%), intermediate precision (RSD < 20.0%) and measurement uncertainty tests (<50.0%). The validated method was applied for determination of 100 honey samples from five states of Brazil. One of the oldest and most widely used commercial enzyme inhibitors is aspirin, name: Furan-2,4(3H,5H)-dione, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 4971-56-6

Application of olefin metathesis to the synthesis of ABE ring analogues of methyllycaconitine

The synthesis of four novel ABE ring analogues of methyllycaconitine (MLA) is reported, employing olefin metathesis as the key step for appending the seven-membered B ring onto an AE bicyclic ring system. This strategy allows the stereodivergent synthesis of ABE ring analogues in which the stereochemistry of the AB ring junction is well defined. The compounds are designed as ligands to study binding and function of the alpha7-nAChR.
