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.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2144-40-3, help many people in the next few years.HPLC of Formula: C6H12O3

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.

Free-wilson and structural approaches to Co-optimizing human and rodent isoform potency for 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) inhibitors

11beta-Hydroxysteroid dehydrogenase 1 (11beta-HSD1) has been a target of intensive research efforts across the pharmaceutical industry, due to its potential for the treatment of type II diabetes and other elements of the metabolic syndrome. To demonstrate the value of 11beta-HSD1 in preclinical models, we required inhibitors with good potency against both human and rodent isoforms. Herein, we describe our efforts to understand how to co-optimize human and murine potency within the (5-hydroxy-2-adamantyl)-pyrimidine-5-carboxamide series. Two approaches are described-a data-driven (Free-Wilson) analysis and a structure-based design approach. The conclusions from these approaches were used to inform an efficient campaign to design compounds with consistently good human/murine potency within a logD7.4 range of 1-3. Compounds 20 and 26 demonstrated good rodent PK, which allowed us to demonstrate a PK/PD relationship in rat and mouse. We then evaluated 26 against glycemic and body weight end points in murine disease models, where it demonstrated glucose and body weight efficacy at 300 mg/kg/day but only body weight efficacy at 50 mg/kg/day, despite providing >90% target engagement in the liver.

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.

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.
