Design, synthesis and pharmacology of 1,1-bistrifluoromethylcarbinol derivatives as liver X receptor beta-selective agonists

A novel series of 1,3-bistrifluoromethylcarbinol derivatives that act as liver X receptor (LXR) beta-selective agonists was discovered. Structure-activity relationship studies led to the identification of molecule 62, which was more effective (Emax) and selective toward LXRbeta than T0901317 and GW3965. Furthermore, 62 decreased LDL-C without elevating the plasma TG level and significantly suppressed the lipid-accumulation area in the aortic arch in a Bio F1B hamster fed a diet high in fat and cholesterol. We demonstrated that our LXRbeta agonist would be potentially useful as a hypolipidemic and anti-atherosclerotic agent. In this manuscript, we report the design, synthesis and pharmacology of 1,3-bistrifluoromethylcarbinol derivatives.

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 2879-20-1, help many people in the next few years.2879-20-1

Ruthenium Complexes Immobilized on Functionalized Knitted Hypercrosslinked Polymers as Efficient and Recyclable Catalysts for Organic Transformations

A hypercrosslinked polymer (HCP)-immobilized ruthenium catalyst (HCP?PPh3?Ru) was prepared from benzene and triphenylphosphine (PPh3) through a one-step external cross-linking reaction. The structure and composition of the catalyst were fully characterized by many physicochemical methods. HCP?PPh3?Ru was found to possess high Brunauer?Emmett?Teller (BET) surface area, large pore volume, and low skeletal density. Moreover, the Ru catalyst was also featured some advantages, such as low synthetic cost and good chemical and thermal stability. HCP?PPh3?Ru was then used as a recoverable and effective catalyst for the synthesis of 2,4-diaryl-substituted pyridines from acetophenones, ammonium acetate (NH4OAc) and dimethylformamide (DMF), and the cycloaddition reaction of diazodicarbonyl compounds with olefins to afford dihydrofurans. In addition, a combination of HCP?PPh3?Ru and Amberlyst-15 enabled us to establish a simple protocol for the direct synthesis of carbazole derivatives from diazodicarbonyl compound, alkyl vinyl ether and indole. In these selected reactions, the catalyst was easily recovered and reused several times without significant activity loss. (Figure presented.).

Synthesis and cytotoxic activities of a series of novel N -methyl-bisindolylmaleimide amide derivatives

A novel series of N-methyl-bisindolylmaleimides were synthesized and evaluated for their inhibitory activities against nine tumor cell lines. Some of the compounds showed an interesting activity against the tested cell lines. The most potent compounds 5e and 5j displayed antiproliferative activity with 50% inhibitory concentration values in the muM range against some tested cell lines.

Exploring the Existing Drug Space for Novel pTyr Mimetic and SHP2 Inhibitors

Protein tyrosine phosphatases (PTPs) are potential therapeutic targets for many diseases. Unfortunately, despite considerable drug discovery efforts devoted to PTPs, obtaining selective and cell permeable PTP inhibitors remains highly challenging. We describe a strategy to explore the existing drug space for previously unknown PTP inhibitory activities. This led to the discovery of cefsulodin as an inhibitor of SHP2, an oncogenic phosphatase in the PTP family. Crystal structure analysis of SHP2 interaction with cefsulodin identified sulfophenyl acetic amide (SPAA) as a novel phosphotyrosine (pTyr) mimetic. A structure-guided and SPAA fragment-based focused library approach produced several potent and selective SHP2 inhibitors. Notably, these inhibitors blocked SHP2-mediated signaling events and proliferation in several cancer cell lines. Thus, SPAA may serve as a new platform for developing chemical probes for other PTPs.

1,2-Benzothiazine 1,1-dioxide P2-P3 peptide mimetic aldehyde calpain I inhibitors

A series of peptide mimetic aldehyde inhibitors of calpain I was prepared in which the P2 and P3 amino acids were replaced by substituted 3,4-dihydro-1,2-benzothiazine-3-carboxylate 1,1-dioxides. The effect of 2, 6, and 7-benzothiazine substituents and the P1 amino acid was examined. Potency of these inhibitors, 15c-p, against human recombinant calpain I is particularly dependent upon the 2-substituent, with methyl and ethyl generally more potent than hydrogen, isopropyl, isobutyl, or benzyl. The more potent diastereomer of 15m possesses the (S) absolute configuration at the 3-position of the 3,4-dihydro-l,2-benzothiazine. Potency of the best inhibitors in this series (IC50=5-7 nM) compares favorably with that of conventional N-benzyloxycarbonyl dipeptide aldehyde inhibitors bearing L-Leu or L-Val residues at P2. The achiral unsaturated 1,2-benzothiazine analogues 26a-d are also potent calpain I inhibitors, while 3,4-dihydro-2,1-benzoxathiin (15a,b), 1,2,4-benzothiadiazine (32a,b), and tetrahydroisoquinolinone (36a,b) analogues are less potent.
