A potent, small molecule inhibitor with a favorable pharmacokinetic profile to allow for sustained SCD inhibition in vivo was identified. Starting from a low MW acyl guanidine (5a), identified with a RapidFire High-Throughput Mass Spectrometry (RF-MS) assay, iterative library design was used to rapidly probe the amide and tail regions of the molecule. Singleton synthesis was used to probe core changes. Biological evaluation of a SCD inhibitor (5b) included in vitro potency at SCD-1 and in vivo modulation of the plasma desaturation index (DI) in rats on a low essential fatty acid (LEFA) diet. In addition to dose-dependent decrease in DI, effects on rodent ocular tissue were noted. Therefore, in rat, these SCD inhibitors only recapitulate a portion of phenotype exhibited by the SCD-1 knockout mouse.

A series of novel bicyclic 1-heteroaryl-4-[omega-(1H-indol-3-yl)alkyl] piperazines was synthesized and evaluated on binding to dopamine D2 receptors and serotonin reuptake sites. This class of compounds proved to be potent in vitro dopamine D2 receptor antagonists and in addition were highly active as serotonin reuptake inhibitors. Some key representatives showed potent pharmacological in vivo activities after oral dosing in both the antagonism of apomorphine-induced climbing and the potentiation of 5-HTP-induced behavior in mice. On the basis of the preclinical data, 8-{4-[3-(5-fluoro-1H- indol-3-yl)propyl]piperazin-1-yl}-4H-benzo[1,4]oxazin-(R)-2-methyl-3-one (45c, SLV314) was selected for clinical development. In vitro and in vivo studies revealed that 45c has favorable pharmacokinetic properties and a high CNS plasma ratio. Molecular modeling studies showed that the bifunctional activity of 45c can be explained by its ability to adopt two different conformations fitting either the dopamine D2 receptor pharmacophore or the serotonin transporter pharmacophore.

A highly regioselective and stereoselective cascade annulation of indoles with C2-symmetric enone tethered-cyclohexadienones provides rapid access to complex indole alkaloid-like scaffolds in high yields. Interestingly, a different reaction course was observed with 3-substituted indoles giving C-2/N annulation products with similar complexity via intramolecular aza-Michael addition. This desymmetrization approach is highly practical and allows atom-economical synthesis of natural product-like molecules containing several contiguous stereocenters with broad range of substrate scope and high functional-group tolerance. The synthetic utility of the products was demonstrated with various chemoselective, regioselective, and diastereoselective transformations on the highly strained polycyclic indoles to elaborate the value of this tandem reaction.

Recently, we discovered 3-aminomethylquinoline derivative 1, a selective, highly potent, centrally acting, and orally bioavailable human MCH receptor 1 (hMCHR1) antagonist, that inhibited food intake in F344 rats with diet-induced obesity (DIO). Subsequent investigation of 1 was discontinued because 1 showed potent hERG K+ channel inhibition in a patch-clamp study. To decrease hERG K+ channel inhibition, experiments with ligand-based drug designs based on 1 and a docking study were conducted. Replacement of the terminal p-fluorophenyl group with a cyclopropylmethoxy group, methyl group introduction on the benzylic carbon at the 3-position of the quinoline core, and employment of a [2-(acetylamino)ethyl]amino group as the amine portion eliminated hERG K+ channel inhibitory activity in a patch-clamp study, leading to the discovery of N-{3-[(1R)-1-{[2-(acetylamino)ethyl]amino} ethyl]-8-methylquinolin-7-yl}-4-(cyclopropylmethoxy)benzamide (R)-10h. The compound (R)-10h showed potent inhibitory activity against hMCHR1 and dose-dependently suppressed food intake in a 2-day study on DIO-F344 rats. Furthermore, practical chiral synthesis of (R)-10h was performed to determine the molecule’s absolute configuration.

Photochemical oxidative cyclodehydrogenation reactions are a versatile class of aromatic ring-forming reactions. They are tolerant to functional group substitution and heteroatom inclusion, so can be used to form a diverse range of extended polyaromatic systems by fusing existing ring substituents. However, despite their undoubted synthetic utility, there are no existing models?computational or heuristic?that predict the outcome of photocyclisation reactions across all possible classes of reactants. This can be traced back to the fact that ?negative? results are rarely published in the synthetic literature and the lack of a general conceptual framework for understanding how photoexcitation affects reactivity. In this work, we address both of these issues. We present experimental data for a series of aromatically substituted pyrroles and indoles, and show that quantifying induced atomic forces upon photoexcitation provides a powerful predictive model for determining whether a given reactant will photoplanarise and hence proceed to photocyclised product under appropriate reaction conditions. The propensity of a molecule to photoplanarise is related to localised changes in charge distribution around the putative forming ring upon photoexcitation. This is promoted by asymmetry in molecular structures and/or charge distributions, inclusion of heteroatoms and ethylene bridging and well-separated or isolated photocyclisation sites.

Methods to reversibly control the chemical environment of hydrogels have application in three-dimensional cell culture to study cell proliferation, migration and differentiation in environments more representative of in vivo environments. Herein, we have developed a method to temporally control the chemical environment of agarose hydrogels through non-covalent attachment of peptide motifs. Streptavidin-GRGDS conjugates were immobilized in desthiobiotin-modified agarose hydrogels through the desthiobiotin-streptavidin interaction (KD 10-11 M). Streptavidin-GRGDS was then displaced from the gel by the addition of biotin, which has a higher affinity for streptavidin (KD 10-15 M). This process was repeated to sequentially and simultaneously immobilize different biomolecules and model compounds in hydrogels over the course of several hours to weeks. The influence of dynamic chemical environments on cellular activity was demonstrated by monitoring HUVEC tube formation for 30 h.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 473257-60-2, you can also check out more blogs about473257-60-2

An unprecedented Rh-catalyzed C2-difluoroalkylation of indole derivatives with 2,2-difluorovinyl arenesulfonates has been reported. This reaction provides a rare instance of catalytic difluoroalkylation through hydroarylation of gem-difluoroalkenes. The sulfonate group works as a chelating ligand, thus stabilizing the rhodacycle intermediate, leading to the uncommon transformation.
