Design and synthesis of quinolinones as methionyl-tRNA synthetase inhibitors

Five new structural analogues of substituted-1H-quinolinones (19, 20, 23, 24, and 26) have been synthesized and evaluated for Staphylococcus aureus methionyl-tRNA synthetase enzyme inhibitory activity. These compounds were also tested against pathogens of six S. aureus, two Enterococcus faecalis, and one Enterococcus faecium. Among all the synthesized quinolinones, compound 20 displayed significant inhibitory activities in the strains of E. faecalis and E. faecium.

Organocatalytic, diastereo- and enantioselective synthesis of nonsymmetric cis -stilbene diamines: A platform for the preparation of single-enantiomer cis -imidazolines for protein-protein inhibition

The finding by scientists at Hoffmann-La Roche that cis-imidazolines could disrupt the protein-protein interaction between p53 and MDM2, thereby inducing apoptosis in cancer cells, raised considerable interest in this scaffold over the past decade. Initial routes to these small molecules (i.e., Nutlin-3) provided only the racemic form, with enantiomers being enriched by chromatographic separation using high-pressure liquid chromatography (HPLC) and a chiral stationary phase. Reported here is the first application of an enantioselective aza-Henry approach to nonsymmetric cis-stilbene diamines and cis-imidazolines. Two novel mono(amidine) organocatalysts (MAM) were discovered to provide high levels of enantioselection (>95% ee) across a broad range of substrate combinations. Furthermore, the versatility of the aza-Henry strategy for preparing nonsymmetric cis-imidazolines is illustrated by a comparison of the roles of aryl nitromethane and aryl aldimine in the key step, which revealed unique substrate electronic effects providing direction for aza-Henry substrate-catalyst matching. This method was used to prepare highly substituted cis-4,5-diaryl imidazolines that project unique aromatic rings, and these were evaluated for MDM2-p53 inhibition in a fluorescence polarization assay. The diversification of access to cis-stilbene diamine-derived imidazolines provided by this platform should streamline their further development as chemical tools for disrupting protein-protein interactions.

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.Application of 1055361-35-7, you can also check out more blogs about1055361-35-7

Desulfurilative self-coupling reaction of 1,3-thiazolidine-2-thiones and intramolecular non-bonded S?S interaction in the crystallographic structure of the products

An attempt at an asymmetric Pummerer-type reaction of trans-4-benzyloxythiane-1-oxide (1) with 3-trifluoroacetyl-4S-isopropyl-1,3-thiazolidine-2-thione (2) resulted in failure but an attractive desulfurilative self-coupling reaction of 4S-isopropyl-1,3-thiazolidine-2-thione (6) occurred to give 4S-isopropyl-3-(4S-isopropyl-1,3-thiazolin-2-yl)-1,3-thiazolidine-2-thione (5). The same desulfurilative self-coupling reaction of compound 6 or 11 efficiently proceeded by treatment of diphenyl sulfoxide (7a) or methyl phenyl sulfoxide (7b) with 2 or 3-trifluoroacetyl-1,3-thiazolidine-2-thione (8) to afford each corresponding product 5 or 9. Eventually, we found a practically useful method for the synthesis of 5 and 9 by exploiting TiCl4 and sodium salt 12 or 13 of 1,3-thiazolidine-2-thiones. Interestingly, intramolecular non-bonded S?S interactions were recognized in the crystallographic structures of 5 and 9.

Biased signaling and allosteric modulation at the FSHR

Knowledge on G protein-coupled receptor (GPCRs) structure and mechanism of activation has profoundly evolved over the past years. The way drugs targeting this family of receptors are discovered and used has also changed. Ligands appear to bind a growing number of GPCRs in a competitive or allosteric manner to elicit balanced signaling or biased signaling (i.e., differential efficacy in activating or inhibiting selective signaling pathway(s) compared to the reference ligand). These novel concepts and developments transform our understanding of the follicle-stimulating hormone (FSH) receptor (FSHR) biology and the way it could be pharmacologically modulated in the future. The FSHR is expressed in somatic cells of the gonads and plays a major role in reproduction. When compared to classical GPCRs, the FSHR exhibits intrinsic peculiarities, such as a very large NH2-terminal extracellular domain that binds a naturally heterogeneous, large heterodimeric glycoprotein, namely FSH. Once activated, the FSHR couples to Galphas and, in some instances, to other Galpha subunits. G protein-coupled receptor kinases and beta-arrestins are also recruited to this receptor and account for its desensitization, trafficking, and intracellular signaling. Different classes of pharmacological tools capable of biasing FSHR signaling have been reported and open promising prospects both in basic research and for therapeutic applications. Here we provide an updated review of the most salient peculiarities of FSHR signaling and its selective modulation.

Substituted phenyl sulfonamides as selective beta 3 agonists for the treatment of diabetes and obesity

Substituted phenylsulfonamides are selective beta 3 adrenergic receptor agonists with very little beta 1 and beta 2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have potent activity in the treatment of Type II diabetes and obesity. The compounds can also be used to lower triglyceride levels and cholesterol levels or raise high density lipoprotein levels or to decrease gut motility. In addition, the compounds can be used to reduced neurogenic inflammation or as antidepressant agents. The compounds are prepared by coupling an aminoalkylphenyl-sulfonamide with an appropriately substituted alkyl epoxide. Compositions and methods for the use of the compounds in the treatment of diabetes and obesity and for lowering triglyceride levels and cholesterol levels or raising high density lipoprotein levels or for increasing gut motility are also disclosed.

Novel tetrazoloquinoline-rhodanine conjugates: Highly efficient synthesis and biological evaluation

In search of new active molecules against Mycobacterium tuberculosis (MTB) H37Ra and Mycobacterium bovis BCG, a small focused library of rhodanine incorporated tetrazoloquinoline has been efficiently synthesized by using [HDBU][HSO4] acidic ionic liquid. The compound 3c found to be promising inhibitor of MTB H37Ra and M. bovis BCG characterized by lower MIC values 4.5 and 2.0 mug/mL, respectively. The active compounds were further tested for cytotoxicity against HeLa, THP-1, A549 and PANC-1 cell lines using MTT assay and showed no significant cytotoxic activity at the maximum concentration evaluated. Again, the synthesized compounds were found to have potential antifungal activity. Furthermore, to rationalize the observed biological activity data, the molecular docking study also been carried out against a potential target Zmp1 enzyme of MTB H37Ra, which revealed a significant correlation between the binding score and biological activity for these compounds. The results of in vitro and in silico study suggest that these compounds possess ideal structural requirement for the further development of novel therapeutic agents.
