A series of cinnolines/quinolines was prepared and it was found that 4-phenyl-cinnoline/quinolines with either a 2′,3′ or 2′,5′-disubstituted benzyloxy moiety or the 1-Me-7-indole methoxy moiety on the meta position of the 4-Ph ring showed good binding selectivity for LXRβ over LXRα. The LXRβ binding selective modulators displayed good activity for inducing ABCA1 gene expression in J774 macrophage cell line and poor efficacy in the LXRα Gal4 functional assay. 26, 37 and 41 were examined for their ability to induce SREBP-1c gene expression in Huh-7 liver cell line and they were weak partial agonists.

Pytlarczyk, Marta published the artcileNematic stability of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls and its deuterated isotopologue, Safety of 4-Chloro-2-fluoroiodobenzene, the main research area is alkylphenyl boronic acid chlorotrifluoro biphenyl palladium SPhos catalyst coupling; trifluoro alkyl terphenyl preparation.

In this work, three synthetic methodologies of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls were presented. The most convenient synthetic method was used for homologous series of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls (alkyl chain from Me to hexyl). The results showed that fluorination in the inner-core position (at 2 and 2′ position of terphenyl core) promoted only a nematic phase. The results was discussed with other chloro- and fluoro- substituted 4”-alkyl-[1,1′:4′,1”]terphenyls and one perdeuterated terphenyl analog. The synthesis and purity of synthesized compounds were monitored by gas chromatog. GC-MS, GC-FID and by thin layer chromatog. (TLC). The phase situation and the phase transition temperatures were determined by polarized optical microscopy (POM). The temperatures and enthalpies of the phase transitions were measured by using differential scanning calorimetry (DSC).

Elkamhawy, Ahmed published the artcileThiazolidine-2,4-dione-based irreversible allosteric IKK-β kinase inhibitors: Optimization into in vivo active anti-inflammatory agents, Name: 4-(4-Chlorophenoxy)benzaldehyde, the main research area is IKK beta modulators signaling pathway allosteric modulation antiinflammatory; Allosteric modulation; Anti-inflammatory; IKK-β modulators; NF-κB signaling pathway; Thiazolidine-2,4-diones.

Selective kinase inhibitors development is a cumbersome task because of ATP binding sites similarities across kinases. On contrast, irreversible allosteric covalent inhibition offers opportunity to develop novel selective kinase inhibitors. Previously, we reported thiazolidine-2,4-dione lead compounds eliciting in vitro irreversible allosteric inhibition of IKK-β. Herein, we address optimization into in vivo active anti-inflammatory agents. We successfully developed potent IKK-β inhibitors with the most potent compound eliciting IC50 = 0.20μM. Cellular assay of a set of active compounds using bacterial endotoxin lipopolysaccharide (LPS)-stimulated macrophages elucidated significant in vitro anti-inflammatory activity. In vitro evaluation of microsomal and plasma stabilities showed that the promising compound 7a is more stable than compound 7p. Finally, in vivo evaluation of 7a, which has been conducted in a model of LPS-induced septic shock in mice, showed its ability to protect mice against septic shock induced mortality. Accordingly, this study presents compound 7a as a novel potential irreversible allosteric covalent inhibitor of IKK-β with verified in vitro and in vivo anti-inflammatory activity.

Kersten, Philip published the artcileEnzymic release of halogens or methanol from some substituted protocatechuic acids, Synthetic Route of 62936-23-6, the main research area is protocatechuate metabolism bacteria halogen methanol.

Four strains of gram-neg. bacteria capable of growing at the expense of 5-chlorovanillate were isolated from soil, and the metabolism of 1 strain was studied in particular detail. In the presence of α,α’-bipyridyl, a suspension of 5-chlorovanillate-grown cells accumulated 5-chloroprotocatechuate from 5-chlorovanillate; in the absence of inhibitor these compounds, and various other 5-substituted protocatechuates and vanillates, were oxidized to completion. Cell suspensions of this strain grown on 5-chlorovanillate or vanillate released Cl- quant. from 5-chlorovanillate and released MeOH from syringate. Extracts of cells grown with 4-hydroxybenzoate, vanillate, or syringate possessed high levels of both protocatechuate 4,5-dioxygenase and 2-pyrone-4,6-dicarboxylate hydrolase; extracts from acetate-grown cells did not. Protocatechuate 4,5-dioxygenase, purified from strains that could grow with 5-chlorovanillate, oxidized 5-halogeno-protocatechuates and 3-O-methylgallate with the formation of 2-pyrone-4,6-dicarboxylate. A crude extract converted 5-chloroprotocatechuate into pyruvate plus oxaloacetate. A meta-fission reaction sequence is proposed for the bacterial degradation of vanillate and protocatechuate substituted at C-5 of the benzene ring with halogen or methoxyl.
