Sakamoto, Kentarou;Michibata, Junya;Hirai, Yusuke;Ide, Akiko;Ikitoh, Asuka;Takatani-Nakase, Tomoka;Futaki, Shiroh research published 《 Potentiating the Membrane Interaction of an Attenuated Cationic Amphiphilic Lytic Peptide for Intracellular Protein Delivery by Anchoring with Pyrene Moiety》, the research content is summarized as follows. We previously reported an approach for intracellular protein delivery by attenuating membrane-lytic activity of cationic amphiphilic peptides on cell surfaces. HAad is one such peptides that cytosolically delivers proteins of interest, including antibodies, by stimulating their endosomal escape. Addnl., HAad elicits ruffling of cell membrane, accompanied by transient membrane permeabilization, allowing for the efficient cytosolic translocation of proteins. In this study, we prepared a conjugate of HAad with pyrenebutyric acid as a membrane-anchoring unit (pBu-HAad). pBu-HAad demonstrated protein delivery into cells with only 1/20 concentration of HAad. However, the conjugates with cholesteryl hemisuccinate and aliphatic fatty acids (C = 3, 6, and 10) did not yield such marked effects. The results of time-course and inhibitor studies suggest that the membrane anchoring of HAad by a pyrene moiety leads to enhanced peptide-membrane interaction and to loosen lipid packing, thus facilitating cytosolic translocation through membranes.

Ryckaert, Bram;Hullaert, Jan;Van Hecke, Kristof;Winne, Johan M. research published 《 Dearomative (3 + 2) Cycloadditions of Unprotected Indoles》, the research content is summarized as follows. The (3 + 2) cycloaddition of various indoles I [R = H, Me, Br, CN, etc.; R₁ = H, Me; RR₁ = -(CH₂)₄-, -(CH₂)₃-] with dithioallyl cation affords dearomatized cyclopentannulated adducts e.g. II, with complete control of regioselectivity and excellent chemo- and diastereoselectivity. The success of the reaction critically relies on the use of an excess of very strong Bronsted acid, which paradoxically prevents carbocationic side reactions. The reaction tolerates sensitive functionalities such as basic amines or free hydroxyls, and its use in late stage derivatization of highly functionalized, unprotected indoles was demonstrated.

Ruel, David M.;Vainer, Yuri;Yakir, Esther;Bohbot, Jonathan D. research published 《 Identification and functional characterization of olfactory indolergic receptors in Drosophila melanogaster》, the research content is summarized as follows. Indole-sensitive odorant receptors or indolORs belong to a mosquito-specific expansion as ancient as the Culicidae lineage. Brachyceran flies appeared to lack representative members of this group despite the importance of indolics in this important group of dipterans. To explore whether indolORs occur in other brachyceran species, we searched for candidate indolORs in Drosophila melanogaster. Using phylogenetic tools, we show that D. melanogaster OR30a, OR43a, and OR49b form a distinct monophyletic lineage with mosquito indolORs. To explore a potential functional orthol. with indolORs, we expressed these three Drosophila ORs in Xenopus laevis oocytes and measured their responses to a panel of indolic compounds We provide evidence that OR30a, OR43a, and OR49b exhibit high sensitivity to indoles. Along with the recent discovery of indolORs in the housefly Musca domestica, our findings suggest that indolORs are a widespread feature of the peripheral olfactory systems of Diptera.

Ronchi, Elisabetta;Paradine, Shauna M.;Jacobsen, Eric N. research published 《 Enantioselective, Catalytic Multicomponent Synthesis of Homoallylic Amines Enabled by Hydrogen-Bonding and Dispersive Interactions》, the research content is summarized as follows. A one-step catalytic, enantioselective method for the preparation of homoallylic N-Boc amines (R)-RCH(NHBoc)CH(R¹)C(R²)=CH₂ (R = Ph, cyclohex-1-en-1-yl, 2H-1,3-benzodioxol-5-yl, etc.; R¹ = H, Me; R² = Me, Ph, 2-phenylethenyl) directly from acetals RCH(OMe)₂ was reported. Reactive iminium ion intermediates are generated in situ through the combination of an acetal, a chiral thiourea catalyst, trialkylsilyl triflate, and N-Boc carbamate and are subsequently trapped by a variety of allylsilane nucleophiles R¹CH=C(R²)CH₂Si(CH₃)₂. No homoallylic ether byproducts are detected, consistent with allylation of the iminium intermediate being highly favored over allylation of the intermediate oxocarbenium ion. Acetals derived from aromatic aldehydes RCHO possessing a variety of functional groups and substitution patterns yield homoallylic amines with excellent levels of enantiomeric enrichment. Exptl. and computational data are consistent with an anchoring hydrogen-bond interaction between the protioiminium ion and the amide of the catalyst in the enantiodetermining transition state, and with stereodifferentiation achieved through specific noncovalent interactions (NCIs) with the catalyst pyrenyl moiety. Evidence is provided that the key NCI in the major pathway is a π-stacking interaction, contrasting with the cation-π interactions invoked in previously studied reactions promoted by the same family of aryl-pyrrolidino-H-bond-donor catalysts.

Ulcerative colitis and Crohn′s disease are forms of inflammatory bowel disease whose incidence and prevalence are increasing worldwide. These diseases lead to chronic inflammation of the gastrointestinal tract as a result of an abnormal response of the immune system. Recent studies positioned Cortistatin, which shows low stability in plasma, as a candidate for IBD treatment. Here, using NMR structural information, we design five Cortistatin analogs adopting selected native Cortistatin conformations in solution One of them, A5, preserves the anti-inflammatory and immunomodulatory activities of Cortistatin in vitro and in mouse models of the disease. Addnl., A5 displays an increased half-life in serum and a unique receptor binding profile, thereby overcoming the limitations of the native Cortistatin as a therapeutic agent. This study provides an efficient approach to the rational design of Cortistatin analogs and opens up new possibilities for the treatment of patients that fail to respond to other therapies.

Rao, Muhammad Junaid;Duan, Mingzheng;Wei, Xiaoshuang;Zuo, Hou;Ma, Li;Tahir ul Qamar, Muhammad;Li, Min;Han, Shijian;Hu, Lihua;Wang, Lingqiang research published 《 LC-MS / MS -based metabolomics approach revealed novel phytocompounds from sugarcane rind with promising pharmacological value》, the research content is summarized as follows. Sugarcane provides many secondary metabolites for the pharmacol. and cosmetic industries. Secondary metabolites, such as phenolic compounds, flavonoids, and anthocyanins, have been studied, but few reports focus on the identification of alkaloid and non-alkaloid phytocompounds in sugarcane. In this study, we identified 40 compounds in total from the rinds of cultivated sugarcane varieties (including eight alkaloids, 24 non-alkaloids, and eight others) by using the liquid chromatog.-tandem mass spectrometry (LC-MS/MS) approach. Among these compounds, 31 were novel and are reported for the first time in sugarcane. Some alkaloids such as 3-indoleacrylic acid, N,N-dimethyl-5-methoxytryptamine, tryptamine, 6-hydroxynicotinic acid, and 6-deoxyfagomine are identified the first time in sugarcane rind. Four alkaloids such as trigonelline, piperidine, 3-indoleacrylic acid, and 6-deoxyfagomine are found abundantly in sugarcane rind and these compounds have promising pharmaceutical value. Some phytocompounds such as choline and acetylcholine (non-alkaloid compounds) were most common in the rind of ROC22 and Yuetang93/159 (YT93/159). Hierarchical cluster anal. and principal component anal. revealed that the ROC22, Taitang172 (F172), and Yuetang71/210 (YT71/210) varieties were quite similar in alkaloid composition when compared with other sugarcane varieties. We have also characterized the biosynthesis pathway of sugarcane alkaloids. The rind of F172, ROC22, and YT71/210 showed the highest total alkaloid content, whereas the rind of ROC16 revealed a min. level. Interestingly, the rind extract from YT71/210 and F172 showed maximum antioxidant activity, followed by ROC22. Our results showed the diversity of alkaloid and non-alkaloid compounds in the rind of six cultivated sugarcanes and highlighted the promising phytocompounds that can be extracted, isolated, and utilized by the pharmacol. industry. 2022 Society of Chem.

A novel strategy for the synthesis of 3-hydroxycarbazoles involving the consecutive propargylation/palladium-catalyzed hydroxylative benzannulation of indole-2-carbonyls with propargylic alcs. has been exploited. This one-pot procedure leads to a wide range of substituted 3-hydroxycarbazoles in high yield with a broad substrate scope. The method was further extended to access furano-carbazole derivatives from dialkynols via tandem annulations.
