Structure-activity relationship studies of lipophilic teicoplanin pseudoaglycon derivatives as new anti-influenza virus agents. Eur J Med Chem 2018; 157:1017-1030. [PMID: 30170320 PMCID: PMC7115582 DOI: 10.1016/j.ejmech.2018.08.058] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2018] [Revised: 08/20/2018] [Accepted: 08/21/2018] [Indexed: 02/03/2023]
Abstract
Six series of semisynthetic lipophilic glycopeptide antibiotic derivatives were evaluated for in vitro activity against influenza A and B viruses. The new teicoplanin pseudoaglycon-derived lipoglycopeptides were prepared by coupling one or two side chains to the N-terminus of the glycopeptide core, using various conjugation methods. Three series of derivatives bearing two lipophilic groups were synthesized by attaching bis-alkylthio maleimides directly or through linkers of different lengths to the glycopeptide. Access to the fourth and fifth series of compounds was achieved by click chemistry, introducing single alkyl/aryl chains directly or through a tetraethylene glycol linker to the same position. A sixth group of semisynthetic derivatives was obtained by sulfonylation of the N-terminus. Of the 42 lipophilic teicoplanin pseudoaglycon derivatives tested, about half showed broad activity against influenza A and B viruses, with some of them having reasonable or no cytotoxicity. Minor differences in the side chain length as well as lipophilicity appeared to have significant impact on antiviral activity and cytotoxicity. Several lipoglycopeptides were also found to be active against human coronavirus. Multiple series of lipophilic teicoplanin pseudoaglycon derivatives were prepared. Alkyl or aryl chains were coupled to the N-terminus by various conjugation methods. The activity of new antibiotic derivatives was evaluated against influenza viruses. Half of the 42 derivatives showed high activity against influenza A and B viruses. The length and lipophilicity of the side chains influence the antiviral activity.

Abstract
The Mitsunobu reaction basically consists in the conversion of an alcohol into an ester under inversion of configuration, employing a carboxylic acid and a pair of two auxiliary reagents, mostly triphenylphosphine and a dialkyl azodicarboxylate. This reaction has been frequently used in carbohydrate chemistry for the modification of sugar hydroxy groups. Modification at the anomeric position, leading mainly to anomeric esters or glycosides, is of particular importance in the glycosciences. Therefore, this review focuses on the use of the Mitsunobu reaction for modifications of sugar hemiacetals. Strikingly, unprotected sugars can often be converted regioselectively at the anomeric center, whereas in other cases, the other hydroxy groups in reducing sugars have to be protected to achieve good results in the Mitsunobu procedure. We have reviewed on the one hand the literature on anomeric esterification, including glycosyl phosphates, and on the other hand glycoside synthesis, including S- and N-glycosides. The mechanistic details of the Mitsunobu reaction are discussed as well as this is important to explain and predict the stereoselectivity of anomeric modifications under Mitsunobu conditions. Though the Mitsunobu reaction is often not the first choice for the anomeric modification of carbohydrates, this review shows the high value of the reaction in many different circumstances.

HS-116, a novel phosphatidylinositol 3-kinase inhibitor induces apoptosis and suppresses angiogenesis of hepatocellular carcinoma through inhibition of the PI3K/AKT/mTOR pathway. Cancer Lett 2011; 316:187-95.

Abstract
The phosphatidylinositol 3-kinase (PI3K) pathway plays a central role in cell proliferation and survival of human cancers. As PI3K is active in many cancer patients, resulting in cancer development and progression, we developed an azaindole derivative, HS-116 as a novel PI3K inhibitor. This study aimed to clarify the anticancer effect of HS-116 in human hepatocellular carcinoma (HCC). To identify the effect of HS-116 on HCC cells, a PI3K assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometry, and Western blotting were conducted. IC(50) of HS-116 for PI3Kα was 31nM, and it effectively suppressed the phosphorylation of PI3K downstream factors such as AKT, mTOR, p70S6K, and 4EBP1. Also, HS-116 induced apoptosis by increasing the proportion of sub-G1 apoptotic cells from 1.8% to 35% and increasing the expressions of Bax, cleaved-caspase-3, and cleaved-PARP as well as decreasing the expression of Bcl-2. In addition, chromatin condensation and apoptotic bodies were detected in HS-116-treated HCC cells. Furthermore, HS-116 decreased protein expression of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF), and inhibited the tube formation and migration of human umbilical vein endothelial cells (HUVECs). In vivo, the ability of mice to vascularize subcutaneously implanted Matrigel plugs was diminished when the mice were treated with HS-116. These results show that HS-116 inhibits the PI3K/AKT/mTOR pathway via apoptosis and anti-angiogenesis in HCC cells. We suggest that HS-116 may be an effective novel therapeutic candidate against HCC.

Abstract
Rebeccamycin is an indolocarbazole class inhibitor of topoisomerase I. In the course of structure-activity relationship studies on rebeccamycin derivatives, we have synthesized analogs with the sugar moiety attached to either one or both indole nitrogens. Some analogs, especially those with substitutions at the 6' position of the carbohydrate moiety, exhibit potent inhibitory activity toward checkpoint kinase 1 (Chk1), a kinase that has a major role in the G(2)/M checkpoint in response to DNA damage. Some of these compounds retained a genotoxic activity either through intercalation into the DNA and/or by topoisomerase I-mediated DNA cleavage. We explored the structure-activity relationship between these compounds and their multiple targets. These rebeccamycin derivatives represent a novel class of potential antitumor agents that have a dual effect and might selectively induce the death of cancer cells.

Abstract
We here report the synthesis and biological evaluation of new phenylcarbazole derivatives designed as potential anticancer agents. Indole and hydroxyindole were used to generate three scaffolds that were successively exploited to introduce various substituents on the maleimide moiety. The synthesis includes a final intramolecular key Heck-type reaction, which was carried out with a triflate derivative or with a bromophenyl derivative. Each step was optimized and the complete chemical strategy is detailed. Several compounds showed a marked cytotoxicity against CEM human leukemia cells with IC(50) values in the 10-100 nM range. Precise structure-activity relationships were delineated. Cell cycle analysis, topoisomerase I inhibition, and interaction with DNA were evaluated, and inhibition of CDK activity was also investigated. Although binding of the drugs to DNA likely contributes to the cytotoxic action, the exact molecular targets of these molecules remain undiscovered. The efficient chemical routes reported here for the design of highly cytotoxic compounds provide novel opportunities to identify antitumor agents in the phenylcarbazole series.

Abstract
We report the efficient synthesis involving palladium-catalyzed reactions and biological evaluation of new naphthocarbazoles designed as potential anticancer agents. The use of 5- and 6-benzyloxyindoles generated three substitution sites which were successively exploited to introduce several hydrophilic side chains. The cytotoxicity of the newly designed compounds was evaluated on three cell lines. Several compounds showed a marked cytotoxicity with IC(50) values in the sub-micromolar range. This is the case for the 3-hydroxy-naphthopyrrolocarbazoledione 37, bearing a dimethylaminoethyl side chain, which is extremely cytotoxic to L1210 and DU145 cells (IC(50): 36 nM, 108 nM) and induces an accumulation of L1210 cells in the G2+M phases of the cell cycle. Some of the most cytotoxic compounds were tested for inhibition of CDK-5, GSK-3 and topoisomerase I, and their interaction with DNA was also evaluated. Interaction with DNA was detected, suggesting that nucleic acids represent a privileged target for these molecules.

Abstract
[reaction: see text] Compounds containing a pyridine nucleus fused to a saturated nitrogen-containing ring, including 7-azaoxindoles, 7-azaindolines, tetrahydro[1,8]naphthyridines, and tetrahydro-5H-pyrido[2,3-b]azepin-8-ones, were prepared in good yield starting from various 2,6-dichloropyridines. The method hinges on a free-radical xanthate-mediated cyclization or intermolecular addition/cyclization sequence for the construction of the new fused rings.

Abstract
In the course of structure-activity relationship studies, new rebeccamycin derivatives substituted in 3,9-positions on the indolocarbazole framework, and a 2',3'-anhydro derivative were prepared by semi-synthesis from rebeccamycin. The antiproliferative activities against nine tumor cell lines were determined and the effect on the cell cycle of murine leukemia L1210 cells was examined. Their DNA binding properties and inhibitory properties toward topoisomerase I and three kinases PKCzeta, CDK1/cyclin B, CDK5/p25 and a phosphatase cdc25A were evaluated. The 3,9-dihydroxy derivative is the most efficient compound of this series toward CDK1/cyclin B and CDK5/p25. It is also characterized as a DNA binding topoisomerase I poison. Its broad spectrum of molecular activities likely accounts for its cytotoxic potential. This compound which displays a tumor cell line-selectivity may represent a new lead for subsequent drug design in this series of glycosylated indolocarbazoles.

Abstract
Rebeccamycin, a microbial metabolite possessing a maleimide indolo[2,3-a]carbazole framework with a carbohydrate moiety attached to one of the indole nitrogens, is a well-known topoisomerase I inhibitor. This review reports the various total syntheses of rebeccamycin and structure-activity relationship studies on rebeccamycin analogues. Rebeccamycin analogues were prepared either by semi-synthesis from the natural metabolite or by total synthesis. Different families of rebeccamycin analogues were obtained by modifications at the imide heterocycle, dechlorination and substitutions on the indole moieties, modifications of the sugar residue, construction of dimers, coupling the sugar unit to the second indole nitrogen, changing indolo[2,3-a]carbazole skeleton to indolo[2,3-c]carbazole, replacing one or both indole moieties by 7-azaindole units. The biological activities of the rebeccamycin analogues are described. According to their chemical structure, the analogues can inhibit topoisomerase I and/or kinases. From the structure-activity relationships, some important rules were established. Several compounds exhibit stronger antiproliferative activities than the natural metabolite with IC(50) values in the nanomolar range. Some analogues, especially those possessing azaindole moieties, are much more selective than rebeccamycin toward the tumour cell lines tested.
