- Construction of Oxepino[3,2-b]indoles via [4+3] Annulation of 2-Ylideneoxindoles with Crotonate-Derived Sulfur Ylides
-
A [4+3] annulation of 2-ylideneoxindoles with crotonate-derived sulfur ylides has been developed. A series of oxepino[3,2-b]indoles were prepared in moderate to excellent yields (62-93%) under mild conditions. Moreover, the synthetic oxepino[3,2-b] indoles can be further transformed into more complex cyclopropa[5,6]oxepino[3,2-b]indoles via a [2+1] cyclopropanation. In addition, the synthetic compounds show certain antiproliferative activity against K562 and MCF-7 cells, and its IC50 values for these two kinds of tumor cells up to 5.40±0.88 μM and 18.41±0.50 μM, respectively. (Figure presented.).

- Synthesis, antimicrobial and cytotoxic activities, and molecular docking studies of N-arylsulfonylindoles containing an aminoguanidine, a semicarbazide, and a thiosemicarbazide moiety
-
Thirty-six N-arylsulfonyl-3-substituted indoles were designed and synthesized by combining the N-arylsulfonylindoles with aminoguanidine, semicarbazide, and thiosemicarbazide, respectively. Their antibacterial activities were screened, and cytotoxic activities were evaluated. The results showed that aminoguanidines (6) exhibited much better antibacterial activity than semicarbazides (7) and thiosemicarbazides (8). Most compounds in series 6 showed potent inhibitory activity against the tested bacterial strains, including multidrug-resistant strains, with MIC values in the range of 1.08–23.46 μM. The cytotoxic activity of the compounds 6c, 6d, 6h, 6j, 6k and 6l was assessed in two human cancer cell lines A590 and SGC7901, and one human normal cell line HEK 293T. The results indicated that compounds selected exhibited excellent activity against the tested cancer cells with IC50 values in the range of 1.51–15.12 μM suggesting the potential of them as new antibacterial and anticancer agents. What's more, the results of resistance study revealed that resistance of the tested bacteria toward 6d is not easily developed. Molecular docking studies revealed that the aminoguanidine and arylsulfonylindole moieties played a significant role in binding the target site of E. coli FabH-CoA receptor.

- Development of indole sulfonamides as cannabinoid receptor negative allosteric modulators
-
Existing CB1 negative allosteric modulators (NAMs) fall into a limited range of structural classes. In spite of the theoretical potential of CB1 NAMs, published in vivo studies have generally not been able to demonstrate the expected therapeutically-relevant CB1-mediated effects. Thus, a greater range of molecular tools are required to allow definitive elucidation of the effects of CB1 allosteric modulation. In this study, we show a novel series of indole sulfonamides. Compounds 5e and 6c (ABD1075) had potencies of 4 and 3?nM respectively, and showed good oral exposure and CNS penetration, making them highly versatile tools for investigating the therapeutic potential of allosteric modulation of the cannabinoid system.

- Synthesis and antitumor activity of new thiazole nortopsentin analogs
-
New thiazole nortopsentin analogs in which one of the two indole units was replaced by a naphthyl and/or 7-azaindolyl portion, were conveniently synthesized. Among these, three derivatives showed good antiproliferative activity, in particular against MCF7 cell line, with GI50 values in the micromolar range. Their cytotoxic effect on MCF7 cells was further investigated in order to elucidate their mode of action. Results showed that the three compounds act as pro-apoptotic agents inducing a clear shift of viable cells towards early apoptosis, while not exerting necrotic effects. They also caused cell cycle perturbation with significant decrease in the percentage of cells in the G0/G1 and S phases, accompanied by a concomitant percentage increase of cells in the G2/M phase, and appearance of a subG1-cell population.

- Exploration of a series of 5-arylidene-2-thioxoimidazolidin-4-ones as inhibitors of the cytolytic protein perforin
-
A series of novel 5-arylidene-2-thioxoimidazolidin-4-ones were investigated as inhibitors of the lymphocyte-expressed pore-forming protein perforin. Structure-activity relationships were explored through variation of an isoindolinone or 3,4-dihydroisoquinolinone subunit on a fixed 2-thioxoimidazolidin-4-one/thiophene core. The ability of the resulting compounds to inhibit the lytic activity of both isolated perforin protein and perforin delivered in situ by natural killer cells was determined. A number of compounds showed excellent activity at concentrations that were nontoxic to the killer cells, and several were a significant improvement on previous classes of inhibitors, being substantially more potent and soluble. Representative examples showed rapid and reversible binding to immobilized mouse perforin at low concentrations (≤2.5 μM) by surface plasmon resonance and prevented formation of perforin pores in target cells despite effective target cell engagement, as determined by calcium influx studies. Mouse PK studies of two analogues showed T1/2 values of 1.1-1.2 h (dose of 5 mg/kg iv) and MTDs of 60-80 mg/kg (ip).

- Novel bis(1H-indol-2-yl)methanones as potent inhibitors of FLT3 and platelet-derived growth factor receptor tyrosine kinase
-
FLT3 receptor tyrosine kinase is aberrantly active in many cases of acute myeloid leukemia (AML). Recently, bis(1H-indol-2-yl)methanones were found to inhibit FLT3 and PDGFR kinases. To optimize FLT3 activity and selectivity, 35 novel derivatives were synthesized and tested for inhibition of FLT3 and PDGFR autophosphorylation. The most potent FLT3 inhibitors 98 and 102 show IC 50 values of 0.06 and 0.04 μM, respectively, and 1 order of magnitude lower PDGFR inhibiting activity. The derivatives 76 and 82 are 20- to 40-fold PDGFR selective. Docking at the recent FLT3 structure suggests a bidentate binding mode with the backbone of Cys-694. Activity and selectivity can be related to interactions of one indole moiety with a Hydrophobic pocket including Phe-691, the only different binding site residue (PDGFR Thr-681). Compound 102 inhibited the proliferation of 32D cells expressing wildtype FLT3 or FLT3-ITD similarly as FLT3 autophosphorylation, and induced apoptosis in primary AML patient blasts.
