New Indole Tubulin Assembly Inhibitors Cause Stable Arrest of Mitotic Progression, Enhanced Stimulation of Natural Killer Cell Cytotoxic Activity, and Repression of Hedgehog-Dependent Cancer

We designed 39 new 2-phenylindole derivatives as potential anticancer agents bearing the 3,4,5-trimethoxyphenyl moiety with a sulfur, ketone, or methylene bridging group at position 3 of the indole and with halogen or methoxy substituent(s) at positions 4-7. Compounds 33 and 44 strongly inhibited the growth of the P-glycoprotein-overexpressing multi-drug-resistant cell lines NCI/ADR-RES and Messa/Dx5. At 10 nM, 33 and 44 stimulated the cytotoxic activity of NK cells. At 20-50 nM, 33 and 44 arrested >80% of HeLa cells in the G2/M phase of the cell cycle, with stable arrest of mitotic progression. Cell cycle arrest was followed by cell death. Indoles 33, 44, and 81 showed strong inhibition of the SAG-induced Hedgehog signaling activation in NIH3T3 Shh-Light II cells with IC50 values of 19, 72, and 38 nM, respectively.

Exploration of quinoxaline derivatives as antimicrobial and anticancer agents

Novel 2 and 3-substituted quinoxaline derivatives were synthesized through various synthetic pathways, among which cyanoacetamide and cyanoacetohydrazide quinoxaline derivatives 4a-c and 11a-c, respectively, were synthesized. Furthermore, methoxy quinoxaline derivatives 3c and quinoxaline derivatives bearing substituted pyridines 6a,b, 12a,b, and 13a,b were designed to be synthesized. However, we have synthesized acrylohydrazide 5a,b and 7/acrylamide derivatives, Schiff base analogues 14a-f, pyrazole derivatives 15a-e, amide derivatives 16a-f, guanidine derivatives 16 g,h as well as, quinoxalin-2-methylallyl propionate derivative 14g. All the synthesized compounds were confirmed via spectral data and elemental analyses. Moreover, the newly synthesized compounds were evaluated for their antimicrobial activity (Gm +ve, Gm ?ve in comparison to Gentamycin a standard) and fungi (in comparison to Ketoconazole as a standard). Thus, compound 16b showed promising antimicrobial activity against B. subtilis, P. vulgaris, and S. mutants with values ranging from 20 to 27-mm zone of inhibition. While compounds 5a, 14e,f, and 16a,c,d,g,h showed potent antimicrobial activity. Moreover, the National Cancer Institute (NCI) selected 20 compounds that were submitted for anticancer screening against 60 types of cancer cell lines. The most active compounds are 5b and 12a where compound 5b containing 2,4-dichlorophenyl moiety at cyanoacetamide linkage of hydrazine quinoxaline backbone exerted significant growth inhibition activity against Leukemia MOLT-4, Renal cancer UO-31, and Breast cancer MCF-7. In addition, compound 12a having 4,6-diaminopyridinone side chain at position-3 of quinoxaline nucleus exhibited remarkable anticancer activity against renal cancer UO-31.

Antimicrobial evaluation and action mechanism of chalcone derivatives containing quinoxaline moiety

Abstract: A series of chalcone derivatives containing quinoxaline moieties were synthesized, and their antibacterial activities were evaluated. Antibacterial bioassays indicated that some of the compounds exhibited significant antibacterial activity against Xanthomonas axonopodis pv. Citri (Xac), Xanthomonas oryzae pv. oryzae (Xoo), and Ralstonia solanacearum (Rs) at the concentrations of 50 or 100 mug/cm3. 50% effective concentration (EC50) values of (E)-3-(pyridin-2-yl)-1-[4-(quinoxalin-2-yloxy)phenyl]prop-2-en-1-one against Xac, Xoo, and Rs were 6.72, 15.17, and 9.29 mug/cm3, respectively, which were better than those of bismerthiazol (44.31, 42.46, and 62.36 mug/cm3, respectively). Scanning electron microscopy (SEM) was employed to analyze the mechanism of antibacterial action of that compound toward Xac. Graphical abstract: [Figure not available: see fulltext.].

Iodobenzene-catalyzed oxidative C[sbnd]H d3-alkoxylation of quinoxalinones with deuterated alcohols

A convenient and practical iodobenzene-catalyzed synthesis of trideuteroalkoxylated quinoxalinones has been developed under transition-metal-free conditions. The present transformation can be accomplished through C[sbnd]H/O[sbnd]H cross-dehydrogenative-coupling of quinoxalinones with deuterated alcohol. Various substrates are compatible, providing the corresponding products in moderate to good yields. A free radical pathway mechanism is advised for the transformation.

Visible-light-driven cyanoalkylation of quinoxalinones using cyclobutanone oxime esters as the radical precursors

We have developed a versatile visible-light-driven cyanoalkylation of quinoxalinones under mild conditions. First, the cyanoalkyl radicals are generated from readily available cyclobutanone oxime esters under blue light irradiation. Then the generated radicals react with heterocycles such as quinoxalinones to give the final cyanoalkylation products. The protocol tolerates a wide range of functional groups. Our cyanoalkylation protocol does not need cyanide-based reagents and also does not need external oxidants.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 55687-34-8, help many people in the next few years.Computed Properties of C8H5BrN2O
