1,2,4-trisubstituted pyrrolo[1,2-a]quinoxalines are synthesized through the multi-component reaction of 3-substituted 2-chloroquinoxalines, propargyl bromide, and excess secondary amines in the presence of a palladium copper catalytic system. This one-pot process provides an unexpected synthesis of new trisubstituted pyrrolo[1,2-a]quinoxalines by the introduction of two amine substituents onto the fused pyrrole rings in a single reaction procedure. The compounds formed are fully characterized by the analytical spectral data and X-ray analysis. A number of synthesized pyrrolo[1,2-a]quinoxaline derivatives are also screened against the three bacterial strains Micrococcus luteus, Pseudomonas aeruginos, and Bacillus subtilis. According to the results obtained, compounds 3b, 3c, and 3e are active against M. luteus, compounds 3b and 3e are active against Ps. Aeruginos, and only compound 3f is active against all the three bacterial strains.

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.

Choline kinase alpha (ChoKalpha) is an enzyme involved in the synthesis of phospholipids and thereby plays key roles in regulation of cell proliferation, oncogenic transformation, and human carcinogenesis. Since several inhibitors of ChoKalpha display antiproliferative activity in both cellular and animal models, this novel oncogene has recently gained interest as a promising small molecule target for cancer therapy. Here we summarize our efforts to further validate ChoKalpha as an oncogenic target and explore the activity of novel small molecule inhibitors of ChoKalpha. Starting from weakly binding fragments, we describe a structure based lead discovery approach, which resulted in novel highly potent inhibitors of ChoKalpha. In cancer cell lines, our lead compounds exhibit a dose-dependent decrease of phosphocholine, inhibition of cell growth, and induction of apoptosis at low micromolar concentrations. The druglike lead series presented here is optimizable for improvements in cellular potency, drug target residence time, and pharmacokinetic parameters. These inhibitors may be utilized not only to further validate ChoKalpha as antioncogenic target but also as novel chemical matter that may lead to antitumor agents that specifically interfere with cancer cell metabolism.

Systems have been prepared composed of aromatic groups rigidly arranged to form ? 15 by ?20 A rectangular surfaces containing two regularly spaced protruding methyls at 3 and 9 o’clock and two methyl-sized holes at 12 and 6 o’clock (e.g., 1). These molecules form dimers with large common surfaces in which the four methyl groups insert into the four holes. The resulting complexes have 82 to 132 intermolecular atom-to-atom contacts at van der Waals distances +0.2 A (five crystal structures). Substitution of ethyls or hydrogens for the central aryl methyls eliminates complexation. Eight substituents attached at the periphery of the monomers extend the surfaces and profoundly affect the binding free energies (-DeltaG values) of the complexes, which range from <1 to >9 kcal mol-1 in CDCl3 at temperatures -30 to 25 C. Peripheral substituents with rotational degrees of freedom inhibit homodimerization. Activation free energies (DeltaG) for five dimerizations ranged from 8 to 10 kcal mol-1 and for five dissociations from 10 to 15 kcal mol-1 (in CDCl3), suggesting their transition states to be very poorly solvated. The -DeltaG values for dimerization with notable exceptions increased dramatically with solvent polarity and polarizability. Enthalpies (DeltaH values) ranged from +6 to -8 kcal mol- and entropies (DeltaH values) from -6 to +40 cal mol-1 K-1. Some dimerizations were entropy driven and enthalpy opposed, pointing to large solvophobic effects in organic media.

2,3-Dimercaptoquinoxaline 1 was allowed to react with some dihalo compounds and chloroanil using PTC technique to afford the corresponding polyfused quinoxalines 2a-d. The reaction of compound 1 with different monohalo compounds under the same PTC conditions or in refluxing ethanol in presence of piperidine catalyst gave (1,4)dithiino-, thieno-, (1,4)thiazino-, and pyrroloquinoxalines 3a-5b. The addition of compound 1 to alpha,beta-unsaturated nitriles was investigated to give the corresponding (1,5)dithiapinoquinoxalines 6a-7b and thiapinoquinoxalines 8a,b. The treatment of compound 1 with active nitriles furnished the corresponding thienoquinoxalines 9a-c and pyridazinoquinoxaline 10.
