The complex trans,cis-[RuCl2(PPh3)2(ampi)] (2) was prepared by reaction of RuCl2(PPh3)3 with 2-aminomethylpiperidine(ampi) (1). [RuCl2(PPh 2(CH2)nPPh2)(ampi) (n = 3, 4, 5)] (3-5) were synthesized by displacement of two PPh3 with chelating phosphine ligands. All complexes (2-5) were characterized by 1 H, 13C, 31P NMR, IR and UV-visible spectroscopy and elemental analysis. They were found to be efficient catalysts for transfer hydrogen reactions.

The first organocatalytic enantioselective C-H alkenylation and arylation reactions of N-carbamoyl tetrahydropyridines and tetrahydro-beta-carbolines (THCs) are described. The metal-free processes represent an efficient and straightforward approach to a variety of structurally and electronically diverse alpha-substituted tetrahydropyridines and THCs in good yields with excellent regio- and enantioselectivities. Preliminary control experiments provide important insights into the reaction mechanism.

Quinoxalines belong to the N-containing heterocyclic compounds that stand out as having promising biological activity due to their privileged scaffold. In this work, we report the synthesis, antileishmanial, and antitrypanosomal properties of 46 new 2,3-disubstituted quinoxaline and 40 previously reported derivatives. Among all of the compounds screened for in vitro activity against epimastigotes and trypomastigotes of Trypanosoma cruzi and promastigotes of Leishmania amazonensis as well as mammalian toxicity on LLCMK2 cells and J774 macrophages, analogues from series 5, 6, 7, 9, 12, and 13 displayed high activity at micromolar IC50 and EC50 concentrations. Sixteen quinoxaline derivatives were selected and evaluated on T. cruzi and/or L. amazonensis amastigotes. The most active compounds were 6a-b and 7d-e, on all evolutive forms of L. amazonensis and T. cruzi evaluated with IC50 values 0.1-0.8 1/4M on promastigotes and epimastigotes 1.4-8.6 on amastigotes. Compounds 5k, 12b and 13a were the most selective (SI Combining double low line 19.5-38.4) on amastigotes of T. cruzi. In general their activity was directly related to the methylsulfoxyl, methylsulfonyl, and amine groups as well as the presence of chorine or bromine in the molecules. The current results indicate that these quinoxaline derivatives are novel and promising agents for further development towards a treatment for Chagasg disease and leishmaniasis.

Reference of 149669-43-2, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.149669-43-2, Name is 5-Fluoro-3-(piperidin-4-yl)-1H-indole, molecular formula is C13H15FN2.

As part of our research program toward new, potential antidepressants, a series of unsymmetrical ureas has been prepared and evaluated as 5-HT reuptake inhibitors with 5-HT(1B/1D) antagonistic activities. The design of these compounds was based on coupling of various indole derivatives, previously shown to inhibit 5-HT reuptake, to three different aniline moieties, which are part of known 5-HT(1B/1D) ligands. Binding experiments in rat frontal cortex using [125I]iodocyanopindolol, in calf striatum using [3H]5-HT, and in rat hippocampus using [3H]8-OH-DPAT as radioligands, respectively, revealed significantly higher affinity at the 5-HT(1B) receptor as compared to the affinities for the 5-HT(1A) and 5-HT(1D) receptors for a number of compounds, among them 4-(5-fluoro-1H-indol-3-yl)piperidine-1- carboxylic acid [4-methoxy-3(4-methylpiperazin-1-yl)phenyl]amide (5), the corresponding 4-fluoro-1H-indol-3-yl analogue 21a, and the corresponding 6- fluoro-1H-indol-3-yl analogue 21b. Conformational restriction of the aniline moiety in 5 only slightly enhanced the 5-HT(1B) affinity, whereas introduction of an aniline moiety with higher conformational flexibility resulted in a less potent 5-HT(1B) receptor ligand as compared to 5. The functional 5-HT(1B/1D) antagonistic activity was investigated using the rabbit saphenous vein model as well as the [3H]5-HT release from guinea pig cortical slices. All new compounds tested in the rabbit saphenous vein model were shown to antagonize the sumatriptan-evoked contractile responses with pA2 values ranging from 7.3 to 8.7. These observations were consistent with the results of the cortical slice model, in which the ureas were found to block the sumatriptan-induced inhibition of potassium-evoked [3H]5-HT release. The 5-HT reuptake inhibition of the ureas determined in rat brain synaptosomes was found to be either increased or decreased as compared to the uncoupled indole derivatives indicating that the reuptake inhibition shown by the ureas is not only due to the indole part but also affected by the aniline moiety of the molecule. Among this series of compounds described the ureas 5, 21a, and 21b seem to be the most interesting candidates showing both 5-HT reuptake inhibition and 5-HT(1B/1D) antagonism in vitro. This dual pharmacological profile should in theory lead to a pronounced enhancement in serotonergic neurotransmission and consequently to a more efficient treatment of depression.
