A series of eight new titanocene dichloride derivatives has been synthesised and characterized. Four compounds from the series are lypophilic indole-functionalised titanocenes and four are hydrochloride salts of their dimethylaminomethyl-functionalised counterparts, which are water soluble. The compounds were tested for their in vitro cytotoxicities against the human kidney cancer cell line CAKI-1 and their results are compared with previously synthesised structural analogues. Surprisingly, two of the compounds showed no activity against the CAKI-1 cell line; however six compounds exhibited medium to high potency with IC50 values as low as 7.0 muM. These six complexes were tested further on this cell line using the co-solvent Soluphor P, which has been shown to improve both solubility and cytotoxicity of similar complexes. One of the compounds carrying a N-methylindole-substituent was obtained in the form of single crystals and allowed for the characterisation by X-ray crystallography; the compound crystallised in the space group P21/n (#14) with four molecules present in the monoclinic unit cell.

The non-P1 and non-P2 muscle relaxant effect of ATP in rabbit thoracic aorta has recently been attributed to a putative P3 purinoceptor, which is activated by either adenosine or ATP. Since the physiological roles of this putative P3 purinoceptor and of a new [3H]-5?-N-ethylcarboxamidoadenosine (NECA)-binding protein from rat brain membranes called P3 purinoceptor-like protein (P3LP), due to its ligand specificity, have not been fully elucidated, we needed a specific ligand to obtain further information about the receptor. We examined the structure-activity relationship (SAR) of various 5?-N-substituted-carboxamidoadenosine derivatives toward P3LP and discovered a hydrophobic binding region near the 5?-N-substituted-carboxamide group. From the linear alkyl N-substituted derivatives, the N-n-pentyl derivative 10 was found to be the most potent ligand with a Ki value of 12 nM. In the series of the N-cycloalkyl derivatives, the N-cyclohexyl derivative 27 was the strongest ligand with a Ki value of 18 nM. On the other hand, the N-substituents having branched alkyl side chains and bulky cycloalkyl groups did not show any potent affinities for P3LP. Therefore, the hydrophobic pocket accommodates approximately a 10-carbon-atom-long linear alkyl side chain, while a considerably stronger hydrophobic binding region of about a 5-carbon-atom-long depth exists near the nitrogen atom of the amide group. This pocket also allows substitution with bulky hydrophobic groups since the 5?-N-cycloalkyl derivatives have high affinities. We also examined the receptor selectivity for the selected nucleosides 10 and 27 with 1 [9-(6,7-dideoxy-beta-D-allohept-5-ynofuranosyl)adenine, HAK2701] and NECA versus P1 purinoceptor subtypes, such as adenosine A1, A2A, A2B, and A3 receptors, and found that 27 is the most selective ligand for P3LP.

In this study a microwave-assisted method was applied for the synthesis of novel 9-(substituted indolyl)-3,4,6,7-tetrahydroacridine-1,8-(2H,5H,9H,10H)- dione derivatives. The structures of the compounds were confirmed by spectral methods including X-ray studies and elemental analysis. The Ema x and pD2 values of the compounds and pinacidil were determined on noradrenaline precontracted tissues of isolated strips of rabbit gastric fundus smooth muscle. The obtained results indicated that some compounds and pinacidil produced concentration-dependent relaxation on the strips. The efficacy of compound 9 was higher than pinacidil. Docking studies were carried out to understand the interactions of the compounds with the active site of potassium channel. Methyl substituents on the acridine backbone and bromine atom on the indole ring led to more active compounds.

Racemic 5-(trans-2-aminomethylcyclopropyl)indoles, 5-(trans-2- aminomethylcyclopentyl) indoles, and 5-(cis-2-aminomethylcyclopentyl)indoles were synthesized and evaluated as selective serotonin reuptake inhibitors. These analogs followed SAR trends similar to those previously reported for 3-cycloalkyl substituted indoles. The most potent analogs exhibited single digit nanomolar inhibition at the human serotonin transporter but were 10-fold less active than the previously reported compounds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 90271-86-6, you can also check out more blogs about90271-86-6

In some cases, the catalyzed mechanism may include additional steps.In a article, 20289-26-3, molcular formula is C15H13NO, introducing its new discovery. name: 4-Benzyloxyindole

Friedel-Crafts alylation of indole and its derivatives with a variety of electron-deficient alkenes catalyzed by Mg and Ca salts has been studied. The dependence of the results on the nature of the starting olefins, substituents on indole, and Michael acceptors, as well as on the composition of the Lewis acid is discussed. High yields of the addition products were achieved in the addition of indole to beta,gamma-unsaturated alpha-keto esters and coumarin derivatives, some nitroolefins, and arylidenemalonates. Reactions involving arylidenemalonates were found to be the most versatile and smooth, the best yields reached 92%. Among the Mg and Ca salts tested, magnesium iodide (MgI 2) proved to be the most appropriate catalyst in the addition to various unsaturated carbonyl compounds, while calcium triflimide [Ca(NTf 2) 2 ] efficiently catalyzed the addition to nitroolefins.

Enantioselective total synthesis of the biologically important indole alkaloids (+)-lysergol, (+)-isolysergol, and (+)-lysergic acid is described. Key features of these total synthesis include (1) a facile synthesis of a chiral 1,3-amino alcohol via the Pd(0)- and In(I)-mediated reductive coupling reaction between l-serine-derived 2-ethynylaziridine and formaldehyde; (2) the Cr(II)/Ni(0)-mediated Nozaki-Hiyama-Kishi (NHK) reaction of an indole-3-acetaldehyde with iodoalkyne; and (3) Pd(0)-catalyzed domino cyclization of an allene bearing amino and bromoindolyl groups. This domino cyclization enabled direct construction of the C/D ring system of the ergot alkaloids skeleton, as well as the creation of the C5 stereogenic center with transfer of the allenic axial chirality to the central chirality.
