The IC50 values of compounds 26, bearing two indoles, and 25, bearing only one indole, are 0.4 and 3 nM, respectively, against U937 leukemia cells in vitro. The IC50 values of compounds 28, bearing a butyramino group, and 27, bearing an acetamino group, are 0.008 and 0.4 nM, respectively, against U937 leukemia cells in vitro. Compound 29, bearing a double-bond linker, is about 4-fold more potent than 25, bearing no double-bond linker. Compound 26 is highly potent against all cell lines tested in the NCI in vitro screening with IC50 values in the 0.1-5 nM range for most cell lines. Compounds 26 and 30 are highly active against L1210 leukemia in mice. Compound 26 is also active against B16BL6 melanoma in mice.

A sensitive and accurate internal standard method to determine melatonin in mammalian tissues and physiological fluids has been described. This method includes the oxidation of melatonin to a highly fluorescent compound, N-[(6-methoxy-4-oxo-1,4-dihydroquinolin-3-yl)methyl]acetamide (6-MOQMA), and the determination of 6-MOQMA by a reversed-phase HPLC system. For the accurate and reliable determination, several melatonin analogs were designed and utilized as the internal standards, and ethyl and isopropyl analogs (having the corresponding alkyl group via the amide bond of melatonin instead of the methyl group) were found to be promising. Using these internal standards, highly accurate and sensitive determination could be accomplished using rat pineal gland samples, and the clear circadian rhythms are demonstrated. This method was also successfully applied to the determination of melatonin in a small amount (20 muL) of human saliva.

Figure Presented. Members of a series of 2,4,5-substituted pyrimidine derivatives were synthesized, and their interactions with tubulin and their antiproliferative activities against the human hepatocellular carcinoma cells of liver (BEL-7402) were evaluated. One member of this family, the indole-pyrimidine 4k, having an indole-aryl-substituted aminopyrimidine structure, was observed to be an excellent inhibitor of tubulin polymerization (IC50 = 0.79 muM) and to display significantly high antiproliferative activities against several cancer cell lines with IC 50 values ranging from 16 to 62 nM. This substance displayed a high propensity to arrests cells at the G2/M phase of the cell cycle (EC50 = 20 nM). In addition, 4k was found to competitively inhibit colchicine binding to tubulin, indicating that it binds to the colchicine-binding site of tubulin. The observations made in this investigation demonstrate that 2,4,5-substituted pyrimidines represent a new class of tubulin polymerization inhibitors with significant antiproliferative activity.

Appropriate and fine-tuned treatments of amorphous carbon (AC) involving aqua regia or concentrated HNO3 lead to oxidised carbon materials (oAC) which are able to catalyse 2,2?- and 3,3?-homocouplings of various functionalised indoles with outstanding activity. This newly developed carbocatalysed Csp2-Csp2 bond formation can be achieved under mild thermal conditions. The study on the scope of the reaction revealed that the reaction can be extended to the homocoupling of other substrates of high synthetic interest such as 2-naphthol, 2-functionalised benzofurans and benzothiofurans. The characterisation of oAC with XPS together with ad hoc experiments aimed at blocking the active site revealed that the presence and distribution of C-O functionalities is critical and correlates well with the catalytic activity. Such experiments provide solid support for elucidation of the mechanism, suggesting a quinone nature of the active C-O groups, which are spontaneously regenerated by oxygen. This is confirmed by the fact that 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) is able to promote the coupling in a stoichiometric fashion.

Arvelexin is one of major constituents of Brassica rapa that exerts anti-inflammatory activities. Several indolyl-3-acetonitrile derivatives were synthesized as arvelexin analogs and evaluated for their abilities to inhibit NO and PGE2 productions in LPS-induced RAW 264.7 cells. Of the indolyl-3-acetonitriles synthesized, compound 2k, which possesses a hydroxyl group at C-7 position of the indole ring and an N-methyl substituent, more potently inhibited NO and PGE2 productions and was less cytotoxic than arvelexin on macrophage cells.

A concise synthesis of pyrazolo[1,5-a]indole derivatives by copper-catalyzed aerobic oxygenation and cyclization of indoles with oxime acetates is described. This protocol represents an elegant example of N-1, C-2, and C-3 tri-functionalization of indoles in one-pot. Mechanistic studies indicate the reaction proceeds through a radical procedure. Oximes as an internal oxidant have been demonstrated to be a driver to initiate aerobic oxidation, which provides a new oxidative pattern for C-H functionalization even with high atom- and step-economy.
