A series of 1-pentyl-1H-indol-3-yl-(1-naphthyl)methanes (9-11) and 2-methyl-1-pentyl-1H-indol-3-yl-(1-naphthyl)methanes (12-14) have been synthesized to investigate the hypothesis that cannabimimetic 3-(1-naphthoyl)indoles interact with the CB(1) receptor by hydrogen bonding to the carbonyl group. Indoles 9-11 have significant (K(i)=17-23nM) receptor(More)
The aim of the present study was to investigate the differences in biological characteristics between the rhoda-mine 123 (Rh123) high and Rh123 low subpopulations of the renal cancer cell line 786-O and to identify evidence for the existence of cancer stem cells in renal cell carcinoma (RCC) cells. In vitro cultured RCC 786-O cells were stained with Rh123,(More)
Quantum dots (QDs) have the potential to simplify the performance of multiplexed analysis. In this work, a novel protocol for performing a simultaneous dual-protein immunoassay, i.e. two lung cancer biomarkers, carcinoembryonic antigen (CEA) and neuron-specific enolase (NSE), based on dual-color QDs, is described. First, two capture antibodies (both with(More)
BACKGROUND The previous works about safety evaluation for constructed bladder tissue specific adenovirus are poorly documented. Thus, we investigated the biodistribution and body toxicity of bladder specific oncolytic adenovirus Ad-PSCAE-UPII-E1A (APU-E1A) and Ad-PSCAE-UPII-E1A-AR (APU-E1A-AR), providing meaningful information prior to embarking on human(More)
Chinese herbs Desmodium styracifolium (Ds) and Pyrrosiae petiolosa (Pp) have been widely used to treat urolithiasis with few side effects in traditional Chinese medicine (TCM). In vitro crystallization study has confirmed their prophylaxis of Calcium oxalate (CaO( x )) stones formation. However, little is known on their possible mechanisms in vivo. In the(More)
In an effort to improve indole-based CB(2) cannabinoid receptor ligands and also to develop SAR for both the CB(1) and CB(2) receptors, 47 indole derivatives were prepared and their CB(1) and CB(2) receptor affinities were determined. The indole derivatives include 1-propyl- and 1-pentyl-3-(1-naphthoyl)indoles both with and without a 2-methyl substituent.(More)
We have developed a novel sensitive chemiluminescence (CL) aptasensor for the target assay as exemplified by using adenosine as a model target. In this work, we have demonstrated the signaling mechanism to make detection based on magnetic separation and 3,4,5-trimethoxyl-phenylglyoxal (TMPG), a special CL reagent as the signaling molecule, which reacts(More)
We report on a highly sensitive aptameric assay system for the determination of IgE, where a special chemiluminescence (CL) reagent, 3,4,5-trimethoxylphenylglyoxal (TMPG), acts as the signaling molecule and polystyrene beads as the amplification platform. Briefly, a "sandwich-type" detection strategy is employed in our design, where magnetic beads(More)
The present study marks the first evaluation of combined application of the antioxidant N-acetylcysteine (NAC) and the free radical spin trap reagent, disodium 2,4-disulfophenyl-N-tert-butylnitrone (HPN-07), as a therapeutic approach for noise-induced hearing loss (NIHL). Pharmacokinetic studies and C-14 tracer experiments demonstrated that both compounds(More)
Quercetin, a flavonoid found in many fruits and vegetables, belongs to an extensive class of polyphenolic compounds. Previous studies reported that quercetin inhibits the proliferation of various cancer cells and tumor growth in animal models. We investigated the growth inhibition and colony formation of quercetin on three bladder cancer cells (EJ, J82 and(More)
