HTRF术语详解 详细 >>
FRET：指荧光共振能量转移，在供体和受体相互靠得很近时，光子能从一个受激发的荧光团（供体）转移到另一个荧光团（受体），并使后者发出荧光。
HTRF：均相时间分辨荧光，Homogeneous Time-Resolved Fluorescence ）是用来检测纯液相体系中待测物的一种常用方法。
背景（Background）：指在没有加入compound时检测到的信号值。
荧光受体（acceptor）：指在荧光团受到激光激发时，能发出特定波长的发射光的基团。HTRF®的能量受体均可为XL665和d2。

Identification of inhibitors for putative malaria drug targets among novel antimalarial compounds
By: Crowther GJ et al.
University of Washington, Seattle, WA, USA.
he efficacy of most marketed antimalarial drugs has been compromised by evolution of parasite resistance, underscoring an urgent need to find new drugs with new mechanisms of action. We have taken a high-throughput approach toward identifying novel antimalarial chemical inhibitors of prioritized drug targets for Plasmodium falciparum, excluding targets which are inhibited by currently used drugs. A screen of commercially available libraries identified 5655 low molecular weight compounds that inhibit growth of P. falciparum cultures with EC(50) values below 1.25μM. These compounds were then tested in 384- or 1536-well biochemical assays for activity against nine Plasmodium enzymes: adenylosuccinate synthetase (AdSS), choline kinase (CK), deoxyuridine triphosphate nucleotidohydrolase (dUTPase), glutamate dehydrogenase (GDH), guanylate kinase (GK), N-myristoyltransferase (NMT), orotidine 5'-monophosphate decarboxylase (OMPDC), farnesyl pyrophosphate synthase (FPPS) and S-adenosylhomocysteine hydrolase (SAHH). These enzymes were selected using TDRtargets.org, and are believed to have excellent potential as drug targets based on criteria such as their likely essentiality, druggability, and amenability to high-throughput biochemical screening. Six of these targets were inhibited by one or more of the antimalarial scaffolds and may have potential use in drug development, further target validation studies and exploration of P. falciparum biochemistry and biology.
