PMD, an insect repellent that can be derived from steam distillate residue of leaves of lemon eucalyptus. No QSAR studies are known in literature. We performed ab initio (RHF/6-31G**) study of PMD derivatives. A 3D pharmacophore for repellent activity was also developed. Results indicate lipophilicity, MEP separation and localized negative MEP by oxygen atom have roles for repellency. The pharmacophore is consistent and allowed design of more effective insect repellents.

For the experiment presented here, we used the same setup as for the initial multilaboratory study[1,2,3,4], but a special preparation process of the homeopathic drug involving dilution steps of 1: 50,000 and leading to thyroxin 10–11 – 10–21 was used.

Here we present a novel discovery-oriented high-throughput approach to the screening of allergen reactivates in crude biological extracts is presented using seafood allergens as an example. The CPGR workflow permits the effective screening of hundreds of putative allergens in parallel using minute amounts of patient serum and constitutes a cost-efficient allergen-specific antibody screening method for a routine diagnostic setting.

3D-QSAR Common Feature Pharmacophore Model for Polyphenols as Potential Anti-Malarial Agents

3D QSAR studies have been carried out on a series of polyphenols for their antimalarial activity using CATALYST program. Hypothesis with three features namely hydrophobic (1), hydrogen bond donor (1) and hydrogen bond acceptor (1) was found to the best, which mapped well with the most active and least active compound of the test set. This model can be used to develop drugs for malarial chemotherapy.

Purpose-Built LIMS for Life Sciences and High Throughput Screening Laboratories
, Thermo Fisher Scientific

Thermo Fisher Scientific Inc. have announced the availability of a new technical poster demonstrating the importance of configurability and flexibility in laboratory information management systems (LIMS) design for life sciences and high throughput screening applications.

High Content Image Analysis using a Laser Scanning Microplate Cytometer
Paul Wylie, Ben Schenker, Sarah Payne and Andrew Goulter, TTP Labtech

Microscope-based high-content instruments offer high optical resolution, however, the limited field of view afforded by their objective lenses can mean lengthy read times for some assays, especially where multiple image capture per well is required. Wherever possible, only a small percentage of the total number of cells present in a test well are analysed to keep plate read times at a minimum, which may not always be ideal. Microplate laser- scanning cytometers, such as TTP LabTech’s Acumen® eX3
