3D-QSAR Common Feature Pharmacophore Model for Polyphenols as Potential Anti-Malarial Agents
Shruti Saxena, Amit K. Gupta & Mridula Saxena

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.

SOME BIOLOGICAL PROPERTIES OF TRITERPENOID ACIDS
S.N. Morozkina, O.I. Antimonova, E.M. Eremenko*, A.G. Shavva

Ursolic and betulinic acids acids induce the processes of apoptosis. We tested the risk of osteoporosis induction under influence of triterpenoids, since they can interact with glucocorticoid receptors. In experiments on oviriectomized rats we found that acids do not show any negative influence on percentage of mineral components in the femur and have cholesterol-lowering action under experimental conditions.

THE OSTEOPROTECTIVE ACTION OF 6-OXA-8a-ANALOGUES OF STEROID ESTROGENS
A.G. Shavva, V.N. Belov, A.Yu. Solovyev, S.N. Morozkina

We synthesized fourteen 6-oxa-8a-estrogens analogues and investigated osteoprotective and uterotropic actions. We demonstrated correlation: every modification in structure of 6-oxa-8-analogues leading to strong (>30%) reduction of uterotropic action induces slump of osteoprotective activity. This allows to make conclusion: main biotarget, responsible for appearance of osteoprotective action is a-estrogen receptor. We found steroid estrogen analogues with cholesterol-lowering properties without u

Lead Optimization Computational Protocol at PDB Scale to Rationally Optimize Attachments to a Given Kinase Inhibitor Scaffold
Moriaud F., Henry T., Adcock S.A., Vorotynsev A.M., Martin L., Doppelt O.

We’ve used MED-SuMo to query and mine the Protein’s Surface Chemical Functions surrounding fragments of PDB ligands, seeking similarities with the kinase of interest (Vegfr DFGout, pdb code 2oh4, ligand code GIG) and collecting a library of 1129 unique fragments positioned in the vegfr’s active site and annotated with the counts of contacts and h-bonds. With them we optimize a substructure of the GIG ligand to find others DFGout ligands.

Caveolin-1 Expression as a Possible Biomarker in Pancreatic Cancer Diagnosis
C. Tanase, E. Raducan, L. Albulescu, E. Codorean, M.I. Nicolescu, D.I. Popescu, M.L. Cruceru and A.C. Popa

Caveolin1 (Cav-1) function either as a tumor supressor or as a promoter of metastasis. Overexpresion of cav-1 was correlated with: tumoral grading, proliferration markers (Ki67, p53), serum tumor markers (CEA, CA19.9) and angiogenic markers (VEGF, bFGF).

Changes in the Gene Expression of mRNA Transcripts for Insulin like Growth Factor, their receptor and Facilitative Glucose Transporter in IVM Oocytes
S.C. Gupta, Neelam Gupta and Alok Pandey

The cDNA libraries from single oocytes and pre-implantation buffalo embryos from 2 cell stage to blastocyst were established. Relative expression studied with RT-PCR of IGF-I showed an increase at 12h and decline at 24h of IVM oocytes. IGF-IR was expressed at cleavage stages to blastocyts. Glut-I was expressed in IVM oocytes and SCNT embryos at all stages. Gene expression of IGF-I, IGF-IR and Glut-I plays an important role in SCNT embryo production.

Development of a Lab-on-a-Chip for the Characterization of Human Cells
Richter, L., Stepper, C., Mak, A., Brückl, H. and Ertl, P.

Cell chips are developed to continuously monitor mammalian cell population dynamics in a non-invasive manner. In the presented work we describe the design, fabrication and characterization of a lab-on-a-chip for quantitative cell analysis.

Label-free Identification of Microorganisms using a Contact-less Dielectric Microsensor
Ertl, P., Richter, L., Reinthaler, A., Stepper, C., Mak, A., Kast, M., Heer, R. and Brückl, H.

Microfabricated biochips are developed to continuously monitor cell population dynamics in a non-invasive manner. In the presented work we describe the novel combination of contact-less dielectric microsensors and microfluidics to promote biofilm formation for quantitative cell analysis.
