Natural Vibrio cholerae infection generates a robust B-cell response that wanes for T-cell independent antigens, suggesting that B-cell responses may be mediated in a T-cell dependent manner. Patients with cholera develop a memory-effector T-cell response to cholera antigens, and B-cell activation occurs after T-cell population expansion, suggesting that T-cells may play an important role in the development and maintenance of memory B-cell responses to T-cell dependent antigens.

To manage HTD data effectively and efficiently, we have developed a distributed virtual screening data manage- ment system (DVSDMS) by integrating the open source database MySQL into high throughput docking.

Screening of a natural compound library led to the identification of resorufin, as a highly selective and potent inhibitor for protein kinase CK2. Out of 52 kinases tested only CK2 was inhibited. The IC50 values determined for the CK2 holoenzymes were 1.5 µM and for the free catalytic subunits ca. 4 µM. In different cancer cell lines treatment with resorufin led to cell death and endogenous CK2 was inhibited.

The SRB assay was implemented on a TECAN Genesis workstation by optimizing cell numbers and liquid handling parameters. Anticancer drugs vinblastine, doxorubicin and 5-fluorouracil were used for standardizing the assay with a DU-145 cell line. To screen the antiproliferative activities of a series of stilbene derivatives, altogether 121 different stilbene structures, a plate layout was designed on 96-well format.

We developed and validated a high throughput in vitro setting to experimentally determine hSA and Orosomucoid affinities, fraction absorbed, Log BBB and Redox potential of NCEs using gold nanoparticles functionalized with proteins, lipids or conductive polymers. Such automated ADME assays provide means for more objective decisions in early drug discovery.
