working together to develop anticancer agents and antiangiogenic drugs<br />

with favorable side effect profiles. In May <strong>2001</strong>, we commenced<br />

Phase II clinical research of the sulfonamide deriviative E7070, a new<br />

type of anticancer agent. We are also developing E7389, an anticancer<br />

agent derived from naturally occurring substances, in collaboration with<br />

the U.S. National Cancer Institute.<br />

The <strong>Eisai</strong> Research Institute of Boston has developed E5564, a<br />

fully synthesized compound for treating sepsis. This substance, an<br />

endotoxin antagonist, has been developed to block the activities of<br />

bacterial endotoxins that play a key role in the development of sepsis.<br />

Substances under development in Japan include the rheumatoid<br />

arthritis treatment, T-614, genetically engineered tumor necrosis<br />

factor (TNF-α) antagonist D2E7 and the obesity management<br />

compound KES524 (sibutramine).<br />

Technology Platforms for Drug Discovery<br />

Bioinformatics* 1 plays an important role in genomics-based drug<br />

discovery. At <strong>Eisai</strong>, bioinformatics focuses on the construction of a<br />

database valuable for daily research activities and the development of<br />

proprietary software tools for data analysis. Our bioinformatics capabilities<br />

have been significantly reinforced via the agreement with<br />

Incyte Genomics Inc. in March <strong>2001</strong>, which permits access to their<br />

proprietary cDNA (complementary DNA) database.<br />

Transcriptomics* 2 and proteomics* 3 , which are used for target<br />

validation and the functional analysis of genes, are also important<br />

technologies in genomics-based drug discovery. Utilizing these cutting<br />

edge technologies, together with genetics using model organisms—<br />

such as yeast and the nematode C. elegans—and knockout* 4 and<br />

transgenic* 5 technologies, we are conducting innovative genomicsbased<br />

drug discovery research.<br />

<strong>Eisai</strong> <strong>Annual</strong> <strong>Report</strong> <strong>2001</strong><br />

analyzing vast data sets of genome<br />

sequences and proteins for the discovery<br />

of target genes.<br />

* 2Transcriptomics: Analysis of gene expression profiles.<br />

* 3Proteomics: Analysis of whole protein expression.<br />

* 4Knockout technologies:<br />

Technology to produce model animals with<br />

defects in specific genes in order to analyze<br />

the function of the gene by observing the<br />

resulting phenotype.<br />

* 5Transgenic technologies:<br />

Technology to introduce foreign gene(s)<br />

into model animals, for analysis of the<br />

function of the gene and for construction<br />

of disease models.<br />
