Pharmacophore Mapping of Flavone Derivatives for Aromatase Inhibiton
Poster Apr 17, 2007
The study explores the structural requirements of flavones for inhibition of aromatase activity. The QSAR analysis generates the model (R2=0.944) that shows the importance of flavone ring and with molecular lipophilicity. Presence of additional aromatic ring and m-hydroxy substitution on that ring increases inhibitory activity. Space modeling study (R=0.941) further adjudged the presence of hydrogen bond acceptor, hydrophobic and aromatic ring and critical distance among features for the inhibitory activity.
We show that network analysis of co-localized ions from mass spectrometry imaging data provides a detailed chemo-spatial insight into the metabolic heterogeneity of tumors. Furthermore, module preservation analysis between colorectal cancer patients with and without metastatic recurrence suggests hypotheses on the nature of the different local metabolic pathways.READ MORE
Angioimmunoblastic T-cell lymphoma (AITL) is a common type of peripheral T-cell lymphoma. AITL can be missed until lymphadenopathy develops in patients initially presenting with skin lesions, as skin biopsy may lack conclusive findings. Our case highlights the extranodal presentation of AITL with cutaneous lesions displaying the TFH phenotype.READ MORE
