Journal ArticleDOI
Conjugation of Cisplatin Analogues and Cyclooxygenase Inhibitors to Overcome Cisplatin Resistance
Wilma Neumann,Brenda C. Crews,Menyhárt B. Sárosi,Cristina Daniel,Kebreab Ghebreselasie,Matthias Scholz,Matthias Scholz,Lawrence J. Marnett,Evamarie Hey-Hawkins +8 more
TL;DR: These conjugates are important tools for the elucidation of the direct influence of COX inhibitors on platinum‐based anticancer drugs in tumor cells and seem to facilitate cellular accumulation of the platinum drugs and thus improve the efficacy of the antitumor agents.
Journal ArticleDOI
Chemical stability of 2-arachidonylglycerol under biological conditions
TL;DR: The results indicate that 2-AG is readily converted to 1(3)-AG under conditions commonly used to study receptor-ligand interactions, findings that have significant implications for the interpretation of relative ligand potency between the two isomers.
Journal ArticleDOI
Oxicams Bind in a Novel Mode to the Cyclooxygenase Active Site via a Two-water-mediated H-bonding Network
Shu Xu,Daniel J. Hermanson,Surajit Banerjee,Surajit Banerjee,Kebreab Ghebreselasie,Gina M. Clayton,R. Michael Garavito,Lawrence J. Marnett +7 more
TL;DR: Structures reveal that the oxicams bind to the active site of COX-2 using a binding pose not seen with other NSAIDs through two highly coordinated water molecules.
Journal ArticleDOI
Design, Synthesis, and Structure–Activity Relationship Studies of Fluorescent Inhibitors of Cycloxygenase-2 as Targeted Optical Imaging Agents
TL;DR: The SAR study revealed that indomethacin conjugates are the best COX-2-targeted agents compared to the other carboxylic acid-containing nonsteroidal anti-inflammatory drugs (NSAIDs) or COX2-selective inhibitors (COXIBs), and an n-butyldiamide linker is optimal for tethering bulky fluorescent functionalities onto the NSAID or COxIB cores.
Journal ArticleDOI
Fluorinated COX-2 inhibitors as agents in PET imaging of inflammation and cancer.
Md. Jashim Uddin,Brenda C. Crews,Kebreab Ghebreselasie,Imran Huda,Philip J. Kingsley,Mohammad Sib Ansari,Mohammed N. Tantawy,Jeffery Reese,Lawrence J. Marnett +8 more
TL;DR: The in vitro and in vivo properties of compound 7 suggest it will be a useful probe for early detection of cancer and for evaluation of the COX-2 status of premalignant and malignant tumors.
