Research Description
Cyclooxygenase-2 (COX-2) catalyzes the committed step in the biosynthesis of prostaglandins, thromboxane, and prostacyclin. COX-2 is not expressed in most normal tissues but is present in inflammatory lesions and tumors. The expression of COX-2 appears to be an early event in tumorigenesis that plays a role in tumor progression. COX-2 mRNA and protein are detectable in a significant percentage of precursor lesions (e.g., colon polyps, Barrett’s esophagus) and an even higher percentage of malignant tumors (e.g., colon adenocarcinoma, esophageal adenocarcinoma). The other form of cyclooxygenase, COX-1, does not appear to be elevated in tumors with the exception of ovarian carcinomas. Thus, COX-2 may be responsible for the significant increase in prostaglandin biosynthesis observed in many human tumors. COX-2 is the molecular target for the anti-inflammatory, analgesic, and antipyretic effects of non-steroidal anti-inflammatory drugs (NSAIDs) and for the COX-2-selective inhibitors, celecoxib and rofecoxib. NSAIDs exhibit varying selectivity for COX-2 and COX-1 but, in general, none of them displays high selectivity for COX-2. NSAIDs and COX-2-selective inhibitors possess cancer chemopreventive activity, retard the growth of human tumor xenografts in nude mice, and induce polyp regression in individuals with familial polyposis. These activities have been attributed to their ability to inhibit COX-2. The elevated expression of COX-2 in benign and malignant tumors and the apparent functional role that the enzyme plays in tumor growth suggests that COX-2 is an attractive target for the development of tumor-selective imaging agents. Our laboratory has developed a novel approach that allows the facile conversion of non-selective NSAIDs into highly selective COX-2 inhibitors. This is accomplished by conversion of the carboxylic acid functional group, common to most NSAIDs, to an amide or ester. Extensive structure-activity studies indicate that a diverse range of functional groups can be tethered to an NSAID through a stable amide linkage with retention of potency and selectivity for COX-2 inhibition. Indeed, it is extremely rare that the specific binding of an enzyme inhibitor allows such a wide range of structural flexibility. Jashim is interested in developing fluorescent or radiolabeled COX-2-targeted agents that selectively label COX-2 expressing tumor cells in vitro and in vivo. COX-2-selective imaging agents can be developed specifically for use with the optical modalities, near infrared (NIR) fluoresecence and two-photon microscopy, and the radiologic modalities, SPECT and PET, and that these agents can be used to monitor COX-2 expression during tumor initiation and progression. These imaging approaches lead to determine the predictive value of COX-2 expression on the response to therapy, the effects of therapy on COX-2 expression, and the usefulness of imaging to design therapy based on COX-2 inhibition. The results of these experiments will form the framework for the rapid development of COX-2-targeted imaging agents for the clinical cancer detection in the early stage.
