Nonpeptide ligands that target peptide-activated GPCRs in inflammation
The focus of this review is on G protein-coupled receptors (GPCRs) for which nonpeptidic ligands are known and have been evaluated for the treatment of inflammatory conditions. GPCRs are the most prevalent class of cell surface proteins in pharmaceutical research today, and GPCR-targeting drugs account for one tenth of worldwide pharmaceutical sales. Of over 800 human GPCRs identified to date, several hundred are activated by peptides/proteins and just over 30 of these have been identified so far as potential therapeutic targets for the treatment of inflammatory diseases. This review highlights those GPCRs and over 60 structurally diverse nonpeptidic compounds that interact with them and display pro- or anti-inflammatory properties. Among these GPCR targets are the receptors for peptides like bradykinin, chemokines, complement anaphylatoxins, corticotropin releasing factor, endothelins, melanocortins, tachykinins, urocortins, as well as the protease activated receptors (PARs). Other peptide activated GPCRs implicated in inflammation, like those that bind angiotensin II, N-formyl peptides, galanin, neuropeptide Y, opioids and oxytocin, are only briefly discussed because there is either less direct association with inflammation or few/no nonpeptidic anti inflammatory ligands known. While it is still very early in the development of anti inflammatory drugs that target GPCRs, there is already a wealth of information supporting their important roles as cellular sentries in inflammatory diseases. New opportunities are emerging to evaluate anti inflammatory activities of potent and selective GPCR-binding ligands, including those being developed for other disease indications. In summary, GPCRs deserve a great deal more attention as potential therapeutic targets in inflammatory diseases

Collaborative Development of Clinical Trials Education Programs for African-American Community-Based Organizations
This paper describes the use of a unique ”Learning and Feedback” approach to tailor cancer clinical trials education programs for Community Bridges, a peer training intervention designed for African American communities in North Carolina. Generic community education modules were demonstrated with key community leaders who were designated as trainers. Quantitative and qualitative assessments were provided on understanding of content, comfort with material and cultural relevance. The generic materials were adapted into three revised modules, all featuring key messages about cancer clinical trials, discussion regarding distrust of medical research, common misconceptions about trials, patient protections, and a call to action to prompt increased inquiry about locally available trials. The revised modules were then used as part of a train-the-trainer program with 12 African American community leaders. ENACCT’s use of the Learning and Feedback process is an innovative method for culturally adapting clinical trials education
