A series of symmetry-based HIV protease inhibitors was designed and synthesized. Modification of the core regiochemistry and stereochemistry significantly affected the potency, metabolic stability, and oral bioavailability of the inhibitors, as did the variation of a pendent arylmethyl P3 group. Optimization led to the selection of two compounds, 10c (A-790742) and 9d (A-792611), for advancement to preclinical studies.

In the liver glucocorticoid receptor antagonism suppresses hepatic glucose production decreasing plasma glucose levels; however, extrahepatic antagonism produces several undesirable side effects including activation of the hypothalamic pituitary adrenal axis. A series of nonsteroidal passive N-(3-dibenzylamino-2-alkyl-phenyl)-methanesulfonamide glucocorticoid receptor modulators was discovered.

Methods: The CARE Group consisted of team members from 4 participating neonatal intensive care units (NICUs). All CARE Group members chose to work on multidisciplinary teamwork for the duration of the Neonatal Intensive Care Quality Improvement Collaborative Year 2000.
Community based organizations (CBOs) play a frontline role in HIV/AIDS prevention activities. CBOs face formidable challenges to effective delivery of HIV prevention services including client characteristics such as homelessness and CBO characteristics such as limited resources and staff turnover. Despite these obstacles, CBOs are generally well positioned to deliver services to specific high-risk populations because they understand their local communities and are connected to the groups they serve.
