Abstract: The invention relates generally to compounds which are allosteric modulators (e.g., negative and positive allosteric modulators, allosteric agonists, and ago-allosteric modulators) of the G protein coupled receptor apelin, also known as the APJ receptor. The APJ receptor compounds are derived from the it intracellular loop and domain of the APJ receptor. The invention also relates to the use of these APJ receptor compounds and pharmaceutical compositions comprising the APJ receptor compounds in the treatment of diseases and conditions associated with APJ receptor modulation, such as cardiovascular diseases, (e.g., hypertension and heart failure, such as congestive heart failure), cancer, diabetes, stem cell trafficking, fluid homeostasis, cell proliferation, immune function, obesity, metastatic disease, and HIV infection.

Abstract: The invention relates generally to compounds which are allosteric modulators {e.g., positive and negative allosteric modulators, and allosteric agonists) of the G protein coupled receptor for stromal derived factor 1 (SDF-I), also known as the CXCR4 receptor. The CXCR4 receptor compounds are derived from the intracellular loops and domains of the CXCR4 receptor. The invention also relates to the use of these CXCR4 receptor compounds and pharmaceutical compositions comprising the CXCR4 receptor compounds in the treatment of diseases and conditions associated with CXCR4 modulation such as bone marrow transplantation, chemosensitization, cancer, metastatic disease (e.g., cancer), auto-immune disease (e.g., rheumatoid arthritis), fibrosis disease (e.g., pulmonary), AIDS infection, cardiovascular disease, uveitis, inflammatory diseases, celiac disease HIV infection and stem cell-based regenerative medicine.
