The C-X-C motif ligand 8 and C-X-C chemokine receptor 2 (CXCL8-CXCR2) axis is involved in pathogenesis of various diseases including inflammation and cancers. Various CXCR2 antagonists are under development for several diseases. Our previous high-throughput cell-based assay specific for CXCR2 has identified a pyrimidine-based compound CX797 acting on CXCR2 down-stream signaling. A lead optimization campaign through scaffold-hopping strategy led to a series of 2-thioureidothiophene-3-carboxylates (TUTP) as novel CXCR2 antagonists. Structure-activity relationship study of TUTPs led to the identification of compound 52 that significantly inhibited CXCR2-mediated β-arrestin recruitment signaling (IC50 = 1.1±0.01 μM) with negligible effect on CXCL8-mediated cAMP signaling and calcium flux. Similar to the known CXCR2 antagonist SB265610, compound 52 inhibited CXCL8-CXCR2 induced phosphorylation of ERK1/2. TUTP compounds also inhibited CXCL8-mediated cell migration and showed synergy with doxorubicin in ovarian cancer cells, thereby supporting TUTPs as promising compounds for cancer treatment.
Rab7 GTPase inhibitors and related methods of treatment

Page/Page column, (2014/07/08)
This invention relates to compounds and their use as inhibitors or activators of Rab7 GTPase to treat or prevent the onset of Rab 7 GTPase-associated disorders such as neuropathies, cancer, metabolic diseases of bone and lipid storage. The invention is also applicable to infectious diseases where Rab7 is inactivated or its protein-protein interactions are modulated to facilitate intracellular survival of pathogens. The compound described acts as a competitive inhibitor of nucleotide binding and as such also has utility as a scaffold for targeting other small GTPases. In one aspect, methods of treatment of the invention are used to treat or prevent the onset of hereditary sensory neuropathies such as Charcot-Marie-Tooth type 2B disease. Related pharmaceutical compositions, assays, and drug screens are also provided.
