A novel series of potent benzoxazole mPGES-1 inhibitors has been derived from a hit from a high throughput screen. Compound 37 displays mPGES-1 inhibition in an enzyme assay (0.018 μM) and PGE-2 inhibition in a cell-based assay (0.

Lipid kinases are central players in lipid signaling pathways involved in inflammation, tumorigenesis, and metabolic syndrome. A number of these kinase targets have proven difficult to investigate in higher throughput cell-free assay systems. This challenge is partially due to specific substrate interaction requirements for several of the lipid kinase family members and the resulting incompatibility of these substrates with most established, homogeneous assay formats.

Human immunodeficiency virus-type 1 (HIV-1) is a sexually transmitted pathogen that can infect cells in the female reproductive tract (FRT). The mechanism of viral transmission within the FRT and the mode of viral spread to the periphery are not well understood. To characterize the frequency of potential targets of HIV infection within the FRT, we performed a systematic study of the expression of HIV receptors (CD4, galactosyl ceramide (GalCer)) and coreceptors (CXCR4 and CCR5) on epithelial cells and leucocytes from the ectocervix.

Article Synopsis
  • * The study found that uterine epithelial cells express several important HIV receptors (CD4, CXCR4, CCR5, and GalC) that vary in their levels throughout the menstrual cycle, with significant changes during the proliferative and secretory phases.
  • * This hormonal influence on receptor expression may increase a woman's vulnerability to HIV infection at different times in her cycle and could also explain why certain HIV-1 strains are more commonly transmitted to women.
