Levormeloxifene is a selective modulator of the estrogen receptor. It inhibits the production of vaginal tropoelastin and transforming growth factor-beta 1.
Onapristone, a progesterone receptor antagonist, is used potentially for the treatment of breast cancer, advanced prostate cancer, and inducer of vaginal bleeding.
FSL-1 TFA, a bacterial-derived toll-like receptor 2 6 (TLR2 6) agonist, enhances resistance to experimental HSV-2 infection[1]. FSL-1 TFA induces MMP-9 production through TLR2 and NF-κB AP-1 signaling pathways in monocytic THP-1 cells[2]. FSL-1 significantly reduces HSV-2 replication in human vaginal epithelial cells (EC)[1].FSL-1 induces significant resistance to experimental genital HSV-2 infection through elaboration of a specific cytokine response profile[1].FSL-1 (50 ng mL, 24 hours) induces MMP-9 expression at both mRNA and protein levels in human monocytic THP-1 cells[2].FSL-1 activates the MAP kinase NF-κB signaling pathway[2]. Cell Viability Assay[1] Cell Line: V11I, V12I or V19I immortalized human vaginal EC FSL-1 application significantly protectes against genital HSV-2 challenge in mice[1]. Animal Model: Female Swiss-Webster mice (weighing 20-25 g)[1] [1]. William A Rose 2nd, et al.

PACAP-related peptide (PRP) is an endogenous 29-amino acid peptide that belongs to the secretin/glucagon superfamily of peptides, which includes secretin , glucagon , glucagon-like peptide-1 , GLP-2 , and pituitary adenylate cyclase-activating polypeptide . It is expressed in rat hypothalamus as well as within the nerves of the median eminence, the anterior pituitary, bed nucleus of the stria terminalis, cerebellum, cerebral cortex, and amygdala. PRP is also expressed in vaginal, uterine cervical, uterine horn, fallopian tube, and ovarian tissues from the rat female genital tract and is present in extracts of male testis tissue.
