“…Papilloma viruses are a group of small DNA tumor viruses that infect a wide variety of mammalian cells. They are the causative agents of benign proliferative lesions of the skin or mucosa, and certain strains have been implicated in the development of cervical carcinomas and other malignancies. , All of the papillomaviruses encode a DNA-binding protein, E2, that regulates the transcription of several viral genes and, in conjunction with the E1 protein, is required for viral replication. − …”

NMR-Based Discovery of Lead Inhibitors That Block DNA Binding of the Human Papillomavirus E2 Protein

The E2 protein is required for the replication of human papillomaviruses (HPVs), which are responsible for anogenital warts and cervical carcinomas. Using an NMR-based screen, we tested compounds for binding to the DNA-binding domain of the HPV-E2 protein. Three classes of compounds were identified which bound to two distinct sites on the protein. Biphenyl and biphenyl ether compounds containing a carboxylic acid bind to a site near the DNA recognition helix and inhibit the binding of E2 to DNA. Benzophenone-containing compounds which lack a carboxylic acid group bind to the beta-barrel formed by the dimer interface and exhibit negligible effects on the binding of E2 to DNA. Structure-activity relationships from the biphenyl and biphenyl ether compounds were combined to produce a compound [5-(3'-(3",5"-dichlorophenoxy)-phenyl)-2,4-pentadienoic acid] with an IC50 value of approximately 10 microM. This compound represents a useful lead for the development of antiviral agents that interfere with HPV replication and further illustrates the usefulness of the SAR by NMR method in the drug discovery process.

“…G enital infection by the human papillomavirus (HPV) is more frequent in teenagers from 15 years on, with a maximum prevalence till 25 years approximately. Very unusual in childhood and after 60 years age (1,7,14). Data obtained both in Europe and United States of America suggest that during the last 20 years the HPV infections increased considerably, as well as other sexually transmitted diseases (7).…”

“…Data obtained both in Europe and United States of America suggest that during the last 20 years the HPV infections increased considerably, as well as other sexually transmitted diseases (7). Since 1982 a high increase in the infections diagnose has been experienced, based on the great number of cytologic, colposcope and histopathological examinations of the uterine coli injuries (1,7). According to Biro and Hillard (1990) the infection by HPV, even being frequent in teenagers, only 10% of the cases are symptomatic.…”

Infection by the human papillomavirus in teenagers sexually active: clinic and subclinic manifestations

This research studies the association of the cervical condyloma with the intraepithelial neoplasia, during sex activity, pregnancy, diagnose methods, cytology and colposcopy in teenagers. The objective of this research is to study the propaedeutics for the uterine coli condyloma diagnose in a group of teenagers. For this purpose, we have studied 131 teenagers sexually active with ages between 14 and 19 years and presenting histologically confirmed uterine coli condyloma. Association with intraepithelial neoplasia, sexual activity duration, method of diagnose, pregnancy analysis, cytology and colposcopy results and association with vulva and vagina injuries were evaluated. The high association rate with condyloma and intraepithelial neoplasia after a short time of sexual activity and the none presence of macroscopic warts in the genital organs in 80% of cases presenting cervical condyloma, demonstrate that: a more careful investigation with colposcopy and biopsy of the inferior genitals of the women-teenagers sexually active is needed, when presenting modified cervical cytology.
