New class of HCV inhibitors discovered by Eiger BioPharmaceuticals

Eiger BioPharmaceuticals, Inc., a biotechnology company developing antiviral therapies, announced today the publication of research from the labs of Stanford scientist and Eiger Founder, Dr. Jeffrey Glenn, M.D., Ph.D. and colleagues entitled, "Identification of a Novel Class of HCV Inhibitors". Published in the January 20th edition of Science and Translational Medicine, the research validates a domain, termed 4BAH2, within the non-structural protein (NS4B) of the HCV genome, as essential for HCV replication and describes the development of a high-throughput screen leading to the identification of small molecule inhibitors of 4BAH2.

Acyclovir does not reduce risk of HIV transmission for people infected with both HIV and HSV-2

A five-year international multi-center clinical trial has found that acyclovir, a drug widely used as a safe and effective treatment taken twice daily to suppress herpes simplex virus-2 (HSV-2), which is the most common cause of genital herpes, does not reduce the risk of HIV transmission when taken by people infected with both HIV and HSV-2.

New white paper examines how PCR mycoplasma tests and analysis save time and money

Contamination by mycoplasmal organisms is an ever-present concern in biopharmaceutical manufacturing. Their properties make them ready sources of contamination, while rendering them difficult and time-consuming to detect. A new free white paper, examines how PCR mycoplasma tests and analysis, deployed by a cutting-edge laboratory, minimizes testing delays and enable safe, high-volume biopharmaceutical production.
