  • Patent number: 12233082
    Abstract: HIV pre-exposure prophylaxis (PrEP) has been available for nearly a decade. Patients can take a pill comprising of multiple antiviral agents that, if exposed to HIV, will prevent a permanent viral infection with an extremely high success rate. However, the use of PrEP antivirals has been linked to higher rates of STIs including HSV-1, HSV-2, Infectious Mononucleosis, chlamydia, gonorrhea, trichomanias, and syphilis. In particular, Herpes Simplex Viruses 1 and 2 can cause symptoms including oral or genital sores, while mono, caused by the Epstein-Barr Virus, can cause prolonged sickness. This disclosure utilizes two or more antiviral agents as a multi-use therapy for both suppressing a chronic herpesvirus infection while preventing an HIV infection. With this therapy, the odds of both acquiring HIV or spreading a herpesvirus are greatly reduced during human contact.

  • Patent number: 12161657
    Abstract: The invention is based on the discovery that combination therapy with 2-deoxyglucose, methotrexate, and wogonin provides a synergistic therapeutic effect in selectively killing cancer cells. Advantageously, the disclosed combinatorial therapy does not adversely affect normal, healthy cells. Although the individual compounds have been previously used in cancer treatment, the cited combination has been surprisingly found to selectively kill cancer cells, while not adversely affecting normal, healthy cells, especially those of the immune system. Further, the combination of the compounds produces a synergistic effect, with increased killing of cancer cells compared to each compound alone. Importantly, the combination caused the dying cancer cells to release three key markers of immunogenic cell death: HMGB1, ATP and calreticulin. Immunogenic cell death attracts and activates immune cells against cancers.
