A series of nucleoside phosphonate reverse transcriptase (RT) inhibitors have been synthesized and their anti-HIV activity and resistance profiles evaluated. The most potent analog [5-(6-amino-purin-9-yl)-2,5-dihydro-furan-2-yloxymethyl]-phosphonic acid (d4AP) demonstrated a HIV EC(50)=2.1 microM, and the most favorable resistance profile against HIV-1 variants with K65R, M184V or multiple thymidine analog mutations in RT.

Background: The effective use of combination antiretroviral therapy (ART) has significantly improved the life expectancy of people living with the human immunodeficiency virus (HIV). However, complications have shifted from opportunistic infections to issues such as drug toxicity and resistance, as well as an increase in premature cardiovascular diseases (CVD). These conditions are attributed to chronic immune activation and persistent inflammation caused by HIV, along with lipid abnormalities and insulin resistance.

Background: On demand, topical PrEP is desired by those preferring episodic, nonsystemic PrEP. PC-1005 gel (MIV-150, zinc, and carrageenan) exhibits in vitro antiviral HIV-1, human papillomavirus (HPV), and herpes simplex virus type 2 (HSV-2) activity, attractive for a multipurpose prevention technology candidate. We evaluated the safety, pharmacokinetics, and antiviral effect of rectally applied PC-1005.

Tripterifordin and neotripterifordin are important ent-kaurane diterpenoids in the Chinese medicinal herb Tripterygium wilfordii, possessing significant anti-HIV(human immunodeficiency virus) activity. On the basis of elucidating the natural biosynthetic pathways of these compounds, heterologous production with microbial cell factories can help to alleviate the reliance on plant resources and provide abundant raw materials for sustainable production. TwKO is the first CYP450 enzyme involved in the biosynthesis of tripterifordin and neotripterifordin.

The integration of nanotechnology into antiretroviral drug delivery systems presents a promising avenue to address challenges posed by long-term antiretroviral therapies (ARTs), including poor bioavailability, drug-induced toxicity, and resistance. These limitations impact the therapeutic effectiveness and quality of life for individuals living with HIV. Nanodrug delivery systems, particularly nanoemulsions, have demonstrated potential in improving drug solubility, enhancing bioavailability, and minimizing systemic toxicity.
