Sulfanylbenzamide thioesters are molecules with anti-HIV activity that disrupt zinc coordination in the viral protein NCp7. These molecules are useful as topical microbicides; however, they are too unstable to be used systemically. In this article, a nitroimidazole prodrug was used to protect the sulfanylbenzamide to convey blood stability and oral bioavailability to the molecule. Studies on the molecule called nipamovir were performed to assess the rate of prodrug cleavage, antiviral activity, mechanism of metabolism, and pharmacokinetics in several different species. An efficient and inexpensive synthesis of nipamovir is also described. The results indicate that nipamovir could be further developed as a new type of drug to treat HIV infection.

Radionuclides used for imaging and therapy can show high molecular specificity in the body with appropriate targeting ligands. We hypothesized that local energy delivered by molecularly targeted radionuclides could chemically activate prodrugs at disease sites while avoiding activation in off-target sites of toxicity. As proof of principle, we tested whether this strategy of radionuclide-induced drug engagement for release (RAiDER) could locally deliver combined radiation and chemotherapy to maximize tumor cytotoxicity while minimizing off-target exposure to activated chemotherapy.

The repurposing of statins as neuroprotective agents and/or anti-brain tumor drugs is limited by challenges in brain bioavailability and systemic off-target effects. Therefore, improved and targeted delivery of statins to the brain is necessary. This study aimed to develop a high-strength liquid formulation of the poorly soluble prodrug simvastatin for intranasal administration, as a strategy to achieve high brain concentrations of the prodrug and/or its active form, tenivastatin.

Hypoxia-tolerant polymeric photosensitizer prodrug for cancer photo-immunotherapy.

Although photodynamic immunotherapy represents a promising therapeutic approach against malignant tumors, its efficacy is often hampered by the hypoxia and immunosuppressive conditions within the tumor microenvironment (TME) following photodynamic therapy (PDT). In this study, we report the design guidelines towards efficient Type-I semiconducting polymer photosensitizer and modify the best-performing polymer into a hypoxia-tolerant polymeric photosensitizer prodrug (HTPS) for cancer photo-immunotherapy. HTPS not only performs Type-I PDT process to partially overcome the limitation of hypoxic tumors in PDT by recycling oxygen but also specifically releases a Signal Transducer and Activator of Transcription-3 (STAT3) inhibitor (Niclosamide) in response to a cancer biomarker in the TME.

Glycoconjugates of adefovir and tenofovir as asialoglycoprotein-mediated Anti-HBV prodrugs with enhanced liver targeting.

Hepatitis B virus (HBV) infection remains a significant global health challenge, often leading to severe liver complications such as cirrhosis and cancer. Current treatments rely heavily on nucleos(t)ide analogues like adefovir and tenofovir due to their potent antiviral effects. However, their clinical utility is limited by insufficient liver targeting, leading to off-target side effects, particularly nephrotoxicity.

Self-assembled nanoparticles of rapamycin prodrugs for the treatment of multiple sclerosis.

Optimizing the design of nanoparticulate co-delivery systems of antigens and immunomodulators to induce antigen-specific immune tolerance effectively remains a challenge, constrained by low drug loading capacity and premature leakage of active ingredients. Here, we report a prodrug self-assembled nanoparticles (NPs) strategy to synergistically deliver antigen and rapamycin (RAPA) into antigen-presenting cells (APCs) by simply conjugating rapamycin with an aliphatic chain. These prodrug NPs can be efficiently taken up by APCs and then release rapamycin through cleavage of the linker by intracellular esterase.
