Publication number: 20250129083Abstract: Imidazotetrazines were designed to evade resistance by O6-methylguanine DNA methyltransferase (MGMT) while retaining suitable hydrolytic stability, allowing for effective prodrug activation and biodistribution. One compound, called TABZ, exhibits activity against cancer cells irrespective of MGMT expression and MMR status. TABZ has comparable blood-brain barrier penetrance and comparable hematological toxicity relative to TMZ, while also matching its maximum tolerated dose (MTD) in mice when dosed once-per-day over five days. The activity of TABZ is independent of the two principal mechanisms suppressing the effectiveness of TMZ, making it a promising new candidate for the treatment of GBM, especially those that are TMZ resistant.Type: ApplicationFiled: February 1, 2023Publication date: April 24, 2025Applicant: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOISInventors: Paul J. HERGENROTHER, Timothy M. FAN, Riley L. SVEC, Sydney MCKEE

Patent number: 12234240Abstract: New synthetic methods to provide access to previously unexplored functionality at the C8 position of substituted imidazo[5,1-d][1,2,3,5]tetrazines of Formula I. Through synthesis and evaluation of a suite of compounds with a range of aqueous stabilities (from 0.5 to 40 hours), a predictive model for imidazotetrazine hydrolytic stability based on the Hammett constant of the C8 substituent was derived. Promising compounds were identified that possess activity against a panel of GBM cell lines, appropriate hydrolytic and metabolic stability, and brain-to-serum ratios dramatically elevated relative to TMZ, leading to lower hematological toxicity profiles and superior activity to TMZ in a mouse model of GBM.Type: GrantFiled: December 16, 2022Date of Patent: February 25, 2025Assignee: The Board of Trustees of the University of IllinoisInventors: Paul J. Hergenrother, Timothy M. Fan, Riley L. Svec

Publication number: 20240082241Abstract: Compositions and methods for the induction of cell death, for example, cancer cell death. Combinations of compounds and related methods of use are disclosed, including the use of compounds in therapy for the treatment of cancer and selective induction of apoptosis in cells. The disclosed drug combinations can have lower neurotoxicity effects than other cancer therapies that achieve the same or similar therapeutic effect.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Applicants: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS, VANQUISH ONCOLOGY, INC., THE JOHNS HOPKINS UNIVERSITYInventors: Paul J.

Patent number: 11926877Abstract: A saliva-based testing method that bypasses the need for RNA isolation/purification is described herein. In experiments with inactivated SARS-CoV-2 virus spiked into saliva, this method has a limit of detection of 500-1000 viral particles per mL, rivalling the standard NP swab method. Initial studies showed excellent performance with 100 clinical samples. This saliva-based process is operationally simple, utilizes readily available materials, and can be easily implemented by existing testing sites thus allowing for high-throughput, rapid, and repeat testing of large populations.Type: GrantFiled: June 17, 2021Date of Patent: March 12, 2024Assignee: The Board of Trustees of the University of IllinoisInventors: Diana Rose Ranoa, Robin L. Holland, Fadi G. Alnaji, Kelsie J. Green, Leyi Wang, Christopher B. Brooke, Martin D. Burke, Timothy M. Fan, Paul J. Hergenrother

Publication number: 20220226311Abstract: The blood-brain barrier penetrant procaspase-3-activating drug, PAC-1, has been identified as an effective approach to inducing immune stimulatory destruction of cancer cells. PAC-1 induces cleavage of MLH1 in cancer cells, and studies show that inactivation of MLH1 leads to increased mutational burden and neoantigen presentation by major histocompatibility complex (MHC) products. Herein is described a mechanistic-based strategy to bring the power of immunotherapy in an effective fashion for treatment of cancer.Type: ApplicationFiled: June 1, 2020Publication date: July 21, 2022Applicant: The Board of Trustees of the University of IllinoisInventors: Paul J.
