  • Patent number: 12285427
    Abstract: This invention establishes a new paradigm for treatment of Parkinson's disease (PD) by eliminating senescent cells that reside in or around the site of the disease pathophysiology. Exposure of test subjects to the herbicide paraquat (PQ) increases the risk for developing Parkinson's disease. The data in this disclosure show that PQ induces a senescence arrest and SASP in astrocytes, in culture and in vivo in mice, and senescent cell markers were present in astrocytes in midbrain tissue from PD patients. In a transgenic mouse model, senescent cell ablation protected against PQ-induced PD-like neuropathology. Removal of senescent cells from affected sites using small molecule agents that specifically target senescent cells can help prevent or ameliorate signs and symptoms of the disease.

  • Patent number: 11865123
    Abstract: This invention is based on the discovery that many eye conditions associated with aging are mediated at least in part by cells bearing a senescent phenotype. Senescent cells accumulate with age, and express factors that contribute to the pathophysiology of age related conditions. The data show that in age-matched patients, the severity of age-related conditions correlates with the abundance of senescent cells, and that clearing senescent cells can help abrogate the condition. Small molecule drugs that remove senescent cells from affected tissue in the eye are provided that have special efficacy in treating ophthalmic conditions. They not only inhibit progression of the disease, they can also reverse some of the pathophysiology—such as neovascularization and vaso-obliteration—that lead to vision loss. These senolytic agents have an appropriate dose and specificity profile to be effective in the clinical management of previously intractable ophthalmic conditions.

  • Publication number: 20200354336
    Abstract: This invention is based on the discovery that many lung diseases associated with aging are mediated at least in part by cells bearing a senescent phenotype. Senescent cells accumulate with age, and express factors that contribute to the pathophysiology of age related conditions. The severity of age-related conditions typically correlates with the abundance of senescent cells: thus, clearing senescent cells can help abrogate the condition: providing symptomatic relief, and potentially inhibiting disease progression. In accordance with this invention, a family of Bcl protein inhibitors has been developed for the treatment of lung diseases. These senolytic agents have an appropriate dose and specificity profile to be effective in the clinical management of previously intractable pulmonary diseases.

  • Publication number: 20200338094
    Abstract: A library of heterocyclic compounds has been screened to identify particular compounds that have high inhibitory capacity for the Bcl family of regulatory proteins. Compounds identified as Bcl antagonists have been further screened to select pharmaceutical agents with both high potency and high specificity for eliminating senescent cells in comparison with replicative or quiescent cells of the same tissue type. Particular structures are identified in this disclosure that eliminate senescent cells with an EC50 in the nanomole range and a specificity around or above 100-fold. In accordance with this invention, heterocyclic compounds provided in this disclosure can be formulated for the treatment of a range of age-related conditions caused or mediated by senescent cells. Such conditions are exemplified by ophthalmic conditions, pulmonary conditions, and osteoarthritis.
