    摘要: The expression of the P-glycoprotein (P-gp) efflux transporter at the blood−brain interface impedes BBB penetrance of most small molecules. Designing efflux liabilities out of compounds can be laborious and there is no generalizable approach to transform periphery-limited agents to ones active in the CNS. A target-agnostic, prospective assessment of P-gp efflux using diverse compounds indicated a reduction in molecular size or appending a carboxylic acid that enabled evasion of P-gp efflux in cell-based experiments and in mice. Such strategy was applied to transform a periphery-limited V600EBRAF inhibitor, dabrafenib, into compounds that possess potent and selective anti-cancer activity, but now also evaded P-gp-mediated efflux. When compared to dabrafenib, the compound developed herein (everafenib) has superior BBB penetrance and superior efficacy in an intracranial mouse model of metastatic melanoma, suggesting it as a lead candidate for the treatment of melanoma metastases to the brain and gliomas with BRAF mutation.

    摘要: Synergistic drug combinations with the small molecule PAC-1 against uveal or cutaneous melanoma. There are no current targeted drug treatments for the mutations associated with uveal melanoma. Despite primary radiation or surgical therapy, up to 50% of patients eventually develop metastatic disease, for which there is no standard therapy nor treatment shown to improve overall survival. Drug combinations with PAC‑1 allow the use of lower dosages of this compound that result in cancer cell death in uveal melanoma. Drug combinations of PAC-1 with the kinase inhibitor entrectinib have shown a synergistic effect against uveal melanoma cell lines. Specifically, PAC-1 and entrectinib are synergistic against wild-type and mutant uveal melanoma cell lines (e.g., GNAQ and GNA11).

    摘要: Compounds and related methods for synthesis, and the use of compounds in therapy for the treatment of cancer and selective induction of apoptosis in cells are disclosed. Compounds are disclosed in connection with modification of procaspases such as procaspase-3, and particular embodiments are capable of direct activation of procaspase-3 and procaspase-7 to the effector forms of caspase-3 and caspase-7. Procaspase-3 levels can vary among cancer cell types; several types have relatively high levels and can have increased susceptibility to chemotherapy by compounds and methods herein. Therapeutic applications are relevant for a variety of cancer conditions and cell types, e.g. breast, lung, brain, colon, renal, adrenal, melanoma, and others.

    摘要: The technology disclosed herein provides (4aR,4bS,6aS,9aS,9bS)-1-(4-chlorobenzyl)-4a,6a-dimethyl-3,4,4a,6,6a,8,9,9a,9b,10-decahydro-1H-indeno[5,4-f]quinoline-2,5,7(4bH)-trione, identified as compound IB:10:D, and related compounds. Compound IB:10:D was discovered though screening a compound library for inhibitors of the enzyme SULT2B1b. This enzyme, which produces the product cholesterol sulfate, is overexpressed in cancer. The product acts as an immunosuppressant that results in suppression of the immune system's ability to clear tumor cells. Compounds related to IB:10:D were synthesized and shown to inhibit production of cholesterol sulfate. The discovered inhibitors of SULT2B1b provide new compounds and methods for immunotherapy and cancer treatment.
