Procaspase-activating compound 1 (PAC-1) is an o-hydroxy-N-acylhydrazone that induces apoptosis in cancer cells by chelation of labile inhibitory zinc from procaspase-3. PAC-1 has been assessed in a wide variety of cell culture experiments and in vivo models of cancer, with promising results, and a phase 1 clinical trial in cancer patients has been initiated (NCT02355535). For certain applications, however, the in vivo half-life of PAC-1 could be limiting. Thus, with the goal of developing a compound with enhanced metabolic stability, a series of PAC-1 analogues were designed containing modifications that systematically block sites of metabolic vulnerability. Evaluation of the library of compounds identified four potentially superior candidates with comparable anticancer activity in cell culture, enhanced metabolic stability in liver microsomes, and improved tolerability in mice. In head-to-head experiments with PAC-1, pharmacokinetic evaluation in mice demonstrated extended elimination half-lives and greater area under the curve values for each of the four compounds, suggesting them as promising candidates for further development.

Page/Page column 32-33, (2008/06/13)
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.
