- Anticancer Activity of the Marine-Derived Compound Bryostatin 1: Preclinical and Clinical Evaluation. Kowalczyk, Tomasz Staszewski, Marek Markowicz-Piasecka, Magdalena Sikora, Joanna Amaro, Catarina Picot, Laurent Sitarek, Przemysław Bryostatins Humans Animals Antineoplastic Agents Neoplasms Cell Proliferation Clinical Trials as Topic Cell Line, Tumor Apoptosis Protein Kinase C Bryostatin 1, a natural macrolide isolated from , is a potent modulator of protein kinase C (PKC) isoforms with promising anticancer properties. In numerous in vitro studies, bryostatin 1 has been shown to inhibit tumor cell proliferation and induce differentiation and apoptotic cell death in a wide range of cell lines, including leukemia, lymphoma, glioma, and solid tumors such as ovarian and breast cancer. Its antitumor activity, both as monotherapy and in combination with conventional chemotherapy, has been confirmed in in vivo models, where synergistic effects have been observed, including sensitization of tumor cells to cytostatic agents. Despite promising preclinical findings, phase I and II clinical trials have not yielded the expected results, suggesting limited efficacy of the macrolide as a single agent with a relatively favorable safety profile. Current research directions focus on optimizing dosing regimens, combining bryostatin 1 with other anticancer drugs and identifying predictive biomarkers of response. This article reviews the current state of knowledge on the anticancer effects of bryostatin 1, analyzing available data from in vitro, in vivo, and clinical trials and discussing potential directions for further translational research.
