Chemical Extracted From Poisonous Plant Could Lead To Novel Prostate Cancer Treatment

Chemical Extracted From Poisonous Plant Could Lead To Novel Prostate Cancer Treatment
GenSpera, Inc. recently announced that the United States Patent and Trademark Office has issued the company United States Patent Number 8,957,016. This patent represents an expansion of the firm's intellectual property portfolio claiming multiple compositions for GenSpera's pro-drugs thought to be activated by Prostate Specific Antigen (PSA), which can translate into major advances in the treatment against prostate cancer. GenSpera is currently developing several pro-drugs that bind to specific peptides with a very powerful cytotoxin that is isolated from Thapsia garganica, a poisonous plant. However, while the plant itself is poisonous, GenSpera believes that extraction of cytotoxin from the plant species can in fact significantly benefit prostate cancer patients. This prostate-specific antigen-targeting agent approach based on the cytotoxin extracted from Thapsia garganica intends to minimize side effects that are frequently observed with other therapies and, at the same time, maximize activity against tumors. This recent patent is related to GenSpera's platform technology that targets the activation of biologically active materials to cells capable of producing PSA and to a peptide that can not only be recognized but also removed by PSA to activate therapeutic pro-drugs. This patent will cover GenSpera's series of these PSA targeted pro-drugs until 2026. "We see significant potential for our investigational agents in prostate cancer. Prostate cancer treatments are currently dominated
