A University of Hawaiʻi<\/span> researcher has identified a rare bacterium that is active against certain cancers. The bacterium, Lentzea flaviverrucosa<\/em>, that produces petrichorin A, was discovered by Shugeng Cao<\/strong>, associate member of the Cancer Biology Program<\/a> at the 糖心视频<\/abbr> Cancer Center<\/a>, and co-investigators Chunshun Li<\/strong> and Xiaohua Wu<\/strong>, in collaboration with Joshua Blodgett of Washington University in St. Louis. The research team proved that petrichorin A is active against cancers such as ovarian cancer, fibrosarcoma, prostate cancer and T-cell leukemia. <\/p>\n

These findings were published in the Proceedings of the National Academy of Sciences of the United States of America<\/a><\/em>. <\/p>\n

Petrichorin A is a peptide that contains special amino acids, and each amino acid has a nitrogen-nitrogen bond. Petrichorin A, a dumbbell-like natural product, was evaluated for anti-cancer activity against multiple cancer cell lines. The researchers conducted a preliminary test and discovered that petrichorin A was not toxic to a normal human cell line. With this observation, his team proved that petrichorin A was active against ovarian cancer, fibrosarcoma, prostate cancer and T-cell leukemia. This highlighted the importance of including petrichorin A in future research of pharmaceutical design and discovery programs. <\/p>\n

“Cancer is the second leading cause of death in Hawai\u02bbi and nationally, after cardiovascular disease,” said Cao. “If petrichorin A were developed successfully, people in Hawai\u02bbi and the Pacific would benefit from our drug therapies.”<\/p>\n

Cao currently serves as a professor at the Daniel K. Inouye College of Pharmacy<\/a> (DKICP<\/abbr>) at 糖心视频<\/abbr> Hilo<\/a>. Wu is a senior research associate at DKICP<\/abbr>, and Li, a previous postdoctoral fellow in Cao\u2019s lab, is a scientist at Antheia, Inc.<\/p>\n
