The presence of two known anthraquinones, Lupinacidin A and Galvaquinone B, which have antitumor activity, has been identified in the sea anemone (Gyractis sesere) from Easter Island. So far, these anthraquinones have been characterized from terrestrial and marine Actinobacteria only. In order to identify the anthraquinones producer, we isolated Actinobacteria associated with the sea anemone and obtained representatives of seven actinobacterial genera. Studies of cultures of these bacteria by HPLC, NMR, and HRLCMS analyses showed that the producer of Lupinacidin A and Galvaquinone B indeed was one of the isolated Actinobacteria. The producer strain, SN26_14.1, was identified as a representative of the genus Verrucosispora. Genome analysis supported the biosynthetic potential to the production of these compounds by this strain. This study adds Verrucosispora as a new genus to the anthraquinone producers, in addition to well-known species of Streptomyces and Micromonospora. By a cultivation-based approach, the responsibility of symbionts of a marine invertebrate for the production of complex natural products found within the animal’s extracts could be demonstrated. This finding re-opens the debate about the producers of secondary metabolites in sea animals. Finally, it provides valuable information about the chemistry of bacteria harbored in the geographically-isolated and almost unstudied, Easter Island.

Background: Cancer is a major public health concern, and is one of the leading causes of death globally. Surgical removal, chemotherapy or hormonal therapy, radiation therapy, or a combination of them are treatment for cancer, many of which are ineffective or have serious side effects. In view of this, there is a search for new, more effective alternatives for cancer prevention and treatment. One possible source of compounds are natural products; among them, terpenes, a large class of organic compounds, have shown promise due to their anti-inflammatory, anti-tumorigenic, and hypolipidemic properties, among others recorded in the literature. Objective: The study aims to use a patent review to evaluate the development and use of terpenes, or formulations containing terpenes, in new therapeutic options for the treatment of various types of cancer. Methods: This patent review was carried out using the specialized patent databases of WIPO and Espacenet. The selection of patents was based on the following inclusion criteria which included pre-clinical and/or clinical trials, and demonstrated anti-tumor effects. Results: Eight patents were identified, six from China, and two from Japan. In this review, all patents confirmed having good antitumor activity for many types of cancer cells. In addition, the inventors indicate more studies pre-clinical and clinical trials giving greater clarity and accurate reflection of the activity of the products studied. Conclusion: Natural products are an important source of compounds for use in the fight against cancer that can act synergistically, and help in the treatment of cancer.
