Marine sponges are the most primitive and simplest multicellular animals, with approximately 8900 known described species, although more than 15,000 species are thought to exist worldwide today. These marine organisms potentially represent the richest pipeline for novel drug leads. Mycale (Arenochalina) and Clathria are recognized marine sponge genera belonging to the order Poecilosclerida, whereas Biemna was more recently reclassified, based on molecular genetics, as a new order Biemnida. Together, these sponge genera contribute to the production of physiologically active molecular entities with diverse structural features and a wide range of medicinal and therapeutic potentialities. In this review, we provide a comprehensive insight and up-to-date literature survey over the period of 1976\u20132018, focusing on the chemistry of the isolated compounds from members of these three genera, as well as their biological and pharmacological activities, whenever available.<\/jats:p>","DOI":"10.3390\/md16060214","type":"journal-article","created":{"date-parts":[[2018,6,18]],"date-time":"2018-06-18T10:57:11Z","timestamp":1529319431000},"page":"214","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Chemistry and Biological Activities of the Marine Sponges of the Genera Mycale (Arenochalina), Biemna and Clathria"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6459-2955","authenticated-orcid":false,"given":"Amr","family":"El-Demerdash","sequence":"first","affiliation":[{"name":"Mus\u00e9um National d\u2019Histoire Naturelle, Mol\u00e9cules de Communication et Adaptation des Micro-organismes, Sorbonne Universit\u00e9s, UMR 7245 CNRS\/MNHN, CP 54, 57 Rue Cuvier, 75005 Paris, France"},{"name":"Organic Chemistry Division, Chemistry Department, Faculty of Science, Mansoura University, Mansoura 35516, Egypt"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9314-2697","authenticated-orcid":false,"given":"Mohamed A.","family":"Tammam","sequence":"additional","affiliation":[{"name":"Department of Pharmacognosy and Chemistry of Natural products, Faculty of Pharmacy, National and Kapodistrian University of Athens, Panepistimiopolis Zografou, Athens 15771, Greece"},{"name":"Department of Biochemistry, Faculty of Agriculture, Fayoum University, 63514 Fayoum, Egypt"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2545-0967","authenticated-orcid":false,"given":"Atanas G.","family":"Atanasov","sequence":"additional","affiliation":[{"name":"Department of Pharmacognosy, University of Vienna, 1090 Vienna, Austria"},{"name":"Institute of Genetics and Animal Breeding of the Polish Academy of Sciences, 05-552 Jastrzebiec, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1722-5954","authenticated-orcid":false,"given":"John N.
