New species of Microscleroderma and Amphibleptula (Demospongiae, Tetractinellida, Scleritodermidae) from two contrasting marine environments

Autor: Patricia Gómez, Carlos González-Gándara, María De Los Angeles Rojas-Terán, Fernando Calderón-Gutiérrez

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. 101:241-251

We record for the first time a nominal species of the genus Microscleroderma in the Western Atlantic, and the first record of the genus Amphibleptula in Mexico. Two new species of ‘lithistid’ Tetractinellida are described: Microscleroderma mexica

Two new lithistids (Porifera: Demospongiae) from a shallow eastern Mediterranean cave (Lebanon)

Autor: H Zibrowius, Thierry Perez, Ghazi Bitar, Jean Vacelet

Publikováno v: Journal of the Marine Biological Association of the UK. 84:15-24

Two new species of lithistid sponges, Gastrophanella phoeniciensis sp. nov. (Siphonidiidae) and Microscleroderma lamina sp. nov. (Scleritodermidae) are described from a submarine cave, depth 2–3 m, in Lebanon. They are the first Mediterranean recor

Synthesis of a model bicyclic core related to Microscleroderma spirophora steroids

Autor: Ulf Peters, Anand Mayasundari, David G. J. Young

Publikováno v: Tetrahedron Letters. 44:2633-2636

An approach to the strained B,C-bicyclic nucleus of a heterocyclic class of steroids is described. The approach relies on a sigmatropic shift for installation of the strained bridge.

Microsclerodermins F–I, Antitumor and Antifungal Cyclic Peptides from the Lithistid Sponge Microscleroderma sp

Autor: Patrick L. Colin, Asfia Qureshi, D. John Faulkner

Publikováno v: Tetrahedron. 56:3679-3685

Four new cyclic peptides, microsclerodermins F–I (6–9), were isolated from the deep water lithistid sponge Microscleroderma sp. from Palau. Their structures, which incorporate an unusual long chain β-amino acid, were elucidated using spectroscop

Microsclerodermins C - E, antifungal cyclic peptides from the lithistid marine sponges Theonella sp. and Microscleroderma sp

Autor: D. John Faulkner, Eric W. Schmidt

Publikováno v: Tetrahedron. 54:3043-3056

Three new cyclic peptides, microsclerodermins C - E (3–5), were isolated from two species of lithistid sponges from the Visayan Islands, Philippines. The sponge Theonella sp. contained peptides 3 and 4, while Microscleroderma sp. contained peptides
