Abstract: A method is disclosed for regenerating connective tissue by administering a scaffold comprising collagen fibers extracted from a soft coral. The length of the soft coral collagen fibers following stretching by about 15% is identical to the length of the fibers prior to stretching.

Abstract: An isolated collagen fiber is disclosed, wherein a length of the fiber prior to stretching by about 15%, is identical to a length of the fiber following said stretching by about 15%. The fiber comprises a Nuclear Magnetic Resonance (NMR) spectroscopic profile as shown in FIG. 1. Uses thereof and method of isolating are also disclosed.

Abstract: Salarines and Tulearins isolated from Fascaplysinopsis sp. sponge and synthetic derivatives thereof are provided.

Abstract: Disclosed are the compounds Asamarine A and B, novel cytotoxic diterpene-alkaloids, that have been isolated from the sponge Raspailia sp. The structure of these compounds have been established on the basis of NMR data and confirmed by X-ray analysis. Also disclosed are compounds (I) and (II), wherein wherein R1 represents hydrogen or lower alkyl or lower alkanoyl; R2 represents hydrogen or lower alkyl; R3 is either an alkyl or a cycloalkyl group containing one or more isoprene units, or a monoterpene or a sesquiterpene or a sesquiterpene or a diterpene group; R4 or R5 represent hydrogen or lower alkyl; R6 represents lower alkyl; and X represents F or Cl or Br or I.

Abstract: Biological applications of synthetic and natural alkaloids derived from the tunicate Eudistoma sp. are disclosed. A method regulating cell growth includes contacting one or more cells with an effective concentration of a compound for regulating cell growth. These compounds include: Segoline A, Segoline B, Isosegoline A, Norosegoline, Debromoshermilamine, Eilatin, 4-methylpyrido[2,3,4-kl]acridine, pyrido[2,3,4-kl]acridine, 1-acetyl-2,6-dimethylpyrido[2,3,4-kl]acridine, and derivatives and combinations of these compounds. An effective concentration range for using these compounds can range from approximately 0.1 .mu.M to 100 .mu.M. The effective concentration range for Eilatin, the most potent of these compounds is from 0.01 .mu.M to 0.99 .mu.M, and the effective concentration range for the other compounds of the present invention is from about 1.0 .mu.M to 100 .mu.M.
