Sponge isolates

Lacking an immune system, protective shell, or mobility, sponges have developed an ability to synthesize a variety of unusual compounds for survival. C-nucleosides isolated from Caribbean Cryptotethya crypta, were the basis for the synthesis of zidovudine (AZT), aciclovir (Cyclovir), cytarabine (Depocyt), and cytarabine derivative gemcitabine (Gemzar).

Semisynthetic analogs of the sponge isolate jasplakinolide, were submitted to National Cancer Institute’s Biological Evaluation Committee in 2011.

Other marine isolates

Trabectedin, aplidine, didemnin, were isolated from sea squirts. Monomethyl auristatin E is a derivative of a dolastatin 10, a compound made by Dolabella auricularia. Bryostatins were first isolated from Bryozoa.

Salinosporamides are derived from Salinispora tropica. Ziconotide is derived from the sea snail Conus magus.
