Abstract

The presented work aimed to isolate some bioactive compounds from Red
Sea soft corals.
This thesis included Two Parts:
Part one: Nephthea sp.
Chemical investigations of the soft coral Nephthea sp. collected from the
Red Sea led to isolation of nine compounds: one new steroid, 4α,24R-dimethyl 5α-ergost-22E-en-3β, 8β, 18-triol (1), five known steroids (2-6), two known
sesquiterpenoids (7 and 8) and a known ceramides (9). Structures were elucidated
by employing extensive NMR and HR-EI-MS experimentation. The total extract,
fractions and compounds from Nephthea showed differential cytotoxicity against
breast cancer cells MCF-7.
